We ran 1,300+ searches in 8 viral reel finders. Whose reels do they show?
Our team ran more than 1,300 searches in eight viral reel finders, with the same keywords in each, and saved every result. Whose accounts came back, whether their reels really beat the account, whether search matched the words, and where the creators are.
Type "pilates" into a viral reel finder. What comes back?
If the answer is a reel from an account with two million followers, it can't tell you much. That account gets views on almost anything it posts. But if an account with 5,000 followers reached a million people, the idea did that work, and that's an idea you can borrow.
So the most useful question about any reel finder is a simple one: whose reels does it show you? We set out to answer it. Our team studied eight apps hands-on in October 2026 and ran more than 1,300 searches across the ones with a search box, using the same keywords in each. We saved every result, then ran the same keywords on Aubrium's library.
Aubrium makes this page, and its library is one side of most comparisons here. So we show how each number was measured, and where Aubrium came up short too.
Most reel finders showed small creators big accounts. On the same 147 searches, the typical account in Sandcastles' top results had 125,849 followers; in Aubrium's, 5,607. Many "viral" results hadn't beaten their own account: filtered to Instagram accounts under 100,000, 45% of Viral Outliers' top results did worse than their creator's usual. And search often missed the words typed: half of Virlo's results didn't have the keyword in the caption.
Our team's searches, October 2026. Each tool was measured the way its own search works; how is under "How we did it".
Why we ran this study
Reel finders all promise the same thing: reels that went viral, so you know what to post. But "viral" can mean very different things, and a tool can only show you what it collects.
Four things decide whether a finder is any use to a small creator. Are the accounts close to your size? Did the reels really beat what the account usually gets? Does the search find posts about what you typed? And can you tell where the creator is? A tool's home page won't answer those. Its search results will.
How we did it
We used one keyword list everywhere a tool allowed it: 50 beauty words, 30 general ones, 10 harder ones and 60 niche names from Aubrium's library. For every result we saved the account, its followers, the views, the tool's own score and the caption. Then we ran the same keywords on Aubrium's library, read-only.
Each tool, measured the way its own search works
The tools don't search the same way. One returns posts, another returns accounts, and one has no search at all. So we measured each tool on its own terms, and we say how next to every number.
| Tool | How its search works | What we ran |
|---|---|---|
| Aubrium | A library of viral Instagram posts, each filed by topic into 350+ niches. Its search reads captions and transcripts | The same keywords, on its library, read-only |
| Sandcastles | A global search of captions and titles,2 over the channels its users have added | 149 searches. On 147 of them we kept the top 100 results, sorted by its outlier score |
| Viral Outliers | Covers YouTube, TikTok and Instagram Reels.3 A text search over posts from profiles its users and team added | 147 keywords, three ways: its default view, Instagram accounts under 100,000, and under 10,000. Top 25 results each |
| Octupie | No post search. Its search finds accounts, by name and bio | 220 searches, up to 30 accounts each |
| ViralSpot | No search box. Its AI agent searches an index built from the accounts its users track | 241 searches through the agent, most of them over the last 30 days for accounts with 1,000 to 100,000 followers |
| Virlo | Covers TikTok, Instagram Reels and YouTube Shorts.9 Its chat assistant searches its library | 149 searches for Instagram reels from accounts with 1,000 to 100,000 followers, any date, most viral first. Then 110 runs with one filter changed |
| CreatorHouse | No search. You add accounts to track, or take its suggestions11 | We set out to track 110 small accounts, one at a time |
| Runwave AI | No library: "there is no pre-built catalogue to browse".7 It pulls reels live | Every try came back empty, because its data provider was out of credits |
| ViralFindr | Looks up an Instagram account,10 a hashtag or a word, live | 3 searches, the most its plan allowed |
Because the methods differ, numbers from different tools sit side by side in tables, each with its method, and never in one chart. A few things we left out on purpose. We searched Virlo and ViralSpot inside the 1,000 to 100,000 follower band, so their account sizes aren't comparable to the others. And Sandcastles' captions were saved cut short, so we didn't count how many of its results were on topic.
What we found
Seven findings, each with its numbers and what it means if you're choosing a tool.
Whose accounts show up when you search?
Mostly big ones, except in Aubrium. In the three other tools where we could measure it, the typical account in the top results had more than 100,000 followers.
| Tool | How we measured | Typical account | Over 100,000 | Over a million | Under 10,000 |
|---|---|---|---|---|---|
| Aubrium | Same 147 searches as Sandcastles, top 100 each | 5,607 | None | None | 67% |
| Sandcastles | 147 searches, top 100 each, sorted by its outlier score | 125,849 | 58% | 9% | 6% |
| Viral Outliers | 147 searches, top 25 each, its default view | 212,433 | 69% | 15% | 7% |
| Octupie | 156 searches, up to 30 accounts each | About 224,000 | 65% | 18% | 6% |
"Typical" is the median, the account in the middle. For Aubrium and Sandcastles it's the middle of each search's middle account. Octupie returns accounts, not posts, so its row counts accounts.
Viral Outliers lets you filter by follower count, and that helps. But the filter showed a new problem. Filtered to accounts under 10,000, 41% of what it returned came from businesses, like a spa and a jeweller, rather than creators.
What this means for you: a reel finder's default view is mostly other people's audiences. Look for one where accounts your size are the starting point, not a filter you have to find.
Who do the tools pick for you?
Some tools pick accounts for you, when you sign up or when you ask. Every pick we saw was huge, even when we said the creator was small.
| Tool | What it picked | Their followers |
|---|---|---|
| Sandcastles | A starter watchlist for a creator with under 1,000 followers: 29 accounts, 10 of them brands | 279,000 to 4.9 million |
| Octupie | 10 accounts to track for a new beauty creator, 3 of them cosmetics brands | Median 3.2 million |
| CreatorHouse | Suggested accounts for each niche: 19 lists, 182 accounts | Median 3.8 million. The largest was Cristiano Ronaldo |
| ViralSpot | Suggested accounts for a creator with about 15,000 followers: 8 accounts, four of them brands | 1.8 million to 5 million |
| Aubrium | Nothing to pick: every account in the library has 1,000 to 100,000 followers | None over 100,000 |
For a beauty creator, none of CreatorHouse's 20 suggested accounts had fewer than 100,000 followers.
What this means for you: if a tool builds your watchlist, check who it put there. A list of celebrities and brands will teach you what works for celebrities and brands.
Do the "viral" reels really beat their account?
Not always. Each tool decides "viral" its own way, so we checked each one against its own rule.
| Tool | What its score compares | What we found |
|---|---|---|
| Aubrium | A reel's views against its creator's followers | Every reel reached far more people than its creator has followers. The typical one reached 18 times as many |
| Viral Outliers | Views against the account's own average4 | Filtered to Instagram accounts under 100,000, 45% of top results did worse than their creator's usual. Under 10,000, 60% did |
| Virlo | Views against followers | In 28 of 149 searches, the typical reel in the top 20 "most viral" had fewer views than its account has followers. Of the Instagram reels its research agents collected, 87% (beauty) and 76% (pilates) had fewer views than followers |
| Sandcastles | "a video's views divided by the median views of that channel's videos posted in the 90 days up to that video"1 | 7% of scores were broken: the score was just the view count, and sorting by score put those first. In its newest-first view, 58 of the first 100 pilates results did worse than their account's usual |
| CreatorHouse | Views against the account's median, flagged at 2x or more6 | The same reel scored 0.5 or 1.6 depending on the time window you picked. An account with one post in the window always scored 1.0 |
| ViralSpot | Each post "against its account's normal"8 | Every result was above its account's usual. Its index only returns those |
| Octupie | A post that "significantly outperforms the account's own baseline"5 | Its feed showed tracked accounts' posts above their usual, with a few at only 1.2 to 1.6 times. Its search returns accounts, so there was nothing there to check |
| ViralFindr | No viral score | Nothing to check. It shows likes, comments and views, and its engagement figure was 100 times too small |
| Runwave AI | Views against the creator's usual | Nothing came back to check |
Two different ideas sit behind these scores. Most tools compare a reel with the account's usual views, which shows a breakout for that account. Aubrium and Virlo compare it with followers, which shows a reel that reached far past the people who already follow. Both are fair. What matters is whether the tool's "viral" reels pass its own test, and in Viral Outliers, Virlo and Sandcastles, many didn't.
What this means for you: before you copy a "viral" reel, check its views against the account's followers or its usual views. A tool's own label isn't proof.
How many viral reels can you find from accounts your size?
Where we could line up the same keywords, Aubrium had more, though not on every word.
| Tool | Same keywords, compared | What we found |
|---|---|---|
| ViralSpot | 90 keywords, last 30 days, accounts with 1,000 to 100,000 followers | ViralSpot had 532 posts. Aubrium had more than 4,000. ViralSpot found nothing for 32 keywords, Aubrium for 16 |
| Viral Outliers | 150 keywords, Instagram accounts under 100,000 | Aubrium had more viral posts than Viral Outliers' whole result set on 141 of the 150. Under 10,000 followers, Viral Outliers found nothing for 47 of 147 |
| Octupie | 147 searches | Octupie returned nothing for 22. Aubrium had posts for all 147 |
| Virlo | 60 niche names and 89 keywords, Instagram, 1,000 to 100,000 followers | Aubrium had more viral posts than Virlo had matching reels, at any score, on 49 of the 60 niche names and 46 of the 89 keywords |
| Sandcastles | 147 searches | Sandcastles shows no totals. Aubrium had fewer than 100 matches on 5 of the 147 |
Two honest notes. Virlo had deeper pools for broad words like skincare and real estate, though most of each pool was ordinary reels. And ViralSpot had more posts than Aubrium on 23 of the 90 keywords. Its own agent called some of those off topic, like 21 results for "self tan", none about tanning.
What this means for you: a finder is only as good as what it has collected. Before you pay, search a few words from your niche and count what comes back.
Does the search find what you typed?
Often not. Most tools match something other than the words you typed: a hashtag, a summary, a topic label or a bio.
| Tool | What its search really matches | What we found |
|---|---|---|
| Aubrium | Captions and transcripts, plus posts filed by topic into 350+ niches | A post can match your topic even if the word is only spoken |
| Viral Outliers | Any text that contains your letters | 27% matched only inside a hashtag, and 9.5% only inside a longer word: "cat" matched "education" |
| Virlo | An AI summary of each video | Half the results didn't have the keyword in the caption |
| ViralSpot | Its own AI topic labels | Of results with a caption, 63% had none of the words. "Cat" was read as catering |
| Octupie | Account names and bios | 41% of accounts had every word. "Hair" matched "Chairman" |
| Sandcastles | Words in captions and titles2 | Not counted: its captions were saved cut short |
| ViralFindr | Instagram's own hashtag page, or its keyword search for reels | 38% of its keyword results never used the word in the caption. Its hashtag results had no view counts |
| CreatorHouse | Nothing. There's no search | You type each account in yourself |
The same idea, typed two ways, gave very different answers. We searched "curly hair routine" and "#curlyhairroutine" in four tools.
| Tool | "curly hair routine" | "#curlyhairroutine" |
|---|---|---|
| Viral Outliers | 52 results | 349 results |
| Virlo | 59 results | 21 results |
| ViralSpot | 120 results | None |
| Octupie | 30 accounts, matched on "hair" | None |
Aubrium's niche filing is meant to sidestep this. Each post is filed by what it's about, not just the words in its caption, so browsing a niche doesn't depend on how a creator tagged their post.
What this means for you: search your topic as a phrase and as a hashtag, and see if the results change. If they swing wildly, the tool is matching words, not topics.
Can you see where the creators are?
Only in Aubrium, in practice. A reel from your own country can be easier to make your own, but most tools don't record where a creator is.
Creator country, in each tool
- Yes: Aubrium: the creator's country on 96% of posts, across 200 countries, with a country filter
- Partly: Virlo: a region on 4% of its Instagram results, so its region filter finds little
- No: Sandcastles: no country shown, and no country filter
- No: Viral Outliers: no country data at all
- No: ViralSpot: no country shown, and no filter
- No: Octupie, CreatorHouse, Runwave AI and ViralFindr: no country shown
One thing we learned about our own library. For the 90 English keywords on our list, more of Aubrium's matching creators were in India than in the US: 34% to 29%. Beauty words leaned that way most. If you want reels from your own country, use the filter.
How old are the reels?
Some tools mix in old posts. A reel from 2019 tells you less about what works now.
| Tool | How we measured | Posted before 2024 |
|---|---|---|
| Aubrium | Same 147 searches as Sandcastles, top 100 each | 4% |
| Sandcastles | 147 searches, top 100 each, sorted by its outlier score | 24% |
| Viral Outliers | 147 searches, top 25 each, its default view | 7% |
| ViralFindr | Its hashtag search for #skincare | 5%, and 27% before 2026 |
| ViralSpot | Searches over the last 30 or 90 days | None, by design of the search |
Virlo's research agents also pulled in old videos. Its beauty set, meant to cover this month, reached back to 2022, and its pilates set to 2019.
What this means for you: check the date on a "viral" reel before you plan around it.
What this means for creators
You don't need our data to test a reel finder. A few searches of your own will tell you most of it.
Five checks before you trust a reel finder
- Yes: Look at the follower counts behind the first 20 results
- Yes: Check that its "viral" reels beat the account's followers or its usual views
- Yes: Search your topic as a phrase and as a hashtag, and compare
- Yes: Look for the creator's country, and a filter for it
- Yes: Check the dates on the reels it shows you
- No: Copy a reel from an account with millions of followers and expect it to tell you much
Limits of this study
Here's what the study can't tell you.
- Each tool searches differently, so we measured each one its own way. The numbers sit side by side, and some compare different things: Octupie's search returns accounts, not posts.
- It's one month, October 2026, and tools change. Runwave AI's data provider was out of credits while we tested it, and that may not be true on another day.
- Some plans capped a step. ViralFindr allowed 3 searches. CreatorHouse took 37 of the accounts we tried to add, stopped loading its feed at about 40 tracked accounts and went down at about 59.
- We searched Virlo and ViralSpot inside the 1,000 to 100,000 follower band, so their account sizes aren't in the first table.
- We didn't count how many of Sandcastles' results were on topic, because its captions were saved cut short.
- Aubrium's weak spot here was the newest posts. Its last 30 days were thin for some topics, single digits for pilates, while tools that read accounts live reached posts from the day before. New posts arrive every day, more than 3,700 in the last week.
- Aubrium makes this page, and its library is one side of most comparisons. Its numbers come from its own database, read-only.
Questions people ask
Which viral reel finder shows reels from accounts my size?
Aubrium is built that way: every account in its library has 1,000 to 100,000 followers. On the same 147 searches, the typical account in Aubrium's top results had 5,607 followers, against 125,849 in Sandcastles'.
Are the "viral" reels in these tools real outliers?
Not always. Filtered to Instagram accounts under 100,000, 45% of Viral Outliers' top results did worse than their creator's usual. In Aubrium, every reel reached far more people than its creator has followers.
Why does account size matter?
A huge account gets views on almost anything, so its reels can't tell you which ideas work. When a small account reaches far past its followers, the idea did that, and that's the part you can learn from.
Does searching a hashtag give different results?
In most tools, yes. "curly hair routine" found 52 posts in Viral Outliers, and "#curlyhairroutine" found 349. In ViralSpot and Octupie, the hashtag found nothing at all.
Which reel finder can filter by country?
Aubrium. It knows the creator's country on 96% of its posts and lets you filter by it. Virlo has a region filter, but only 4% of its Instagram results had a region.
How many searches did you run?
More than 1,300, across the tools that have a search box, with the same keyword list in each. Every result was saved, and the same keywords were run on Aubrium's library.

How we did this
The full method is under "How we did it" above. In short: our team studied each app hands-on in October 2026 and ran more than 1,300 searches across the tools that have one, with the same keyword list in each. We saved every result: the account, its followers, the views, the tool's own score and the caption. Each tool was measured the way its own search works. We ran the same keywords on Aubrium's library, read-only, and Aubrium's library numbers come from its own database, read on 23 October 2026. Where a plan capped a step, we used what it allowed and counted only what it produced. What each tool says about itself comes from its own site, read on 22 October 2026. Apps change; if something here is out of date, tell us and we'll fix it and move the date. And yes, Aubrium makes this page.
