Built differently
Most AI assistants send your data to the cloud. Arc process it directly in your browser. No external infrastructure sits between you and your data.
- Runs on your your deviceAll processing happens locally inside your browser's secure sandbox. Prompts and page content never leave your device.
- Stays AnonymousNo logins, no identifiers, and no user profiles. Arc does not know who you are.
- You decideArc runs only when you activate it. No background monitoring. No silent scanning. No hidden automation.
- Nothing leavesArc does not sync, export, or transmit your content. If anything leaves your screen, it's because you chose it.
- Responds instantlyInference happens directly in your browser for fast, frictionless interactions without remote round trips.
- No hidden layersNo remote processing, no invisible infrastructure between you and your data.
AI, Where You Work
Arc stays embedded in your browser instead of becoming another destination. It works around your content, not the other way around.
Bring Highlights Together
Select content from different sections or pages and handle it in one interaction. Arc treats your highlights as part of the same request. No copying, no switching back and forth.
Right-Click, Instant Actions
Highlight text and turn it into emails, summaries, or posts. Rewrite, summarize, translate, or restructure directly from the page. No copy-paste. No switching tabs.
One AI, Everywhere
Arc stays available as you move between tabs and pages. Continue conversations across your session without starting from scratch.
What makes Arc different
Arc is built with a different architecture. While most AI assistants rely on remote servers, Arc runs directly inside your browser. Here's how that changes everything.
