# FlitKey > FlitKey is a fast, 100% offline, local-first text expander for Windows (10/11) and Linux (X11 & Wayland). Built with Python 3.10+ and PyQt6. ## Core Capabilities - **Instant Keyword Expansion**: Replaces typed trigger abbreviations (e.g. `;addr`, `/date`) with full text snippets or dynamic values across all desktop applications. - **Searchable Snippet Picker**: Global shortcut (`Alt` + `Space`) opens a fast fuzzy-search overlay window. - **Dynamic Placeholders**: Injects live date (`{{date}}`), time (`{{time}}`), timestamp (`{{datetime}}`), clipboard contents (`{{clipboard}}`), and controls cursor placement (`$|$` or `{{cursor}}`). - **Espanso & AutoHotkey Importers**: One-click batch conversion for `.yml`, `.ahk`, `.csv`, `.tsv`, and `.json` libraries. - **100% Offline & Private**: Zero telemetry, zero cloud calls, zero accounts. Data stored locally in `~/.config/flitkey/config.json` (Linux) / `%APPDATA%\flitkey\config.json` (Windows). ## Technical Specifications - **Language**: Python 3.10+ - **GUI Framework**: PyQt6 - **Platforms**: Windows 10/11 (64-bit), Linux (Debian/Ubuntu/Arch - X11 & Wayland) - **License**: MIT License (Open-Source) - **Current Version**: v2.4.1 ## Quick Installation Commands ```bash # Debian / Ubuntu (.deb) sudo apt update && sudo apt install python3 python3-pyqt6 xdotool xinput x11-xserver-utils sudo dpkg -i flitkey_2.4.1_amd64.deb flitkey # Windows Silent Install FlitKey-2.4.1.exe /VERYSILENT /SUPPRESSMSGBOXES ``` ## Key Documentation & Links - [FlitKey Homepage](https://flitkey.org/index.html): Overview, browser demo, and installer downloads. - [Full Technical AI Documentation](https://flitkey.org/llms-full.txt): Complete technical reference, code samples, API specs, and architecture. - [Official User Manual & Documentation](https://flitkey.org/docs.html): Setup guides for Debian `.deb`, Windows `.exe`, source code, and Manifest V3 Chrome Extension. - [Privacy Policy](https://flitkey.org/privacy.html): Zero-telemetry data notice, local storage paths, and clipboard handling. - [Refund Policy](https://flitkey.org/refund.html): 15-day money-back guarantee terms for FlitKey Pro. - [Compliance & Security](https://flitkey.org/compliance.html): GDPR, CCPA, HIPAA, and air-gapped endpoint security standards. - [Changelog & Release Notes](https://flitkey.org/changelog.html): Version release notes and update log. - [GitHub Repository](https://github.com/swarajnandedkar/FlitKey): Open-source source code and issue tracker.
