A video editing tool can cut you a clean clip; it can't tell you whether the hook in the first two seconds is actually going to stop someone from scrolling. That's a different, newer category of tool: AI models trained on what makes short-form video perform, used either before filming (to score a script or hook idea) or after publishing (to diagnose why a video underperformed). The five tools below all do some version of that, but they split cleanly by platform coverage, pricing model, and whether they work before or after the camera rolls.
The tools compared at a glance
| Tool | Platforms | When it helps | Starting price |
|---|---|---|---|
| CheckViral | TikTok + slideshows | After publishing (diagnostic) | $9/mo (30 analyses) |
| HookMafia | Short-form, platform-agnostic | Before filming (script + hook scoring) | Free (10 credits), then $19/mo |
| TikAlyzer | TikTok, Instagram Reels, YouTube Shorts | After publishing (diagnostic) | $9.99/mo unlimited |
| ViralPulse | TikTok, YouTube Shorts, podcasts/audio | Before publishing (pre-score) | Free (3/day), then $7.99/mo |
| Wallo | TikTok (short) + YouTube (long) | After publishing (analysis + summary) | Not published |
CheckViral — structured 7-dimension breakdown
CheckViral analyzes any TikTok video or slideshow and breaks down why it did or didn't go viral across seven dimensions — hook, CTA, engagement, audience fit, and more — in about a minute.
Who it's for: TikTok creators, marketing agencies, and growing creator teams who want a structured post-mortem rather than a single vague score.
Price: Basic $9/month (30 analyses), Pro $25/month (100 analyses), Max $70/month (250 analyses); a 60%-off promo code is available.
Honest limits: it's limited to TikTok and slideshows — no native YouTube Shorts or Instagram Reels support — the Basic tier's per-analysis cost is high, and there's no free trial mentioned.
Verdict: the most structured diagnostic on this list if you're TikTok-only and want dimension-by-dimension feedback rather than a single number.
HookMafia — scores the hook before you film
Every other tool here analyzes a video after it exists. HookMafia works earlier: it researches what's trending in your niche, scores different hook angles before you film, and outputs a ready-to-shoot script with camera and scene directions.
Who it's for: independent creators, UGC producers, and agencies managing multiple clients who want to fix weak hooks before wasting a shoot day on them.
Price: free (10 credits), Creator $19/month (200 credits), Pro $39/month (500 credits), Agency $99/month (1,200 credits + unlimited clients); 18-21% off annually.
Honest limits: the credit system caps how much you can do on the free tier, and it's purely a pre-production tool — it doesn't analyze videos you've already published, so it doesn't replace a post-publish diagnostic tool.
Verdict: the only tool here that saves you from filming a bad hook in the first place, which makes it a natural pair with a post-publish tool rather than a replacement for one.
TikAlyzer — the multi-platform generalist
TikAlyzer covers TikTok, Instagram Reels, and YouTube Shorts in one tool, pinpointing exactly what's underperforming in a video — hook, retention, pacing — with unlimited analysis starting at its cheapest tier.
Who it's for: creators and content teams publishing across more than one short-form platform who don't want a separate tool per platform.
Price: Pro $9.99/month (unlimited analysis), Growth $19.99/month (adds video history), Creator $49.99/month (team collaboration + white-label), Enterprise quote-based; 7-day money-back guarantee.
Honest limits: video history is locked behind the Growth tier or higher, team collaboration requires the $49.99/month Creator tier, and Enterprise pricing isn't public.
Verdict: the best default pick if you post to more than one short-form platform, since $9.99/month for unlimited analysis undercuts most of the single-platform competitors here.
ViralPulse — covers video and podcast audio
ViralPulse scores the viral potential of a video or podcast before you publish it, with transcription and rewrite suggestions included, and it's the only tool on this list that meaningfully covers long-form audio alongside short-form video.
Who it's for: video and podcast creators or agencies publishing regularly across TikTok, YouTube Shorts, and audio platforms.
Price: free (3 analyses/day, no card required), Creator $7.99/month (120 minutes), Pro $19.99/month (400 minutes); billed via Lemon Squeezy, cancel anytime.
Honest limits: it's billed by minutes rather than per video, which gets expensive at a high publishing cadence, the Pro tier caps at 400 minutes/month, and it's a newer, less-established brand than the dedicated short-form scorers on this list.
Verdict: the clear pick if podcasts or long-form audio are part of your output — nothing else here covers that.
Wallo — computer vision, not just captions
Wallo analyzes both short-form TikTok clips (hook structure, pacing, emotional arc) and long-form YouTube videos (structured, actionable summaries) using actual computer vision rather than just reading captions or metadata.
Who it's for: content creators, marketing teams, and social strategists who need to make sense of long-form video content, not just score short clips.
Price: not publicly listed; the TikTok analyzer and YouTube summarizer are accessible directly on the site.
Honest limits: no public pricing makes budgeting hard upfront, there's less transparency about paid plans than its competitors here, and it's less specialized than a tool built around one format.
Verdict: worth trying because the entry tools are accessible without a paywall visible yet — but confirm actual pricing before building a workflow around it.
Which one should you actually pick?
If you want to fix a weak hook before you ever film, HookMafia is the only tool here built for that. For after-the-fact diagnosis, it comes down to platform: TikTok-only with a detailed 7-part breakdown, CheckViral; multi-platform short-form at the best unlimited price, TikAlyzer; podcasts or long-form audio in the mix, ViralPulse. Wallo is worth a look if you specifically need long-form YouTube summarization alongside short-form scoring, once you've confirmed its real pricing. None of these guarantee virality — they're all pattern-matching against what's performed before, not predicting the future — but they're a faster, cheaper feedback loop than posting blind and waiting for the analytics to tell you what went wrong.
