Pie · Open-Source AI Agent for Browser & Tabs

Open-source AI browser agent. Bring your own Claude / ChatGPT / Gemini key — no backend, no telemetry, no proxy. 8 providers.

Pie is an open-source AI browser agent for Chrome. Type a task in natural language — "summarize this page", "close inactive tabs", "fill out this form using my saved data" — and Pie's AI agent plans the steps and executes them across your browser tabs. ✨ What makes Pie different: 🔑 BYOK (BRING YOUR OWN KEY) — No subscription, no Pie backend, no telemetry, no proxy. Your API key is encrypted locally with AES-GCM and only ever sent as the Authorization header on direct calls to your chosen provider. 🤖 NATIVE TOOL CALLING — Not a prompt-glued wrapper. Pie uses Anthropic tool_use blocks and OpenAI function_calling to drive a typed tool registry: DOM actions, cross-tab orchestration, page content extraction. 🎯 SKILLS — Save any prompt as a reusable skill with a scoped tool whitelist. Run with /skill_name. The AI agent can author its own skills too, so workflows the model just figured out can be replayed next session. ⌨️ CANVAS EDITOR SUPPORT — Pie supports Chrome DevTools Protocol keyboard injection (opt-in), so it works with canvas-based editors like Google Docs, Notion, and Lark Docs where standard DOM events fail. 🌐 WEB SEARCH — Pie's agent can search the web for current info via Tavily (BYOK — bring your own Tavily key, 1,000 free queries / month). Search results are sandboxed in untrusted markers and the agent auto-drills into the top URLs as pinned tabs, then synthesizes with real citations. Knowledge questions, fact-checks, "research X for me" — Pie figures out when to search and when to use the tab you're on. 📑 MULTI-SESSION — Conversations survive Service Worker restarts. Archived sessions evict on storage pressure (LRU + 30-day delete). Pin tabs per session so Pie's agent stays scoped to your task. 🌐 SIDE PANEL, NOT POPUP — Pie lives in Chrome's side panel and stays open while you browse. Chat, run AI tasks, manage tabs without losing context. 🔒 PRIVACY-FIRST — No Pie servers. No analytics. No third parties. Page content sent to the LLM is wrapped in <untrusted_*> markers to defeat prompt-injection attempts from page DOM.
