What Manvi can do

Everything you need,
nothing you don't

Seven core features designed around how you actually think and text — not how productivity apps want you to think.

⏰
Reminders
One-off or future-dated. Set a reminder in plain English — exact time, relative time, or a specific date. Manvi fires it at the right moment over WhatsApp.
"Remind me to check the oven in 20 minutes"
🔁
Daily Routines
Set a recurring task at a fixed time and it runs every day automatically — no expiry, no end date, until you delete it.
"Remind me to drink water every day at 10 AM"
🎂
Birthdays & Events
Save a date once, get reminded every year. Manvi sends an advance alert the day before and a fresh alert on the day itself at 8:30 AM.
"22nd May is Manu's birthday"
🔍
Web Search
Ask anything current. Manvi searches the web via Tavily (with Serper as fallback) and returns a clean, concise summary — no links, no fluff.
"Who won the match last night?"
📇
Contacts & Messaging
Save contacts by name. Ask Manvi to forward a message to anyone in your address book — she resolves the number and dispatches it instantly.
"Tell Ravi I'll be there at 7"
💬
Conversational AI
When you're not managing tasks, just talk. Manvi runs a 4-tier AI waterfall (Gemini → Groq → OpenRouter) and always keeps a fallback ready.
"Explain quantum computing simply"
How it works

From text to action
in under a second

1
You send a message
Plain English, in WhatsApp. No commands, no syntax. Just say what you need.
2
Manvi reads intent
The AI waterfall extracts intent, time, date, and target from your message in under 500ms.
3
Action is executed
The right handler fires — reminder saved, contact messaged, search run, routine scheduled.
4
You get notified
At exactly the right time, Manvi sends the reminder or event alert back to your WhatsApp.
Self-host in 15 minutes

Full control, zero cost.
