CaseBlink vs Parley: how they compare in 2026

CaseBlink is AI case preparation for US immigration attorneys. Its models tag, label and extract data from client documents and check them for missing context, duplicates and inconsistencies. They search AAO and BIA decisions, case law and the USCIS Policy Manual, fill USCIS forms from intake and uploaded documents, and draft support letters, reference letters and briefs in the firm's voice. They read an RFE notice to map evidence to each request and draft the response. The Autopilot agent runs that sequence from upload to a tabbed filing packet in one pass. The Core plan at $200 per seat is where the AI lives. The Lite plan at $100 covers categorization, exhibit lists and one click PDF export, which are largely workflow, and the Pro plan in beta adds case management around the AI. For a firm buying Core or above, removing the models leaves very little.

Built around AI, the platform is defined in the Terms of Service as a system that ingests and stores content and applies AI to extract information, generate drafts, populate records and execute agentic tasks. Parley's home page describes an agent that drafts, fills forms and researches from a firm's own templates and past work, over a client and matter database that fills itself from email and calendar. Around that sits conventional practice software: case tracking with USCIS status updates, exhibit assembly into a combined, paginated PDF, form completion screens and LCA and PAF management.

CaseBlink says every output cites directly to the client's uploaded case documents and its research, so the attorney can check each statement at its source. It names what the research draws on: AAO and BIA decisions, case law, the USCIS Policy Manual and government resources. Its quality checker reviews uploaded evidence for missing context and inconsistencies before drafting. No number is published: no citation accuracy rate, no rate of unsupported statements, no test set and no approval outcome. The Service Agreement lists ways AI output can go wrong, including errors, misleading content and weak reasoning on complex tasks, and disclaims any warranty of the accuracy of output.

The vendor's content subdomain says drafts are generated directly from uploaded evidence, tie statements to verifiable facts and insert direct quotations from reference letters. The main site says the agent works from a firm's own templates and past samples. No accuracy figure, test set or evaluation is published, and no failure mode is named. Nothing describes how a draft links a statement back to the document it came from, or what the research function does when it finds no support. The privacy policy says AI output may be inaccurate or incomplete and must be reviewed by a qualified human, and the terms disclaim any warranty that generated content is accurate. The vendor's own practice guide discusses hallucination risk at length as a professional duty.

Autopilot organizes documents, reviews evidence, conducts research, writes drafts and assembles the filing packet in one click, then hands the attorney a complete packet to review before anything is filed; CaseBlink does not file on its own. Each statement in a draft cites to the uploaded evidence or research behind it, which gives the reviewing attorney a way to check the work line by line. The page for individual applicants says an expert attorney prepares the case using CaseBlink under their supervision. No control inside the automated run is published: no confidence signal on a weak draft, no point where Autopilot stops for a decision, and no route for flagging an error back to the vendor. The Service Agreement says CaseBlink may review output before it is returned but does not promise to, and places the risk of relying on output with the customer.

The privacy policy states that a qualified human user must review output generated by AI before relying on or using it. The terms say the services are tools intended to assist and not a substitute for professional judgment, and require the customer to set up independent verification procedures. The vendor's practice guide lays out a sequence of draft, verify and edit, then file. Drafts land in Microsoft Word and Outlook where the lawyer edits them. Parley's home page says the client and matter database automatically updates and fills out fields from emails, meetings and uploaded documents, and nothing states whether those record changes pass a review point. No mode, threshold or categorical limit on what the agent may do alone is published.

Logos of firms including Dorsey & Whitney, Dickinson Wright, Fakhoury Global Immigration, Clark Lau and Cline Williams appear on CaseBlink's site, which runs a testimonials page with named attorneys. Its page for individual applicants refers to partner firms that review cases prepared on the platform. It reports more than 100 firms, 1,000 users and 3,000 cases prepared, up from more than 50 firms and 1,000 cases in March 2025, and announced a $2 million funding round on its blog. No outcome evidence is published: the claim of filing five times faster has no method or sample behind it, and no approval rates, RFE rates or time per petition are reported for any named firm.

The about page names Erickson Immigration Group as relying on the platform. It points to Business Insider reporting in which a partner there describes using it for EB-1, O-1 and national interest waiver support letters, and it names Boundless as a partner using the platform with its legal team. Parley's home page says the product is trusted by more than 100 legal teams. No figure is published for what changed at any named firm, and the 100 teams are not identified. No case study with a method is published on the main site, and productivity benchmarks appear only on the vendor's content subdomain without a named customer.

The Service Agreement (effective 15 July 2026) says third party AI tools acting for CaseBlink retain no customer data and that output generated from customer data is itself customer data. Section 5 carries mutual confidentiality obligations, including notice before any compelled disclosure, and the data processing agreement has customer personal data deleted within 90 days of termination. The security page adds isolated tenant environments, data purged immediately after each model operation, no model training on client content, and a zero data retention agreement with OpenAI available on request. Section 1.4 licenses CaseBlink to copy, create derivative works of and otherwise use customer data to improve and develop its products and to create anonymized aggregated data, on a platform holding asylum declarations and medical evidence. Neither the agreement nor the security page addresses attorney client privilege or work product.

The Terms of Service limit Parley's license to customer content to providing the services and testing, diagnostics and troubleshooting. They state that Parley shall not use customer or generated content to train, fine tune or develop models deployed for or accessible by other customers (3.3). Customer content is defined as the customer's confidential information, protected by a clause that requires Parley to inform the customer immediately in writing before any compelled disclosure (6.1). Parley's pricing page lists zero data retention and no model training on the Starter plan. The vendor's practice guide discusses attorney client privilege and work product at length, including United States v. Heppner and Warner v. Gilbarco, but does not state how Parley's own terms preserve either for a firm using it. No segregation between users or matters is documented, the model providers are not named in any published document, and the training bar covers models other customers can use, leaving training for a single customer open.

Section 6.2 of the Service Agreement says that material provided by CaseBlink or its representatives is for general information, is not legal advice and creates no attorney client relationship, and the website terms repeat it; the agreement describes the service as a tool for legal professionals and puts responsibility for reviewing output on the customer. Section 6.3 lists the limits of AI output in plain terms. The product is sold to immigration attorneys, paralegals and corporate immigration teams, and every draft is framed as work the attorney reviews before filing. The exception is the page for individual applicants, which takes a foreign national's intake form and documents, structures them into a case file for partner firms to assess, and matches the applicant with a vetted partner firm. It says the attorney prepares the case under their supervision, but carries no not legal advice statement of its own and does not say whether partner firms pay for the introduction.

The terms state that the services and generated content are tools intended only to assist and are not a substitute for professional judgment. They define authorized users as the customer's employees, such as attorneys and paralegals, and bar use to serve other firms. The vendor's guide Should you use AI as a legal practitioner?, updated 14 July 2026, walks through ABA Formal Opinion 512 on competence, confidentiality, verification and client disclosure. It lists what attorneys remain responsible for, including supervision of junior lawyers and staff who are not lawyers using AI, and points to trackers of state bar guidance and court orders. Nothing states which jurisdictions or practice areas the product is built for or where it stops. The guide tells lawyers to check state rules rather than stating how the product fits them.

Section 6.3 of the Service Agreement lists the ways AI output can fail, including factual errors, a lack of empathy, bias carried over from training data and weak reasoning on tasks that need judgment. It makes the customer responsible for any bias audits, notices or consents that apply where AI processes personal data. What sits behind that on CaseBlink's side is not described. No one is named as accountable for the drafting and research models, and nothing says how a change to prompts, templates or the underlying model is tested before firms see it. No evaluation is published of how drafts and RFE responses perform across visa categories, nationalities or the languages of source documents. The security page's 52 controls cover information security, not model behavior, on a product whose drafts argue that a person qualifies for a visa.

The privacy policy has a dedicated section on artificial intelligence and automated processing. It describes what the AI does and states that output must be reviewed by a qualified human. It commits not to use customer content to train models available to other customers, and states that Parley makes no decisions with legal or similarly significant effects based solely on automated processing. Nothing names who inside the company owns model behavior, what is tested before a release, or what has been found about uneven output across case types or applicants. The product drafts immigration petitions for people of many nationalities. A claim about minimizing bias appears only on the content subdomain, without a mechanism.

The Service Agreement (effective 15 July 2026) binds the third party AI tools acting for CaseBlink to retain no customer data, and the security page says data is purged immediately after each model operation. The data processing agreement has customer personal data deleted within 90 days of termination, commits CaseBlink to remediate a personal data breach promptly and notify the firm without undue delay with assistance on its own notices, lists its subprocessors, Google LLC, OpenAI OpCo LLC and Slack Technologies LLC, with 15 days' notice before any new one gains access and a right to object, and grants audit rights that a current SOC 2 Type 2 report can satisfy. The security page adds AES 256 encryption at rest and in transit, isolated tenants, single sign on, role based access, audit logs for sensitive operations, continuous threat monitoring and disaster recovery backups. The breach clause sets no fixed hour window.

The privacy policy, updated 8 September 2026, states retention periods by category of information. It ties customer content retention and deletion to the customer agreement and to the product's functions for deleting accounts and downloading content. Customers may request their content for 30 days after a subscription ends, after which Parley may delete it (terms 2.4). The policy describes encryption in transit and at rest, access controls and security assessments. A dedicated incident section commits to prompt investigation and to notify customers under the customer agreement or data processing terms. The policy states that the current subprocessor list is published at trust.parley.so and that customers will get notice of new subprocessors that touch their content as the agreement requires. The Data Processing Addendum the policy refers to is not published on the site.

Section 7 of the Service Agreement caps CaseBlink's total liability at the fees paid in the twelve months before the claim, cumulative rather than per incident. It raises the cap to twice that amount for breaches of the data security terms or confidentiality involving customer data. Section 8 has CaseBlink indemnify the firm against third party claims that the service infringes intellectual property. Output is carved out of all of this. The agreement disclaims any warranty of the accuracy or authenticity of output and any liability for actions taken based on it, and has the customer indemnify CaseBlink for claims arising from its use of output. A petition denied because a drafted brief misstated evidence or cited a decision wrongly would fall on the firm.

Professional performance is warranted in the Terms of Service, with reperformance as the remedy (7.1). They give an indemnity against third party claims that the services violate law or infringe copyright, trademark or US patent, or arise from Parley's fraud, gross negligence or willful misconduct (8.1). Liability is capped at fees paid in the prior twelve months, or one hundred dollars during a free trial (9). The terms disclaim any warranty that generated content is accurate, complete or compliant and exclude generated content from the indemnity. They state that Parley has no liability for the accuracy of generated content or results obtained from using it. No insurance position is published.

Drafts leave CaseBlink as Word files and filing packets as tabbed PDF. It supports single sign on through SAML 2.0 and OIDC with Okta, Azure AD and Google Workspace, including central provisioning and deprovisioning, and the Service Agreement refers to API access. Its answer to case management is to build its own. The Pro plan, in beta at $300 per seat, adds client intake, profiles, a data repository, calendars and dependents tracking inside CaseBlink, and Enterprise offers custom integrations and a white label client portal. No connection is named to the immigration case management systems firms already use, such as INSZoom, Docketwise, eImmigration, LawLogix or Imagility, or to document management systems, and the API is not documented. A firm keeping its existing case system would move documents in and drafts out by hand.

Parley's home page names Microsoft Outlook and Word, where users delegate work to the agent, and Google Drive, Box and Dropbox for documents. It says connecting email and calendar populates the client and matter database from emails and meetings. The terms define a Microsoft Word plugin and a Parley API, which Parley may make available at its discretion. The content subdomain describes a USCIS case status API in beta. No document management system such as iManage or NetDocuments is named, no immigration case management system is named, and no implementation documentation describing direction of sync or configuration is published.

Google Cloud Platform hosts the service in isolated tenant environments, with encryption at rest and in transit, continuous monitoring and replicated disaster recovery backups, as CaseBlink's security page describes. The data processing agreement's subprocessor schedule places every listed processor, Google, OpenAI and Slack, in the United States, so a firm on a standard plan knows its data is processed in the US. The Enterprise plan, for 15 or more users, adds private hosting, a white label portal and data residency options. The isolated tenant design addresses separation between firms. Which regions the Enterprise residency option covers, and whether private hosting means a dedicated cloud project or on premises, is not published.

Parley hosts the platform in the cloud and gives the customer internet access to it, as the terms describe. The privacy policy says Parley is based in the United States and may process personal information in the United States and other countries where it, its affiliates or subprocessors operate, relying on the EU-U.S. Data Privacy Framework for transfers. No tenancy model is stated, no region is offered, and processing location is not separated from storage. A private cloud deployment option is claimed only on the vendor's content subdomain.

A SOC 2 Type 1 audit in 2024 and a SOC 2 Type 2 audit in 2025 are complete, with annual audits, regular third party penetration tests, a vulnerability disclosure program and staff security training, according to CaseBlink's security page. It lists its controls by family, access control, business continuity, change management, incident response and information security, 52 in all. The audit reports and its zero data retention agreement with OpenAI can be requested through its trust center at trust.caseblink.com. The data processing agreement lets a current SOC 2 Type 2 report stand in for a customer audit, which ties the attestation to the contract. The security page describes the platform as SOC 2 Type 2 compliant and certified, though SOC 2 produces an auditor's report rather than a certificate. No auditor or report period is named publicly.

The security section of Parley's home page lists SOC 2 Type II, GDPR and no AI model training. The privacy policy, updated 8 September 2026, says the security program is designed to align with industry standards including SOC 2 Type II controls, which is not a statement that an audit has been completed. The vendor's content subdomain says a report issued by an auditor is available under NDA on request, and that the auditor and control period are disclosed only with it. The trust center is at trust.parley.so. No auditor, report period or scope is published on any open page. The label and the policy do not match.

The data processing agreement's subprocessor schedule names OpenAI OpCo, LLC as the third party AI provider, processing in the United States, alongside Google LLC for hosting and Slack Technologies LLC. CaseBlink must give at least 15 days' notice before any new subprocessor can access customer personal data, with seven days for the firm to object on reasonable grounds. The security page describes a zero data retention agreement with OpenAI, available on request, under which data is not retained after each operation and is not used for training. A firm can tell its clients from a document it signs which companies see their passports, employment records and asylum declarations. The specific OpenAI models and versions behind drafting, research and extraction are not named, and a change of model within OpenAI would not trigger the notice.

AI models used with the service count as third party materials under the terms. The privacy policy commits to notice when a new subprocessor will touch customer content, as the customer agreement requires. The vendor's data protection guide explains how model providers, subprocessors and cloud hosts handle data under zero data retention agreements, and Parley's pricing page lists zero data retention, but neither says which providers Parley uses. The privacy policy says the current subprocessor list is published at trust.parley.so. No model or provider is named on Parley's open pages.

Prices, units and plan contents are published. Lite costs $100 per seat per month ($92 billed annually) for document categorization, labeling, quality checks, exhibit lists and tabbed PDF export; Core costs $200 per seat per month ($183 annually) and adds AI research, drafting, form filling, RFE responses and the Autopilot agent; Pro costs $300 per seat per month ($275 annually) and adds case management, now in beta. Every plan includes unlimited cases and a 14 day free trial, annual billing includes one month free, and Enterprise, for 15 or more users with private hosting, a white label portal and dedicated support, is priced on request. The Service Agreement sets out the rest of the commercial terms: one seat per named person, reasonable use limits, trial cancellation, automatic renewal and notice of fee changes. Cases are unlimited per seat, in a category often priced per case.

Parley's pricing page lists Starter at $500 a month for up to ten seats in a shared workspace. Starter includes a set amount of usage credits, agentic drafting, research, forms and review, Outlook and Word integrations and zero data retention. Enterprise is on request, with unlimited seats, credits sized to the firm, SSO and deployment support. The Terms of Service publish the billing mechanics in detail: monthly billing in advance or annual prepayment, included credits, and additional credits at a list price set on the order. Unused credits roll over up to twice the monthly allotment, plans renew automatically, a free trial converts to a paid plan unless canceled, and late payments carry a charge of 1.5 percent a month. The credit list price and any implementation cost are not published.

CaseBlink is built only for US immigration law. It covers employment visas (H-1B, L-1, O-1, TN, E-2 and E-3), employment green cards (EB-1A, EB-1B, EB-1C, EB-2 NIW, PERM and EB-3), family based petitions, humanitarian cases including asylum, DACA, TPS and U and T visas, naturalization, and RFE responses across them. It is sold to solo practitioners, high volume immigration practices, paralegals and corporate immigration departments. Plans are per seat, from a single user up to Enterprise for 15 or more, and named customers run from boutique immigration firms to Dorsey & Whitney. A separate service matches foreign nationals with partner firms that use the platform. Nothing published says where drafting or research is less reliable, for instance humanitarian narratives against employment petitions, or which forms Autopilot cannot yet assemble end to end. Removal defense is not mentioned at all.

The pricing page separates solo practitioners and small teams on Starter from firms needing governance and SSO on Enterprise, and the terms define users as attorneys and paralegals. The support page lists immigration workflows: research and analysis, form filling, drafting, case tracking, LCA and PAF management and RFE responses, and invites immigration practitioners to book a demo. Parley's home page has broadened to legal teams generally without naming other practice areas, so the scope beyond immigration is claimed rather than shown. The content subdomain lists visa categories, including O-1A, EB-1, EB-2 NIW, H-1B, TN, L-1 and E-2. Nothing states which case types or practice areas the product does not handle.
