Every detail designed for teaching
Not a generic screen recorder—a tool that truly understands how teachers teach.
Real-time annotation
Draw, arrow, highlight, and box directly on your screen while you teach. Whatever you point at gets marked, and the annotations are baked right into the recording.
Zoom to focus
Magnify the part you are explaining with one tap, and let it follow your cursor. Code, formulas, and tiny details stay crystal clear.
Camera picture-in-picture
Circle or rounded face window, your choice, with mirror, zoom, and border options. Show your face and make your lessons feel more personal.
On-device subtitles
Built-in whisper.cpp transcribes offline. Nothing is ever uploaded. Then "edit the text to cut the video"—delete a wrong line and the matching clip is trimmed automatically.
One-click smart cut
Automatically detect and remove silences, filler words (um, uh, you know), and repeated retakes. Clean up a whole lesson in seconds.
Local processing, no uploads
Recording, editing, and subtitles all happen on your own computer. Your original footage never leaves your machine. Zero privacy worries.
Record, edit, export—three steps to a finished video
From opening the app to sending the video to your students, the whole process is simpler than you think.
Record
Capture full-screen or a region, with annotation, zoom, camera, whiteboard, and spotlight—explain it clearly in one take.
Edit
Open the editor, get auto-generated subtitles, remove silences / filler words / noise in one click, and add intros, music, and stickers.
Export
Export to mp4 at the resolution you want, with subtitles burned in. Open the output folder in one click and send it straight to your students.
