  • AI Agentic Memory for beginners.
    This is usually a challenge that any developer has to take care of when building an AI agent. In fact, managing the context is one of the hardest problems when working with AI agents and there are many companies like SuperMemory, Mem0 which have invested both resources and time to solve this problem. - Source: dev.to / 14 days ago

    Looks nice! Would wait for the documentation to learn more. How does this compare to Notesnook? I have found that to be the best in terms of getting the details right (However, the last I checked, the documentation for self-hosting was unclear, and there were bugs in data exporting). https://notesnook.com/. - Source: Hacker News / over 1 year ago
