GPTAnon

GPTAnon is an anonymous AI chat tool that also lets you compare multiple models in a single window. You can message ChatGPT, Claude, Grok, Gemini, and many other models without leaving a server-side trail.

Privacy-first chat

Chats are stored locally in your browser rather than on a server. GPTAnon does not keep server history, log prompts, or run behavior analytics. To protect access on a shared device, you can set a PIN code to lock your conversations.

Side-by-side model comparison

GPTAnon helps you see how different models respond to the same prompt. Responses appear next to each other, making it easier to choose the right model for specific tasks.

• Compare outputs for coding, writing, brainstorming, and analysis
• Test prompts and learn how different models behave
• Keep drafts, work notes, and personal questions private

Who it’s for

GPTAnon is designed for people who prioritize confidentiality and prefer not to send sensitive prompts to services that store server-side histories.
