English and Simplified Chinese
- The app interface and release notes now follow your system language, with support for English and Simplified Chinese. Project content and captions remain unchanged.
- The installer now includes bilingual drag-and-drop instructions and an installation guide.
Interface and Experience
- Restored native menus and moved Report a Bug to the Help menu.
- Enlarged the Koma sidebar icon and added a black-and-gold PRO badge or a gray FREE badge based on the activated license.
Performance and Stability
- Kept one classic color per device model to reduce installer size. Existing projects map older colors to the retained option.
- Fixed main-thread isolation in Metal preview pause controls.
Recording Sources
- Record iPhone and iPad screens over USB, retaining device orientation, device audio, and the camera overlay.
- The camera overlay stays live across apps and full-screen spaces before recording. The installer also includes commands to reset screen recording and input monitoring permissions after an update.
Editor and Timeline
- The timeline shows tracks according to project content and expands editing space when captions, Auto Zoom, or static annotations are focused.
- Add captions manually, drag Auto Zoom segments, edit full-screen camera segments and static annotations, and adjust motion blur for Auto Zoom.
- The camera overlay scales along with Auto Zoom for more natural changes of focus.
Performance and Stability
- When the editor is paused, it redraws only when the image or settings change, greatly reducing CPU and GPU power use during idle editing.
- Recording setup uses a lightweight screen preview and isolates frequent state updates. Fixed a preview that could remain stuck loading after switching between foreground and background.
Installation
- The installer now includes a branded background and clear drag-and-drop instructions. Open it and drag Koma into Applications.
AI Editing and Captions
- When editing and generating captions together, structural edits are completed first. Captions are then generated from the final retained clips so they do not cross deleted content.
- Chinese AI captions consistently use Simplified Chinese characters and handle pauses within sentences and brief voiced segments more reliably.
Compatibility
- Fixed access to the current desktop wallpaper on macOS 27.
AI Captions
- Before generating captions, AI checks Koma’s persistent model directory and existing engine caches and verifies model usability to avoid duplicate downloads.
AI Editing
- When AI removes pauses or breaths, affected zooms are automatically shortened, split, or removed, with each adjustment listed in the preview.
Trial Information
- The Pro trial deadline now includes the exact minute and explicitly states Beijing time (UTC+8), avoiding the impression that access lasts throughout September 16.
Recording Setup
- The camera overlay can now be dragged reliably from both its center and edges.
- The first input monitoring permission request no longer adds an extra dialog. If permission is still missing, clicking again opens the relevant system settings directly.
Camera Overlay
- Drag the floating camera overlay directly from the camera image instead of having to grab the surrounding empty space.
- The camera overlay is temporarily hidden when update, permission, or other system dialogs open, so it no longer covers their buttons.
Limited-Time Pro Trial
- The recording workspace now shows both the Pro trial end date and the time remaining for early-bird pricing, keeping the two deadlines distinct.
- The limited-time Pro trial ends at September 16, 2026, 00:00 Beijing time (UTC+8). The permanently free edition remains available afterward.
Early-Bird Pricing
- Early-bird pricing will still be permanently withdrawn at October 1, 2026, 00:00 Beijing time (UTC+8). The sales countdown continues after the Pro trial ends.
- The license window uses consistent Pro trial wording and shows the exact time in Beijing time (UTC+8).
Limited-Time Access
- All Pro features are available without an email address or license until September 16, 2026, 00:00 Beijing time (UTC+8). The permanently free edition remains available afterward.
- Early-bird pricing now has a separate sales deadline. The CNY 99, 159, and 299 plans will be permanently withdrawn at October 1, 2026, 00:00 Beijing time (UTC+8).
License Status
- The license window now clearly shows when limited-time Pro access ends.
- If the early-bird catalog is temporarily unavailable, the purchase countdown is hidden rather than incorrectly using the Pro access deadline.
Workspace
- The app now opens to New Recording by default, with screen recording, input monitoring, microphone, and camera permission status in the top toolbar.
- Projects appear in a grid of 16:9 thumbnails with at least four columns. Creation time and duration are overlaid at the bottom of each thumbnail.
Windows and Details
- The main and editor windows use system translucency, and editor actions have moved into the native toolbar for a more consistent window layout.
- Recording modes, toggles, and project context menus now use native controls. Update publication times follow the system region and time zone.
Recording Workspace
- The main window uses a native sidebar for recent projects and new recordings, with clearer recording sources, permission status, and settings.
- If macOS does not show an input monitoring permission prompt, Koma explains why and provides a direct link to Input Monitoring settings.
Stability
- Fixed a UI state-update warning when quickly switching between recent projects and new recording.
- Fixed a UI state feedback loop when the floating camera preview followed window movement.
Editor and Timeline
- The editor now opens in its own window. Video thumbnails and audio waveforms share a track, with consistent heights, rulers, and drag feedback for caption and Auto Zoom tracks.
- Adjust Auto Zoom boundaries directly on the timeline, drag to zoom the visible range, view clip speed, and use Space, B, Delete, ⌘Z, and arrow keys for common operations.
- Canvas corners, camera aspect ratio and styling, settings hierarchy, and project management have been reorganized to make controls easier to find.
Captions and AI Editing
- Caption recognition uses full-transcript context to correct technical terms and can align timing to audio boundaries, reducing manual adjustments.
- Combine AI editing requirements, describe each one, and save local templates. External tools can read help as needed, preview changes, and verify project state before committing.
- Silence suggestions detect audio activity and report how conflicts with cuts, speed changes, captions, and Auto Zoom are handled.
Recording and Details
- The floating recording controls have a clearer native appearance. Fixed a case where the app could quit after the countdown finished.
- The default click effect is now a solid pulse in the app’s accent color. Timeline handles also show the appropriate resize or drag cursor.
Early-Bird Offer
- A server-time-synchronized early-bird countdown appears at the top of the recording workspace. Click it to see pricing and purchase options.
- The public beta and early-bird offer were set to end together at September 16, 2026, 00:00 Beijing time (UTC+8). Permanently free features remain available after the beta ends.
Menus and Feedback
- Unused system menus have been removed, leaving the Apple and Koma menus.
- The new Report a Bug… menu opens your mail app and automatically attaches diagnostic logs without project names, file paths, license keys, or device identifiers.
Public Beta
- Added installation-bound signed beta credentials, an explicit end date, and an offline grace period. The app falls back to its permanently free features when the beta ends.
- A new license window supports manually issued perpetual licenses and deactivation of the current device.
Free and Pro Features
- The app icon now uses a dark, three-layer window mark to reflect screen recording and layered editing.
- Free includes full recording and manual editing, with unlimited 1080p, 30 fps, Small File, H.264 exports carrying a Koma watermark.
- The Free watermark is now a more visible translucent logo and Koma wordmark, kept inside the recorded area even when canvas padding changes.
- A valid beta credential or perpetual license unlocks watermark-free export, 4K, 60 fps, HEVC, and the Agent CLI.
Updates
- Update checks and installer downloads now use Koma’s dedicated domain for a more reliable update entry point.
Updates
- When an update is available, the default browser opens the official download URL, avoiding sandbox restrictions on installers downloaded inside the app.
- Before installation, a notice explains that screen recording, input monitoring, microphone, and camera permissions may need to be granted again.
Export Settings
- Before export, file size is estimated from the edited duration and current encoding settings, making quality choices easier to compare.
- Duplicate headings and explanations have been removed. The preview is centered, and aspect ratio and source dimensions appear near their related settings.
- Frame rate, quality, and HEVC are now under Advanced settings, collapsed by default.
Updates
- The first launch after an upgrade shows the current version’s release notes, so you no longer need to visit the download page to find important changes.
- Check periodically at launch or manually from the app menu. After confirmation, the update can be downloaded, verified, and opened as a DMG.
Recording and Editing
- Adjust the white border width of the camera overlay before recording or while editing.
Export
- Export progress now shows elapsed and estimated remaining time, making long exports easier to follow.
- The export overlay uses the Koma app icon and clearly identifies preparation, rendering, and finalization.
New
- Record the screen, system audio, microphone, and camera as separate tracks.
- Virtual cursors, Auto Zoom, camera overlays, and non-destructive timeline editing are now available.
Editing and Export
- Set the project aspect ratio, canvas background, captions, and volume, and export MP4 with configurable H.264 or HEVC encoding.
- Preview and export share scene evaluation and the Metal rendering pipeline.
Distribution
- An ad-hoc signed Apple Silicon DMG, SHA-256 checksum, and public download URL are available.
