Point a retrieval engine at document review, and let people review output instead of producing it. Aimed at construction ops teams, built for one person, not a department.
In short: Construction Document Reviewer is a retrieval engine aimed at construction ops managers, covering document review. It scores 83/100 on AltF Ideas, carried by demand (95) and held back by feasibility (42). Typical pricing is $4.0k–$86k per customer per year, with a first version reachable in six to twelve months for $44k–$119k.
Construction 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 per-outcome, 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. Construction is growing at roughly 20% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| An internal hire | Works until volume doubles, then breaks again |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
The buying cycle is slower than the build, so runway assumptions matter more than code.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
Score problem urgency, willingness to pay, and reachable audience size before writing any code.
