best AI tool for competitor ad research in 2026
Your competitors have already paid for the lessons: which keywords sustain bids year after year, which ad tests survived, which creative angles they keep re-shooting. Competitor research tools let you read those receipts instead of re-buying them.
Our pick is the deepest historical dataset per dollar, by a wide margin.
Eighteen-plus years of competitor keyword and ad-copy history from $39/mo. For search, nothing at the price comes close: every keyword a rival bought, every ad test they ran, and the spend estimates to judge conviction. Treat the numbers as directional and it is a bargain.
▲ WATCH: Google-search focused and estimate-based. Treat spend figures as directional, not exact.

Field questions
What is the best tool to see competitor ads?
For Google search history, SpyFu from $39/mo shows every keyword and ad test a competitor ran. For Meta and TikTok creative, Foreplay from $49/mo organizes the live ad libraries into a searchable research database. Adthena is the enterprise option with AI-search visibility tracking.
Is competitor ad spend data accurate?
It is estimate-based and directionally useful, not audit-grade. Use it to rank which competitors have conviction on which keywords and to spot sustained bets, and never to reverse-engineer an exact budget.
