Most short-form scripts fail because they're written like blog posts - front-loaded with context, with the payoff buried 20 seconds in. Short-form is the opposite: hook in 0–3 seconds, setup by second 8, deliver the value beat-by-beat through second 25, then a CTA that doesn't feel like a CTA. The Inflowave Script Generator builds your script in those exact time blocks for 15s, 30s, 60s, or 90s videos, returns matching B-roll cues and on-screen text, and ships in the cadence each platform's audience actually rewards.
How it works
- 1Enter your topic - be specific. "Why most fitness advice is wrong" beats "fitness tips" every time.
- 2Pick a duration: 15s for high-velocity loops, 30s for the sweet spot, 60–90s for educational deep-dives.
- 3Select platform - TikTok, Reels, or Shorts. We adjust pacing, sentence length, and CTA style per platform.
- 4Get a fully-timed script with hook, setup, value block, CTA, plus B-roll suggestions and on-screen text overlays.
Who uses this tool
- Faceless creators who batch 5–10 scripts in one Sunday session and need each one to be production-ready.
- Coaches and consultants turning long-form podcast clips into native short-form scripts.
- UGC creators writing scripts for brand briefs that need to feel native, not like a 30-second ad.
- Editors who get raw footage with no script and have to reverse-engineer one for the voiceover.
- Founders documenting build-in-public who keep rambling for 90 seconds when 30 would convert better.
- Agencies producing 50+ scripts a month per client where blank-page time is the actual cost center.
Why this beats the generic AI tools
- ✓Time-block structure (0–3s, 3–8s, 8–25s, 25–30s) - most generators output one wall of text with no pacing.
- ✓Includes B-roll cues and on-screen text, not just dialogue. That's 60% of short-form production.
- ✓Platform-tuned: TikTok scripts run faster and rawer; Reels scripts are slightly more polished; Shorts scripts have a YouTube-search-friendly opener.
- ✓Built for retention curves, not just "engaging copy" - every block is sized to the second-by-second drop-off pattern of each platform.
- ✓Free, no signup wall, drop your email when you want the script delivered.

Generate yours free ↓The 4-block structure that actually retains viewers
Hook (0–3s): pattern interrupt + a specific promise. Setup (3–8s): one sentence of context so the viewer knows what they're about to watch - skip this and viewers feel lost and bounce. Value (8–25s): deliver 2–4 distinct beats, each ~3–5 seconds, so the viewer feels progress. Drop the payoff in the final value beat, not at the end. CTA (25–30s): low-friction ("comment X for the full guide" or "follow for part 2") - never "link in bio" alone, that's where retention dies. The generator builds your script directly into these blocks.
Why short-form scripts are different from YouTube long-form
Long-form rewards depth, exposition, and narrative arcs. Short-form rewards density and momentum. A 10-minute YouTube video can spend 90 seconds on context; a 30-second Reel cannot afford 3 seconds of throat-clearing. Sentence length matters: keep them under 12 words on average. Avoid filler ("so basically," "you know," "the thing is"). Every sentence should either pay off the hook, deliver a beat, or set up the next beat. The generator enforces this structure so you don't have to fight it on the page.
TikTok vs Reels vs Shorts - what changes in the script
TikTok: faster cadence, punchier sentence fragments, audience tolerates bigger swings and rougher edges. Reels: slightly more polished tone, audience skews older and more aspirational, hooks lean visual rather than verbal. Shorts: opener should hint at search intent ("Here's how to…", "3 reasons why…") because Shorts pulls heavy traffic from YouTube search and discovery, not just the feed. The generator adapts vocabulary, sentence length, and CTA style to whichever platform you select.
FAQ
How long should a TikTok or Reels script be?▾
For a 30-second video, target 65–80 spoken words - anything more and you'll rush delivery and lose retention. 15-second scripts run 35–45 words. 60-second scripts run 130–150 words. The generator outputs the right word count automatically based on the duration you pick.
Should I write my own script or use a generator?▾
Use the generator for the structure and starting draft - hook, beat sequence, CTA. Then rewrite in your own voice. AI is best at pacing and frameworks; you're best at the specific word choices, references, and personality that make a script feel like you and not like generic content.
What's the ideal hook-to-CTA ratio in a 30-second video?▾
Roughly 10% hook (3s), 17% setup (5s), 56% value (17s), 17% CTA + outro (5s). The generator follows this ratio. If you cut the value section to add more CTA, retention drops and the algorithm pushes the post less - so resist the urge to over-CTA.
Can I use these scripts for paid ads?▾
Yes. The same retention principles drive Spark Ads on TikTok and Meta Reel ads. Many of our agency users ship scripts straight from the generator into UGC creator briefs. The 4-block structure works just as well for paid as organic - arguably better, since paid is even more retention-sensitive.
Does this work for talking-head videos and faceless videos?▾
Both. The script structure is independent of format. For faceless videos, lean harder on the B-roll suggestions and on-screen text fields the generator returns - that's where retention is actually held in faceless content. For talking-head, the on-screen text becomes secondary and your delivery carries the beats.
