Proton Browser: Privacy Is Only Half the Story
Proton keeps your data private — but there is no Proton Browser for Windows or macOS yet, and its tools stop at blocking. Tabbit is an AI-native browser that protects your focus and gets work done.
Free AI browser for Windows & Mac.
What is Proton Browser?
Proton — the company behind Proton Mail and Proton VPN — ships a privacy browser on two platforms and still recommends third-party browsers everywhere else.
Proton Browser for Android
A lightweight, Firefox-based browser focused on ad blocking, tracker blocking, and privacy protection on mobile.
Proton Browser for Linux
An early-stage desktop browser based on Tor Browser, designed for hardened privacy on Linux.
No Windows / macOS version yet
Proton officially recommends Firefox, Brave, and Tor Browser for Windows and macOS users who want privacy-first browsing.
Where Proton Browser stops
If you only need private browsing, Proton’s approach is solid. But a browser that only blocks trackers can’t read a 50-page report, fill a form across systems, or run your research while you work.
No agentic execution
Proton Browser blocks trackers but cannot click buttons, fill forms, or chain tasks across websites.
No Windows or macOS release
The flagship desktop platforms get a recommendation list, not a Proton-built browser.
No AI productivity layer
No omnibox context, no script skills, no workspaces or vertical tabs for heavy research workflows.
Privacy first, productivity later
There is no built-in AI assistant that reads the page you are on and takes action.
Tabbit: the AI browser that actually does the work
Tabbit keeps the privacy essentials you expect — and adds an agentic layer that turns your browser into a teammate.
Agent Mode that finishes tasks
Tell Tabbit what you need in plain language. It reads pages, fills forms, operates across sites, and returns a structured result while you keep working.
Omnibox with @ context
Press @ to feed live tabs, tab groups, screenshots, bookmarks, and local files into the AI. No more copy-paste.
Skills & script shortcuts
Save prompt recipes as /commands and generate one-sentence automation scripts. Discover and share workflows in the Skills Marketplace.
Vertical tabs & workspaces
Auto-grouped workspaces keep research projects, work tasks, and personal browsing in separate, focused spaces.
Top AI models, free
International build: Gemini, GPT, Claude. China build: DeepSeek, GLM, Kimi, Qwen, Doubao, MiniMax, LongCat.
Knowledge-base bookmarks
Save pages as searchable knowledge with full-text retention, and ask the AI to find answers inside your bookmarks.

Two browsers, three real tasks

Not possible — the browser only protects.
Daily task delegation
