No Nimbus account required. Optional cloud inference. No telemetry. Models you choose are downloaded to your device and run locally. Processing stays on your phone unless you explicitly enable optional network features (such as web search or a BYOK cloud provider in Cirrus). Purchase Nimbus8 Pro once through Apple In-App Purchase. Restore anytime with your Apple ID. Family Sharing follows Apple's IAP rules. Privacy policy: https://trynimbus.org/privacy.html

About

Take a Stack

Features
Read full description

Save an immutable script and selection manifest, then compare the current project against it. See changed copy, reordered lines, different takes, gap changes and unavailable audio before you deliver again. HOW IT WORKS 1. Open a script and choose Delivery checkpoints. 2. Name and save a checkpoint of the current script, selected takes and gaps. 3. Edit a line or continue recording through the normal project workflow. 4. Return to the checkpoint, filter changed lines and share a detailed change report. Keep line-by-line recording, take selection, Alt Take Rescue, recording tools, stitching, mastering and audio exports. Checkpoints do not alter your selections. WHAT TO KNOW Checkpoints are manifests, not audio backups. They do not copy or restore recordings, measure listening quality or export a mix. Audio contents and export or processing settings are not compared. File presence does not verify playback. Keep separate exported-audio backups. iPhone and iPad.
