How we score
What makes the best AI browser assistant
We weight capabilities that separate a chat sidebar from a true work assistant.
Context depth
Can it read multiple tabs, groups, files, and screenshots—not just the active page?
Execution
Does it click, fill forms, and finish multi-step flows—or only suggest steps?
Parallel work
Can automation run in a background lane while you stay on your main task?
Model access
Are leading models included free, or gated behind subscriptions and API keys?
Platform fit
macOS, Windows, and import path from Chrome/Edge/Safari without friction.
