Best Tools to Find Viral TikTok Formats and Trends in 2026

Volume is the best pick for formats to copy, and the only one on this list that covers TikTok photo slideshows, Instagram carousels and long-running Meta ads together, ranked against each account's own average. It starts at $29.99 a month with a 3-day free trial, and the slideshow editor, agent MCP and TikTok scheduling come with it. Virlo is the strongest paid research tool if you want AI research agents and a data API. TikTok Creative Center is free and comes from TikTok itself, but shows only raw rankings. If you film talking videos and want scripts from outliers, look at Sandcastles.

Prices are monthly, in US dollars, checked November 5, 2026. "Not mentioned" means the company's own site doesn't say.

The Volume Library is a searchable library of TikTok and Instagram posts that beat their own account's average, the formats several accounts share, and the Meta ads brands keep running. A post gets in at 2.5 times its account's average views or more, between 2 and 45 days old, so a small account's breakout sits next to a big one's. Instagram carousels hide their views, so they're compared on likes instead.

It holds about 11,000 posts (including 825 TikTok photo slideshows and 979 Instagram carousels), 1,800 formats and 4,450 Meta ads across 19 niches, updated every day. Each post shows its views against the account's average, then the format, the hook, the first line, why it beat the average, the move to copy, a script and the caption. The same data is public, day by day, on the What's working pages and the Meta ads pages.

Key features:

• Comes with Core and Pro, starting with a 3-day free trial (Google or email, with a card that isn't charged until the trial ends)
• Search by niche, platform, post type and account size
• Your AI agent can search it over MCP: Claude, ChatGPT, Cursor, Claude Code or Codex, 1,000 searches a day
• Make this in Volume opens any post in the slideshow editor, to make your own version and schedule it to TikTok
• Intelligence watches your competitors' posts and Meta ads every week

We checked each tool's own site on November 5, 2026 for what it covers, whether it measures posts against each account's usual reach, whether it covers TikTok photo slideshows, its free plan, its prices, and whether an AI agent can use it. Where a site didn't say, we wrote "not mentioned" rather than guess. Volume is our product, so we've held it to the same test and listed what it doesn't do.
