Colibri Legal
Colibri Legal is the deposition and court reporting product of Colibri.ai, the trading name of Alterra.ai, Inc., whose flagship is Sales Copilot and which also sells an AI note taker. Attorneys and paralegals start recording any remote proceeding with a click, including one run by the other side, since the app captures audio and video from the user's own computer. A real time transcript follows in a Zoom side panel with speakers identified, or in the web app, and can be streamed as live captions to colleagues who are not in the deposition.
Users highlight moments, add short notes and preload deposition questions, which Colibri displays and marks off as they are asked. AI rough drafts are ready at once. Professional legal transcriptionists produce certified final transcripts within 24 hours when ordered, whether months later or never, and a certified deposition reporter can be booked through a national court reporting firm. Transcripts sit in a cloud library with full text lookup by participant, case name, case number or any spoken word, synchronized with the audio and video.
The legal product is sold by monthly subscription, with finals charged per page and reporter appearances extra, all quoted. Colibri is English only.

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.
Speech recognition is the product. Colibri Legal is bought for the real time transcript and the AI rough draft that is ready the moment a proceeding ends, and the library, highlights, notes and question list are built around that text. The legal page calls the engine proprietary AI. Certified finals are a human service on top, ordered only when a case needs one. The same platform runs Colibri's other products, where the paid plans of its note taker add AI meeting summaries, key point extraction, suggested next steps, automatic chapters and AI refined transcripts.
None of those generative features is described on the legal page, so the legal product's AI is transcription and speaker identification.
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.
The legal page leads on machine transcription accuracy and gives no error rate or method behind the claim. Accuracy is managed by design instead. Every word in the library is tied to the audio and video, and a click anywhere in the transcript starts playback at that moment, so a user can hear what was said. The transcription product adds a custom vocabulary for names and terms, speaker identification and an online editor for correcting mistakes against the audio.
Where accuracy matters, the customer orders a final transcript from professional legal transcriptionists. Rough drafts and finals are kept apart. Nothing says how a rough draft marks words the engine could not make out. The product transcribes testimony and cites no legal authority.
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.
Machine output and the certified record are kept apart. AI rough drafts are for review during the deposition and at breaks, while final transcripts are prepared by professional legal transcriptionists, and only when the customer orders them. During the proceeding the attorney steers what is kept: highlights with a click, short notes, and a preloaded list of questions that the app marks off as each one is asked. A certified court reporter can be brought in when the record needs one.
Nothing states that a rough draft may not be quoted or filed, and no review step is described before a rough draft reaches the user. The app records with a click, including proceedings run by the other side.
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.
No law firm customer, deployment or measured result is published for Colibri Legal. The home page quotes Peter Hellman of DepoCall, a court reporting firm. Other quotes come from users of the general product: Mike Wittenstein of Storyminers on documenting client and team calls, Dr. Dimitrios Rovas of University College London on live captions for international students, and Radek Jezbera of Black Pine Executive Consulting on the Zoom integration.
Colibri states it was a Zoom Apps launch partner. Its team, spread across eight locations, comes from Google, Nuance and academia. The chief executive, Sergei Burkov, and the chief technology officer, Max Ushakov, both worked at Google, and Burkov sold an earlier startup to Google. No figure ties the legal product to time or cost saved at a named firm.
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.
Nothing on the legal page, the terms or the privacy policy addresses confidentiality or privilege for recorded proceedings and transcripts. The terms of service, last updated 14 February 2020, cover the website, mobile apps and messenger bots and do not mention depositions, transcripts or client material. The privacy policy, effective 25 April 2021, treats the content of meetings and calls as personal data and lists the outside services that process it.
Google ASR, for speech to text, and the OpenAI API are both described as handling any data in a user's online meetings and phone conversations. The policy reserves the use of collected information to personalize and improve the services. No confidentiality commitment, access restriction or deletion schedule specific to legal recordings 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 addresses lawyers' duties when relying on an AI rough draft, or the standing of a rough draft against a certified transcript. Recording consent rules go unmentioned, as does the use of a recording made of a proceeding run by the other side. The legal page markets that last use directly: a firm need not buy transcripts or recordings from the opposing party's court reporter, because Colibri can record and transcribe the proceeding itself. No advice line, competence statement or ethics reference appears in the terms or the privacy policy.
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 AI governance position, accountable owner, testing before release or evaluation result is published. Nothing addresses how transcription accuracy varies across accents, dialects, audio quality or the overlapping speech common in depositions, and Colibri's Zoom listing states the product works in English only. The privacy policy names two outside AI services, Google ASR and the OpenAI API, without saying which product uses which or how they are chosen. The about page describes the team's background in speech and language research but no review of model behavior.
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.
The privacy policy is the main stewardship document. It lists each outside processor with the data it handles and where it processes it. Amazon Web Services hosts the service in the United States, and Google ASR and the OpenAI API handle meeting and call content. Support, messaging, payment and sales run through tools including Zendesk, Twilio, Square, Mailchimp, Typeform, Apollo and Pipedrive, some of them in Spain and Estonia.
A user deletes an account by email, after which personal information is made irrecoverable. The policy still refers to the EU Privacy Shield. Nothing describes security controls, encryption, access logging, retention periods for recordings or breach notification. On the general app, audio is kept without limit on every plan, and video for two months on the free plan and two years on paid plans.
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.
The terms of service, last updated 14 February 2020, provide the service as is, disclaim warranties and cap Colibri's liability at the total amounts the user has paid. California law governs, and disputes go to binding arbitration. No indemnity runs to the customer, and no term addresses a transcript that proves wrong, a missed recording or a lost file. Certified final transcripts and court reporter appearances are bought on separate quotes whose terms are not published, and the terms make no mention of either.
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.
The product works where remote proceedings happen. The Colibri App for Zoom shows live transcription with identified speakers in a side panel, installed from the Zoom App Marketplace, and Colibri was a Zoom Apps launch partner. The cloud app also records audio and video from any online meeting platform and from the telephone, and can capture a proceeding from the user's own computer. Transcripts export to Microsoft Word, PDF, VTT and other formats.
The general app connects to Slack and Salesforce and lists an API among its plan features. No connection to a case management, document management or litigation support system is offered.
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.
The service runs in the cloud with nothing to install. The privacy policy names Amazon Web Services as host, with processing in the United States. The OpenAI API and most other services are also processed in the United States, with some sales and support tools in Spain and Estonia. No region choice, single tenant option or private deployment is offered, and where Google ASR processes audio is not stated.
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 security certification, audit report or trust center is offered, and the legal page makes no security claim. The privacy policy describes how personal information is used and shared but names no security control or standard.
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.
Two outside AI services are named in the privacy policy, without saying which product uses them. The legal page calls its rough drafts the work of proprietary AI, and the about page describes a real time speech recognition platform built by a team from Google and Nuance. The privacy policy lists Google ASR as an automatic speech recognition engine and the OpenAI API, in the United States, as processors of any data in a user's meetings and calls.
The general app lists a custom language model among its plan features. Which engine produces a Colibri Legal rough draft, and whether customers hear of a change, is not stated.
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.
The legal product's price structure is published without figures. A low monthly subscription covers all real time transcription and rough drafts, final transcripts by professional legal transcriptionists are charged by the page, and appearance fees apply when a certified court reporter is booked. All three are quoted on request. Colibri's general note taker does publish prices. Its free plan includes five hours of transcription a month.
Starter costs $16 a user a month billed annually, or $20 monthly, with 20 hours, and Pro costs $40 or $50 with unlimited transcripts. Enterprise plans are custom. The legal page does not say whether a legal subscription maps to those plans.
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 legal edition is pitched to attorneys and paralegals, and through its court reporting partner to proceedings that need a certified record. The legal page names depositions, court hearings, meet and confer sessions, mock trials and internal meetings, on any online platform or the telephone. It works with or without a court reporter, and on proceedings run by either side. The product is English only. No jurisdiction, practice area or firm size is named, and the court reporting partner is not identified.

No published figure
- Colibri does not publish a price for its legal product.
- The legal product has three charges: a low monthly subscription, a per page fee for final transcripts, and an appearance fee when a certified court reporter is booked.
- All three are quoted on request.
- Colibri's general note taker does list prices: free for 5 hours a month, then $16 to $50 per user per month.
- Nothing says whether a legal subscription matches those plans.
Colibri's legal product is priced in three parts. A low monthly subscription covers all real time transcription and rough drafts. Final transcripts by professional legal transcriptionists are charged by the page. Appearance fees apply when a certified court reporter is booked. No figure is published for any of the three, and each is quoted on request.
Colibri's general note taker has a public price list. The Free plan is $0 and includes 5 hours of transcription a month. Starter is $20 per user a month on monthly billing or $16 on yearly billing, with 20 hours of transcription a month and a 30 day free trial. Pro is $50 per user a month on monthly billing or $40 on yearly billing. Enterprise plans are custom. Nothing says whether a legal subscription maps to those plans, so no figure is shown as the entry price for the legal product.
Implementation: Not stated.
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?
A published agreement or policy exists and none of it addresses the question either way, or the document that would answer it could not be read and the summary names the retrieval limit. The summary states which shape the silence takes: an improvement right granted that never names training, or no improvement right granted at all.
Neither the terms of service nor the privacy policy says whether recordings or transcripts train a model, Colibri's or a provider's. Colibri's privacy policy reserves the use of collected information to personalize and improve the services, without naming training. It lists Google ASR and the OpenAI API as processors of the content of a user's meetings and calls. The legal page makes no statement on training.
Prompt and Output Retention
How long does the product keep what a lawyer typed, and can that be set to zero?
Retention is acknowledged in public materials with no stated period.
Personal information is kept as long as law or regulation requires, according to the privacy policy, and made irrecoverable when an account is deleted, which a user requests by email. The general app keeps audio without limit on every plan, and video for two months on the free plan and two years on paid plans. No retention period is stated for legal recordings, rough drafts or certified transcripts.
Ethical Walls and Matter Segregation
Does retrieval respect the firm’s ethical walls, or can the model read across them?
No located public material addresses walls or matter level segregation.
Paid plans carry a team library of calls, free viewer accounts and a shared team workspace. Nothing describes separating matters, restricting a user to certain cases, or limiting who may view the recording of a particular proceeding.
Third Party Request and Subpoena Notice
If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?
Published terms or policy address disclosure to authorities or in response to legal process, and no commitment or reservation regarding customer notice is located anywhere. The vendor has told the customer that data can leave and has said nothing about whether the customer hears of it.
The privacy policy allows disclosure of information to satisfy applicable law, legal process or a governmental request. Nothing commits Colibri to tell the customer that a demand has arrived or to resist it, and nothing addresses requests for recordings of legal proceedings in particular.
Primary Law Corpus Provenance
Where does the law in this product come from, and does the vendor have the right to use it?
No located public material identifies the corpus behind the product’s answers.
The product transcribes the customer's own recordings of proceedings. No body of law, licensed content or outside data source sits behind the output.
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 produces transcripts and cites no legal authority, so a check of later history does not arise and none is described.
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 how a rough draft marks speech the engine could not make out, a low confidence word, crosstalk or an unidentified speaker. The remedy offered is human: a certified final transcript from professional legal transcriptionists, or correction in the editor against the synchronized audio.
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, which records court decisions worldwide that address hallucinated AI content and the tool involved where known, has no entry naming Colibri, Colibri Legal or Alterra.ai. Colibri produces transcripts of proceedings, not filings or citations to legal authority.
Bar Guidance Alignment
Has the vendor engaged in public with the ethics opinions its buyers are bound by?
No located public material engages with bar or ethics guidance.
No page engages with lawyers' professional obligations, recording consent rules or any ethics opinion. The legal page invites firms to record proceedings run by the other side instead of buying the transcript from that side's reporter. It says nothing about the rules that govern recording a proceeding or relying on a rough draft.
Billing and Fee Posture
Does the vendor address what happens to the bill when the work takes an hour instead of six?
Public materials claim time savings without addressing billing or disclosure, and the product sits inside a fee relationship between a lawyer and a client where those savings would change the bill.
Colibri's legal page pitches cost control to attorneys and paralegals. A firm pays for a certified final only if a case needs one, whether months later or never. It can also record and transcribe a proceeding instead of buying transcripts or recordings from the other side's court reporter. Nothing addresses how transcript costs are passed to clients or shown on a bill.
Outside Counsel Guideline Readiness
Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?
A current subprocessor or model provider list is published.
The privacy policy lists each outside processor, what it handles and where: Amazon Web Services for hosting, Google ASR and the OpenAI API for meeting and call content, and support, payment, messaging and sales tools. It does not say which of them a Colibri Legal recording passes through. No client facing disclosure material, security summary or AI terms are published.
Court Disclosure Support
If a judge’s standing order requires an AI disclosure, can the product produce one?
No located public material addresses court disclosure or verification certification.
A rough draft is labeled as such and kept apart from a certified final, and every transcript stays tied to its recording. Nothing records which engine produced a rough draft, no export of AI use is described, and nothing addresses disclosure of AI transcription in material put before a court.
