I am looking for a similar service that turns any document (PNG, PDf, DocX) into JSON (preserving the field relationships). I tried with ChatGPT, but hallucinations are common. Does anything exist?

I built a drag-and-drop document converter that extracts text into custom columns (for CSV) or keys (for JSON). You can schedule it to run at certain times and update a database as well.

I haven't had issues with hallucinations. If you're interested, my email is in my bio.

This is also using OpenAI's GPT model. So the same hallucinations are probable here for PDFs.
