Privacy
Data processed and stored on Moonshot AI infrastructure in China. Not recommended for sensitive personal or business data.

KimiClaw pros
- Zero setup — works immediately in your browser tab, no server required.
- Largest managed skill ecosystem via ClawHub (5,000+ community skills).
- 40GB cloud storage enables large-context RAG workflows across sessions.
Letta pros
- Open source with transparent code and flexible deployment options.
- Strong privacy story for users who care where data runs.
- Good memory and persistence support for ongoing conversations or tasks.
KimiClaw cons
- Hosted by a Chinese company — low privacy score, unsuitable for sensitive data.
- No self-hosting option; fully dependent on kimi.com availability.
- Limited native channels (web + Telegram only; others require BYOC bridging).
Letta cons
- Lower autonomy — designed more as a platform than an out-of-box assistant
- Setup requires understanding memory architecture concepts
- Python-only — no native TypeScript/JavaScript implementation
KimiClaw gotchas
- BYOC requires you already have a running OpenClaw instance to bridge.
- Skill quality in ClawHub varies widely — community-contributed skills are not curated.
Letta gotchas
- You should expect ongoing hosting, uptime, and secret-management work if you deploy it for real users.
- Recurring subscription or model spend can matter more than the headline feature list.
