How It Works
Describe your target audience — their role, context, and what they care about on TikTok. Choose what you want the video to accomplish: go viral, drive profile follows, link-in-bio clicks, a sale, or brand awareness. Write your hook — the exact words you'll say or show in the first 3 seconds — and paste your full script. Select your video format and hit analyze.
Our AI evaluates your script across five dimensions: hook power (will the first 3 seconds stop the scroll?), retention structure (does the middle of the video keep viewers watching to the end?), ICP relevance (does the content speak to your specific audience's context?), shareability (will viewers send this to someone else?), and CTA effectiveness (does the ending move people toward your goal?). You get a letter grade, a plain-English summary, and the single most impactful change you can make — free, in seconds.

What You'll Get
Free analysis includes your overall grade (A through D), a one-sentence summary of your script's main strength and weakness, and the single highest-leverage change you can make before filming.
Full report (free account required) includes:
Hook Power (0-3 sec) — will the first line stop the scroll or get swiped past in under a second?
Retention Structure — does the script give viewers a reason to keep watching all the way through?
ICP Relevance — does the content speak directly to the specific context and pain points of your described audience?
Shareability — will viewers feel compelled to send this to someone else, or is it content they consume and forget?
CTA Effectiveness — does the ending feel natural and move people toward your stated goal?

Why the First 3 Seconds Decide Everything on TikTok
TikTok's algorithm measures completion rate — what percentage of viewers watched your video all the way through. A video with a weak hook gets swiped past in the first second, which tanks your completion rate, which tells the algorithm not to distribute it further. Everything else in your script becomes irrelevant if the hook doesn't hold attention long enough for the rest to be seen.
The hooks that work share a few patterns:
They create an open loop — the viewer has to know how the sentence ends, or what the payoff is
They speak directly to a specific experience the target audience has already had ("If you've ever tried X and it didn't work…")
They start mid-thought — no "Hey guys," no "So today I want to talk about," no preamble of any kind
They're specific enough that the wrong audience self-selects out, and the right audience leans in
This is why we ask for your hook separately. It's the highest-leverage sentence in your entire script, and it deserves its own focused analysis.
How Numi Scores Your TikTok Script
Most TikTok content tools focus on trends, sounds, and posting schedules — not the quality of your script against your specific audience. Numi evaluates your script relative to the audience you describe, the goal you've selected, and the format you've chosen. The five scoring dimensions are chosen to reflect what actually drives TikTok performance for goal-oriented content:
Hook Power (0-3 sec) — the first 3 seconds of a TikTok determine whether most viewers stick around. This score measures whether your opening creates enough pull to earn the next 30 seconds
Retention Structure — measures whether the pacing, payoff delivery, and narrative arc of your script keep viewers watching through to the end
ICP Relevance — evaluates whether your content speaks to your audience's actual situation, not just a generic version of their demographic
Shareability — scores whether the video has a "I need to send this to someone" quality — a surprise, insight, or emotional trigger that makes sharing feel natural
CTA Effectiveness — checks whether the call to action is specific, believable, and aligned with the goal you selected
Frequently Asked Questions
A TikTok script analyzer evaluates your video script against your stated target audience and video goal. It scores five dimensions — hook power (first 0-3 seconds), retention structure, ICP relevance, shareability, and CTA effectiveness — and identifies the single most impactful change you can make before filming. Unlike generic readability tools, this analyzer adapts its scoring to the specific audience you describe and the video format you've chosen, so you're optimizing for your actual viewers, not generic TikTok benchmarks.
TikTok hooks that stop the scroll share three traits: they create an immediate open loop that makes the viewer want to see how it ends, they speak directly to a specific emotion or pain point the target audience already feels, and they avoid any preamble — the first word of your script should be the most compelling word, not "Hey guys" or "So today I want to talk about." The best hooks are statements or questions that would make your target viewer think "that's exactly me" or "I need to know the answer to this."
TikTok's algorithm distributes content based on completion rate, shares, and replays — not follower count. Videos that go viral earn those signals by: hooking viewers in the first 1-2 seconds so they don't swipe away, structuring the middle to deliver on the promise of the hook without losing momentum, and ending with something shareable — a punchline, a surprising reveal, or a CTA that feels natural rather than forced. A script that gets watched to completion by the right audience will be shown to more of that audience, compounding reach.

Yes, significantly. A Talking Head script needs a strong verbal hook and tight pacing because viewer attention depends entirely on what you're saying and how you're saying it. A POV script relies on situational relatability and implied context. A Tutorial needs clear structure and payoff at each step. A Storytelling video can sustain longer attention but requires narrative tension. A Before/After script needs a compelling transformation promise up front. This analyzer evaluates your script against the specific format you've chosen and flags when the scripting approach doesn't match the format's expectations.
