Why JEM Studio

Three facets of one editor

Reliable

Autosave and crash recovery mean an interrupted edit is not a lost edit. Losing your work is the failure we care most about preventing.

Honest

No ads, no trackers, and no upsell maze. The editor is the product, not your attention.

Private

No account, no cloud, and no data collection. Your footage never leaves your device unless you export or share it. See the privacy policy.

Capabilities

What it does

  • Import

    Bring in clips and photos through Apple's system picker. JEM Studio only sees the items you choose.

  • Edit on a timeline

    Trim, split, and reorder clips with a timeline built for precise, direct touch.

  • Add text

    Place readable text overlays where you want them.

  • Add audio

    Use your own recordings, add a voiceover, or pick from a small bundled library of public-domain and Creative Commons music.

  • Export clean

    Save finished videos watermark-free, straight to your camera roll.

  • Work offline

    No account and no connection required. Editing and export run entirely on your device.

JEM Studio is a native iPhone app, in active development. It has no backend, no advertising, and no analytics that leave your device.
