ChatBrawl: Multi-AI Chat Comparison

ChatBrawl is a browser extension for using multiple AI chat services in one interface. Write a question once, send it to your selected services, and read their answers side by side. Compare different approaches with less tab switching and repeated copying and pasting. Supported services include ChatGPT, DeepSeek, Claude, Gemini, and Doubao. See the full service list in the extension settings and choose a combination for writing, coding, learning, or research. Key features • Ask once, compare answers: Send the same question to multiple services through a shared composer, then compare their ideas, steps, and wording side by side. • Choose who receives each message: Use @ to select one or more services. Quote part of an answer to ask a focused follow-up question. • Upload files and images: Send your question with supporting material to services that support attachments. Compare document analysis or image interpretation. File types, sizes, and quantity limits depend on each service. • Reuse prompts: Save prompts, organize them with tags, search your library, and insert them with / shortcuts. Edit and preview Markdown, or browse featured prompts and add them to your own library. • Revisit conversations: Find, filter, and manage conversation history, then reopen an existing chat to continue your work. • Control supported native tools: Toggle web search, thinking, or deep research where integrated. Availability depends on the service and your account. • Customize your workspace: Add, switch, or close services, adjust the number shown per row, choose a light or dark theme, and use a Chinese or English interface. Ways to use ChatBrawl • Writing and translation: Compare drafts, phrasing, and tone to choose the right expression for your readers. • Coding and debugging: Review different code suggestions, implementation approaches, and explanations of a problem. • Learning and research: Explore concepts from multiple perspectives and compare explanations, research leads, and reasoning. • Documents and images: Share the same material with services that support uploads and compare their summaries or interpretations. Getting started 1. Install and open ChatBrawl, then select your AI services in Settings. 2. Sign in with your own accounts as required by each service. 3. Enter and send a question in the shared composer, or use @ to choose its recipients. 4. Read answers side by side, quote a passage for a follow-up, save a prompt, or reopen a conversation from history. Usage and data ChatBrawl works through the AI services' web interfaces and requires no API key configuration. Each service's login requirements, free usage limits, paid subscriptions, and regional restrictions still apply. Installing the extension does not unlock paid third-party features. Your personal prompts, interface settings, and history records saved by the extension are stored in your local browser. Questions and attachments you send are processed by the selected AI services under their own data and privacy policies. ChatBrawl is an independent tool and is not officially affiliated with the supported AI service providers. AI-generated answers still need to be checked.
