Twitter post scheduler work?

and effects

Go live
on every platform
Your video goes live on X at the scheduled time. See your published posts from the Submagic dashboard.
Why publish video to X from your editor
Most X (Twitter) scheduling tools handle text tweets and image uploads. Video is an afterthought: you edit elsewhere, export, upload the file, and type a caption from scratch. Submagic keeps everything in one workspace so your video goes from transcript to scheduled X post without leaving the editor.
The manual X video workflow
X schedulers handle text tweets, not video editing.
Edit, export, upload to scheduler
Write tweet copy from scratch
Resize and re-upload for tweaks

Frequently asked questions
Does Twitter have a built-in scheduler?
Yes. X (formerly Twitter) supports basic post scheduling through its web interface and X Pro (formerly TweetDeck, now requires X Premium at $8/month). Submagic adds AI video editing on top: captions, B-roll, effects, and sound applied to your video before scheduling. Edit and schedule from one workspace instead of two.
Can tweets be scheduled for free?
X's built-in scheduler on the web is free for basic tweets. X Pro (TweetDeck) requires a Premium subscription. Third-party tools like Buffer offer free tiers with limits, while Hootsuite starts at $99/month after a 30-day trial. Submagic's free tier includes Publish Now for one video. Scheduling for a future date and time requires a Pro or Business plan.
Can AI be used to schedule tweets?
Yes. AI tools generate tweet copy and suggest hashtags. Submagic's AI turns your video transcript into tweet-length captions and relevant hashtags tuned for X's format, then schedules the post automatically at the time you set.
What has replaced TweetDeck?
TweetDeck was absorbed into X Pro, which requires an X Premium subscription ($8/month or $84/year). The free standalone TweetDeck no longer exists. Third-party scheduling tools (Buffer, Hootsuite, Typefully, Hypefury) fill the gap for users who want free or lower-cost scheduling.
Do scheduled tweets get less views?
X does not penalize scheduled posts. The algorithm ranks tweets by relevance, recency, and engagement signals, regardless of whether you posted manually or through a scheduling tool. Batch-scheduling video tweets during high-traffic windows (weekday mornings and early evenings) often outperforms posting sporadically when you happen to be online.
Can tweets be scheduled without X Premium?
Yes, using third-party tools. Buffer, Hootsuite, Typefully, and Hypefury all offer tweet scheduling without requiring X Premium. X's built-in web scheduler also works without Premium for basic tweets. X Pro (TweetDeck) is the only scheduling method that requires a Premium subscription.
Why can't tweets be scheduled on mobile?
X's mobile app only supports drafts, not scheduled posting. To schedule from a phone, use a third-party tool (Buffer, Hootsuite, Typefully) or access X Pro through a mobile browser. Submagic's X scheduling works from any device through the web editor.
Can I schedule video posts to X with Submagic?
Yes. Edit your video with AI captions, B-roll, and effects, then toggle X on in the publish screen. AI generates a tweet-length caption and hashtags from your transcript. Set a date and time, and Submagic posts automatically.
What types of X posts can Submagic schedule?
Video posts with AI-generated captions and hashtags. Edit your video with AI captions, B-roll, and effects, then schedule it directly to X from the same workspace.
