YouTube Shorts is one of the fastest-growing short-form video formats, with over 2 billion monthly logged-in users watching Shorts. If you're promoting an app or building an audience, Shorts gives you access to a massive discovery engine — but managing uploads, titles, and scheduling directly on YouTube is slow and repetitive.
MakePost lets you schedule YouTube Shorts, set the perfect publish time, and cross-post the same video to TikTok, Instagram Reels, and other platforms in a single step.
How It Works
Connect your YouTube channel
Link your YouTube account in one click. No API keys or developer credentials needed — just authorize MakePost through your Google account.
Upload your video and add a title
Upload vertical videos (1080x1920). MakePost automatically adds #Shorts to your title so YouTube categorizes it correctly.
Schedule or publish immediately
Pick the best time for your audience and schedule it. Or publish right away. Either way, you can cross-post the same video to TikTok, Instagram, Facebook, and more in the same step.
What You Get with MakePost + YouTube
Automatic #Shorts tagging. MakePost adds the #Shorts hashtag to your video title automatically, so YouTube's algorithm picks it up as a Short rather than a regular video.
Multiple ways to publish. Use the dashboard for hands-on control, the REST API for custom integrations, or connect AI assistants like Claude and ChatGPT via MCP to fully automate your workflow.
Cross-platform publishing. The same video you upload for YouTube Shorts can be published to TikTok, Instagram Reels, Facebook Reels, X, LinkedIn, Threads, Pinterest, and Bluesky — all from the same upload.
AI-generated captions. Generate engaging titles and descriptions with AI, optimized for YouTube's search and discovery.
Bulk scheduling. Schedule multiple Shorts at once. Plan your content calendar days or weeks ahead and let MakePost handle the publishing.
