About

sleek is an open-source (FOSS) todo manager based on the todo.txt syntax, available for macOS as well as Windows and Linux. It is stripped down to the most necessary features, with a clean and simple interface designed to help you focus on getting things done. All classic todo.txt attributes are supported and enhanced by additional features.

Creating todos is straightforward. Tag-based filtering, highly customisable grouping, and smart full-text search allow for rapid information retrieval. Completed todos can be hidden or archived into separate done.txt files. sleek continuously scans todo.txt files for changes, which facilitates easy integration with other todo.txt apps.

On a Mac, sleek can be obtained from the Apple Mac App Store or installed via Homebrew with the command brew install --cask sleek-app. The project is offered in several languages, and more detailed information is available in the sleek wiki.
