About

Agnos is a document cleaning tool for Windows that prepares PDFs, Word files, Excel spreadsheets and web pages for AI systems and retrieval-augmented generation. It removes page numbers, headers, footers, cookie banners, placeholder text, broken characters and other junk that can confuse language models, while showing you exactly what was removed and why.

The app runs entirely on your own computer with no uploads or internet required. You can review each removal decision, keep pieces where the rule allows, or switch rules off. Agnos exports cleaned text in multiple formats and saves recipes for repeated cleaning tasks.

You get a 14-day free trial with no card required. After that, Pro costs $99 once for one person on two devices, or the Company Pack costs $399 once for up to five people on ten devices total. All version 2.x updates are included, and there is a 14-day money-back guarantee.

Agnos shows you every removal with its reason, so you can verify the cleaning is right for your use case. It runs locally on your PC with no uploads, and charges a one-time fee with no subscription or expiry on the licence.

Problem: PDFs, web pages and documents often contain page numbers, headers, footers, formatting junk and broken characters that confuse AI models and reduce the quality of retrieved context.
Solution: Agnos removes these elements on your PC before you send documents to AI systems, showing you what it removed and why so you can adjust the rules if needed.
