Take the work
off your plate
Lem gets to know you, remembers what you tell it and works on every front of your life so you can focus on what matters. With real privacy and security, and always under your control.
It feels like texting someone
A single conversation, like chatting with someone who never forgets. Tell it what you need and it takes care of it; send photos, PDFs or voice notes and it understands them.
Works on your goals even when the app is closed
Give it a goal and it builds a plan, checks in when it's time and comes back with ideas. If it finds something or needs you to decide, it messages you first.
Connected to your email, calendar and files
Connect Gmail, Google Calendar, Google Drive or Outlook. Lem reads, searches and organizes for you, and opens attachments and documents to understand them.
Knows where you are, if you want it to
When you arrive at or leave a place, Lem gets the signal, even with the app closed and barely using battery. That way it understands your day and reminds you of things right where you need them.
Remembers everything, for real
Every night it writes in its diary what happened and keeps your files in order. Weeks later it still knows who's who, what was agreed and what's pending.
Diary

Your data is yours
Lem does things for you, but never behind your back.
You approve what matters
Before sending an email, creating an event, moving a message or uploading a file, Lem shows you exactly what it's going to do and waits for your “Approve”. It can't approve itself.

Passwords the AI can't see
Your passwords and connections are stored encrypted. Lem uses them when needed, without ever seeing them.
Your space, only yours
Each person has their own isolated space: conversation, files and connections.
No ads
Your data is not sold, not used for ads and not shared. Read the privacy notice.
Ask it the way you'd
ask a person
Got an invitation?
For now Lem is private and only works on iPhone. If someone invited you, open the link they sent you: it has your code and these steps.
Install TestFlight from the App Store, then Lem from your link.
Open Lem, tap “I have an invitation” and enter your code.
Tap Continue with Apple. Lem guides you through the first steps.
What you want to know
What is Lem?
A personal AI you talk to like a person, in a single conversation that never forgets. Beyond answering, it works for you: it follows your goals, checks your email and calendar, reads your documents and messages you when there's news.
Does it keep working if I close the app?
Yes. When you give it a goal, Lem schedules its own check-ins and wakes up on its own when it's time. If it finds something or needs you to decide, you get a notification.
Does it ask before acting?
Whenever it's about to change something outside Lem: sending an email, creating an event, moving a message or uploading a file. It shows you exactly what it will do and doesn't do it until you tap “Approve”.
What does it do with my Google or Outlook data?
It only uses it for what you ask. It doesn't sell it or use it for advertising or to train models, and you can disconnect the account whenever you want. The details are in the privacy notice.
How much does it cost?
For now Lem is invite-only and free for those who receive an invitation; each person has a daily message limit.
Which devices does it work on?
iPhone, with the Lem app. Location and notifications work even when the app is closed.
What language does it speak?
The app comes in English, Spanish, Portuguese and French (it follows your iPhone's language), and Lem talks to you in that language.
