What is it?

Caplo is a macOS screen recording app built with Swift and SwiftUI on top of ScreenCaptureKit. It records the full screen, a custom area or a single window, and can capture camera, microphone and system audio at the same time. After recording, the clip opens in an editor where zoom focus is generated automatically from clicks and pointer movement, and can be adjusted on the timeline.

The editor covers cursor smoothing and click effects, canvas layout with background, padding, corner radius, shadow and cropping, plus overlays such as masks, text, title cards and watermarks. Keystrokes can be shown as keycaps when input monitoring is enabled. Subtitles are transcribed locally with the system speech recognizer and can be edited line by line, and audio tools include noise reduction, echo cancellation and silence removal.

Exports are available as H.264 or HEVC in MP4, ProRes 422 in MOV, or GIF, up to 4K. The interface supports Simplified Chinese and English. The project requires macOS 15 or later and Xcode 16 to build from source.
