Don't Write Schemas. Discover Them.

Upload a sample document. AI analyzes it and suggests a complete schema. Edit it, refine it, publish it — zero AI calls for iteration.

How Discovery Works

Step 1
Upload a Sample

Upload a representative document — an invoice, purchase order, receipt, or any file type you want to extract from.

Step 2
AI Discovers Fields

The AI analyzes the document and suggests a complete JSON Schema — field names, types, descriptions, and structure.

Step 3
Refine & Publish

Edit the suggested schema in the visual editor. Add fields, remove others, adjust types. Publish when ready.

Zero-Cost Iteration

Edit Your Schema as Many Times as You Want

When you run discovery, the raw AI output is stored as a reference extraction. Every schema change re-maps fields from this reference — no AI calls, no credits consumed.

  • First discovery: 1 credit (AI analyzes the document)
  • Schema edits: 0 credits (instant field re-mapping)
  • Add/remove fields: 0 credits (local matching)
  • Change field types: 0 credits (local matching)

How the Field Matcher Works

1.
Exact match — Field name matches exactly
2.
Normalized match — invoice_number → invoiceNumber
3.
Description match — Semantic similarity to field description
4.
Alias match — Common aliases (e.g., "amt" → "amount")
5.
Fuzzy match — Levenshtein distance for typos

All matching happens locally. No AI provider calls. Instant results.
