Short answer
Lazyweb Research detected 77 distinct experiments at Brainly (July 2026), evenly split between paywall (at least 10) and signup (at least 10). source[1] The detected direction is pricing transparency on the trial paywall and reframing the entry screen around joining rather than re-authenticating. source[2] These are observed variations with inferred rationale, not confirmed A/B tests.
Lazyweb Research detected 77 Brainly experiments (July 2026), including a Brainly+ paywall that added explicit post-trial pricing under the 7-day-trial CTA.
The finding
Lazyweb Research detected 77 distinct experiments at Brainly, with paywall (at least 10) and signup (at least 10) both represented. source[1] Brainly iterates the two ends of its funnel — acquisition and monetization — at comparable volume, making it a useful two-surface case study for an education app.
What actually changed
On the paywall (2026-01-28), the Brainly+ screen added an explicit post-trial monthly price and cancel-anytime copy directly under the 7-day-trial CTA, with the headline and CTA unchanged — inferred rationale: pricing transparency reduces trial anxiety without weakening the offer. source[2] On signup (2026-01-28), a return-login screen ("Welcome again," username + password, LOG IN) was replaced by a "Join Brainly Community" email-first SIGN UP screen — reframing the entry point around joining rather than re-authenticating. source[3]
How to apply it
Brainly's paywall change is a clean transparency test: surface the post-trial price and cancel terms under the CTA without touching the headline or the offer. If your trial paywall hides post-trial pricing, this is a low-risk variant to try. The signup change — leading with "join" instead of "log in" for first-time visitors — is a separate acquisition test. Both are detected variations, not proven winners. source[2]source[3]
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 many experiments). source[4]

Methodology
Universe: 77 distinct Brainly experiments within 4,814 detected diffs, July 2026. Extraction: LLM-inferred rationale on observed variations. Caveat: detected variations only, never confirmed A/B tests.
