Custom Chat Generator and Fake Text Conversation Maker

Build a custom fake chat and preview a text conversation before exporting

A custom chat generator is a controlled mockup of a text conversation built for previews and presentations, not a real message thread. With this simulator you set the contact, the avatar, the bubble colors, and the theme yourself, add text and photo bubbles and day dividers, then export a chat-style screenshot directly in the browser.

This custom chat simulator is a fake text conversation maker for previews: set your own contact, avatar, and bubble colors, add messages and photos, then export the mockup.

Most chat simulators lock you into one app's exact colors and logo. This one does the opposite: you choose the outgoing and incoming bubble colors from curated swatches or any custom hex, upload your own avatar, write the contact name and header subtitle, and switch between a light or dark theme. That makes it the right tool when you need a chat screenshot that does not visually belong to WhatsApp, iMessage, Messenger, or any other specific app — useful for product concepts, UI design reviews, video scripts, or storytelling where the messaging app itself should stay generic. Because the whole custom chat generator runs in your browser, nothing is uploaded to a server and no account from any messaging app is involved. You add blocks one at a time, set who is on the left and who is on the right, control the read receipt per message, drop in photo bubbles with captions, and insert day dividers to structure a longer conversation. When the mockup looks right, you export it as an image for slides, app concepts, tutorials, or social content. The goal is honest previewing and storytelling, not deception. A fake chat made here is a design asset, the same way a wireframe or a stock photo is. It should never be used to impersonate a real person, fabricate evidence, or mislead anyone into thinking a conversation actually happened.

How to make a custom fake chat

Build a believable text conversation in a few steps, entirely in your browser.

1. 1

   Set the header: type the contact name, write a header subtitle like "Online", upload an avatar, and pick the light or dark theme.

2. 2

   Choose your outgoing and incoming bubble colors from the curated swatches, or pick a custom hex for an exact match.

3. 3

   Add your conversation blocks one at a time — text messages, photos, and day dividers.

4. 4

   Choose a sender for each block so the bubbles land on the left or the right side of the chat, and set the timestamp and read receipt.

5. 5

   Preview the chat-style screen and export your custom fake chat screenshot as an image.

How to tell if a chat screenshot is fake

Mockup tools like this one make chat screenshots easy to fabricate, so it pays to know the tells. If you receive a chat screenshot and need to judge whether it is genuine, look for these signs before trusting it.

• A messaging app style that does not match any real app you recognize, or bubble colors, fonts, and icons that feel generic rather than tied to a specific product.

• Timestamps that do not add up — bubbles out of chronological order, identical times on a long back-and-forth, or a header subtitle that contradicts the message times.

• Inconsistent read receipts: a delivered or seen mark on a message the timeline shows was never realistically opened.

• A visible watermark, missing status bar, or a crop that conveniently hides the header, the keyboard, or the surrounding phone interface.

None of these checks are proof on their own. The only reliable confirmation is the original conversation on the actual device or an export from the real app itself. Treat any standalone screenshot, including one made here, as unverified.

What you can put in a custom conversation

This is more than a fake text message generator — each block type recreates a different part of a real chat so the mockup looks complete, whatever app style you have in mind.

• Text bubbles with a read receipt and timestamp, for the core back-and-forth of any fake conversation, in colors you choose.

• Photo blocks with optional captions and overlaid time and receipt, for a media-rich chat.

• Day dividers to break a longer conversation into a realistic timeline, like "Today" or "Yesterday".

Common mistakes to avoid

• Putting a read receipt on every message — real chats mix sent, delivered, and seen states.

• Using identical timestamps on a long conversation, which instantly looks pasted rather than recorded.

• Picking outgoing and incoming colors that are too close to each other, making the two sides of the conversation hard to tell apart.

• Using the mockup to impersonate someone or fabricate evidence — keep it to honest previews, demos, and storytelling.
