"ChessRecall completely changed how I study openings. I went from forgetting lines after two days to retaining them for weeks. My Lichess rating jumped 150 points in two months."
"The Explorer mode is gold. Seeing what players at my rating actually play in every position is incredibly useful. I finally understand the openings I'm studying, not just memorizing them."
"I've tried Anki, Chess Tempo, everything. Nothing sticks the way ChessRecall does. The FSRS algorithm is genuinely smarter. I do fewer reviews and remember more."
