Open WebUI & AnythingLLM
Last updated: May 2026
AnythingLLM by Mintplex Labs is one of our favorite projects in the local AI space. They've made private document Q&A genuinely accessible, the workspace-based approach to organizing knowledge is intuitive, and the team behind it is great. If you're looking for a straightforward way to chat with your documents locally, AnythingLLM is well worth a look.
