A retrieval engine that sits beside the existing system, reads what it already produces, and closes document review. Aimed at legal partners, built for one person, not a department.
In short: Document Reviewer for Legal, Run by Retrieval is a retrieval engine aimed at legal partners, covering document review. It scores 72/100 on AltF Ideas, carried by timing (93) and held back by monetisation (51). Typical pricing is $2.6k–$53k per customer per year, with a first version reachable in about a quarter for $14k–$36k.
Legal teams lose a 900-page document read by someone billing $300 an hour. It is the kind of task that is too small to fund and too costly to ignore. The cost is invisible on any P&L line, which is why it never gets fixed.
Point a retrieval engine at document review, and let people review output instead of producing it. Revenue is usage-based, which suits a buyer who wants the cost to track the value rather than the seat count.

Retrieval over private documents became cheap enough to run per query. Legal is growing at roughly 12% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
| A spreadsheet | The real incumbent in most of the market, and it is free |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
Every customer wants their own edge cases encoded, so onboarding cost is the real constraint.
