Skim

Skim is a minimalistic, open-source AI email client designed for Windows users seeking a lightweight and privacy-focused email experience. Built with a native Rust core via Tauri 2, it boasts a tiny installer (~5 MB), rapid startup times, and instant full-text search. Unlike traditional email clients, Skim strips away unnecessary features like calendars and rules, reducing cognitive load and streamlining email management. Its open-source nature ensures transparency and customization, while local-first architecture guarantees offline access and zero telemetry. Users can leverage their own AI keys from providers like Anthropic or OpenRouter to draft replies in their voice and query their mailbox efficiently, making it ideal for privacy-conscious users and those wanting AI assistance without bloat.
