Questions

Can the assistant publish without asking?

Everything it writes is saved as a draft. It publishes or schedules only when it calls a separate tool for that, and the plugin tells it to show you the post and ask first.

What can it do?

See your channels; list, read, write, edit and delete posts; attach pictures and video from a link; schedule, unschedule and publish. On plans with analytics it also reads followers per channel and what Postia delivered.

It cannot connect new networks, and Postia has no reach, views or likes per post for it to read.

How do I disconnect it?

In Postia open Settings, then Account, then AI assistants, and press Disconnect. Its access stops at once.

Is there a key to paste?

No. The assistant signs in through your browser: Postia asks whether to let it in, and it never sees your password.

Every network is on every plan, the free one included, and the first 14 days come with all of Studio.
