Pie · Open Source Ai Agen

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. Apache 2.0 licensed
