Why Proton-T?

🦀

Powered by Rust

Zero dependencies. <10ms execution time. Noticeably faster than Python equivalents, ensuring your shell remains extremely responsive.

🧠

Frecency Algorithm

Balances frequency (most used) with recency (recently used). Projects you haven't touched in a week gracefully decay in rank.

🎯

Intent Engine

Speak naturally to your shell. Typing t project or t backend instantly maps your intent to specific folder types.

🔍

Fallback Discovery

Never visited a folder? Proton-T automatically scans your roots breadth-first to find it, booking it for future instant access.

🐚

Universal Shells

Native support for Bash, Zsh, Fish, and PowerShell. Proton-T speaks every major shell language fluently on Linux, macOS, and Windows.

🛡️

Privacy First

No cloud. No telemetry. Your directory database is stored 100% locally on your machine. Your workflow history is nobody's business but yours.
