Point a retrieval engine at document review, and let people review output instead of producing it. Aimed at construction project managers, closing the loop while everyone is asleep.
In short: Document Reviewer for Construction, Run by Retrieval is a retrieval engine aimed at construction project managers, covering document review. It scores 79/100 on AltF Ideas, carried by moat (89) and held back by feasibility (70). Typical pricing is $5.1k–$108k per customer per year, with a first version reachable in about a quarter for $13k–$38k.
Construction teams lose a 900-page document read by someone billing $300 an hour. Every construction team solves this the same way: someone stays late. Most operators assume this is simply the cost of doing business.
Document review handled by a retrieval engine, with a human signing rather than writing. 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 |
|---|---|
| A generalist AI tool | No domain grounding, so output needs full human review |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
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.
→ AltF IdeaLabAsk how they handle this today and what it costs them. If nobody can quantify the pain, the demand score is optimistic.
