Describe what you want in plain English. OpenBrowser clicks, types, scrapes, fills forms, and researches — using your own AI key with no middleman.
How it works
Download the ZIP, load it in Chrome as an unpacked extension. No account. No signup. No credit card.
Paste a key from Anthropic, OpenAI, Groq, or any of 12 providers. Or run Ollama locally — completely free, completely offline.
Type what you want. Watch the AI navigate, click, extract, and complete — step by step, with a live streaming transcript.
Features
Every feature ships in the extension itself — no cloud dashboard, no plugin marketplace, no upsell.
Answers appear token by token the moment the model starts generating. Watch the agent think in real time — no spinners, no waiting.
Dictate instructions with the mic button. Live interim transcription via the Web Speech API — no extra setup, works offline.
Ctrl+Shift+P opens a floating command overlay directly on the active webpage — no panel needed.
Semantic field matching — "first name", "given name", "prénom" all resolve correctly. Handles React and Vue controlled inputs.
Scrape and compare multiple open tabs simultaneously. Outputs a structured comparison table from any set of pages.
The AI can create, read, and delete files in an IndexedDB store. A "Files" tab shows a tree view with download support. Ask it to write code and save it — it will.
Use the memorize tool to store facts across sessions. A visual Memory Dashboard lets you edit or delete anything stored — full transparency, full control.
Save tasks as macros and schedule them to run every 15 min, hourly, or daily.
Flowcharts, ER diagrams, and Gantt charts render live inline — no copy-paste to a diagram tool.
Dark, Light, and Custom accent color — full CSS variable swap, persisted per session.

Keyboard-First
Built for power users who don't want to reach for the mouse.
