01 · Detect

We sweep your niche every morning.

Describe your niche and that's it: you don't have to arrive with a list. Every dot is an account the sonar looked at today, and most of them are accounts you didn't know existed, working right now in your niche.

02 · Measure

We don't look at views.

We built our own algorithm that detects when a reel is blowing up right now, not once it has stopped being a trend. That's the Sonar Factor. How we calculate it is ours and we don't publish it: what matters is that it's not a view threshold or a follower ratio.

03 · Break down

We hand it to you broken down.

Hook, structure, pace and why it gets shared. All you have to do is film it.

The problem

You're not short on consistency.
You're short on information.

You film, edit, post. 800 views. And back to square one with no idea what went wrong. The cost isn't the forty minutes that reel took: it's the three weeks you lose testing formats that were never going to work.

Meanwhile, someone in your niche with fewer followers than you just did 90,000 views with an idea you could have filmed on Tuesday.

Without sonar

Post and pray

The usual loop: brainstorming, gut feel and the odd screenshot of a competitor.

  • Ideas out of thin air, or from one stray reel, with no data behind them
  • You hear about the trend when it's already in your feed: too late
  • 5 reels a week hoping one lands
  • Result: the same views as always
With viralsonar

Detect and replicate

Someone else already took the risk. You show up with the format already proven.

  • You see the reel from a small account with a high Sonar Factor in your niche
  • You understand why: hook, structure, length, audio, caption
  • You adapt it to your voice and style, and record
  • Result: proven format, better performance
Inside the product

Your niche, under watch.

You open the dashboard, hit «run» and see which reels are taking off, how fast they're growing, how to replicate them and which trending audios are spreading between accounts.

Viral reel radar

Every scan surfaces the reels breaking their own ceiling in your niche, ranked by Sonar Factor. The flame marks the formats worth studying.

Discover

The most-watched reels in every sector on Instagram, plus what's happening just outside your niche.

Winning Formats

Replicable video ideas grouped by AI from real outliers, in Spanish and English. Trending formats and evergreen ones that still work 30 days on.

Why it works

Every outlier comes broken down: hook, structure, pacing and why it gets shared. You read it in a minute and go shoot.

Timing

By the time you see it in your feed, you're already late.

By the time a format shows up in your Explore, it's been circulating for two weeks and three hundred accounts have copied it. The algorithm has seen it. So have you. The key is the first three or four days.

viralsonar alerts you here · day 1 You see it in your feed here · day 9 Your window: days 1–4

Day 1: Viralsonar scans that day. The first reel to break its ceiling shows up on your dashboard that same morning. You've got an «Outlier»: try it if you like.

Days 2–4: accounts start replicating the same format. The algorithm is rewarding it and the audience hasn't seen it a thousand times yet. We've got a winning format you can replicate.

Day 9+: the format is in every feed and reach collapses. Whoever joins now is late; you've already posted.

FAQ

Frequently asked questions.

You don't copy the video. You replicate the format: the structure, the type of hook, the angle. That's what the content industry has always done: nobody invented «three mistakes you're making», but it works in any niche. Viralsonar tells you which of those structures is working right now in yours. What you film on top of it is yours.

Yes, and that's where it shows most. During onboarding you describe your niche in one sentence, as specific as you like: «physiotherapy specializing in plantar fascia» works perfectly. Viralsonar starts from the reference accounts you give it and keeps discovering new ones through related accounts, keywords and shared audio.

No. Viralsonar analyzes public content. We don't ask for your password, we don't post for you and we never touch your account. Your profile is at no risk.

On Creator and Pro the radar scans on its own every morning while you use the app, and emails you what's new. On Free you get one full scan a month, which you launch whenever you want from the dashboard. On every plan you can run it by hand whenever you feel like it, within your quota.

Yes. For every friend who signs up with your link and adds their card, you both get one extra scan each, single use: it's spent the day you run out of scans. Up to 10 banked. You'll find it on your dashboard, under My account.

A hashtag sorts by absolute popularity, so it always shows you the same big accounts. Viralsonar looks for the opposite: accounts performing far above their own normal. That's where the replicable format shows up. And it groups them by pattern and explains why they work, which is the part that really eats your afternoon.

Yes. When an audio starts jumping from one account to another inside a niche, it's the earliest signal there is that something is about to blow up. It's one of the dashboard's sections.

Yes. The analysis doesn't depend on the video's language but on how the metrics behave and on the niche you define. And the interface is available in Spanish and English, with bilingual format cards.

Viralsonar is Instagram only, on purpose. If your plan is to grow on Instagram, the tool you want is the one that only looks at Instagram. The audience isn't TikTok's and doesn't behave the same way, and neither does what you build on top of a reel: ManyChat keyword-to-DM flows, comment automations, the path from reel to profile visit to follow. A format that works on TikTok can land flat here, and the other way round. Everything a scan brings back is already in the context you're going to publish in.

Yes, on the paid plans. Any reel the radar finds, you take with you: the video as MP4, the audio as a file and the transcription as .txt. The hook becomes text you can edit, and the sound a file you drop into your own edit.

Yes, from your dashboard in two clicks. No commitment, no retention call, no forms. During the trial we email you two days before the charge, so you can decide in time.

That's what the trial is for: you can use Creator free for 7 days and check it against your own niche before paying anything.
