Why it is different

What makes PreViral different?

PreViral is built for one job: pre-production video scoring, predicting whether a video will work before you film it. It studies what wins and what flops in your exact niche, on your platform, in your country, across more than 2,500 hours of research. It is specialized, not a general chatbot you ask for an opinion.

It covers both AI and non-AI niches.

Specialized, purpose-built. Computer vision that reads the real video frames.

The score

How does PreViral score a video?

Give PreViral your idea or your finished video. It compares it to what works in your niche and gives you a score from 0 to 100, with the reasons. Green means go. Red means fix these first.

The workflow

What’s the full PreViral workflow?

PreViral walks with you from first idea to final upload. You see what is already working in your niche, check your idea before you film, turn it into a ready-to-shoot script, fix the weak spots in your finished cut, and check your thumbnail’s click appeal, all in one place.

The checklist

What should you check before posting a video?

What should you check before you post? Your hook, your pacing, your payoff, your captions, your thumbnail, and your AI label, the same things that decide how far a video travels. PreViral checks all of this for you, scoring your idea before you film and your finished cut before you post, across its 10 frameworks, so you can fix the weak spots first.

PreViral checks all of this for you. Here’s what it looks at.

  • Hook & Open

  • Does the very first frame grab attention, not a static title card?

    Hook PowerAnalysis

  • Does your hook work even on mute, from visuals and on-screen text?

    Intro FrameworkScore

  • Does the video get to its best moment fast, not save it for the end?

    Strategic OrderingScore

  • Is this kind of video working in your niche right now?

    Curated trendsPulse

  • Pacing & Payoff

  • After the hook, does something keep changing, with no boring stretches?

    Tension & PacingAnalysis

  • Is the length right for the platform (short Reels, mid TikTok, longer YouTube)?

    Tension & PacingScore

  • Is there a fresh payoff every few seconds, with no filler?

    Value LoopsAnalysis

  • Shorts: does the end loop back to the start? Long videos: does it deliver on its promise?

    Payoff & OutroAnalysis

  • Packaging & Compliance

  • Are the captions readable and clear of the on-screen buttons?

    Metadata OptimizationAnalysis

  • Is your title or caption built around the words people search?

    Metadata OptimizationBlueprint

  • Does your thumbnail pop and read clearly at small size?

    Metadata OptimizationVisuals

  • If it’s AI, did you add the platform’s AI label?

Questions

Still have questions?

How is PreViral different from vidIQ or TubeBuddy?

vidIQ and TubeBuddy work on videos you have already published, doing keyword research, tags and channel analytics on what exists. PreViral works one step earlier: it scores your idea and your finished cut before you post, against what is winning in your exact niche. They are complementary. Keep them for tags and channel housekeeping, and use PreViral to decide what is worth making.

Does it work for AI videos?

Yes. PreViral covers both AI and non-AI niches, and its computer vision reads the real video frames either way. It also reminds you to add the platform’s AI label when your video is AI-generated.

Is it free?

There is a free tier that scores your idea and shows the headline number. Paid plans (Lite, Pro and Growth) unlock the full breakdown: the reasons behind the score, niche trends, scripts, finished-cut analysis and thumbnail testing.

How accurate is the score?

The score is a data-informed prediction, not a guarantee. It is built on more than 2,500 hours of research into what travels and what flops across 57 niches, 5 platforms and 30 countries. Treat it as a strong signal and a to-do list, and you still decide.

Do I need to finish my video first?

No. Score works on just the idea, before you film. Analysis works on the finished cut, with timestamped feedback. Most creators check the idea first, then run the final video through Analysis before they post.
