Split-screen multi-AI comparison workspace. No API keys, no data collection. ChatDuel is a split-screen workspace for comparing multiple AI web apps. Ask once, send the same prompt to supported official AI websites, compare responses side by side, and organize consensus, disagreements, and next steps without API keys. ChatDuel works with the official AI pages you are already logged into. It does not provide AI accounts, does not call LLM APIs, and does not bypass login, subscription, rate limit, regional availability, or content rules of any supported AI service. Key features: Ask once and send to multiple AI services Compare ChatGPT, Gemini, Doubao, DeepSeek, and Claude responses in one workspace Forward one AI answer to another AI for review Summarize shared opinions, disagreements, and final recommendations Attach supported files and images where the target AI website allows it (DeepSeek automatically switches to vision mode for image uploads) Keep local records for review, copying, Markdown export, summary, and transfer Restore official chat links and continue on the original AI websites Interface language support for Chinese, English, French, German, Swedish, Norwegian, Dutch, Japanese, and Korean Privacy: ChatDuel does not collect or upload your prompts, AI responses, attachments, account credentials, cookies, tokens, sessions, or browsing history to ChatDuel servers. Local records stay on your device. The extension only requests a non-executable configuration endpoint from chatduel.ifeeling.app to keep page selectors working when supported official AI websites change. This configuration is not remote code and is not executed by the extension. ChatDuel is open source.
