CodeKitHubWhat Is This Tool?
Gemini Conversation Generator recreates Google Gemini's interface — its dark theme, Google-blue accent color and sparkle-style assistant avatar — so you can type your own conversation and export it as a shareable image.
It must never be used to fabricate fraudulent evidence, harass or defame someone, or impersonate a real person's actual posts — doing so may be illegal depending on your jurisdiction.
Everything is generated locally in your browser; nothing is ever uploaded to a server.
Why Use It?
- You're writing a tutorial about using Gemini inside Google Workspace and want a clean dark-mode screenshot showing a specific prompt and answer, without needing to run and re-screenshot a live session for every revision.
- You're making a joke or meme about Gemini's answers and want the dark theme and sparkle-mark avatar to be instantly recognizable rather than a generic dark chat box.
- You're prototyping an Android or Workspace feature that surfaces a Gemini-style assistant and want a quick, editable mockup to show teammates before real integration work starts.
- You're building comparison slides across different AI assistants and want the Gemini example to visually match the dark theme people actually see in the product.
- You want to iterate fast — swap a line, reorder turns, change an avatar — and download a clean, high-resolution PNG with no account or watermark in the way.
How to Use
- Optionally upload custom avatars for you and the assistant.
- Add turns to the conversation, choosing 'User' or 'Assistant' for each.
- Type the message text for each turn.
- Watch the live dark-mode preview update, then click "Download PNG" to save the image.
Example
Input
Message 1 (User): "Can you explain what a black hole is in simple terms?" · Message 2 (Assistant): "Sure! A black hole is a region of space where gravity is so strong that nothing — not even light — can escape it."Output
A PNG showing an alternating conversation styled like Gemini's real dark interface: a gray user avatar and a sparkle-mark Gemini avatar, each with its own label and wrapped message text.The image renders instantly in the live preview and downloads with a single click — no waiting, no server round-trip.
What you can customize
- User and assistant avatars (upload your own photo or use the default).
- Any number of conversation turns, alternating User and Assistant.
- The full text content of each message.
- Layout details matching Gemini's real dark interface and Google-blue accent color.
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 Gemini 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 rendered directly in the page. The PNG is generated and downloaded on your device — nothing is ever sent to a server.
Why is the preview dark by default?
Gemini's default web and app theme is dark, so this generator matches that look out of the box for the most recognizable mockup.
Can I upload a real photo as the avatar?
Yes, you can upload a custom photo for both the user and assistant avatar, or leave the defaults in place.
Should I use this or one of the other AI chat mockup generators?
If your scenario is about Google Workspace, Android or Google Search integration, use this Gemini generator. If it's about coding or writing help in a minimal warm UI, use the Claude generator; for a search-answer-with-citations look, use the Perplexity generator; for Microsoft 365 or Windows contexts, use the Copilot generator. Match the tool to the platform your audience will recognize.
Is there a limit on how many conversation turns I can add?
No hard limit — add as many User/Assistant turns as you need, and the live dark-mode preview grows to fit the full conversation before you export it.
Can I reorder or remove a turn after adding it?
Yes — each turn can be reordered or removed individually, with the preview updating instantly so you can check the flow before downloading.
What resolution does the downloaded PNG use?
The export is rendered at a resolution sized to fit your full conversation, sharp enough for a slide deck, tutorial, or blog post rather than a small thumbnail.
Does it support markdown formatting like bold text or code blocks in the messages?
No — message text renders as plain text, matching the tool's focus on quick conversation mockups rather than full markdown rendering.
Is this affiliated with Google?
No. This is an independent fan-made mockup tool for entertainment and design purposes only. It is not affiliated with, endorsed by, or connected to Google in any way.
