Voicenotes do not allow you to upload audio files, you can only record new notes. Here's why:
We have underlying costs to offer the AI features, and offering file uploads would make it significantly harder to offer the same great price.
Voicenotes is a voice journalling app and we want to focus on building features that are true to its core idea and audio upload isn't one of them. Voice Memos on Apple, for example, do not allow you to upload either.
If you have unique use-cases which requires upload, we know this is not ideal to hear. But we have good news for you: we're figuring out ways to introduce an import feature that will allow you to upload/sync all your existing notes and audio (from Voice Memos, for example) to your Voicenotes account. This would allow your AI to have full context of your notes. It's a work in progress and we'll let our users know as soon as we make progress on this one.
