Who writes this
Pallav Rai is the founder of PactSage and built its clause-extraction pipeline — the classifier, the clause taxonomy for each type of agreement, the span verification that re-locates every quoted clause in the source document, and the obligation tracker that alerts on the action-by date. He is not a lawyer, and PactSage is not a substitute for one.
The guides on this site are written from that work rather than from general research. When a guide says the extraction reports absent clauses, or that a quote is re-located in your source document and flagged when it cannot be, those are descriptions of code that exists and can be read.
Why it works this way
Every claim PactSage makes about a document points at the sentence it came from. That single constraint shaped the whole product: a finding whose quote cannot be found again in your file is shown with a warning rather than quietly dropped, and a document that does not match a supported contract type is refused rather than forced through the wrong taxonomy.
The same rule governs what is written here. There are no customer counts, no testimonials and no logo wall on this site, because none of those exist yet. The numbers that do appear — eight supported contract types, forty-three clause types, four risk levels, the 0.85 precision floor the extraction eval fails the build below — are all things the system can be read for.
If you want the longer version of how a document is actually read, that is on the contract review page, and the worked example on a document most people have signed is the rent agreement checklist.
What PactSage is not
It is not a law firm, it does not give legal advice, and nobody writing for it is presenting themselves as a lawyer. It reads what is in front of it and shows you the text. Deciding what to do about a clause — and certainly deciding whether to sign — is a judgement for you, and for a qualified lawyer where the stakes justify one.
