OpenScreen

OpenScreen is a desktop application for recording your screen and editing the footage into polished demos and walkthroughs. It captures video using native system APIs (ScreenCaptureKit on macOS, Windows Graphics Capture on Windows, PipeWire on Linux) and includes on-device AI-powered captions, automatic cursor styling, and GPU-accelerated export. The project describes itself as the open-source entry in the category Screen Studio defined, with no paywall or watermarks.

Features include window or full-screen recording, webcam overlays, auto and manual zooms, custom cursor effects, editable transcripts, an AI editing assistant (bring your own API key), background customization, annotations, and export to MP4 or GIF. According to the source, the application was built using Claude for code assistance. It supports multiple languages and is available for personal and commercial use under the MIT license.
