Needs a paid plan

Connecting X is gated behind a plan feature, unlike every other platform on this list, which every plan can connect. Trying to connect on a plan without it tells you to upgrade.

Connect

Settings, then Connections, then X. OAuth redirect (PKCE), approve, return.

What it can post

A single sharp idea fits the 280 character limit; a longer thought needs a thread. A first comment can follow the post, and a thread follow-up can be scheduled alongside it.

Metrics

X post metrics and follower counts sync automatically. See Metrics.

Engage

X has no Engage support today: replies and mentions on X do not reach your Inbox.

Cost

Posting to X costs nothing extra per post. AI credits are only spent on AI generation, never on publishing.
