Agnos

What makes it different

Agnos is a Windows app that cleans documents before they go into an AI chatbot, a RAG knowledge base or training data. Drop in PDFs, Word, Excel, PowerPoint or web pages, and it strips the parts that are not content: repeated headers and footers, page numbers, cookie banners, boilerplate and duplicates — while keeping tables, code and numbers.

The part its maker cares about most is that nothing is removed silently. A review list shows what was removed from each file, with the rule behind every removal, so you can keep a piece or switch its rule off. Exports come as JSONL chunks, cleaned text or training data.

Everything runs on your own Windows PC; nothing is uploaded. Agnos is free for 14 days, then $99 once.

Agnos is made by Michael Shadpour at Gidion and launched on Product Hunt on 1 November 2026. He tested it on 25 public PDFs from US federal agencies — 1,342 pages in all — and published the results.
