FAQ

Can this workflow publish automatically?

Not recommended. AI is useful for drafts, variants, and checklists, but facts, asset rights, and platform rules need human confirmation.

What if my tool stack is different?

Keep the workflow roles: ideation, generation, editing, review, and learning. Substitute specific tools with existing team accounts.
