The problem
Plenty of teams have the same problem: a pile of documents nobody can search properly, and the answer buried somewhere inside them. Most of them do not want a consulting engagement. They want the thing to already exist.
Building it once for one client solves it once. Packaging it means the same work keeps paying, and a buyer can try it before ever speaking to me.
What I built
- A live public demo that answers questions against sample documents with no signup, so a buyer can judge the quality in about thirty seconds.
- Answers with citations that point back to the exact passage, plus a confidence signal, because an answer you cannot check is not worth much.
- Self serve billing through Stripe: checkout, webhook provisioning, an API key minted and emailed automatically, no human in the loop.
- Per account quotas and per visitor rate limits enforced atomically in the database, so usage cannot be exceeded under concurrency and a free public demo cannot run up an unbounded inference bill.
The hard part
The commercial plumbing, not the AI. Retrieval is a known pattern. Making a stranger's payment turn into a working API key with no human involved, and making sure a free public demo cannot be abused into a large bill, is where the real engineering went.
