Ostrol
What Ostrol is
Ostrol is a web-based math solver for learners and educators. Users can type or paste a problem, photograph it, or upload a PDF; signed-in users can upload PNG, JPEG, WebP, or PDF files for text extraction. Ostrol describes coverage from arithmetic through multivariable calculus, including linear algebra, statistics, probability, discrete math, and word problems. Solutions provide step-by-step reasoning and may include a separate symbolic check. Checks are labeled verified, unverified, unverifiable, or mismatch, and a verified result is not a guarantee of correctness. The free plan costs nothing and includes two solves per month without a credit card. The interface supports English and French. Signed-in solutions are private by default and become public only through a share link. Approved school pilots include role-based workspaces, classes, assignments, student enrollment, and CSV roster import.
