Teach it once
Swipe a message to "ignore" and WhatsAssist remembers the pattern — sender, wording, timing. No rules to write.
Early access · Android
You read the message.
The reply's already written.
WhatsAssist reads your incoming chats across WhatsApp, Instagram, Telegram and SMS, then drafts the answer — using what it remembers about each customer and exactly how you talk. You glance at it and tap send.

Smarter inbox
It learns your spam, not just your words.
Promos, "hi" blasts, the lead that ghosted you twice — you teach WhatsAssist what to ignore once, and it builds a filter that's yours. Drafts only fire for the messages that actually deserve a reply.

Why memory matters
Every reply, with the full context.
Most "AI for messaging" suggests three-word reactions. WhatsAssist drafts the actual answer — using what your customer told you last week on a different app, what you promised, what they ordered, what they care about.
- Remembers the last conversation, automatically.
- Surfaces the source so you can verify before you send.
- Forgets in one tap when you ask it to.
Your messages are yours.
We process only what's needed to draft a reply. Memory is encrypted at rest. We never train AI models on your conversations. We never sell or share your data. You can delete everything in one tap.

Questions worth answering
Frequently asked.
Can't find what you're looking for? Email support@opergen.com — we reply within 24 hours, usually faster.
Will WhatsApp ban my account?
No. WhatsAssist drafts replies — you send them. Nothing leaves your phone without your tap, so your account behaves exactly like normal. We do not send bulk, we do not blast, we do not automate.
How is this different from Gboard Smart Reply or Apple Intelligence?
Those suggest one-tap reactions ("OK", "Sure"). WhatsAssist remembers what your customer asked last month and drafts the actual answer using your business knowledge. It is the difference between a reflex and a memory.
Is it really an auto-responder?
No. Auto-responders fire pre-written templates when a message arrives. WhatsAssist drafts a personalized reply and waits for you to tap send. You are always in the loop.
How fast is setup, really?
About a minute. Install, flip on message reading, describe your business in a sentence, and your first draft appears. No new phone number, no cloud bot, no migration.
What data do you collect?
The minimum needed to draft a reply: message text and sender name from notifications you choose to enable. Memory is stored encrypted. We never train AI on your messages and never sell data. Full details in our Privacy Policy.
Does it work offline?
Memory and history are stored locally. Drafting needs internet (the AI runs in the cloud, encrypted in transit). If you are offline, your message history stays accessible.
Which apps work?
WhatsApp, WhatsApp Business, Instagram DMs, Telegram, Messenger, SMS, Signal. We are adding more based on what users ask for.
Is there an iOS app?
Coming in 2026. iOS notifications work differently, so we are doing it right rather than fast. Email support@opergen.com to be notified.
What if I have multiple WhatsApp accounts?
Business plan supports multi-account on the same device. Personal + Business WhatsApp, two SIMs, dual-app — handled.
Will it work on my Xiaomi / Realme / Oppo?
Yes, but those phones aggressively kill background apps. We have a one-minute setup guide for your specific model. You will see it after install.
How do I cancel?
One tap in Settings → Subscription, or directly in your Google Play account. No retention call, no friction.
Stop typing the same things twice.
