A long-context reviewer that sits beside the existing system, reads what it already produces, and closes proposal writing. Aimed at legal ops teams, surfacing the exposure nobody has priced.
In short: Automated Proposal Builder for Legal is a long-context reviewer aimed at legal ops managers, covering proposal writing. It scores 75/100 on AltF Ideas, carried by demand (90) and held back by feasibility (25). Typical pricing is $4.1k–$87k per customer per year, with a first version reachable in six to twelve months for $30k–$67k.
Legal teams lose proposals rebuilt from scratch that are 80% identical. Every legal team solves this the same way: someone stays late. The error rate is tolerated because measuring it would cost more than the errors.
Proposal writing handled by a long-context reviewer, 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.

| Who | The gap |

| A generalist AI tool | No domain grounding, so output needs full human review |
| An internal hire | Works until volume doubles, then breaks again |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
The incumbent is a person, and displacing a person is a change-management problem.
