Short answer
Lazyweb Research detected 18 distinct experiments at Photomath (July 2026), of which at least 14 touch the paywall. source[1] In the CTA dataset Photomath runs 12 paywall CTA experiments, 8 of which changed the CTA text — a paywall-heavy program in the homework-help category. source[2] These are observed before/after variations with inferred rationale, not company-confirmed A/B tests.
Lazyweb Research detected 18 Photomath experiments (July 2026), at least 14 on the paywall, 8 of 12 CTA tests rewriting the button.

The finding
Lazyweb Research detected 18 distinct experiments at Photomath, with at least 14 on the paywall. source[1] In the CTA dataset it runs 12 paywall CTA experiments, 8 of which changed the CTA text. source[2] Photomath is a paywall-concentrated experimenter in the homework-help category, iterating the button copy on two-thirds of its detected CTA tests.
How it compares
Photomath's 8-of-12 CTA-text-change rate is on the higher end of the education cluster, well above Quizlet (2 of 9). It signals a program that treats the CTA wording as a primary lever.
How to apply it
For a homework-help subscription, Photomath is the benchmark for CTA-forward paywall testing — two-thirds of its detected CTA experiments move the button copy. Pair a copy test with an offer test to attribute movement. All are detected variations, not proven winners. source[2]
Caveats
All figures are observed variations with LLM-inferred rationale, not company-confirmed A/B tests — no lift is measured. source[1] Surface splits are lower bounds (screen category unlabeled on 1,425 of 4,814 experiments). [cat_null] CTA claims use the 795-experiment CTA dataset. source[2]

Methodology
Universe: 18 distinct Photomath experiments (12 CTA experiments) within 4,814 detected diffs / 795 CTA diffs, July 2026. Extraction: LLM-inferred rationale on observed variations. Caveat: detected variations only, never confirmed A/B tests.
