SimuChatPrepare a difficult conversation before having it for real
Breaking bad news, apologising, saying no, bringing up a touchy subject: we often turn the same sentences over and over in our heads. With SimuChat, you can try them on a simulation of the person, who replies with their usual words and tone.

Context : I'm going to tell her I can't come to her birthday
hey, I need to tell you something about saturday
uh oh that doesn't sound good 😅
I won't be able to make it, I've got a work thing I can't move
seriously?? it's my 30th
ok you're terrible but I get it… dinner the week after then
Why practise before a delicate discussion?
When the stakes are high, we either write too fast or stop daring to write at all. Rehearsing the exchange helps you find the right words, spot phrasings that might hurt and anticipate objections. You come to the real conversation calmer, knowing what you want to say and what might go wrong.
How SimuChat imitates the person
SimuChat analyses your real conversations: the length of their messages, their punctuation, emojis, expressions, rhythm and how they react when things get tense. The AI relies on this profile and on excerpts of your messages to answer as they would. You can add notes ("she hates it when people beat around the bush") to refine the simulation.
Set the context, then write your message
In the Context field, describe the situation: "I'm going to tell him I'm moving", "we argued yesterday", "I have to turn down her invitation". Then write your first message as you would send it. If you don't like the reply, start again with different wording: each attempt helps you find the right approach.
Stay in control of the real conversation
The simulation is practice, not a prediction. It helps you clarify how you feel and choose your words, but the real person is free to react differently. Use it to prepare, then talk to them for real.
How it works
Three steps, a few minutes.
- 1
Export your conversations
From WhatsApp, Instagram, Messenger, Snapchat, TikTok, Android SMS or your iPhone (with the free Windows app). The guide walks you through every step.
- 2
Import them into SimuChat
Importing is free. SimuChat works out who wrote what and builds each contact's writing profile: message length, punctuation, emojis, favourite expressions, rhythm.
- 3
Chat with the simulation
Write as usual: the AI answers with their words, their humour and their rhythm, based on your real conversations.
Frequently asked questions
Will the simulation react exactly like the real person?
No. It reproduces their writing style and relies on your real conversations, but nobody can predict a reaction for sure. Think of it as a realistic rehearsal, not a prediction.
How many conversations do I need to import?
One conversation with the person is enough, as long as it contains enough messages from them (a few dozen at least, a few hundred is better).
Does anyone read my messages?
No. Your conversations are encrypted on the server, only accessible from your account, and never used to train AI models.
SimuChat imitates a writing style, it doesn't read minds: the real person may react differently. For adults (18+) only; simulating a deceased person is not allowed.
