“Kal 11 baje client call hai, usse pehle deck bhejna hai aur Rahul ko follow-up karna hai”
Done ✅ 3 things for tomorrow: • 10:00 — send the deck • 10:30 — follow up with Rahul • 11:00 — client call
Told Neha I'd review her proposal by Thursday
🤝 Tracking it: review Neha's proposal — due Thursday. I'll remind you Wednesday evening.
What did I promise people this week?
3 open promises: • Neha — proposal review (Thu) • Rahul — pricing sheet (Fri) • Arjun — intro to the design team
It's not the big tasks you forget
It's the small promises — made in passing, on calls, in corridors — that quietly slip.
“I'll get back to you” — and you didn't.
Meeting action items vanished the moment the call ended.
Manager ne 1:1 mein kuch bola tha… kya tha?
Follow-up email went 2 weeks late — the deal cooled.
Work took over — bills, gym, mom's call all slipped.
Tasks spread across Slack, email, sticky notes and your head.
Ab nahi. One WhatsApp message, and it's tracked till it's done. 🙌
Say it once. It's tracked.
Tap a situation from a typical workday.
Walk out of every meeting with action items captured.
Send it between meetings — typed or as a voice note. No to-do app to maintain.

Much more than a reminder bot
It keeps learning who and what matters to you — so it gets more useful every week.
Reminders & tasks
One-time, daily, monthly, yearly — set from a single sentence, delivered on WhatsApp in your timezone.
Memory
Tell it where you kept something, a number, a detail — ask for it back anytime, in plain words.
People
It remembers who's who — what you owe them, what they owe you, what you promised.
Promises & follow-ups
Said “I'll get back to you”? It tracks it and nudges you before it goes cold.
Voice notes
Too busy to type? Just speak — Hindi, English or a mix of both.
Morning briefing
Start the day with one message: today's reminders, dues and follow-ups.
Snooze & reschedule
“Kal karta hoon” works. So does “1 ghante baad yaad dilana”.
Web dashboard

Aapke sawaal
Does it connect to my calendar, Slack or email?+
Not yet. Today it works through WhatsApp — tell it, or forward it, what matters. Integrations may come later.
Should I send confidential work data?+
Treat it like a personal notebook: great for tasks, promises and context. Don't send passwords or confidential client data.
Do I need to install an app?+
No. You create a free account on this website once, connect your WhatsApp, and from then on everything happens inside WhatsApp. The web dashboard is optional.
Kya yeh Hindi samajhta hai?+
Haan! Hindi, English, Hinglish — typed or as a voice note. Write the way you normally text; there's no special format to learn.
Is it a chatbot I can ask anything?+
No — and that's on purpose. It's focused on one job: remembering your tasks, dates, promises and details, and reminding you at the right time. It does that job really well.
Is my data private?+
Yes. Your messages and memories are yours — never sold or shared. You can delete a memory, or your whole account, anytime.
What if I ignore a reminder?+
Reply “1 ghante baad” or “kal” and it snoozes. Reply “done” and it's closed. Anything left open shows up in your morning briefing.
Is it really free?+
Yes — the Free plan covers real day-to-day use, not a crippled trial. Paid plans with higher limits are coming soon.
