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.
Coming soon
A trust layer for documents.
Pactlyst.ai will help AI agents and apps check agreements for people—turning dense terms into clear signals before someone commits.

TRY IT — SIMULATED
See a Pactlyst Score in action.
Pick a sample clause — or paste your own — to see the kind of signal the engine will produce.
Looks fair
Balanced and readable — clear notice windows, capped costs, no surprises.
This is a simulated preview — pasted text isn't really analyzed. The live scoring engine is in development. Request an API key below to be first in line.
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 reads the fine print before anyone — human or machine — commits.
01 / WHAT’S COMING
One document engine.
One document engine.
Built to do more.
We plan to build the same plain-English thinking behind the Pactlyst app into tools other products can use.
Scan API
Send an agreement from your product and get back a structured review with a Pactlyst Score, key terms, and risks to examine.
Planned interface · not yet available
Pactlyst Score
A consistent signal that helps products explain whether an agreement looks fair, risky, or worth a closer look—without burying people in legal language.
Planned · built to travel across products
Commitment monitoring
Help people remember what they agreed to: renewals, notice windows, payment dates, and other obligations that are easy to miss after signing.
Planned for ongoing checks
Negotiation agents
Future tools that can spot terms worth changing, explain the tradeoffs, and help a person prepare a clear response—while keeping them in control.
Longer-term planned direction
ALSO PLANNED
Four more capabilities on the roadmap.
These ideas extend the same document checks to AI assistants, proof records, company-specific rules, and large collections of agreements.
AI assistant connection (MCP)
A planned connection that will let AI assistants ask Pactlyst to check a document when someone needs help understanding it.
Coming soon · not yet available
Proof-of-scan receipts
A signed, timestamped record showing that a document was checked, so teams can keep clear proof for reviews and due diligence.
Planned capability · not yet available
Custom company playbooks
Companies will be able to set their own clause rules, then have every planned API review check documents against those policies.
Planned capability · not yet available
Batch and portfolio scanning
Scan a whole data room or document collection at once and get a clear map of where the biggest risks need attention.
Coming soon · not yet available

03 / WHO IT’S FOR
Built to meet agreements where they happen.
These are planned use cases for teams that want to add 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 English first. The useful answer is the one a person can understand and act on.
Pactlyst.ai is the machine-facing half of that idea: we build the system; developers connect it to the products people already use.
