The fine print, in plain English first.
This document is published for transparency while it is being finalized with our outside counsel. Material substantive changes before the version-1 effective date will be summarized at the top of this page and emailed to all paying firm admins. Until then, treat this as Sentinel’s good-faith statement of how the service works; final binding language will be the executed EULA delivered with your subscription.
Last updated: 2026-05-09. Operated by A.I. Esquire, LLC (“Sentinel,” “we,” “us”), a Connecticut limited liability company. Hartford, Connecticut, USA.
1. The plain-English summary
Sentinel is a defensive AI-posture layer for lawyers. You pay us a monthly subscription. In exchange, our extension, desktop app, and API watch what you paste into AI tools, verify your citations against real case law, build cryptographic audit trails, and produce reports a court will accept. We never train on your data, never sell it, and the firm can delete it whenever they want.
The legal sections below exist because attorneys are our customer base and you would notice if they were missing. We tried to keep them honest.
2. Acceptance
By creating a Sentinel account, installing the Sentinel browser extension, installing the Sentinel desktop app, or accessing the Sentinel API, you (the “Subscriber”) agree to be bound by this Agreement. If you accept on behalf of a firm, you represent that you have authority to bind that firm.
3. License
Subject to your payment of the applicable subscription fees and your compliance with this Agreement, Sentinel grants you a limited, non-exclusive, non-transferable, non-sublicensable license to install and use the Sentinel software (including the extension, desktop app, and API) for your firm’s internal law-practice use during the subscription term.
4. Restrictions
You agree not to:
- reverse-engineer, decompile, or attempt to derive source code, except to the extent applicable law expressly permits;
- resell, sublicense, white-label, or expose the Sentinel API as a substitute service to third parties without a written reseller agreement;
- use Sentinel to build a directly competing product, or to train any machine-learning model on Sentinel outputs;
- disable, bypass, or override safety classifications, citation verifications, or audit-log entries; or
- use Sentinel for any unlawful purpose or to violate any applicable bar rule, court order, or court rule.
5. Subscriptions, fees, and trials
Subscriptions are billed monthly in advance through Stripe. The first 14 days of a paid subscription are a free trial; you may cancel during the trial without charge. After the trial, non-payment results in suspension of access. Subscription fees, tiers, and limits are described on the public pricing page and may change with at least 30 days’ written notice (continued use after the notice period constitutes acceptance).
All fees are non-refundable except as required by applicable law or as expressly provided in §14 (Citation-Verification Service Credit) and §16 (30-Day Money-Back).
6. Term and termination
This Agreement takes effect on first use and continues until terminated. Either party may terminate for convenience on 30 days’ written notice; Sentinel may terminate immediately for material breach (including non-payment) on written notice with opportunity to cure.
On termination, your access ends, and Sentinel hard-deletes firm data after a 30-day grace period during which the firm admin may export the audit log. Sections that by their nature should survive (intellectual property, confidentiality, indemnity, limitation of liability, governing law, the §14 service credit for any sanction order issued during the subscription term) will survive termination.
7. Privacy and data handling
Sentinel’s collection and use of personal information is governed by our Privacy Policy, which is incorporated into this Agreement by reference. In the event of conflict, the Privacy Policy governs personal-information handling and this Agreement governs everything else.
Sentinel does not train any AI model on your content. Sentinel does not transmit raw paste contents to its servers in default mode; Layer-1 classification runs locally in your browser or desktop, and only redacted text and classification metadata are forwarded.
8. AI-output disclaimer
Sentinel orchestrates outputs from multiple AI providers (currently Anthropic Claude, under HIPAA BAA). AI-generated content can be wrong, incomplete, or misleading. You are responsible for independently verifying any AI-generated content before relying on it in legal practice. Sentinel’s citation verifier reduces the probability of fictitious citations reaching a filing, but no automated system can guarantee that a verified citation states the proposition you intend; you remain responsible for legal substance.
Nothing in Sentinel constitutes legal advice. Sentinel is a software product and not a law firm. Use of Sentinel does not create an attorney-client relationship between you and Sentinel or its principals.
9. Intellectual property
Sentinel and its licensors retain all right, title, and interest in and to the Sentinel software, including the source code, trained classifiers, prompts, audit-chain protocol, brand assets, and all related intellectual property. You retain all right, title, and interest in your firm’s content. You grant Sentinel a limited, non-exclusive, royalty-free license to process your content solely as necessary to provide the service.
10. Confidentiality
Each party agrees to protect the other’s Confidential Information using at least the same standard of care it uses to protect its own confidential information of like kind, and in no event less than reasonable care. “Confidential Information” means information disclosed by one party to the other that is marked confidential or that a reasonable person would understand to be confidential under the circumstances, including firm content, audit logs, billing information, and Sentinel’s non-public technical architecture.
11. Warranty disclaimer
EXCEPT AS EXPRESSLY STATED IN THIS AGREEMENT, SENTINEL IS PROVIDED “AS IS” AND “AS AVAILABLE,” AND SENTINEL DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING. SENTINEL DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY DATA WILL BE PRESERVED.
12. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, SENTINEL’S TOTAL CUMULATIVE LIABILITY UNDER OR RELATING TO THIS AGREEMENT SHALL NOT EXCEED THE GREATER OF (A) THE TOTAL FEES PAID BY THE SUBSCRIBER TO SENTINEL IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) THE CREDIT AMOUNT EXPRESSLY PROVIDED IN §14. IN NO EVENT WILL SENTINEL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUES, LOST DATA, OR COST OF SUBSTITUTE SERVICES.
13. Indemnification
Sentinel will defend you against any third-party claim alleging that the Sentinel software, used in accordance with this Agreement, infringes a U.S. patent, copyright, or trademark, and will indemnify you against amounts finally awarded against you by a court or paid in a Sentinel-approved settlement.
You will defend Sentinel against any third-party claim arising from (a) your firm’s content, (b) your use of the service in violation of this Agreement, applicable law, or any bar rule, or (c) any content you upload, generate, or file through the service.
14. Citation-Verification Service Credit
This Section is the binding restatement of the “up to $5,000” promise referenced in our marketing. Read it carefully; in the event of conflict between marketing language and this Section, this Section controls.
14.1. The Service Credit
If, while you are an active paying Subscriber, all of the following conditions are satisfied, Sentinel will credit your account up to Five Thousand U.S. Dollars (USD $5,000) of Sentinel service value (the “Credit”), applied as a reduction of future subscription charges until exhausted:
- You generated, through Sentinel, a Sentinel Verification Certificate (“Certificate”) for a court filing or filed document (the “Filing”);
- On the Certificate, every citation in the Filing was marked verified (and no citation was marked hallucinated, misquoted, unknown, or overruled);
- You filed the Filing in the version corresponding to the Certificate (no post-Certificate edits adding citations);
- A court of competent jurisdiction issued a written order imposing a monetary sanction or fine against you, in your professional capacity as an attorney of record for the Filing, solely and expressly on the ground that one or more citations in the Filing was fictitious or did not exist; and
- You provided written notice to Sentinel within thirty (30) calendar days of the sanction order, accompanied by (i) a complete copy of the sanction order; (ii) the filed Filing; (iii) the Sentinel Verification Certificate; and (iv) any responsive papers from opposing counsel concerning the sanction.
14.2. Cap
The Credit is capped at USD $5,000 in aggregate per attorney per calendar year, and at USD $5,000 in aggregate per Filing, regardless of the number of citations sanctioned.
14.3. What this Service Credit is not
- Not insurance. Sentinel is not licensed as an insurer in any jurisdiction. The Credit is not a contract of insurance, indemnification of liability, surety, or guarantee of legal outcome.
- Not legal-malpractice coverage. Maintaining adequate professional-liability coverage with a licensed carrier is your sole responsibility. The Credit is not a substitute for, supplement to, or modification of that coverage.
- Not legal advice. Nothing in this Section creates an attorney-client relationship between you and Sentinel or its principals. Sentinel does not provide legal services.
14.4. Disqualifications
The Credit is unavailable, and Sentinel may decline to issue it, if:
- the sanctioned citation appeared on the Certificate as anything other than verified (including but not limited to unknown, misquoted, hallucinated, overruled, or pending);
- you added, modified, or substituted any citation in the Filing between Certificate generation and filing;
- the sanction order grounds also include any conduct other than the fictitious-citation ground (including procedural sanctions, frivolous-argument sanctions, sanctions for misquotation, sanctions for failure to disclose AI use, or sanctions for misconduct unrelated to citation accuracy);
- you are not in good standing in your bar of admission at the time of the sanction order;
- you used a non-paid, free-trial, evaluation, or unauthorized account;
- you used a Sentinel feature contrary to its documented purpose, including disabling, bypassing, or overriding the verifier’s warnings;
- the sanction was vacated, stayed, or reversed before the Credit issued (in which case the Credit will not issue, and any prior Credit will be reversed); or
- you fail to provide the documentation required by §14.1 within the notice period.
14.5. Sentinel’s investigation right
Within thirty (30) days of receiving notice under §14.1, Sentinel may request additional documentation or seek to confer with you concerning the sanction order. You agree to cooperate in good faith. Sentinel will issue or deny the Credit, in writing, within sixty (60) days of receiving all requested documentation.
14.6. No cash equivalent
The Credit applies as a reduction against future subscription charges under your then-current Sentinel plan. The Credit has no cash value, is not transferable, and is not refundable.
14.7. Exclusive remedy
Where this Section applies, the Credit is your sole and exclusive remedy for sanctions described in §14.1, and Sentinel’s aggregate liability for such sanctions is capped at the Credit amount.
15. Governing law and dispute resolution
This Agreement is governed by the laws of the State of Connecticut, without regard to its conflict-of-laws rules. Any dispute arising under or relating to this Agreement shall be resolved by binding arbitration administered by JAMS in Hartford, Connecticut, under its Streamlined Arbitration Rules. Either party may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information.
16. 30-day money-back
If you are unsatisfied within the first 30 days of your first paid subscription, email billing@aiesquire.io and we will refund the most recent monthly charge. This applies once per firm.
17. Modifications
Sentinel may update this Agreement to reflect changes in the service, applicable law, or commercial terms. Material changes are emailed to firm admins at least 30 days before they take effect; continued use after the effective date constitutes acceptance. Non-material changes (typo fixes, formatting, non-substantive clarifications) take effect on posting.
18. Severability and waiver
If any provision of this Agreement is held unenforceable, the remainder shall remain in full force and effect, and the unenforceable provision shall be reformed to the minimum extent necessary to make it enforceable. A failure to enforce any provision is not a waiver of that or any other provision.
19. Assignment
You may not assign this Agreement without Sentinel’s prior written consent. Sentinel may assign this Agreement in connection with a merger, acquisition, or sale of substantially all of its assets, provided that the successor agrees in writing to the same obligations.
20. Entire agreement
This Agreement, together with the Privacy Policy and any order forms or addenda executed between the parties, is the entire agreement between the parties concerning the subject matter, and supersedes all prior or contemporaneous communications, whether oral or written.
