On: Show HN: Linggen – A local-first memory layer for your AI (Cursor, Zed, Claude)

[Y_Y]

That's fine, but it's a very different claim to the one you made at first.

In particular, I don't know which parts of my data might get sent to Claude, so even if I hope it's only a small fraction, anything could in principle be transmitted.

That’s true — Linggen can’t control the behavior of Claude or any other cloud LLM.

What it can control is the retrieval boundary: what gets selected locally and exposed to the model. If nothing is returned, nothing is sent.

If a strict zero-exfiltration setup is required, then a fully local model would indeed be the right option.

I do have a local model path (Qwen3-4B) for testing.

The tradeoff is simply model quality vs locality, which is why Linggen focuses on controlling retrieval rather than claiming zero data ever leaves the device. Using a local LLM is straightforward if that’s the requirement.
