A retrieval engine that handles document review end to end and hands a human the exceptions rather than the queue. Aimed at legal paralegal teams, closing the loop while everyone is asleep.
In short: Retrieval Document Reviewer for Legal is a retrieval engine aimed at legal paralegal leads, covering document review. It scores 70/100 on AltF Ideas, carried by timing (86) and held back by feasibility (40). Typical pricing is $4.6k–$69k per customer per year, with a first version reachable in six to twelve months for $38k–$116k.
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. Whoever knows how it works becomes a single point of failure.
Point a retrieval engine at document review, and let people review output instead of producing it. Revenue is data subscription, 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 |
|---|---|
| A spreadsheet | The real incumbent in most of the market, and it is free |
| A generalist AI tool | No domain grounding, so output needs full human review |
| An internal hire | Works until volume doubles, then breaks again |
