The Story

A friend was going through a divorce. Financial disclosures, custody agreements, years of communication records — hundreds of pages, and her lawyer billed $400/hour to read through them. She asked me: “Can't AI do this?”

I built the entire product in 14 days using a CLAUDE.md autopilot workflow — every code change automatically linted, tested, committed, deployed, and documented itself. The result: a full production SaaS with auth, payments, a RAG-powered AI pipeline, streaming document generation, court form auto-fill, and 341 tests.

The biggest lesson wasn't technical — it was that distribution matters more than features. ArguLens has streaming doc gen, FJC form pre-fill, and a feedback flywheel. But finding users as an H-1B visa holder who can't publicly market is the real unsolved problem. That's why I built the free SEO tools — organic distribution that works while I sleep.
