Extract
Digital text, tables, headings, image references, captions, and page boundaries are extracted through multiple engines.
Verified document conversion
PDF to Markdown with page-level proof
Convert complex PDFs into Markdown: readable text with simple markers for headings, lists and tables. Use it for AI, search, documentation and archives. Every page gets a quality verdict.
For research, engineering, and document teams. Evaluation access requires account verification and KYAMOS approval. Already approved? Open the converter.

Critical values
Answer plus verdict
Multiple converters. Independent evidence. An honest result.
A normal converter returns text. KYAMOS runs independent extraction paths, compares critical values page by page, and preserves uncertainty instead of hiding it.
Verify
Optional OCR provides independent evidence for scans and difficult pages. It is checked, not accepted blindly.
Decide
Each page receives a score and a traceable verdict: confirmed, likely, uncertain, or failed.
Quality report
You can see what passed and what needs review.
The document verdict is derived from page-level evidence. A plausible-looking page is not enough.
Confirmed
All required checks passed with no unresolved page-level issues.
Likely
Conversion succeeded using a lighter evidence set.
Uncertain
Markdown is available, but one or more pages need review.
Failed
No usable verified result was produced.

Asynchronous API
Submit, poll, download.
Large documents continue processing after the browser disconnects. The web gateway uses KYAMOS account authentication and user-bound job tokens.
Direct API keys and batch endpoints are available for private pilots.

We do not believe in black-box document conversion.
PDFs contain operational memory: proposals, tables, legal terms, diagrams, and decisions. If a converter silently loses a row or changes a number, it corrupts knowledge. Our promise is clean Markdown, page-level proof, and honest uncertainty.

Before you upload.
Is this only optical character recognition?
No. Optical character recognition reads text from images. KYAMOS combines multiple PDF conversion engines, optional OCR, and page-level quality checks.
What happens when a page cannot be verified?
The document is marked uncertain. The quality report identifies the affected page, its score, and the unresolved evidence.
Can the service run privately?
Yes. VPN-only, customer-network, and self-hosted deployment are available for private pilots.
Are uploaded PDFs used to train models?
No. Customer files are not used for model training unless a separate written agreement explicitly permits it.

A conversion quality verdict is not a legal or scientific endorsement of the source document. Evaluation access remains approval-based.
