The problem
Most "online editors"
aren't real editors.
They're text-based editors that make you edit by rewriting a transcript, or template generators with a gallery of pre-made looks and no way to deviate.
A real editor has a timeline, a waveform, clip boundaries, audio layers, and overlay tracks you can move. Sapari has all of that — built in the browser, identical on every device.
What the editor is
Five pieces, one surface.
Multi-clip preview
Stitches your clips into one playhead. Seamless transitions at clip boundaries.
Waveform timeline
Audio peaks, silence gaps, and every AI-detected edit color-coded by type.
Edit cards strip
Every edit also appears as a card. Filter by type, click to jump, accept or dismiss.
Asset overlay track
B-roll, logos, lower-thirds, watermarks. Drag to reposition, resize, change opacity.
A/B comparison
Toggle between original and edited mid-playback. Compare without re-exporting.
Mobile is the full editor
The phone version
isn't a stripped-down
companion.
Same editor, running in a browser tab. Touch targets sized to WCAG 2.5.5 (44px minimum), pinch-zoom on the timeline, swipe review on edit cards, haptic feedback on edge snaps where the hardware supports it.

Before you ask
Common questions.
Is this really a timeline, or a glorified trim tool? +
It's a real timeline — multiple tracks, drag-adjustable boundaries, overlay positioning, A/B comparison, keyboard shortcuts. Not a trim slider.
How long a video can the editor handle? +
Tested up to 2-hour podcasts. The waveform renders progressively so long durations don't freeze the browser.
Does the mobile editor really work? +
Yes. UI sized for touch, timeline supports pinch-zoom, edit cards support swipe review. You can do an entire edit from your phone.
What if the AI gets something wrong? +
That's what the timeline is for. Drag the boundary, dismiss the card, add a manual edit — you always override.
Offline support? +
No. The AI analysis and the video streaming both require a connection.
