TikTok and short-form video (Reels, Shorts, TikTok) operate on a fundamentally different logic than every other content format. On YouTube, subscribers find you. On Instagram, followers see you. On TikTok, the For You Page (FYP) distributes your content to people who have never heard of you — and it decides how many people see it based almost entirely on how many people who saw the first 5 seconds kept watching.
This makes the script the distribution mechanism. A script that fails to retain in the first 3 seconds fails the algorithm. A script with a weak middle section causes drop-off, and the algorithm pushes the video to fewer people. A script that gets watched to 80%+ completion on a regular basis becomes a growth engine.
AI can accelerate the script-writing process significantly — but short-form video scripts are the format where AI needs the most editing, because the difference between a script that feels authentic and energetic and one that feels scripted and corporate is immediately visible on camera.
The hook is everything (0-3 seconds). On TikTok and Reels, users are mid-scroll at 1.5x speed. The viewer's brain is making a binary decision: stay or skip. The hook must create an immediate reason to stay — a surprising claim, a pattern interrupt, a question that creates curiosity, or the beginning of something that can't be resolved in 3 seconds.
Weak hooks: "Hi guys, today I'm going to share..." / "So I've been thinking a lot about..." / "Welcome to my channel!" Strong hooks: "You're losing money every time you do this." / "I tried 30 content strategies. Only one actually worked." / "The advice I wish someone gave me 3 years ago."
Pacing matters more than content density. Short-form video is consumed at a speed that written content isn't. Viewers expect a new piece of information, a scene change, or a plot development every 5-10 seconds. A 60-second video that lingers on one point for 20 seconds loses viewers in the middle.
The payoff must justify the hook. If your hook promises "the mistake that's killing your content," the video must deliver that insight clearly and specifically. Hooks that overpromise produce strong initial holds but low completion rates — and the algorithm learns quickly.
Pattern interrupts sustain watch time. Something that breaks the visual or verbal pattern every 10-15 seconds — a cut, a graphic, a change in energy, a new sentence that surprises — helps prevent the autopilot scroll that causes mid-video drop-off. In your script, mark where you intend these interrupts to happen.
15-30 second videos (TikTok ads, Reels clips, Shorts hooks): approximately 50-75 words. Hook + one key message + CTA. No room for setup.
30-60 second videos (most TikTok organic content, Reels, Shorts): approximately 100-160 words. Hook + quick setup + main insight/payoff + CTA.
60-90 second videos (extended TikTok, longer Reels): approximately 180-250 words. Hook + setup + 2-3 key points + payoff + CTA. Each point should take 15-20 seconds.
Speaking pace reference: average casual speaking pace is approximately 130-150 words per minute. At a slightly faster TikTok pace of 150-160 words per minute, a 60-second script is approximately 150-160 words.
Short-form scripts fail when they try to make multiple points. Define, in one sentence, what the single insight or takeaway of this video is:
This is your video's core. Everything in the script exists to deliver this one point effectively.
Use Typely's AI Chat:
"Write a TikTok/Reels script on [your topic]. The core message is: [your one-sentence insight]. The audience is [description]. Length: [target length, e.g., 45-60 seconds / approximately 130-150 words]. Hook: must create immediate curiosity or make a surprising claim in the first 2-3 seconds — do NOT start with 'Hey guys', 'Welcome', or any greeting. Format: spoken word, short sentences, punchy pacing. Include [number] distinct points or beats in the main section. End with a clear CTA: [subscribe/comment with X/follow for more/link in bio]. Mark any intended pattern interrupts or visual cues in [brackets]."
After generating, count the words and time yourself reading aloud at your normal speaking pace. The script should be the right length when you read it naturally — if you're rushing to finish, it's too long; if it runs short, add a specific example or expand one point.
Use Typely's Extend Text tool if you need to add substance to a section that's logically complete but too brief.
This is the most important editing step for short-form video. Read the script aloud with the energy you'd actually use on camera. Mark every line that:
Rewrite those lines in your actual voice. The goal is a script you can deliver with natural energy, not one that sounds polished on paper but wooden on camera.
Typely's AI Text Humanizer is useful here — run overly formal sections through it and select the most conversational output, then edit further for your specific voice.
The bold claim hook. State something surprising or counterintuitive that your audience hasn't considered.
"Write 5 hook sentences (under 15 words each) for a TikTok about [your topic]. Each should start with a bold or counterintuitive claim. No 'Hey guys' or 'Today I want to share.'"
The question hook. Ask a specific question that creates immediate curiosity.
"Write 5 hook questions for a TikTok about [topic] that a [target audience] would feel urgently curious about. Each should be specific, not generic ('How do you X?' not 'Do you want to know something interesting?')."
The story hook. Drop the viewer mid-scene into a specific moment.
"Write 5 story hook sentences (under 15 words) for a TikTok about [topic]. Each should drop the viewer into a specific moment or situation — no setup, straight into the action."
The mistake or warning hook. Position the viewer as about to make or having already made an error.
"Write 5 hook sentences for a TikTok about [topic] that use a 'mistake' or 'stop doing X' framing. Must be specific, not generic."
Test your selected hook by showing it to someone who would be in your target audience and asking whether they'd want to see the rest of the video. If they're not immediately curious, try a different hook type.
TikTok captions serve primarily as search and discovery text, not as engagement drivers. TikTok's search function indexes captions, so keyword-rich captions improve discoverability.
Use Typely's AI Chat:
"Write a TikTok caption for a video about [topic]. The caption should: be 100-150 characters, include the keywords [list 2-3 primary keywords naturally], and end with an engagement hook question. Then suggest 5-8 hashtags: mix 2 niche hashtags, 3 mid-size hashtags, and 2 broader hashtags relevant to [topic] and [your niche]."
For creators producing 5-7 TikToks per week, batching script production makes the volume manageable:
This workflow keeps scripting, filming, and editing as separate cognitive tasks, which is more efficient than trying to script, film, and edit each video individually.
