memobase is an open-source ai agents project by memodb-io (memodb-io/memobase on GitHub). It has 2,925 GitHub stars and 238 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 11 January 2026.
Decide what your chatbot should remember about each user across sessions — preferences, facts and profile traits — rather than treating every chat as new.
Clone the repo and check its documentation at memobase.io for the current deployment options.
Follow the project's docs to run the memory backend and connect your LLM, since profile extraction is LLM-driven.
Send a few conversations for one user, then start a new session and confirm the chatbot recalls the stored profile.
Builds long-term memory around user profiles rather than only raw message logs, per the project description.
Designed specifically as memory for AI chatbot applications.
Memory is meant to survive across sessions so returning users are recognized.
Implemented in Python, fitting the typical LLM application stack.
Apache-2.0 licensed and developed in the open by memodb-io.
Documentation and product information are published at memobase.io.

Yes, it is Apache-2.0 licensed open source. Running it still needs an LLM for profile extraction, whose costs depend on your provider.
Profile-based memory systems typically call an LLM to extract and update profiles, so expect to supply your own model key or a local model setup; check the current docs for supported providers.
Storing history replays raw messages. Memobase distills conversations into user profiles designed for long-term recall.
