ChatBrawl is a free multi-AI chat comparison tool for people who use ChatGPT, Claude, DeepSeek, Gemini, Grok and other AI services every day. Ask once and get responses from multiple models side by side, so you can compare reasoning, quality, factual coverage and writing style faster. Key features: 1. Multi-AI response comparison Send one prompt to multiple official AI sites and review the answers in one workspace. 2. File and image conversations Upload documents, materials, screenshots and images, then compare how different models understand the same context. 3. Search and reasoning mode switching Use supported native search, reasoning, thinking and deep search modes from each official AI site. 4. @ follow-ups for one model Start with a multi-model comparison, then mention a specific AI with @ to continue a focused conversation. 5. Unified conversation management Search, review and clean up local conversation records, and manage history stored in official AI accounts. ChatBrawl requires no API key. It keeps each official AI site's login state, theme, file upload, search, reasoning and other native capabilities. It supports 18 mainstream AI sites and works with Chrome, Edge and Firefox. ⚠ Instructions for use: Please ensure that your network can access the relevant official website, and the effect is best after logging in. 1.0.0 1.
