Moss — Persistent remembering. The AI memory Claude and ChatGPT can't match.
Every AI remembers you now. Only Moss remembers the details. ChatGPT and Gemini remember the gist — a summary of you, fetched on demand. Moss remembers the specifics: the show you turned off after one episode, the idea you already ruled out, the gift you bought last year. It stops re-pitching what you've passed on, stays accurate at 7M+ tokens, and surfaces the relevant detail before you ask. See the benchmark →
Why Moss is different
- Context is carried, not fetched. Moss brings relevant memory into every message proactively. You don't say "remember when we…" — Moss already did.
- Accurate recall at scale. 7M+ tokens of memory with retrieval quality that stays sharp where frontier LLMs start to blur.
- Cross-conversation by default. A detail from three months ago surfaces in today's chat, without a thread lookup or a manual reminder.
- Server-side model orchestration. Moss picks the right model — Claude, GPT, Gemini, Groq, or Perplexity — for each memory operation. You don't manage models. You get better answers.
How it works
- Chat naturally — Moss learns from every conversation. The more you talk, the sharper its model of you gets.
- Import your history — upload Claude, ChatGPT, or Gemini exports. Moss extracts semantic units, indexes them permanently, and makes every past conversation searchable.
- Ask anything — Moss combines your personal memory with live web research for context-rich, grounded answers.
- Your data is yours — row-level security on every table, export on demand, never trained on.
