WHAT IS IT?
Capso is a native macOS screenshot and screen recording app, in the spirit of CleanShot X. A floating toolbar gathers the modes (area, window, fullscreen, scrolling, timer, OCR, recording), and annotation happens right after capture. Written in Swift/SwiftUI, it targets macOS 15+.
WHY IS IT INTERESTING?
- Unified capture: a CleanShot-style HUD with adjustable selection, aspect-ratio presets and a direct switch between screenshot and recording.
- Annotation and OCR: arrows, shapes, text, pixelation, numbered markers, plus on-screen text recognition with clipboard copy and translation.
- Polished recording: webcam picture-in-picture (4 shapes), pause/resume, countdown, and an editor with trimming, zoom suggestions, cursor smoothing and background styling.
- History and sharing: filterable capture library, pin-to-screen (click-through mode), cloud upload via Cloudflare R2.
- License to note: it's source-available under BSL 1.1, converting automatically to Apache 2.0 in April 2029. Not classic open source, worth keeping in mind.
USE CASES
- Document an interface with annotated captures and numbered markers.
- Record a tutorial or a demo with webcam picture-in-picture.
- Extract text from a screen region via OCR without reaching for another tool.
- Keep a searchable history of your captures instead of cluttering the desktop.
