Record your own voice
Your voice, your face, your screen — recorded where you work
Open the Record tab, pick microphone, camera, screen, or screen-with-camera-bubble, and capture directly in the browser — no OBS, no uploads from another app. Attach a clip to a slide and it becomes that slide's narration or picture-in-picture overlay in the final video. Recording is free, always.
Manual narration is a first-class citizen
On both the Voiceover and Slides tabs, every slide offers “🎤 Record my voice” and “⬆ Upload audio” beside the AI button. Whatever you record — or upload as MP3, M4A, WebM, or WAV — is converted to the same 44.1 kHz studio format the AI produces, so playback, duration tracking, and video rendering work identically. A “manual voice” badge marks the slide.
Your recordings are protected: bulk AI generation skips manually-voiced slides, and replacing one requires a confirmation that says exactly what it will overwrite. A lost take is unrecoverable, so the studio asks first — always.
Why creators mix manual and AI
Recording your own narration is the biggest lever on production cost — writing and voicing a course yourself means you pay only the small processing utilities, which is how a three-hour course can cost under ten dollars to produce. Many creators narrate the welcome and story-driven lectures personally and let the AI voice carry the reference chapters. The studio doesn't care which you choose per slide; the pricing page shows exactly what each path costs.

Some lectures need your voice. Now that costs nothing.
