Kurumi (クルミ, "walnut" in Japanese — because it looks like a brain) is a personal memory assistant built as a local-first PWA. It captures typed notes, voice memos, and meetings, then helps you recall and act on them with AI. Everything works offline, syncs through your own infrastructure, and routes inference between on-device models and remote APIs.

- Capture first, chat second. Friction to save a thought should be near zero.
- Local-first, not local-only. Everything works offline; remote is the fallback.
- Human-in-the-loop. The assistant proposes, you approve.
- Plain text at heart. Markdown bodies, YAML frontmatter, exportable. No vendor lock-in.
- Policy-routed inference. Tasks pick local vs. remote based on capability and preference.
- Your data, your control. No account, no server, no tracking. Export anytime.
