CodeKitHubWhat Is This Tool?
Reddit Chat Simulator recreates the real Reddit chat interface — a contact header with avatar, username and online status, and a scrolling list of message bubbles in Reddit's dark chrome with an orange accent — so you can export it as a shareable mockup image.
It must never be used to fabricate fraudulent evidence, harass or defame someone, or impersonate a real person's actual messages — doing so may be illegal depending on your jurisdiction.
Everything is generated locally in your browser using the HTML Canvas API; nothing is ever uploaded to a server.
Why Use It?
- 100% local rendering — your content never touches a server.

- Type each message's text and timestamp.

Responsible use
This generator exists to make it easy to create clearly fictional mockup images for humor, storytelling and design work. If you share an image made with this tool, consider adding context so viewers understand it is not a real conversation.
Frequently Asked Questions
Is it legal or ethical to use this tool?
The tool itself is legal to use for entertainment, mockups, presentations and design work. What is not legal or ethical is using the generated image to deceive someone. Please only use this for clearly fictional or illustrative purposes.
Does the tool upload my content anywhere?
No. Everything you type stays in your browser's memory and is drawn directly onto a canvas element with JavaScript. The PNG is generated and downloaded on your device — nothing is ever sent to a server.
Can I upload a real photo as the contact avatar?
Yes — click "Upload photo" to use a real image for the avatar circle, or leave it as a colored circle with initials generated automatically.
How many messages can I add?
There's no hard limit — add as many message bubbles as you like, alternating between "them" and "me", and the canvas scrolls to fit the full conversation.
