Every feature, honed for teaching

From recording to editing, every part is designed to help you "teach a lesson clearly and ship the video fast."

Recording

Operate as you teach, and get it right in one take.

Record your whole screen or select a single area, up to 4K 60fps. Pause and resume whenever you like.

Pen, arrow, line, rectangle, and highlighter—whatever you point at gets marked, composited into the recording in real time.

Magnify the part you are explaining in one tap. Lock it in place or let it follow your cursor so details stay sharp.

Circle or rounded face window, with mirror, digital zoom, and border styles. Drag to move and resize freely.

Draw a ripple where you click and dim everything around the cursor with a spotlight to guide your students’ eyes.

Lay down a whiteboard as scratch paper; show keystrokes live for demoing shortcuts; count down before recording starts.

Produce a clean final video without learning professional software.

Built-in whisper.cpp transcribes English and Chinese speech offline—nothing is uploaded. Even the free version can try the workflow.

Delete a wrong sentence in the subtitle script and the matching clip is trimmed automatically—edit video like editing a document.

Automatically flag silences, filler words (um/uh/you know), and repeated retakes, then cut them in one click once you confirm.

Remove background hum and keyboard noise so your voice comes through clearly.

Add title intros, text and image stickers, and looping background music with automatic fade in and out.

Burn subtitles into the video; export at original / 1080p / 720p, with playback speed control.

Local-first, and consistent across both platforms.

Screen recording, editing, and subtitles all happen on your machine—your original footage never leaves your computer.

Speech recognition runs locally with a built-in model—no internet, no cloud API calls.

Both platforms have the same features, with your account and Pro benefits shared across them.

When a new version ships, the app prompts you to update in one click.
