How it works
From chat export to living double in three steps.
Upload a chat
Export a conversation from WhatsApp (.txt) or Instagram (.json) and drop it in. ChatDouble detects the platform automatically.
We build the double
ChatDouble reads how one person writes — their slang, rhythm, and quirks — and turns it into a persona that texts like them.
Start chatting
Message your double in a chat screen that looks just like the app it came from. It replies in their voice, in real time.
Why ChatDouble
Uncannily them — down to the typos.
Their voice, not a bot's
ChatDouble learns the real slang, rhythm, and quirks from the chat — so replies sound like them, not a generic assistant.
Your data stays yours
Uploads are used only to build your own double and generate your replies. Never sold, never shared.
Pay only for what you use
Start with 100 free credits. Need more? Ask the administrator for an unlimited plan.
WhatsApp & Instagram
Bring back a group chat's funniest friend or an old Instagram thread — both platforms are supported out of the box.
Always ready to reply
Powered by Google Gemini with an automatic fallback, so your double keeps texting even when one model is having a moment.
Platform-faithful
The chat looks like the app it came from.
No generic chat window. Upload a WhatsApp export and you get WhatsApp. Upload an Instagram thread and you get Instagram — right down to the bubbles, ticks, and colors.

FAQ
Questions, answered.
What is ChatDouble?
ChatDouble turns a chat export into a “digital double” — an AI that replies in someone's real texting style. You upload a conversation, we learn how that person writes, and you can chat with a stand-in that sounds like them.
Which chats can I upload?
WhatsApp chat exports (the .txt file from “Export chat”) and Instagram DM exports (the .json file from “Download Your Information”). ChatDouble detects the platform automatically and mirrors that app's look in the chat screen.
Is my data private?
Your uploads are used only to build your own double and generate your replies — your chats are never sold or shared, and your data stays yours.
How do credits work?
Usage is metered in credits. You start with 100 free credits. Creating a double costs 20 credits, and each message costs one credit per word. Top up any time — 5 credits per ₹1, minimum ₹99. There is no subscription.
Is ChatDouble free to start?
Yes. Every new account gets 100 free credits — enough to create a double and start chatting. You only pay if you want to keep going, with simple pay-as-you-go top-ups.
Does it work for both WhatsApp and Instagram?
Yes. ChatDouble supports WhatsApp and Instagram, and the chat screen faithfully replicates the source app — a WhatsApp export gets the WhatsApp look, an Instagram export gets the Instagram DM look.

Upload a chat, meet the double. Your first 100 credits are free.
