Mem0 is a memory layer for AI agents and assistants that pulls out important facts from conversations, stores them, and brings them back later so replies can be personal.
In plain words
Chatbots normally forget you once a conversation ends. Mem0 sits beside the model. As you chat, it extracts the key information, such as your preferences, merges it with what it already knows, and retrieves the relevant memories when needed. Its research paper reports much lower latency and token cost than sending the whole chat history each time. It comes as an open-source library, a self-hosted server or a managed cloud platform.
A quick example
Imagine telling a support bot once that you are vegetarian and live in Lisbon. Weeks later you ask for dinner ideas. With Mem0 attached, the app looks up stored memories about you, finds those two facts, and passes them to the model so its suggestions fit.
