Per-conversation memory
Each contact carries its own context — what they ordered, what you promised, how you usually talk. The next draft already knows.
WhatsApp reply assistant
The reply already knows what to say.
ToTa-Ai reads the message, remembers the whole conversation, and drafts your reply in your own voice. It opens the chat with the draft ready — you read it, change a word if you like, then you send. It never sends for you.

How it works
Four taps from read to sent.
ToTa-Ai sits beside WhatsApp, not inside it. It listens for new messages, drafts a reply, and hands the chat back to you — open and ready.
01
It reads the message
ToTa-Ai sees the incoming WhatsApp message through Android's notification access. No accessibility tricks, no screen reading.
02
It drafts the reply
Using what it remembers about that contact and the way you write, it composes a reply with a confidence read on it.
03
It opens the chat
One tap on Open in chat takes you straight to that person's WhatsApp thread with the draft already typed in.
04
You send it
Read it, tweak a word, then press send yourself. ToTa-Ai never pushes a message on your behalf.
The one that saves the most time
"Open in chat" lands the draft in the conversation.
Other tools stop at the clipboard. ToTa-Ai resolves the contact to a phone number and deep-links straight into their WhatsApp thread — draft pre-filled, cursor blinking, send button one tap away.
- Right chat, every timeMatches by your saved contacts, with a manual phone override for nicknames and emoji names.
- Groups handled honestlyGroup threads can't deep-link, so the draft copies to your clipboard and WhatsApp opens — no broken promises.
- You always press sendThe draft arrives ready, but the final tap is yours — by design, and by WhatsApp's rules.
What's inside
Memory and voice, not magic.
Your voice, learned
Drafts read like you wrote them, in the register you actually use — not a polite corporate template that fools no one.
Confidence read
Every draft shows a high / medium / low signal so you know when to skim and when to read closely before sending.
Schedule a reply
Not the moment to respond? Pick a preset — tomorrow morning, weekend start — and ToTa-Ai keeps the draft ready for then.
Floating draft bubble
A small bubble floats over WhatsApp so you can drop the draft in without leaving the chat you're already reading.
Review senders
You approve who ToTa-Ai pays attention to. Pending, approved, blocked — your inbox, your call.
Privacy by construction
Built to read, never to act behind your back.
ToTa-Ai is deliberately limited. It reads message notifications to draft a reply and resolves contacts to open the right chat — and that is the extent of its reach.
- No autonomous actionsNo AccessibilityService automation — that's banned by Google Play policy, and we don't want it anyway.
- Memory stays on your phoneConversation memory and contacts live in a local database on your device, not on our servers.
- Drafting is the only network callMessage text goes to the AI provider only to write the draft. Nothing else leaves the device for that.
- Reset anytimeOne tap clears all stored conversations and contacts. A hard reset wipes everything ToTa-Ai knows.

Questions
The honest answers.
Does ToTa-Ai send messages on its own?
No. This is the core rule of the app. ToTa-Ai writes a draft and opens the chat with it pre-filled, but the send button is always yours to press. Automating sends on a personal WhatsApp account is against WhatsApp's terms, and we built around that on purpose.
How does it read my WhatsApp messages?
Through Android's notification access, the same mechanism a smartwatch uses to show your messages. You grant it explicitly in Settings, and you can revoke it anytime. ToTa-Ai does not use accessibility services to read or tap your screen.
Where is my data stored?
Conversation memory and contacts are kept in a local database on your phone. When a draft is generated, the message text is sent to the AI provider to compose the reply — that is the only data that leaves your device, and only for that purpose.
Does it work with groups?
Yes, with a caveat. Group chats can't be opened by a direct link the way one-to-one chats can, so for groups the draft is copied to your clipboard and WhatsApp opens — you paste it into the group. ToTa-Ai tells you clearly when that's the case.
Which Android versions are supported?
Android 8.0 (Oreo) and newer. ToTa-Ai is built fresh in Kotlin and Jetpack Compose — no legacy baggage.
Is it free? Is it open source?
The v1 client is licensed Apache-2.0. It's an early, founder-built tool — request early access below and we'll get you a build.
