Well Extract
Well Extract is an open-source AI invoice data extraction tool that parses PDFs and receipt images into structured JSON using OpenAI, Anthropic, or Gemini models.
What is Well Extract?
Well Extract is an open-source, command-line AI tool that converts invoices and receipt images into structured JSON output by routing them through a user-chosen AI model — OpenAI, Anthropic Claude, Google Gemini, or a self-hosted Ollama instance — using a single npx command with no global installation required. Developers building FinOps tooling, expense management pipelines, or accounts payable automations regularly hit the same problem: invoice formats vary wildly across vendors, and rule-based parsers break as soon as a supplier updates their template. Well Extract sidesteps this by using vision-capable AI models to read document structure semantically rather than pattern-matching fixed field positions, producing clean JSON with customizable schema output. Because the tool runs entirely locally via CLI, financial documents never leave the developer's environment — a meaningful data-residency advantage for teams processing documents containing sensitive vendor or pricing information. Well Extract is purpose-built for developers comfortable with terminal workflows and AI API key configuration. Accounting teams or business users expecting a graphical interface, a vendor portal, or pre-built connectors to accounting software like QuickBooks or Xero will find the CLI setup requirements impractical without engineering support. It also extracts from invoices and receipts specifically — contracts, bank statements, and general business documents fall outside the current extraction schema.

Final Verdict
Well Extract fills the practical gap between expensive managed OCR APIs like Veryfi and fragile rule-based parsers by letting developers pick any vision-capable AI model and run extraction locally with full output schema control. The hard limitation is the technical barrier to entry: without CLI proficiency and API key management experience, initial setup is a genuine obstacle that excludes non-developer users entirely.
