Hi Product Hunt 👋
I built Klartext because extracting usable content from PDFs and scanned documents is often more complicated than it should be.
Many existing tools require paid API credits, send documents to external AI services or produce poorly structured output. Klartext processes the files on my own server and converts them into clean Markdown and structured JSON.
I tested it with real-world PDFs, Office documents, spreadsheets, images and scanned historical documents. The service is still at an early stage, so honest feedback is especially valuable.
I would love to know:
• Which file formats should I add next?
• How useful is the generated Markdown for your workflow?
• Did any document fail or produce incorrect output?
Thanks for trying Klartext!
Markdown has no way to express a merged cell, and scanned documents are full of them — invoices especially. What happens when a table doesn't fit the grid: does it fall back to HTML inside the Markdown, get flattened, or move over to the JSON side where the structure survives? That choice decides whether the output is readable or usable.
the self hosted approach is honestly really nice, but it would help a lot if you could add a way to preserve the original document layout in the markdown output, like keeping tables and headings numbered exactly as in the source pdf, since right now it kind of flattens everything and you have to manually fix it later
