PromiseProof
Every promise a company makes, quoted word for word
Paste any company's pricing page. PromiseProof pulls out every consequential promise — guarantees, performance figures, superlatives, breadth claims — quoted word for word, and flags which ones a careful buyer would want evidence for. It never calls a company dishonest. It says what was promised, in their words, before you're six months into a contract arguing about it. Free, no account, no email. Deterministic, not an LLM — if the wording isn't on the page, it isn't in your result.
Maker here.
I built this because the promises on a sales page are the ones you'll want to hold a vendor to later, and they're exactly what nobody writes down before signing.
It's deterministic, not an LLM — claims are extracted verbatim. If the wording isn't on the page, it isn't in your result. I didn't want a tool that could invent a claim about someone else's company.
Two things I'd genuinely like feedback on: where the extraction is wrong, and whether the free tier is useful on its own.
Disclosed: there's a paid tier that unlocks the rest. The free result stays the whole answer for the top two.
