The composer is where a post comes together: your media from Drive, your caption, and every destination it's headed for — all in one editor. You write once, tune each platform where it matters, and see exactly how the result will look before anyone else does.
Pick your destinations
One post can go to any mix of destinations across your connected accounts:
- YouTube — Longform or Shorts
- Instagram — Post, Reel, or Story
- TikTok — Video or Photo
- X — a post, with threads of up to 50 follow-up posts
- LinkedIn — a post
Toggle destinations on and off at any time while drafting; the composer adjusts its options and previews to match.
One caption, per-platform overrides
Write your description once and every destination inherits it. When one platform needs something different — a shorter hook for X, hashtags for Instagram — add a per-platform override for just that destination. The shared caption stays the source of truth for everything you haven't overridden, so a late edit flows everywhere it should and nowhere it shouldn't.
Live previews
Every destination renders its own live preview as you type: Instagram looks like Instagram, YouTube looks like YouTube, X looks like X. This is where caption cuts, aspect-ratio surprises, and thumbnail problems show up — while they're still a ten-second fix. The full set of rules the previews check against is in the platform limits cheat sheet.
Destination-specific options
Each platform adds its own fields to the composer: YouTube asks for a title, thumbnail, visibility, and made-for-kids setting; Instagram lets you choose Post, Reel, or Story; TikTok requires a privacy selection and consent on every publish; X opens a thread builder for follow-up posts.
Post statuses: draft, scheduled, posted
A post moves through three statuses: draft → scheduled → posted. Drafts autosave leniently — you can save half-finished work that's over a caption limit or missing media. The hard limits are enforced at publish, when they actually matter. Ready to pick a date? See scheduling with the content calendar.
Content is frozen at publish time
At the moment of publishing, Soontra takes a snapshot of your post — captions, media, and settings — and delivers that. Editing the post or its media afterward never changes a delivered or in-flight post. If something needs to change after delivery, edit it on the platform itself.
