Field notes
The homepage lays out a three-step interaction: write with Apple Pencil, lasso a line or problem, then request a check. It describes three outcomes—“checks out,” “look here,” and “can’t verify yet”—and says uncertain symbol recognition can be reviewed before a check runs. Chalk, graphing, and study features are also presented, while the page invites visitors to join a waitlist; these are product descriptions, not independently verified app behavior.
