Why it matters

For anyone loading company documents into ChatGPT, a custom GPT or a retrieval system. Junk text like headers and banners hurts AI answers, and Agnos removes it on your own PC, so sensitive files aren't uploaded anywhere.

Highlights

Cleans PDFs, Word documents, Excel files and web pages, removing page markers, web page clutter and placeholder text.
Repairs broken characters, for example garbled accents and apostrophes.
Shows what it kept and removed with the rule behind each removal; you can keep a piece or switch a rule off.
Runs on your own computer with nothing uploaded, and works with the network off, according to the site.unverified
Comes with a sample project of five made-up files so you can watch each step before adding your own.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You're about to load a folder of PDFs or spreadsheets into an AI tool and want the junk stripped out first, without uploading anything.
