10 best apps to check if a video will go viral in 2026 (rated and compared)
Want your next video to go viral?
Get a free score before you post, plus the one change that helps most.
The fastest way to check if a video will go viral before you post is to run it through an app that scores it. A good one watches your reel the way the feed would, rates the parts that drive views, and tells you what to make stronger. The catch is that most apps people call viral checkers are built for a different job: some clip long videos and rank the pieces, some are made for YouTube, and some only show numbers after a post is already live.
So we compared 10 of the most popular apps for rating videos and put them in order for one clear job: checking the short video you are about to post. Here is the full ranking, what each app is actually best at, and how to pick the right one for you.
What makes a good video rating app
Before the ranking, here is what separates an app that truly helps from one that just shows a number. The best video rating apps do four things: they look at the actual reel you filmed, they score the parts that decide views like the hook and whether people keep watching, they hand you clear fixes you can act on, and they do it before you post so you can still improve the video. Keep those four in mind as you read, and the right pick for you gets obvious.
The 10 best apps to check if a video will go viral
We ranked these by how well they do that one job: rating the short video you are about to post. Tools that clip long videos or focus on YouTube still earn a spot, because plenty of creators use them, and it helps to know exactly what each one is built for.
| # | App | Best for | Why it ranks here |
|---|---|---|---|
| 1 | ReelReady | A pre-post virality check on your reel | Our pick, and the only one built just for this. It scores the exact reel you are about to post on all 7 things and hands you a clear fix for each, so you improve it and post your best every time. |
| 2 | Quso.ai | An all-in-one short-video toolkit | Comes closest. It can score an uploaded reel too, though it juggles many jobs, so the score is one feature among many. |
| 3 | Opus Clip | Turning a long video into clips | The best-known viral score, but it rates clips it cuts from a long video, so it suits people who already have long footage. |
| 4 | Klap | Clipping podcasts and talks | Solid clip scoring, made for podcasts and talks, so it fits people who make long videos best. |
| 5 | StreamLadder | Streamers and gamers | Great clip scores, tuned for streams and gaming, so it is a niche fit for everyday reels. |
| 6 | Predis.ai | Planning posts ahead | Predicts a post before you make it, which helps with planning more than checking a finished reel. |
| 7 | Munch | Repurposing long content | Good at finding viral moments inside long content, so it shines when you have a long video to cut. |
| 8 | Submagic | Captions and quick polish | More of a polish tool. The captions and edits help a lot, with only light scoring on top. |
| 9 | vidIQ | YouTube creators | Excellent for YouTube titles and search, so it is a better fit there than for reels and TikToks. |
| 10 | Metricool | Seeing what worked after posting | Shows what worked after you post, so it helps you learn for next time rather than check before you share. |
A closer look at the top picks
ReelReady sits at the top because it is built for one job: the check you run right before you post. You upload the short video you are about to share, and it scores your reel on the 7 things that move views: the hook, whether people keep watching, whether they comment, whether they share, how relatable it feels, the visuals, and the sound. For each one you get a plain fix, so you can improve the video and post your best version. It is made for women creators who want to grow, and it tracks your scores over time so you can watch yourself get better.
Quso.ai is the closest all-rounder. You can drag in a reel and it rates its viral potential with tips, and it also clips long videos and schedules posts. If you want one toolkit for lots of jobs, it is a strong pick. The score is one feature among many, so it reads a little less like a focused coach for the video in front of you.
Opus Clip is the name most people know for a virality score. You drop in a long video and it cuts short clips, then gives each clip a score from 0 to 100. It shines when you already have long footage to mine. If you film reels from scratch, it scores the clips it makes from your upload.
What a good pre-post check should do
- Look at the real short video you filmed, start to finish
- Score the hook in the first 3 seconds
- Check whether people would keep watching to the end
- Check whether people would comment and share it
- Give you a clear fix for each weak spot, in plain words
- Work before you post, while you can still improve it
- Track your scores over time so you can see yourself grow
Check the video first, then write the caption
Score and improve the video itself before you spend time on captions, hashtags, or the perfect cover. The video does most of the work in the feed, so fixing the hook and the pace pays off far more than any caption tweak.
How to check your reel before you post
- 1
Film and edit your reel as usual
Make the video you planned. Keep the first few seconds strong and trim any slow warm-up before you run the check.
- 2
Score it before you share
Upload the finished reel to a pre-post checker and let it rate the hook, how much of it people watch, comments, shares, and the look and sound.
- 3
Fix the weakest thing first
Start with whatever scored lowest. Usually it is the hook or the pace, and a small change there moves the most views.
- 4
Re-check, then post your best version
Run it once more to confirm the fix landed, then post. Over time your scores climb, and so does your reach.
A score with no fix is just a number
Plenty of apps hand you a virality score and stop there. A number tells you something is off, but it does not tell you what to change. Pick a tool that pairs the score with a clear fix, so each post goes out a little stronger than the last.
FAQ
Is there an app to check if a video will go viral?
Yes. A pre-post checker scores the short video you are about to post on the parts that drive views, like the hook and whether people keep watching, then shows you what to improve before you share. Some apps instead score clips they cut from a long video, and others are built for YouTube. Pick one that rates the actual reel you filmed.
How accurate are viral video score apps?
They are a strong guide, not a crystal ball. A good app catches the common reasons a video gets fewer views, like a slow hook or a flat ending, and those are the things you can actually fix. No tool can promise a video goes viral, since timing and luck play a part. Use the score to ship a stronger video every time, and your odds add up.
What is a virality score?
A virality score is a single number an app gives your video to estimate how likely it is to get views and shares. It usually blends the hook, how much of the video people watch, and how shareable it feels. The number on its own is just a signal. The useful apps pair it with clear fixes, so you know exactly what to change to raise it.
Can I tell if a reel will go viral before posting?
You can stack the odds in your favor. Watch it back like a stranger scrolling fast: did the first 3 seconds stop you, did you watch to the end, would you share it? A pre-post app does this for you and scores each part, so you can improve the weak spot first. You cannot guarantee viral, but you can post your best version every time.
Are these apps free?
Most offer a free trial or a small free tier, then charge monthly once you use them often. Clipping tools tend to price by minutes of video processed, while pre-post checkers price by how many videos you score. If you post a few reels a week, a low-cost plan usually covers it. Start on a free option to see which one fits how you work.
Which app is best for short videos like reels and TikToks?
For checking a reel before you post, the best fit is an app that rates the finished short video itself and gives you fixes, rather than one that clips long footage or focuses on YouTube search. If you repurpose long videos instead, a clipping tool with a virality score helps too. Match the app to the way you actually make your videos.
