v 0.7
Feature Privacy

Redaction, on-device: mask sensitive content

Drag a rectangle over anything sensitive — an API key, an email, customer data — and cover, blur, or pixelate it for a span of the timeline. On-device detection can find emails, tokens, and card numbers for you and stage them as suggested masks to confirm. Nothing leaves your Mac.

  • Cover, blur, or pixelate any region across a time range
  • Redacted everywhere: preview, MP4/GIF export, and MCP frame grabs
  • On-device auto-detect stages suggested masks for review
v 0.6
Feature Audio

Cleaner takes: silence removal and voiceover

Detect dead air in your narration and cut it in one step — adaptive to the take's own noise floor, and one undo to revert. Then park the playhead and record a voiceover over the edited take, watch-and-narrate style, on a dedicated timeline lane.

  • Adaptive dead-air detection applied as ordinary, editable cuts
  • Record narration over the finished edit — multiple takes, one lane
  • Everything stays inspectable and reversible on the timeline
v 0.5
Feature Improvement

Camera, backdrops, and sound

A wide or bubble webcam self-view you can toggle live or after the fact, backgrounds that derive their gradient from the recording's own colors, audible click sounds, and pitch-preserved audio retiming. Edits autosave as you go, and the app updates itself.

  • Webcam self-view — bubble or wide 16:10, toggleable anytime
  • Adaptive backgrounds sampled from the recording's palette
  • Click sounds, pitch-preserved retime, autosave, and auto-updates
v 0.4
Feature MCP

An agent can drive a live editing session

Playback now ships an MCP server. Point any MCP client at playback-mcp and an agent can control a running session end to end — list windows, start a recording, drop a zoom on the moment that matters, caption a step, and export.

  • 28 MCP tools mapping 1:1 to editor commands
  • Bridges to the live app over a local Unix socket
  • Async export returns a job id you poll for progress
v 0.3
Feature

Cursor-following auto-zoom

The analyzer reads the recorded cursor track and places smooth, cursor-following zooms on the moments that matter — so you get a punchy, close-up demo without keyframing a thing.

  • Automatic zoom placement from cursor movement
  • Adjustable easing, hold, and scale per zoom
  • Override or delete any zoom on the timeline
v 0.2
Feature Improvement

Backgrounds, captions, and click effects

Float the recording on a gradient backdrop, smooth the cursor, and add click ripples. On-device speech turns your narration into captions — no upload, no transcription service.

  • Gradient and solid backgrounds with padding controls
  • Smoothed cursor with configurable click effects
  • Captions generated on-device from your audio
v 0.1
Feature Performance

MP4 and GIF export on Metal

A ground-up render path: a Metal compositor with AVFoundation and VideoToolbox export. Preview is instant and export is hardware-accelerated — no cloud round-trip, no watermark.

  • Hardware-accelerated H.264 / HEVC export
  • Optimized GIF export for changelogs and PRs
  • GPU compositing keeps preview at full frame rate
v 0.0
Feature Fix

Native capture with ScreenCaptureKit

The first build. Capture a screen or a single window with ScreenCaptureKit, record system and mic audio, and keep a precise cursor track alongside the video for everything downstream.

  • Screen, window, and audio capture via ScreenCaptureKit
  • Cursor sidecar recorded in lockstep with the clip
  • Fixed a race when stopping a recording mid-frame
