What Kaestral is

Kaestral is a free Windows desktop video editor that turns natural-language directions into edits on an editable timeline. Its multi-track editor handles video, audio, images, text, and Lottie tracks, with keyframes, transitions, color grading, and audio mixing. AI tools include word-level transcription and editing, filler and silence removal, word-synced captions, beat detection, and footage-frame analysis. Users can generate motion graphics and animated titles from text directions. Media imports by URL or drag and drop, while exports include H.264, H.265, ProRes, XMEML, FCPXML, and SRT, with 4K output listed. Kaestral supports MCP clients such as Claude Code, Cursor, and Claude Desktop, and exports project formats for Premiere Pro, DaVinci Resolve, and Final Cut. Files are processed and stored locally, no account is required for local editing, and the software is open source under GPLv3. Pro features are described as upcoming, and Max is planned.
