Show HN: Pi-Foundry – multi user self hosted AI assistant
PAndreew Wednesday, January 28, 2026I wanted to solve my wife's work-related pain points revolving around Excel formulas and extracting data from PDFs documents by keeping her data locally. I also wanted to be able to collaborate with her if the need arises. So I've been working on this multi user virtual assistant based on the OpenCode SDK that we host on a Raspberry Pi behind Tailscale. The workflow in short - users upload their work files through the web interface, - add them to a chat session, - invite other users, - they churn the data with the agent, - then download the resulting assets. It has some rough edges especially around handling multi-turn conversations but thought maybe someone could find this useful. :) If you like it, please star and contribute to the project.
