Alternatives
Junbi does one placement — YouTube pre-roll — with real research pedigree. The usual reason to look for an alternative is simple: your media plan stopped being a YouTube plan.
Specialization cuts both ways. YouTube norms are exactly right for pre-roll and exactly wrong for a sound-on, full-screen, swipeable feed — placements punish creative differently. Teams whose budgets shifted toward TikTok, Reels, and Shorts need benchmarks born in that environment; teams that stayed on YouTube but need higher testing volume run into per-study economics instead.
PreTestAds scores attention against 76 top-performing TikTok ads — creative that won in the most unforgiving feed there is. AdCortex™, trained on fMRI brain-response data, returns a percentile, Hook Strength, drop-off second, and the full engagement curve in minutes, from $49/month with the first analysis free. For TikTok, Reels, and Shorts, that's the benchmark that matches the physics. Head-to-head: PreTestAds vs Junbi.
If Junbi's appeal was research rigor, Realeyes offers the observational version: opt-in panelists watched on webcam, attention and emotion read by computer vision, aggregated into attention scores platforms themselves have used. Panel costs and timelines apply. Comparison: PreTestAds vs Realeyes.
Neurons' Predict covers images and video with eye-tracking-validated attention estimates, heatmaps, and brand norms — a broader, less placement-specific instrument than Junbi, packaged for brands and agencies. Comparison: PreTestAds vs Neurons.
If the questions outgrew attention itself — comprehension, appeal, purchase intent — Zappi's templated panel studies deliver human diagnostics at agile-research pace, with connected learning across studies. Enterprise platform economics apply. Comparison: PreTestAds vs Zappi.
Start from the media plan, not the tool list. Budget still concentrated in YouTube pre-roll → Junbi remains a sensible default. Budget moving into feeds → benchmark against feed winners, and let per-test price decide how much of your creative actually gets tested: at screening prices, the answer can finally be "all of it."
Scored against 76 top TikTok ads, in minutes — first analysis free.
Test Your Ad FreeIf your creative runs beyond YouTube — TikTok, Reels, Shorts — PreTestAds benchmarks attention against 76 top TikTok ads from about $2 per test, self-serve. If you want observed human attention rather than prediction, Realeyes is the panel-grade option.
Junbi is built around YouTube: its norms, benchmarks, and brand-recognition moments are YouTube-native. Feed platforms have different attention physics — sound-on, full-screen, swipe-to-kill — so testing against a TikTok-native benchmark fits those placements better.
You need benchmarks that match the placement's physics. A skippable pre-roll and a swipeable feed punish weakness differently — same creative, different failure seconds. Test against norms from the format where the money will actually run.
