Buatin

(Context)

Manual entry is where budgeting apps lose people. Buatin lets a household log spending by chat, and keeps the books honest underneath.

(What I built)

  1. 01Deterministic ledger writes.
  2. 02Confidence-gated LLM classification. Anything uncertain goes to human review.
  3. 03Row-level security throughout, with a background worker for email and document jobs.
