🧭
Autonomous web agent
Plan → observe → act → verify across any site. Navigates, clicks, types, fills forms and extracts data to finish your goal.
Hyperion
Security & privacy-first · Chrome extension
Autonomous agents
for the
agentic web
State a goal — Hyperion plans it and carries it out across any website, then gives you a full AI chat workspace for runnable code, documents and diagrams. Untrusted code is sandboxed and your data never leaves your device.
See it in action
A real run: stating a goal, watching Hyperion plan and act across the web, and using the chat + artifacts workspace.
One extension, two superpowers
An autonomous web agent and a ChatGPT-class assistant — side by side.
💬
Chat + artifacts
Documents, code, diagrams, charts and live apps render as interactive artifacts — edit them in an auto-saving WYSIWYG canvas or a syntax-highlighted editor, then export to PNG or PDF.
▶️
Code execution
Run real code right in your browser: Python (Pyodide — numpy, pandas & matplotlib on demand), SQL (in-browser SQLite), and JavaScript / React — no server, no setup.
📊
Data visualization
Mermaid diagrams, interactive charts (Chart.js, D3, Recharts), matplotlib plots and SVG — generated from a prompt and rendered live. Point a chart at a URL data source and refresh it.
📦
React & any npm library
React/JSX artifacts can import any npm package — d3,
three.js, framer-motion, chart.js and more — integrity-checked and
bundled in your browser, never from a CDN.
🛡️
Sandboxed by design
All generated code runs in an isolated, opaque-origin sandbox with no network and no access to your keys or the page. How it works →
🔒
Privacy-first
Keys, chats, memory and tasks stay on your device (AES-GCM encrypted). No telemetry, no tracking, no Hyperion server.
🔌
Multi-provider
Bring your own model: OpenAI, Anthropic Claude, GitHub Copilot or GitHub Models — pick the brain, reasoning level and context window.
🔎
Deep research & search
Multi-step, sourced research and quick web search that cite their findings — grounded, not guessed.
📚
Sources & semantic RAG
Drop in PDFs, DOCX or text and get cited answers — with optional on-device embedding-based semantic retrieval.
✋
Safety checkpoints
Careful / Balanced / Autonomous modes. It pauses for approval before payments, submissions and other sensitive actions.
🗓️
Memory & scheduling
Remembers facts across chats and runs recurring tasks on a cron schedule — all stored locally on your device.
🧩
Tools & MCP
Connect remote Model Context Protocol servers, query GitHub, and pull live Wikipedia, news and stock data — straight from chat.
State a goal. It does the rest.
Hyperion lives in the Chrome side panel. Type what you want — “find the cheapest mechanical keyboard under $100”, “extract this table”, “summarize the top AI stories” — and it plans the steps and carries them out, pausing for your approval when it matters.
- Multi-tab workflows with vision fallback
- Completion checks before it calls a task done
- Undo, pause and resume any run
- Everything runs in your browser — no Hyperion server
Take a tour
Every tab of the Hyperion side panel — from stating a goal to managing memory and schedules.

Security & privacy by design
Untrusted code is isolated in an opaque-origin sandbox with no network, and every third-party package is integrity-checked. Your keys, chats, tasks and memory stay in your browser (AES-GCM encrypted) — no telemetry, no tracking, no Hyperion server.
