A retrieval engine that sits beside the existing system, reads what it already produces, and closes document review. Aimed at legal solo practitioners, surfacing the exposure nobody has priced.
In short: Retrieval Document Reviewer for Legal is a retrieval engine aimed at legal solo practitioners, covering document review. It scores 72/100 on AltF Ideas, carried by demand (91) and held back by monetisation (26). Typical pricing is $1.2k–$23k per customer per year, with a first version reachable in about a quarter for $13k–$35k.
Legal teams lose a 900-page document read by someone billing $300 an hour. Every legal team solves this the same way: someone stays late. It scales linearly with headcount, so growth makes it worse rather than better.
Point a retrieval engine at document review, and let people review output instead of producing it. Revenue is seat saas, which suits a buyer who wants the cost to track the value rather than the seat count.

| A spreadsheet | The real incumbent in most of the market, and it is free |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
Trust has to be earned before anyone lets this run unsupervised.
