Espanso

Espanso is a privacy-first, cross-platform text expander that automates repetitive typing with simple keyword triggers.

Espanso is a robust, open-source text expander designed for system-wide productivity across Windows, macOS, and Linux. It operates on a privacy-first principle: all data remains 100% local with no tracking, a key advantage. Users define 'matches' (substitution rules) in simple YAML configuration files, linking a short trigger (e.g., `:sig`) to a long replacement (e.g., a full email signature). Written in Rust, it’s fast and reliable, handling complex tasks like custom scripts, shell commands, and date expansion. This tool eliminates repetitive typing, making it essential for customer support, coding, and general office work.
