Your personal Memory AI Agent. Capture, recall, share. Memories that grow with the people you love.
Chat with an AI that knows when to save and when to recall. Build a shared memory space with your partner, family, or closest friends — on a privacy-first backend that's never sold to OpenAI.

Your memories, always with you.
Conversational Memory Agent
Chat with your AI. It decides when to save, when to recall, and when to answer — with transparent tool calls so you always know what's happening.
Shared Memory Spaces
Build a memory together with your partner, family, or close friends. Invite by email, co-write, recall together. Your shared moments, not a feed.
Privacy-first Self-hosted Backend
Your memories live on our self-hosted RAG backend, not in a third-party AI provider's logs. We don't sell your data. Your messages are processed by third-party AI providers, never used for model training.

How it works
How it works
Three steps. No complicated setup.
Tell your AI anything
Text, photos, or links. Just chat. The agent decides when to save it as a memory and labels it for later.
Ask anything
"What did Sarah say about coffee?" The AI searches across your memories and answers with citations you can expand.
Invite people
Create a shared memory space with your partner or family. Co-create memories together — not just a chat log.

Voice memos & transcription
Speak a memory; the AI transcribes, summarizes, and stores it with smart tags. Great for in-the-car capture.
Weekly & monthly recall digest
Auto-generated summary of last week / last month from your memories. A gentle reminder of what mattered.
Markdown export & data portability
One-click export of all your memories to plain Markdown — yours to keep, take with you, or back up.

1 Where do my memories live? Is my data sold?
Your memories live on our self-hosted RAG backend (LanceDB + LightRAG). We don't sell your data to anyone. To answer your questions, we send relevant content to third-party AI providers (OpenAI for chat, Google for embeddings only); both providers contractually do not train on your data. See the Privacy Policy for details.
2 Does it work across iPhone and Android?
Yes. Lumo is online-first; sign in on any device and your memories follow you. Pro tiers include cross-device sync; Free is single-device-write but cross-device-read.
3 Can I export or delete all my data?
Yes. You can delete your account and all related data from Settings → Account → Delete account. Cascade deletion completes within 72 hours. Markdown export is on the roadmap.
4 How do shared memory spaces work?
Create a container, invite by email with a role (editor or viewer). Both of you can write into the same memory space; recall queries it together. Owners can revoke invites or remove members at any time.
