A check means the provider offers that feature. Standard (non-promotional) prices from each provider's own site, 7 August 2026; Kaplan and Manhattan Prep don't publish base prices. The big platforms lead on question-bank size and video courses, which this table doesn't try to match — it highlights where Keiko is different, not a full feature-by-feature comparison.
