I started building things like this as browser extensions to make the hosting simpler.

interesting，but will it have official GUI？

I use mostly typst for pdf generating today i have written different frontends and connectors to transform everything into typ files and templates. I eben use it with sphinx as a backend

Great work. But why you are using AI for build such a service, it does not need an AI.

Can I use it with Open-Webui instead of Apache Tika?

Is this PDF engine vibe-coded and derived from reading the MuPDF source code? (Written from C to Rust) I see some slight references to MuPDF in certain places.

If it is you should disclose it and the license should be AGPLv3 instead of Apache.

Would be useful to have a remove password feature (for a known password) and support for adding signatures

I think there's a difference between a standard PDF viewer and basic functionality, vs a full PDF authoring suite like Adobe. For some of the basic features in one of the comments, I'm not quite sure how tried and tested tools that are simple like Foxit PDF don't fit the bill for most things. Unless you're trying to process gobs of PDFs in headless mode or do some sort of analysis... eh.

Nice work.

Love the web interface! But can it be done better?

First, how do you "sign" a PDF?

If you're going to build this, can you find a small, even tiny model that has decent tool calling and, effectively turn that in combination with this tool into a single HTML page that I can use everywhere?

Literally something I could save on a work laptop or cloud desktop and would actually work (even if it would be slow, it'd still be a great improvement)
