What is a chat mockup?
A chat mockup is a realistic-looking screenshot of a messaging conversation that never actually happened. It is a design asset, in the same family as a device frame or a browser window mockup: something you drop into a video, a slide, a thumbnail or a story to show a conversation instead of describing it.
People reach for them constantly. A creator staging the opening line of a story. A designer showing what a notification flow looks like in context. A teacher writing a dialogue exercise. A founder putting a customer conversation on a pitch slide without publishing anyone's private messages. In every one of those cases, the alternative is either a real screenshot (a privacy problem) or a grey box with placeholder text (a clarity problem).
Why ChatMock is different
It runs entirely in your browser. No upload, no account, no server rendering your conversations. The page keeps working after you disconnect from the internet, which is the easiest way to verify that claim yourself.
No watermark, and no paywall on the basics. The whole point of a mockup is that it looks real; a logo stamped across it defeats the purpose. PNG export at 1x, 2x and 3x is free.
The details are correct. Bubble radius, the way consecutive messages lose their tail, the exact shade of blue on a read receipt, the cap on bubble width. These are the things that betray a fake screenshot, and they are different on every platform — which is why we build one platform properly at a time rather than shipping twelve approximations.
Using mockups responsibly
A mockup is a creative tool, and like any creative tool it depends on intent. Illustrating, parodying, teaching and designing are all fine. Using a fabricated conversation to deceive someone, to harass or impersonate a person, or to manufacture evidence is not — and we do not want that traffic.
