Section 4 — Renewal. Tenant may renew this lease for one additional 12-month term by giving written notice at least 60 days before the current term ends. Rent during the renewal term will not increase by more than 3%. Either party may end this agreement with 60 days' written notice, without penalty.
Live
A trust layer for documents, code, software, and AI Agent work.
Pactlyst.ai helps AI agents and apps check work before anyone commits — documents, code, software, and AI Agent work — turning dense terms and risky output into clear signals, a verdict, and signed proof.

TRY IT — SIMULATED
See a Pactlyst Score in action.
Pick a sample — a clause, code, or a software change — or paste your own clause to see the kind of signal the engine produces.
Pactlyst Score
Low risk
Balanced and readable — clear notice windows, capped costs, no surprises.
This is a simulated preview — pasted text isn't really analyzed. The live scoring API is available now — request an API key below to start.
WHY THIS EXISTS
AI agents are about to sign contracts on your behalf.
Who checks their work?
Agents already book, buy, and click 'I agree' for us — without reading a word. Every term they accept is a commitment you didn't review. Pactlyst.ai is the trust layer that checks the work before anyone — human or machine — commits: the fine print, the code, the finished output.
01 / THE PLATFORM
One engine.
One engine.
Every kind of work.
Every check — document, code, or software — one engine, plain language, live today.
Scan API
Send a document from your product and get back a structured review — a Pactlyst Score, key terms, and the risks to examine — checked against 1,000 document playbooks from a 3,000-playbook library that also covers code and software.

Pactlyst Score
One consistent signal for any work — a document, code, or a software change — that says whether it is Low risk, Needs review, or High risk, explained in plain language instead of jargon.
Live · built to travel across products
Commitment monitoring
Track what reviewed work commits you to: contract renewals and notice windows, payment and delivery dates, software release deadlines, support and update windows, and other obligations that are easy to miss after approval.
Live · ongoing checks
Verdict Gates
A score becomes a hold. Low risk proceeds; Needs review needs an acknowledgment that shows the actual findings; High risk waits for a named human approver. Approvals expire — a lapsed approval can never release a signature, and the lapse is written into the record.
Live · policy on every check
Vouchi — the audit agent
Vouchi is Pactlyst.ai’s autonomous audit agent. When a work check carries the ask, Vouchi grades the work against it line by line, questions the agent that did the work on the weak, missing, or contrary lines, and scores only what can be checked. 90 or higher passes. Below 90, Vouchi orders a redo naming the exact gaps — up to 3 rounds — then hands the work to a human at the Verdict Gate. Vouchi never approves anything.

IN THE SAME API
Four capabilities, live in the same API.
These extend the same checks to AI assistants, proof records, your own product's pages, and a clear view of every check you run.
AI assistant connection (MCP)
AI assistants connect to Pactlyst over MCP — score a document, check finished work, and verify a PactCheck Receipt™, right from the assistant. Three tools at version 1.2.0, listed on the Official MCP Registry.
PactCheck Receipt™
A signed, timestamped PactCheck Receipt™ showing what was checked — a document, code, or software work. Bundle a period's receipts into PactCheck Evidence™ packs, or a signed PactCheck Record™ an auditor can verify offline.
Pactlyst Embed & Alerts
Put the check inside your own product with a paste-in widget, and get a signed webhook the moment a check completes or a gate moves. Your key never reaches the browser — sessions are short-lived and scope-locked.
Live · webhooks on Pro & Enterprise
Pactlyst Insights
Your check volume, verdict mix, gate outcomes, and outcome metrics — approval turnaround, material exceptions caught, agreements passed without a human touch — in plain language. Operational numbers only; never an accuracy claim.
Live · your key's own numbers
PACTCHECK VERIFIED™
The mark that a review really happened.
PactCheck Verified™ is the badge a product shows next to a document that carries a real PactCheck Receipt™. It is earned by an actual review — never bought, never decorative — and anyone who sees it can verify the receipt behind it: what was reviewed, when, and that the record has not been altered.

03 / WHO IT’S FOR
Built to meet agreements where they happen.
These are use cases for teams adding clearer document decisions to products people already trust.
Real estate platforms
Help renters and property teams scan leases for renewal terms, fees, notice windows, and other commitments.
HR tools
Check offer letters for compensation details, restrictions, deadlines, and terms a candidate should understand.
AI assistants
Give an assistant structured context when someone asks, “Is this safe to sign?”—with clear signals and reasons.
Lenders
Review agreements for obligations, unusual clauses, and risk signals that deserve closer human attention.
Software should explain the deal, not just move the file.
Plain language first. The useful answer is the one a person can understand and act on.
Pactlyst.ai is built to be called by machines: we build the system; developers connect it to the products people already use.
Pay per review. Verification stays free.
The party that runs the review pays per check. One check is one check — a document, code, or software work, drawn from the same pool. Verification is free to everyone, forever — so the receipt can spread to every party that relies on it.

04 / API ACCESS
Get your API key.
Self-serve and instant — free tier, 5 checks a month. Your key appears once on screen and is emailed to you. Tell us what you’d build — it helps shape what comes first.
Revoke a key
Key compromised, or issued to the wrong email? Revoke it here — it stops working immediately, everywhere it was used, and any assistant connected through it is disconnected. Then request a new one above.
Lost your key? Get a revoke link by email. Opening the link revokes every key issued to that address — no need to paste a key you no longer have.
