Truth Systems
Truth Systems is a San Francisco company, founded in 2023, that sells AI governance software to law firms. Its first product, Charter, runs as a browser extension and desktop agent on firm machines and checks each prompt a lawyer submits to an AI tool against firm policy and client rules before it is sent, blocking privileged or sensitive material or the wrong tool for a matter and showing the user a warning. The vendor says Charter's compliance AI agent reads a firm's policies and each client's outside counsel guidelines as written and converts them into rules applied matter by matter.
Charter also records which tool, prompt and response were used on which matter, and its Insights dashboard reports AI use and time by tool, office, person, client and matter. A second product, Alexandria, is an MCP gateway that connects firm systems such as Intapp, iManage, Aderant and Microsoft 365 into one layer for AI agents, checking each agent action against ethical walls and client restrictions. Arnall Golden Gregory is named as a customer.
The cofounders are Alex Mac, the chief executive, and Nam Nguyen, the chief operating officer. The company was part of Y Combinator's Summer 2025 batch and announced a $4 million seed round led by Gradient, with Lightspeed, F-Prime and Y Combinator participating.
Capability grades
All 15 axes, graded from public sources on the date shown. Hover a grade to see what the letter means on that axis.
AI Centrality
How much of the product is actually AI. Whether the machine learning is the mechanism the buyer is paying for or a feature layered onto conventional software, and whether the vendor is specific about which is which.
The compliance agent Truth Systems describes reads a firm's policies and its clients' guidelines and turns each mandate into live access controls, matter by matter, and the dashboard classifies AI use by use case. Without the agent, a browser extension, desktop agent, rule engine, dashboard and audit log remain, which is most of what a firm deploys. Every block or warning a lawyer sees depends on how the agent read a client's guidelines. Alexandria applies the same checks to AI agents, with every tool call checked against the agent's identity.
Citation Accuracy and Hallucination Disclosure
Whether the vendor publishes measured accuracy on citations and assertions, grounds output to primary sources, and says plainly what its system does when it does not know. Legal has a documented public record of fabricated citations reaching filed briefs, so an untested claim of accuracy is not evidence.
Truth Systems says Charter catches what crosses the line before the damage is done, and a product mockup on its home page counts 276+ prevented incidents, with no method or named firm attached. Nothing published says how often the agent misreads a client guideline, how often a prompt that should have been stopped gets through, or how often a legitimate prompt is blocked. The product cites no legal authority, so grounding takes a different form here: the rules it enforces come from its own reading of client guidelines, and nothing says whether each rule links back to the passage it was drawn from.
Autonomy and Oversight Model
What the system decides on its own, what a lawyer must approve, and whether the vendor documents where the review point sits. A tool that drafts under review and a tool that files without one are different products and different risks.
Charter checks each prompt before it leaves the browser and blocks it or warns the user, and Truth Systems says it turns each client mandate into live access controls, matter by matter. A dashboard and audit log let the firm see what was blocked. No review step over the agent's work is published: nothing says whether a person confirms the rules the agent derives from a client's guidelines before they are enforced, what happens when a guideline is ambiguous, or how a lawyer can challenge a block on a live matter.
Alexandria's agents are described as acting under a real identity, with every tool call checked against it, and no human review step is described.
Operational and Outcome Evidence
Named, dated evidence that the product works in production at real firms or legal departments. Case studies with figures and identified customers count. Unattributed testimonials and launch announcements do not.
The home page carries quotes from three people at Arnall Golden Gregory, alongside a customer story video. Sean Fogarty, a managing partner, says what Charter gives the firm is transparency. Jennifer Waite, chief knowledge and innovation officer, says clients want to know exactly how the firm works with AI on their matters: which tool was used, what it did and how much time it saved. Alexander Hughes, director of information governance, says the firm is not worried about data leakage because it monitors, watches, stops and redirects it.
At its August 2025 launch the vendor said it worked with two law firms with $2 billion in combined revenue and nearly 1,500 attorneys. Product mockups on the home page show counts such as 276+ prevented incidents and a 51 percent rise in hours spent on AI, with no named firm or method. No figure with a method is published: how many incidents were prevented at a named firm, over what period, and against what baseline.
Privilege and Confidentiality Posture
How client confidences are handled: attorney client privilege and work product treatment, segregation of one client matter from another, whether client data trains any model, and what the vendor commits to in writing rather than in marketing.
Charter captures real sessions, so the vendor's system holds privileged material from every AI interaction it monitors. Access controls, custom retention, single tenant architecture and deployment on premises are offered. Nothing says whether captured prompts train any model, whether a model provider processes them when a prompt is evaluated, or how blocked privileged content is itself stored. No terms of service, privacy policy or security page is published.
UPL and Professional Responsibility Posture
Whether the vendor is clear that it supplies a tool rather than legal advice, who its audience is, and how it addresses unauthorized practice of law, competence and supervision duties, and jurisdiction limits. ABA Formal Opinion 512 is the reference point. Where the advice line is not the duty a product raises, the axis is read through the nearest professional duty it does raise: judicial conduct rules and the reviewing duty for products sold only to courts, and the duty to bill for time actually spent for products that draft time entries.
Nothing published says where the product's judgment stops and the firm's begins. There are no terms of service or usage policy on the site. The product gives clients no legal advice, but it does interpret a law firm's obligations: its agent reads each client's guidelines and decides which prompts to allow, and nothing says the firm remains responsible for that reading or should confirm it. The product is sold to law firms.
AI Governance and Bias Disclosure
Published governance over model behavior: who owns it inside the vendor, what is tested before release, and what is disclosed about disparate output across matter types, parties, or populations.
No governance position is published for the vendor's own AI. The product governs other vendors' AI tools, and nothing describes how Truth Systems governs its own: who is accountable for the agent's reading of client guidelines, what is tested before a release, or how errors and uneven results are found and disclosed. A firm relying on Charter to enforce its clients' mandates relies on that agent to read them correctly.
AI Safety and Data Stewardship
Retention, deletion, access control, and what happens to prompts and documents after they are processed. Whether the vendor states its subprocessors and its incident practice, or leaves the buyer to assume.
Truth Systems' home page names single sign on, IP allow listing, granular access by role, and data lifecycle and retention controls. No privacy policy, subprocessor list, deletion commitment, encryption statement or incident practice is published, for a system that captures prompts and responses from every AI tool a firm uses.
AI Liability and Recourse
What the vendor stands behind contractually when its output is wrong. Indemnities, caps, carve outs, insurance, and whether any of it is published or only reachable through a negotiated agreement.
Nothing is published on who bears the loss when the product is wrong. No terms of service or customer agreement is published, so no warranty, indemnity or liability cap can be read before signing. If Charter lets a privileged prompt through, or misreads a client's ban on AI, the breach lands on the firm and its client.
Practice Systems Integration Depth
How deeply the product reaches into the systems legal work already lives in: document management such as iManage and NetDocuments, Word and Outlook, contract lifecycle management, matter management, e-billing, and court filing systems.
Firm systems are named and none of the connections is documented. Alexandria is described as an MCP gateway connecting Intapp, iManage, Aderant and Microsoft 365 into one layer for AI agents, used for conflicts clearing, intake and matter setup, with every agent acting under a real identity and each tool call checked against it. Charter runs as a browser extension and desktop agent across whatever AI tools a firm uses, with Claude and Harvey shown in the product imagery, and client guidelines are uploaded as PDF or DOCX files.
Nothing describes what each connection reads, in which direction or what a firm must configure. No integrations page or developer documentation for either product is published; the vendor's documentation site covers only an earlier hallucination detection SDK called Gateway.
Deployment Model and Data Residency
Where the software runs and where the data sits. Multi tenant cloud, single tenant, private deployment, on premises, and whether region of residence is a published option or an enterprise conversation.
Truth Systems' home page lists deployment on premises, single tenant architecture and geolocation control, so the tenancy model is stated. It names no hosting provider or region, does not say which regions geolocation control covers, and does not say where prompts are processed when Charter evaluates them, as distinct from where captured sessions are stored.
Security Certifications and Trust Center
Independent attestation a buyer can pull without a sales call: SOC 2, ISO 27001, penetration test summaries, a trust center with current reports and named scope rather than a badge image.
No independent security attestation is published. The home page describes a robust security program and lists access features, but names no SOC 2 report, ISO certification, penetration test or trust center, for a product that captures every AI prompt and response in a law firm.
Model Supply Chain Disclosure
Which models sit underneath, whose they are, where they run, and whether the vendor commits to telling customers when that changes. A legal buyer inherits every dependency it cannot see.
A compliance AI agent is referred to without saying what runs underneath it. In October 2025 cofounder Nam Nguyen said the product uses a blend of smaller language models and large language models, and that the company wants smaller, more predictable models rewarded for spotting contradictions. No model, model provider or hosting arrangement for inference is named, and nothing commits to notice when that changes. Whether a lawyer's prompt is evaluated by a model, and whose, is not stated, so a firm cannot tell its clients where their most sensitive text goes when Charter checks it.
Commercial Transparency
Whether a buyer can learn what this costs without entering a sales process: published rates, the unit being charged, what sits behind an enterprise tier, and what implementation adds.
No pricing is published at any level: no price, no tier and no unit of charge. The route to a price is a demo request.
Firm and Practice Coverage
Who the product is actually built for. AmLaw, midlaw, small firm and solo, in house departments, government and courts, and which practice areas are supported rather than merely claimed.
The site addresses law firms throughout, the named customer is a law firm, and cofounder Nam Nguyen has said the company mainly targets the AmLaw 200; its Y Combinator profile also names banks, financial services and other regulated industries, and lists a team of six. Charter covers human use of AI across tools and Alexandria covers AI agents, with reporting by client and matter. Not stated: which browsers, desktop systems and AI tools Charter supports, whether Alexandria is generally available, and what firm size the product is built for.

Legal Signals
What each signal meansA signal records what public sources say on the date shown. It is not a grade and it is not a recommendation. Where a signal reads Not addressed, it means the index did not locate the material in public sources on that date, which is a statement about disclosure rather than about the product.
Client Data in Training
Can material a lawyer puts into this product be used to train a model?
No customer agreement, terms of service or equivalent contract is published on any surface located, and no policy page states a position on training. Nothing is granted and nothing is withheld, so a client has no term to hold the firm to. Where a policy page does state a position, the row takes the matching policy value instead and the summary records that no agreement exists.
No customer agreement, terms of service or policy page is published, and nothing published states whether captured prompts or client guidelines are used to train any model. Nothing is granted and nothing is withheld, so a firm has no term to point to when a client asks.
Prompt and Output Retention
How long does the product keep what a lawyer typed, and can that be set to zero?
The customer controls the retention window, by product configuration or by contractual instruction, but zero retention is not stated as available.
The firm sets retention. The home page offers custom data retention policies and data lifecycle management to meet retention requirements, so the firm decides how long captured sessions are kept. No default period is stated, zero retention is not mentioned, and nothing says how long the vendor or any model provider keeps a prompt it evaluates.
Ethical Walls and Matter Segregation
Does retrieval respect the firm’s ethical walls, or can the model read across them?
Segregation is asserted in public materials with no published detail on how it is enforced.
Truth Systems says outside counsel guidelines, ethical walls and matter scope are mapped to every prompt and agent action before execution. Every Alexandria agent acts under a real identity with each tool call checked against it, and walls are said to hold for agents as they do for attorneys. The mechanism is not published. Alexandria is said to connect Intapp and iManage, where firms keep walls and document permissions, but nothing explains whether it reads those permissions at the time of each action or keeps its own copy the firm must maintain.
Third Party Request and Subpoena Notice
If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?
No located term or policy addresses third party requests for customer data.
No term or policy addresses what happens when a government, court or other third party demands the prompts and responses Charter captures. No terms of service or privacy policy is published.
Primary Law Corpus Provenance
Where does the law in this product come from, and does the vendor have the right to use it?
Sources are identified without stating the license or rights basis.
The rules come from documents the firm supplies. Truth Systems says Charter reads a firm's own policies and each client's outside counsel guidelines as written, uploaded as PDF or DOCX files, and turns each mandate into access controls, and Alexandria draws context from the firm's own systems. No external legal corpus sits behind the product, so no licensing question arises. What is not stated is how the rules stay in step when a client revises its guidelines.
Good Law Verification
Does the product tell you when the authority it just cited has been overruled?
No located public material addresses whether authority is checked for subsequent history.
The product cites no case law or statutes, and no published material addresses subsequent history. Its output is a decision to allow, warn or block a prompt, not a statement of law.
Refusal and Uncertainty Behavior
What does the product do when the answer is not in the corpus?
No located public material addresses what the product does when it cannot ground an answer.
Nothing describes what the agent does when it cannot tell whether a prompt breaks a rule, or when a client guideline is ambiguous: whether it blocks, allows, warns or refers the question to a person.
Fabricated Citation Record
Does a public court record exist addressing fabricated or hallucinated legal citations in output from this product?
No court order, opinion or disciplinary record addressing fabricated or hallucinated legal citations produced by this product has been located as of the date shown. This is a statement about the public record on that one subject, not a finding about the product, and this signal is not a litigation history.
The AI Hallucination Cases database maintained by Damien Charlotin records no case naming Truth Systems; its one record matching Charter concerns a party named The Academy Charter School and does not involve the product. No court order, opinion or disciplinary record addresses fabricated or hallucinated citations produced by Truth Systems or Charter, and the product does not generate legal citations. This is a statement about the public record rather than a finding about the product.
Bar Guidance Alignment
Has the vendor engaged in public with the ethics opinions its buyers are bound by?
Public materials refer to professional responsibility in general terms without naming guidance.
Truth Systems says its agents uphold attorneys' obligations and keep ethical walls and client confidentiality in place. No ethics opinion is named, including ABA Formal Opinion 512 on generative AI, although supervising how lawyers use AI tools is what the product is sold to support.
Billing and Fee Posture
Does the vendor address what happens to the bill when the work takes an hour instead of six?
A usable record of AI assisted work exists with no published fee guidance.
Charter logs each session by matter, and its reporting shows AI use and time by client and matter; a named customer says clients want to know which tool was used on their matters, what it did and how much time it saved. Nothing published addresses how a firm should reflect AI assisted work on a bill or disclose it to a client.
Outside Counsel Guideline Readiness
Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?
No located public material supports a client side disclosure obligation.
No subprocessor or model provider list is published, and no security or disclosure material is offered on the site. A firm whose client asks which third parties see the prompts Charter captures could not answer from anything published.
Court Disclosure Support
If a judge’s standing order requires an AI disclosure, can the product produce one?
Some elements of the record are available, short of a document level export.
Charter records the tool, prompt, response and matter for each session and shows every AI interaction across the firm on one dashboard. Nothing says the record can be exported per document, captures whether a lawyer verified the output, or answers a court's AI disclosure order, and no template or guidance is published.
