Your second brain, over WhatsApp
Every little thing, remembered
Reminders, tasks, habits, notes, briefings and money — all of it by message. There is no app to install and nothing new to learn: you already know how to send a text.
- 42 things to ask for
- no app to install
- works in the chat you already have
Everything worth keepingalready crossed your mind.Memo just catches it.
You already text yourself everything. Memo texts back.
The note-to-self thread, the voice memo you never replay, the message you send yourself at 1am. Memo is that habit, except something on the other end actually reads it.
The actual problem
You don't forget because you're careless
You forget because remembering costs something, and every tool built to help charges you up front.
The app you'd have to open
By the time you've found it, unlocked it and tapped into the right list, the thought has already gone. The tool costs more than the thing it stores.
The tab you'd have to switch to
Notes in one place, reminders in another, the thing someone told you in a chat you'll never scroll back to. Nothing is lost, exactly. It's just nowhere in particular.
The reminder that goes unread
A notification from an app you opened twice reads as noise. One from the thread you check all day reads as a message.
How it works
Three steps, and you already know all three
There is no fourth step. This is the entire setup, start to finish.

Save the number
One contact, like any other. No download, no account setup, no onboarding tour.

Send it the thought
However it comes out of your head. Half a sentence is fine. So is a voice note at midnight.
dentist tues 3pm, and remind me to move the car
- 03
Get it back when it matters
Memo files it, and returns it at the right moment — or the moment you ask.
Tuesday 3:00pm — dentist. Car reminder set for 8am.
What it does
Everything you'd otherwise keep in your head
Forty-two of them, by category. Flip through, or search for the one thing you came here to check.

End to end
The anatomy of a thought you'd otherwise lose
It arrives
Mid-shower, mid-meeting, mid-sentence. Never at a convenient moment.
You send it
One message, phrased however it came out. Two seconds, one thumb.
Memo sorts it
Reminder, task, note, someone's birthday, money you're owed — filed as what it is.
It comes back
At the time it matters, or the second you ask for it. Whichever comes first.
The honest version
Why not just keep doing it the way you do now?
You could. Here’s the swap, laid out flat — the left column is what you’re already living with.
The way you do it now
- An app you have to remember to open
- A note you have to remember to re-read
- Notifications you’ve learned to swipe away
- Six places a thought could have gone
- A syntax to get right before it saves
The way you’d do it with Memo
- The thread that’s already open
- It comes back to you, unprompted
- A message, in the app you answer
- One place, whatever kind of thing it is
- Say it however it came out of your head
Privacy
You're handing us your memory. We know what that's worth.
So here is exactly what happens to it, in the plainest terms we can write.
It's yours, and you can take it
Ask for everything Memo holds and it sends you the lot as a file. Ask it to forget something and it's gone — not archived, gone.
It only knows what you told it
Memo reads the messages you send it. It doesn't read your other chats, it isn't in your contacts, and it can't see anything you haven't handed over.
It isn't the product
Your memory isn't training data and it isn't inventory. The subscription is how this is paid for, which is the whole reason there's a subscription.
Questions people actually ask
Do I need to install anything?
No. Memo lives in WhatsApp. You message it the way you'd message a person, and it replies there.
Do I have to phrase things a particular way?
No. Write it how you'd say it out loud. “remind me to ring mum sat morning” works exactly as well as a formal command.
What does Memo store about me?
Only what you tell it, and you can ask for all of it back as a file — or ask it to forget any of it — at any time.
What if it gets something wrong?
Correct it in the chat and it updates. Anything scheduled shows you what it understood before it saves, so mistakes surface early.
Can I send it a voice note?
Yes. Talk at it the way you'd leave yourself a voice memo — it reads the message and files what's in it.
How do I cancel?
Type “cancel” in the chat. That's the whole process — no form to find and nobody trying to talk you out of it.
42 capabilities and counting
Stop trying to remember. Start telling Memo.
Save the number, send it one thing, and see whether it comes back at the right moment. That’s the whole trial.
