The chat with yourself, upgraded

You already text yourself.
Now it texts back.

Screenshots, addresses, the wifi password, the thing to do on Friday — you’ve been dumping them into a chat with yourself for years. Same habit, same WhatsApp. Except this one reads what you send, finds it when you ask, and brings things back before you need them.

Open the app

Free, no sign-up. Works in the browser; add it to your home screen for notifications.
WhatsApp is paused for a few days while Meta reviews our account. Everything works in the app.

You already do this

The self-chat, with the missing half.

Your chat with yourself

Scrolls away after a week.
Search finds the exact word, if you remember it.
A screenshot is just a screenshot.
Never reminds you of anything.
Knows nothing about you.

my 2nd brain

Ask in plain words: “what’s the wifi at Sector 53?”
Finds it by meaning, not by the word you used.
A screenshot becomes the code, the amount, the expiry.
Anything with a date comes back on its own.
Remembers who Avani is, and what you take each morning.

How it works

Same as texting yourself. One extra step.

1
Say hi on WhatsApp
Tap the button, send “hi”. That’s the whole sign-up. From here it’s a chat like any other.
2
Dump things in, like you already do
A line, a voice note, a screenshot, a PDF. It works out what each one is — something to keep, something to remind you about, something for a list.
3
Ask for it, or let it come to you
“What’s the wifi at Sector 53?” “Send me my boarding pass.” And anything with a date comes back on its own, at the right moment.

What goes in

The things you’d dump in that chat.

🎟️
The voucher screenshot
Forward it. Code and expiry kept; a nudge two days before it lapses.
📶
The wifi password
“Wifi at Sector 53 is Jio_5G, mehta2024.” Back in one line, three weeks later, when you ask.
⏰
The thing to do on Friday
“Remind me to call the plumber Friday at 6.” A nudge at 6 on Friday. Nothing before.
✈️
The boarding pass
Send the PDF. The file itself at the airport, and a nudge that morning.
🎂
Amma’s birthday
“Amma’s birthday is 14 March.” The morning of, every year. No calendar to keep.
🛒
The grocery list
“Add paneer to the list.” The whole list at the shop, when you ask.
💊
The prescription
“Antibiotic twice a day for 5 days.” Nudges that stop by themselves on day five.
🔗
That link you’ll want later
A blog post on Delhi’s winter markets, “save for November.” It, in November, or whenever you ask.
🦵
The physio sheet
The PDF, “remind me every morning.” The exercises with a 7 am nudge, daily.

Consent and control

Nothing you didn’t ask for.

We only nudge you because you asked. Every reminder exists because you set it. Notifications only if you switch them on.
Say stop, and everything stops. One word. No menus, no reason required.
Delete everything, whenever. Say “delete my data” on WhatsApp, or one tap in the app, and every reminder, list, note and fact is gone. How deletion works.
Not a chatbot. It won’t answer trivia or write your emails. Reminders, lists, notes — that’s the whole of it. Privacy policy.

What it costs

Nothing, while we’re new.

No card, no trial clock, no limits. If that ever changes you’ll hear it from us first, in plain words. No advertising, ever.

Prefer an app?

There’s one. It’s the same brain.

A standalone app that syncs with WhatsApp

Add it to your home screen from app.my2ndbrain.in. No account; the app gives your phone a code and that’s your login.

Reminders as app notifications

Turn on notifications and every reminder arrives as a push, in the app and on WhatsApp both. Use whichever you see first.

One memory across both

Set something in the app, ask about it on WhatsApp. Send a screenshot on WhatsApp, find it in the app. Connect the two once and they stay one account.

Connect them in a minute

App menu → WhatsApp → Connect. It gives you a code to send. How connecting works →
