A companion that grows with you.
Lumi learns your voice, your rhythms, and the people who matter. Yours to see. Yours to delete. Always.
Lumi acts.
The others just talk.
Here are six things Lumi can do today that ChatGPT and Hey Google can't. None of these are mockups — they're real conversations.
Side by side, honestly.
Where Lumi wins, where it doesn't. We left the wins for the others in too — because we want you to actually trust this.
| ChatGPT | Hey Google | Lumi | |
|---|---|---|---|
| Remembers across conversationsChatGPT has Memory but it's opaque. Lumi shows you every memory and lets you delete them. | ~ | ||
| Rings your alarm at a specific timeHey Google sets dumb timers. Lumi understands 'wake me gentle' and uses your phone. | |||
| Sends real emails for youChatGPT has Actions but they're flaky. Lumi uses your Google account directly. | ~ | ||
| Searches your photos by what's in themGoogle Photos can — but in a separate app, not in chat. Lumi does it inline. | ~ | ||
| Reads notifications you allow → remindersNobody else does this. It's the most underrated thing Lumi does. | |||
| You can see and delete every memoryBoth competitors keep their memory opaque. Lumi shows you the list. | |||
| Open source and self-hostableRun the whole thing on your own GPU if you want. | |||
| Raw conversational smartsHonest: GPT-4 / Claude beat us on pure model capability. We're catching up. | ~ | ~ |
Quietly there.

Talk. Be heard.
A small library of curated voices. Or your own — if you're on Pro.
- "Hey Lumi" wake word
- Talk over it mid-sentence — it stops
- Knows your voice on shared devices
- Voice cloned from a 30-sec samplePRO
Honest take: cloning works for short, calm sentences. Don't expect a perfect impression.
Same Lumi, different mood.
Tap a name. The memory, calendar, and alarms stay — just the voice changes.
Your stuff.
Yours to keep.
Yours to delete.
We're a small team running shared infrastructure. That doesn't mean less honesty — it means more.
We never sell or train on your stuff
Your messages, photos, and memories don't feed anyone's model. Ours or anyone else's.
Every memory is yours to see
Tap any fact Lumi has learned about you. Edit it. Delete it. Forget the lot.
Connect what you want, when you want
Gmail, Calendar, Drive — opt-in one at a time. Disconnect in one tap.
Delete your account in one tap
30-day grace if you change your mind. After that, gone for real — files, photos, the lot.
Honest about the cloud: Lumi runs on our servers, not yours. Your data sits in its own walled-off space, but it's still our hardware. If you want it on hardware you own, you can self-host the whole thing — it's open source.
Get on the list.
