OmniChat — Ask Every AI at Once

Ask ChatGPT, Claude, Gemini, DeepSeek, Grok, and custom AI agents at the same time from one Chrome side panel.

OmniChat is a Chrome side-panel extension for asking the same prompt across multiple AI chat tools at once, then comparing the responses in one place. The purpose is simple: simultaneous conversation and comparison. You type one prompt, choose the AI tools you want to use, and OmniChat sends that prompt to the selected chat pages so you can compare answers, reasoning styles, speed, and usefulness side by side. OmniChat does not modify AI models, change provider behavior, bypass provider rules, or interfere with any AI platform. It does not run code on provider servers and does not claim partnership with any AI service. The extension only automates the user-facing browser workflow you choose: placing your prompt into selected chat pages, submitting it, and showing the responses back to you for comparison. Key features: - Broadcast one prompt to multiple AI chat providers. - Continue follow-up questions in the same provider conversations. - Compare answers in a side-panel transcript. - Open split-screen view to compare providers side by side. - Save local conversation history and reopen previous conversations. - Add custom HTTPS chat agents with runtime permission prompts. Privacy: OmniChat is local-first. It does not operate a backend server, does not sell user data, does not use analytics, and does not send data to servers controlled by this project. Prompt text is sent only to the AI providers selected by the user. Conversation history and settings are stored locally using Chrome extension storage. You must be signed in to the AI provider websites in your own Chrome profile. OmniChat does not collect, store, or transmit provider passwords or API keys.
