Uploads are forced private

Every video Postlyra uploads to YouTube is set to private visibility, regardless of what you choose.

Google requires an API audit before an app may create public uploads, and Postlyra has not passed it yet. Until then, publish through Postlyra, then flip the video to public in YouTube Studio yourself.

Connect

Settings, then Connections, then YouTube. Google OAuth, approve, return.

Google's consent screen will warn about an unverified app until the audit clears. That is the same audit as above.

Publishing

Video only. There is no way to post a text update or a community post.

The 4 GB cap here is Postlyra's practical limit rather than YouTube's, which is higher. Uploads go directly from your browser to storage in parts, never through the app, then get probed and checked against the spec above before they can be scheduled. See Video uploads.

Metrics

YouTube reports subscriber counts and per-video metrics, both synced automatically.

Engage

Comments on your videos, and replies to them, arrive in your Inbox, read on a schedule. You can reply from there.

A reply you post from YouTube's own app is picked up too: it shows up in the thread, and the Reply score counts the comment as answered.

Saving YouTube videos

Paste a YouTube link into Save by link in Inspiration, or save one from the phone's share sheet or the Chrome extension. A pasted link comes back complete through YouTube's own API: title, description, counts and the caption transcript, for free. From there you can analyse it, turn it into hooks, ideas or a script, and pull a hook straight out of a video's transcript from Hooks.
