Publish your first post

This walks through the composer end-to-end. By the end you'll have published — or scheduled — a post to one or more channels.

1. Open Compose​

From the dashboard, choose Compose. This opens the publishing wizard.

2. Pick your destinations​

Select one or more connected accounts in the channel picker. You can mix platforms — e.g. one Instagram, one X, one LinkedIn — in a single post. This is cross-posting: one logical post, fanned out to multiple channels.

3. Write your caption​

Type your caption in the editor. The character counter adapts to the selected platforms; for example, X free-tier posts are capped at 280 characters, while LinkedIn allows 3,000. See Text & character limits.

You can also set a first comment that will be posted immediately after the main post goes live — useful for hashtags, links, or context you want to keep out of the caption.

Per-channel overrides​

Want a different caption on one channel? Use per-channel overrides to tailor text (or other fields) for a specific destination without splitting the post. The post stays a single unit, but each channel can render differently.

4. Attach media​

Drop in images or video from your media library or upload new files. The composer validates each asset against the destination platform's media limits — aspect ratio, resolution, duration, file size, and file count — and tells you immediately if something won't pass.

A few examples of what gets enforced:

  • Instagram carousel: 1–10 files, images ≤8 MB, video ≤45 Mbps / 15 min.
  • TikTok photo mode: JPG/WebP only (PNG is rejected), ≤20 MB each.
  • X video: ≤512 MB, ≤140 s on free tier.

5. Publish, schedule, or draft​

Choose what happens next:

ActionWhat it does
Publish nowSends immediately to all selected channels.
ScheduleQueues the post for a specific time (per-channel timezone aware).
Save draftStores it for later; nothing is published.

If you schedule, the post shows up on the calendar, where you can reschedule by dragging, duplicate it, or review the queue.

6. Watch it ship​

Once published, the post moves to Posts. Insights (likes, comments, reach, impressions) sync in over time as the platforms report them — see Analytics.

If something fails on a specific channel (for example, a media asset was rejected by the platform after submission), the post is marked failed for that channel with the platform's error message, and you can retry or edit.
