About ABWatcher

ABWatcher crawls 1,000+ curated brands daily, detects live A/B tests using vendor SDK fingerprints and page diffs, and surfaces plain-English hypotheses and takeaways for each experiment. It also generates ranked A/B test plans for your own site, grounded in real detections from the pool. It is built for growth and CRO teams who want to stop guessing what to test next.

What makes it different

Unlike CRO blogs or manual competitor screenshots, ABWatcher uses isolated browser fingerprints and vendor SDK probes to catch actual live experiments, then uses a vision model to explain each test in plain English. It connects those real-world detections directly to ranked test plans for your own pages.
