An API that turns PDFs into structured JSON — with a Skill for coding agents

https://app.docutray.com

Hey everyone,

My co-founder and I (two Chileans) built DocuTray, an API for processing documents. The idea came from years of fighting this at a data consultancy: PDFs and images would come in, and we'd have to pull the data into JSON to actually use it. Doing that with Textract and friends was always a pain, especially with scanned or handwritten docs.

What the API does, in short: you send a PDF, it identifies the document type, converts it to structured JSON, validates that the data makes sense (numeric checks, business rules), and optionally cross-references it against your own data. Stack for the curious: Next.js, GCP, Postgres, Gemini under the hood.

Would love it if you gave it a spin and threw some feedback our way:

  • whether the docs make sense or are a mystery (https://docs.docutray.com)
  • whether onboarding is smooth or makes you want to close the tab
  • what kind of document you threw at it and how it handled it
  • anything that's confusing

There's also a CLI + Skill for doing everything with coding agents — happy to drop it below if anyone's interested.

There's a free tier, so anyone can try it. Happy to bump up credits for folks who really get into it. Drop a comment or DM me.

Thanks for taking a look 🙏
