SocialAgent draft review with platform captions, a channel preview, sources and publishing destinations

A short version, not a cut one

The X body is generated and edited separately against the 280-character limit, so the payoff of a longer post is never chopped off.

Media up to four images

Images are uploaded with size bounds checked before the post is created, and each destination is tracked separately.

PKCE and refresh tokens

X is authorized with PKCE and a refresh token, renewed before publishing so scheduled posts keep working weeks later.

Approval-first

Every draft waits for you. An interrupted publish with an unknown result is held for reconciliation, never blindly retried.

Review

Nothing publishes unread

Every draft opens with its platform versions, the publishing time in your timezone, the accounts it will post to and the research excerpts behind any factual claim. Approving is bound to that exact revision.

FAQ

Common questions

Can I schedule X posts?

Yes. Draft with your own AI key, pick a time on your calendar, approve, and the post publishes on schedule. Tokens are refreshed before publishing so a schedule set weeks ahead still works.

Do I need an X developer account?

No. You authorize your own X account through the standard OAuth flow as a user. SocialAgent handles the publishing API on your behalf.

How does link length work on X?

X rewrites every link to a fixed 23 characters regardless of the original length, so shortening a URL saves you nothing. The SocialAgent character count and our free counter both account for this.

Can I auto-publish to X?

Automatic publishing is an explicit opt-in per schedule. By default every post waits for your approval.
