    Kai – a private, offline AI "second brain" that remembers you(no cloud)▲5

    I built Kai because I was tired of assistants that forget and cloud tools that mine my data. Persistent memory: what you teach Kai sticks. Local-first: data never leaves your device; no telemetry. Transparent: memory graph shows what it knows and why. I’m looking for early users who care about local, privacy, and explainability. The landing page has a simple waitlist; I’ll onboard in small waves and share progress.
