Upload two ad variants. AI compares them on 12 dimensions and tells you which one wins, by how much, and why. The best A/B test is the one you didn\u2019t need to run because the loser was obvious.
Predict a winner freeNo credit card. First audit free.
Get a clear verdict: "Variant A wins, 73% confidence" with reasoning. No vibes, no "they’re both fine."
Hook strength, clarity, CTA effectiveness, trust signals, visual composition, copy tone, mobile readability, social proof density, urgency, value signal, emotional pull, scroll-stop power. Each scored for both variants.
Not just "B is worse." Specifically: "B’s CTA is generic: change ‘Learn More’ to ‘See How It Works’. B’s headline lacks urgency, add a deadline."
70% of split tests have an obvious winner before they run. This catches them in 10 seconds. Use real ad budget on tests where the variants are genuinely close.
Compare a Facebook variant against a TikTok variant. AI accounts for platform-specific norms (TikTok hook density, Meta policy strictness, LinkedIn B2B tone).
Upload screenshots of any ad format. The AI reads the visual composition, copy, CTA, and trust elements regardless of medium.
Performance marketers
Run both variants through Predictor first. If the AI says one wins with 75%+ confidence, skip the test and put budget on the winner. Reserve real testing for genuinely close calls.
Solo founders running their own ads
Get an honest second opinion in 10 seconds. AI breaks down exactly what each variant does well and where it falls short.
Agencies presenting to clients
Show the client the 12-point comparison with predicted winner. Concrete reasoning beats subjective "we think this one is better."
It depends on the variants. When two ads are clearly different (one has social proof, one doesn’t), accuracy is very high. When both are well-built and differ only in subtle copy, real A/B testing still wins. Use the predictor to filter out obvious losers, not as a replacement for testing close calls.
No. It eliminates the 70% of tests that were predictable. Real testing is still the gold standard for the remaining 30% where variants are genuinely close. Think of this as triage.
Two at a time. For multi-variant comparisons (3+ ads), use Stakeout (available on Detective tier and up).
The AI says so. If confidence is below 60%, it tells you "real A/B testing recommended: variants are too close to call from creative alone."
Yes. Upload screenshots of key frames or the video itself (Detective tier+). AI evaluates visual composition, copy overlay, and CTA effectiveness.
Cost. A real test on Meta with $50/day per variant for 7 days = $700 minimum. Predictor costs 1 credit ($0.50 on pay-as-you-go). For obvious-loser variants, that’s 1400x cheaper.
