Export a WhatsApp chat and this reconstructs how that specific person actually texts — the slang, the Hinglish, the one-word replies, the “kal dekhte hain” energy — not a generic chatbot doing an impression of them.
Try it tonight, free:
- Export the chat — WhatsApp → chat → Export Chat → Without Media. You get a
.zip(works from iPhone or Android).
proof: unzip it, there’s a .txtinside. - Upload the zip at onlinekotha.com.
- Send it a message. proof: the reply either sounds like them, or it sounds like generic ChatGPT — that’s the actual test.
There’s also a plain chat viewer and an “On This Day” tab that resurfaces old messages from the same date, past years.
Free tier, pricing, and who's actually building this
Free = import chats + a handful of AI replies per day, no card needed.
Paid = $6/month for more AI replies — the founder’s word is he’s not pushing that first, he wants to know if the reply feels like the person before anyone pays for it.
Built solo, shipped at night, based in India — first time putting it in front of strangers instead of just friends. He’s specifically fine with “this is a bad idea” as feedback.
People testing it so far have used it for: an old friend, a long-distance partner, a parent, digging through their own message history, or just “what would they say” — and some said never, too private, which is a fair answer too.
If you try it, the one thing worth reporting back: did the first reply sound like them?
