Open Compose and work top to bottom:
1. Pick the account
Your connected accounts appear as chips at the top. Click to select one or several — selecting accounts on different platforms cross-posts the same content to each.
2. Add media
Upload photos or one video. Instagram takes up to 10 photos in a carousel. TikTok takes up to 35. Threads and Facebook post the first image only. JPEG is the most reliable photo format across platforms, and video should be vertical 9:16 for Reels, TikTok, and Shorts. Threads also works text-only.
3. Title and caption
A title is required for YouTube and TikTok. The caption is optional everywhere — use Quick Captions to reuse ones you save.
4. Platform settings
If you selected TikTok, choose a privacy level (TikTok requires this on every post — the section is open by default). YouTube's category and privacy live in a collapsible section with sensible defaults.
5. When to post
Pick Now, In 1 hour, Tomorrow 9AM, or a custom date and time. Then hit Schedule — your post appears on the Schedule calendar, and sprkly publishes it automatically at the right minute. If a publish fails, we retry automatically and email you if it can't recover.
