FAQ

Does it post without asking?

No. Every post is drafted into a queue. It schedules or publishes only the specific items you approve.

Do I need Buffer or Postiz?

Postiz or Buffer is the easiest hub, but it can also draft into a CSV queue you paste into each native scheduler.

Can it run two LinkedIn accounts?

Yes in principle, but respect platform limits — use separate browser profiles or connectors per account when one login cannot hold both.

Will it buy likes or auto-DM people?

No. No like-pods, follow/unfollow bots or mass DMs. Draft posts and optional comment replies only.

Will it act without asking me?

No. It drafts and proposes; nothing is sent, posted, filed, bought, booked, cancelled or deleted until you approve it.

Is my data shared anywhere?

No. Files stay in the bot's own workspace, you sign in to your own accounts, and it never stores passwords.
