## What is JEM Studio?

JEM Studio is a fast, private video editor for reels and short videos, built to be reliable, honest, and completely yours.

Import your clips and photos, edit on a simple timeline, and export without a watermark straight to your camera roll. No account. No cloud storage of your media or projects. No watermark held hostage. JEM Studio does not upload your media anywhere.

EDIT
• Trim, split, reorder, and delete clips
• Text overlays with clean, tasteful presets
• Adjust clip speed
• Photo support: turn stills into timeline clips

AUDIO
• A bundled 30-track music library with real album art, searchable by title, artist, and mood, organized by category (cinematic, comedy, casual, retro, suspense, and more)
• A classical shelf worthy of the name: Bach's Goldberg Variations performed by Kimiko Ishizaka (Open Goldberg Variations), Debussy's Clair de lune, Satie's Gymnopédie No. 1, Beethoven's Moonlight Sonata, Vivaldi's Spring, and Massenet's Méditation in Mischa Elman's 1919 recording
• Preview any track, save favorites, and add it to your reel in one tap
• Record voiceover right in the app
• Import your own audio
• Per-clip volume and mute

EXPORT
• without a watermark export to your camera roll
• Multiple quality options
• Share anywhere

PRIVATE BY DESIGN
• No account required, ever
• No cloud storage for your media or projects
• JEM Studio does not upload your media
• Editing and export run on device, so the editor works offline
• No ads, and no tracking
• Optional anonymous usage sharing is off by default, and sends nothing unless you turn it on

Honest and complete: no paywall traps, no watermark ransom. Just a clean editor that respects you and your work.

## Version history (last 2 releases)

### 1.1 — 2026-08-09

Trimming is rebuilt. Tap any video clip to open it, then play the part you kept, slide the playhead anywhere and watch the time, and drag the yellow handles. Trim a clip short and the window opens up so you can still place the cut exactly.

### 1.0 — 2026-07-30

No release notes.
