No open web browsing, no unexpected content. β€’ Safe for all ages, including young learners β€” no social features, no chat, no ads. Whether you're outfitting a school's device fleet, teaching a chemistry unit, or just need to typeset a formula for tomorrow's worksheet, TeXitor makes rigorous scientific notation approachable β€” without ever compromising on privacy.
