// our mission

Your projects should outlast the software you build them with.

Creative software has become increasingly dependent on accounts, servers, subscriptions, and tiered cloud storage. Annotone takes a more boring approach on purpose: your files remains on your device, your notes are stored as plaintext files anyone can read, and the software you buy is yours for life.

Questions people ask

Does Annotone upload my audio anywhere?
No. Annotone only opens audio files that are already on your computer. Your files are never sent to a server by design.
Does Annotone work offline?
Annotone runs entirely locally, so you can review and annotate audio regardless of whether your device is connected to the Internet.
What happens if the person I'm working with doesn't have Annotone?
Your annotations are saved as plain text, so they can still open and edit the notes using an ordinary text editor. Or send them a password-protected review link they can open in their browser without installing Annotone. You can share the audio using whatever file-sharing method you already use.
Do my collaborators need to buy Annotone?
Not to read or edit the notes you send them. Annotone saves annotations in a human-readable format that can be opened without the app. They can also open a password-protected review link in their browser without installing Annotone. If they want to use Annotone itself to review and annotate audio, they'll need a license.
Can I use Annotone on more than one computer?
Yes. A single Annotone license can be activated on up to three of your computers.
What does a lifetime license actually mean?
A perpetual license — you own Annotone and it works forever. Patches and fixes are free. Because Annotone runs locally and dependency-free, it is designed to be something you can truly own and use in perpetuity. If we ever ship a major new version (think a considerable new feature set, not just polish), existing customers get it at a significant upgrade discount.
What audio formats are supported?
WAV, MP3, and FLAC.
Does it work inside my DAW?
Not yet. Annotone is a standalone app today. A DAW plugin is planned for a later release.
