AI Study Guide audit history

A score change here reflects a detected change in AI Study Guide's Canva Apps listing — the title, description, screenshots, categories, supported languages, integrations, pricing tiers, or support contact were added, removed, or rewritten. AppRanks recomputes the audit every 24 hours from the canonical marketplace listing, so entries marked "no change" mean the listing was identical to the prior snapshot. Score deltas are computed against the immediately prior snapshot only — a long stable run shows as a single "Stable" block below to keep the timeline readable. Section-level diffs are collapsed by default; expand any entry to see exactly which rubric checks moved and by how much.
