Why creators give up on short-form
Short-form burns out the best creators.
Scripting, hooks, captions, vertical re-edits, hashtags — the editing tax kills the channel before it grows.
Blank-script paralysis
Staring at the editor at 11pm trying to remember the hook framework that worked last week.
Retake hell
Recording 4 takes because the captions and shot order weren't planned.
Flat-line opens
Posts die in the first 1.5 seconds because the hook never earned the watch time.
Platform whiplash
TikTok, Reels and Shorts each need a different tone — most tools give you one script.

FAQ
Questions creators ask first.
Is the script generator really free?+
Yes — 3 scripts per month on the free tier, no credit card. Pro unlocks unlimited generation plus voiceover, AI cover thumbnails, Series mode, and brand voice training.
Which languages does it support?+
100+ languages. Set the source language in your input and PostSpark generates the script, captions and hashtags in that language.
Can I record from the script directly?+
Yes. Export as .txt for any teleprompter app, .srt for auto-captions in CapCut or Premiere, or generate the AI voiceover and drop it straight into your edit.
Do I own the scripts?+
100% yours. PostSpark gives you the output — no watermarks, no attribution, no usage restrictions.
How is this different from ChatGPT?+
ChatGPT gives you text. PostSpark gives you a hook-scored shot list, voiceover audio, b-roll matches, on-screen captions, SRT export, trending audio, and a cover thumbnail — built specifically for vertical video.
What platforms is the output tuned for?+
TikTok, YouTube Shorts and Instagram Reels — each gets a different hook tone, caption style and hashtag pattern. We're adding LinkedIn video and Pinterest Idea Pins next.
Can I publish directly from PostSpark?+
YouTube publishing is live. TikTok, Instagram and LinkedIn are rolling out as those platforms approve our developer apps — your scripts and videos are ready the moment they ship.
What's the multi-clip editor?+
Upload up to 5 clips, drag to reorder, trim, crop to 9:16, burn captions, and export a finished WebM — all in your browser. No CapCut, no Premiere, no install.
