Record without leaving the app
Choose Record screen and videoFn steps out of the way. Pick a screen or a window, talk over it if you like, and the recording lands straight in a project.
SaaS product demo video maker for Mac
Your product, explained in thirty seconds.
Hand over a few screen recordings and the three things people should remember. Get back a short narrated demo in which the product actually does something.
videoFn is a Mac video editor that Claude or ChatGPT can drive. Describe the video, watch it come together in the preview and give notes. If you'd rather fix something yourself, the editor is right there.
make a 20-second demo for Beacon: the messy list, the sorted list, adding a task, focus mode, then try it free
generating the narration, one take per scene
drawing the Beacon window in five scenes
zooming in on the input as the task is typed
captions timed to every word
Beacon is fictional, so videoFn drew its interface for this example. The narration, captions, camera moves and music mix were made in videoFn too.
Nobody wants to make the demo. Everybody wants to have one.
The one you'd make
Eleven minutes long. Opens on the settings page. Every feature gets equal time, including the export dialog. Narrated in one take at 1am, with a dog barking somewhere.
The one you'll ship
Thirty seconds. Opens on the problem. One feature per scene, the right part of the screen in focus, captions for people on mute and a voice that has slept. Claude or ChatGPT does the editing; you keep the facts straight.
From screen recording to something people finish.
Narrate it, or don't
Generate a voiceover on your Mac and try a few voices. Or use your own recording, with the background noise reduced, the level evened out and the ums taken out.
Point at the thing
The agent times each scene to the line that mentions it and zooms in on the part of the screen that matters. Nobody has to hunt for a button in a full-screen capture.
Give notes, not keyframes
Say “the middle drags” or “lose the settings bit” and the agent recuts it. The project stays editable, so next release you swap the clip that changed.
One demo, every place it needs to go.

Ask for each one from the same project. For the App Store, Apple has its own rules about length, sizes and content. See App Store preview videos.
Questions, answered.
- Can videoFn record my screen?
- Yes. Choose Record screen, pick a screen or a window and add a microphone if you want to talk over it. The recording goes straight into a project, at up to 4K.
- Do I have to narrate it myself?
- No. videoFn generates a voiceover on your Mac from your script, and you can try a few voices. If you'd rather use your own voice, it cleans up the noise, the levels and the ums.
- Will it make my product look better than it is?
- It will make it look clear, which is usually enough. The footage is your real product, and you check every claim in the preview before you export.
- What about a mobile app?
- Record the iOS Simulator window, or bring recordings from your phone. For the App Store itself, see App Store preview videos.
- Can I update the demo when the product changes?
- Yes. The project stays editable, so you swap in the new recording and ask the agent to fit it in, rather than starting again.
