GudChat

Chat with any webpage using local or cloud AI. Fill forms, explain content, summarize pages, and more. GudChat is an AI-powered browser side panel that lets you chat with any AI model about the page you're browsing. Use your own API keys or local models — no subscription, no markup, no data collection.

What GudChat does:

Opens as a side panel next to any webpage (Ctrl+Shift+G / Alt+Shift+G). Sends page content as context to your chosen AI model. Summarizes pages, explains selected text, helps fill forms, and extracts data. Select text on any page for instant actions: Explain, Summarize, Rewrite, Shorten, Expand, Simplify, Reply. Beautiful markdown rendering with syntax-highlighted code blocks, tables, blockquotes, and clickable links. Upload or paste images for vision-capable models (GPT-4o, Claude, Gemini, LLaVA) Stop generation mid-response with one click

Slash commands: /search — Search the web and get AI-summarized answers with sources /compare — Send the same prompt to multiple models side by side /translate — Translate selected text or page content between languages /export — Save conversations as Markdown or JSON /prompts — Open your prompt template library

Custom prompt templates: Create your own reusable prompts beyond the built-in actions. "Translate to Spanish," "Write unit tests," "Convert to bullet points" — save them to your library and use them with one click.

Model comparison: Compare responses from different models side by side. Select 2 or more providers, send a prompt, and see all responses stream in parallel. Great for evaluating which model works best for your use case.
