The best ad intelligence tools.
An ad intelligence tool shows you what your competitors are advertising - and, if it's any good, which of those ads are actually proven. Here's what separates the best from the rest, and how the main options compare.
What separates the best ad intelligence tools.
Longevity data, not just a feed
Anyone can show you live ads. The signal that matters is how long an ad has been running - a creative live for 100+ days is proven, not a test. The best tools surface longevity, not just volume.
Creative analysis, not raw dumps
A wall of competitor ads is noise. You need the hooks, formats, angles and persuasion mechanics broken down so you can act - which is analysis, not scraping.
Reconciled to outcomes
Intelligence is only useful if it changes what you spend. The strongest setups tie what competitors are proving to your own blended efficiency and profit, not just curiosity.
Coverage of your category
A tool is only as good as the brands it tracks. Depth in your specific vertical beats a shallow index of millions.
How the options compare.
Meta Ad Library (free)
Best for: A free baseline checkStrengths
Free, official, shows every live ad on Meta.
Limitations
No longevity ranking, no analysis, no export. You do all the interpretation manually, brand by brand.
Ad spy / swipe tools
Best for: Browsing creative inspirationStrengths
Large searchable indexes, filters, saved boards.
Limitations
Built for inspiration, not decisions. Rarely tie back to your account, your margins, or what’s proven to sustain spend.
Mammoth (proof-led intelligence)
Best for: Turning intelligence into profitStrengths
Longevity-ranked winners, full creative analysis, and a team that builds your creative from what’s proven - judged on blended MER and profit.
Limitations
It’s a managed engine, not a self-serve toy - best for brands ready to act on the intelligence.

Ad intelligence FAQs.
What is an ad intelligence tool?
An ad intelligence tool collects and analyses the ads your competitors are running - typically from public sources like the Meta Ad Library - so you can see which creative, hooks and formats are working in your market. The best ad intelligence tools go beyond a feed of ads to show longevity (how long an ad has run), creative analysis, and how to apply it to your own campaigns.
What is the best free ad intelligence tool?
The Meta Ad Library is the best free option - it shows every live ad running on Facebook and Instagram. The limitation is that it offers no longevity ranking, analysis or export, so it’s a manual starting point rather than a decision-making tool. Mammoth’s ad library adds the longevity and creative analysis the free version lacks.
How do I choose an ad intelligence tool?
Look for longevity data (proven ads, not just live ones), genuine creative analysis rather than raw ad dumps, strong coverage of your specific category, and - most importantly - a way to turn the intelligence into spend decisions reconciled to your profit, not just inspiration.
Is competitor ad analysis worth it?
Yes - the longest-running competitor ads are a free signal of what’s proven to convert in your category. Building creative from proven angles instead of guessing is faster, cheaper and lower-risk. The value comes from acting on the analysis, which is why proof-led intelligence beats a passive feed.
