## About

Transmutify turns the files your customers actually send you — messy Excel exports, CSVs with weird headers, raw text, even photos of tables — into clean data that matches your schema.

How it works:

1. Define your target schema (or let it be generated from an example).

2. Send a file via the API or upload it in the playground.

3. AI proposes the column mapping to your schema.

4. Every run returns a hosted review URL: whoever knows the data checks the mapping, fixes values, and approves. No AI output enters your system unreviewed.

5. You receive clean, schema-conform records via webhook or download.

Built for B2B products where customer onboarding means "please send us your employee/user/product data" — and someone ends up massaging spreadsheets by hand.

What makes it different:

- Bring your own AI keys — it runs on your OpenAI/Anthropic account, so your data doesn't route through our AI contracts and you control model and cost.

- Bring your own storage — files can live in your S3 bucket.

- Human-in-the-loop by design — AI proposes, people approve.

- API-first — your app owns the upload and the results; Transmutify handles mapping, review, and delivery. Dry runs let you test the whole flow without provider calls.

- AI-agent-ready docs — Claude Code or Cursor can integrate it for you in an afternoon.
