PageGist

AI marginalia for the modern web. Summarize, explain, and explore any page instantly with Gemini Nano and other AI providers.

PageGist adds an AI side panel to Chrome that lets you summarize, explain, and have a conversation with any web page — without leaving the tab. Click the toolbar icon to open the panel. PageGist reads the current page and sends the content to your chosen AI provider, giving you instant, context-aware answers about what you're reading. BRING YOUR OWN KEY PageGist is built around a BYOK (bring your own key) model. Your data goes directly from your browser to the AI provider you choose — there are no PageGist servers in the middle. Currently supported providers: - Chrome's built-in Gemini Nano — works entirely on-device with no API key required. Available in Chrome 138+ with the Prompt API experimental flag enabled. - Groq — fast inference with a generous free tier. Sign up at console.groq.com and paste your key. - Anthropic — pay-as-you-go access to Claude models via the Anthropic console. OpenAI, Google AI Studio, OpenRouter, and Ollama (local) are coming in v0.2. FEATURES - Instant summaries — get the gist of any article, thread, documentation page, or report in seconds. - Conversational Q&A — ask follow-up questions and explore the page content in a natural dialogue. - Per-URL history — conversations are saved per page in local browser storage, so you can pick up where you left off. - Token and cost counter — an optional footer shows estimated token usage and cost per session. - Configurable page reading limit — control how much of the page is sent to the model (500 to 30,000 tokens). - Data export and clear — export all your data as JSON, or wipe your conversation history at any time from the settings page. PRIVACY PageGist has no backend server. All processing happens in your browser and through the AI provider you select. API keys are obfuscated in local storage so they are not visible at a glance in Chrome DevTools. Telemetry is off by default. REQUIREMENTS Chrome 138 or later. For Gemini Nano, the Prompt API experimental flag must be enabled at chrome://flags/#prompt-api-for-gemini-nano. For cloud providers, you will need your own API key from the respective provider.
