A student writes math with a pen, the way they would on paper. Each finished line turns into clean typed math, lined up on a grid with the equals signs in a column. All of the math stays with the student.
Students who understand the math but lose points to the writing. Columns that drift, so it is hard to tell which terms line up. Symbols a teacher cannot read. Signs and terms dropped while copying a line down to the next step. Those are handwriting and working memory costs, not math costs, and they are what this removes.
It was built for one student first, by his dad, and it is being shaped around how he actually works.
It does no math. No solving, no simplifying, no evaluating, no answer checking, no hints, no calculator. This is not a setting that can be switched on. The capability is not in the app, and an automated check fails the build if a library that could do math is ever added.
It also never corrects the student. If a minus sign is dropped, the dropped minus sign stays dropped, because catching it is the student's job and the teacher needs to see that it happened. When the app is unsure what a shape is, it offers choices based on the shape, never based on which reading would make the math work out.
No accounts, no ads, no analytics, no tracking. The work stays on the tablet unless the student chooses to share it. The app uses the internet exactly once, to download the handwriting reader, and then never again. The full privacy policy says so in detail.
Work arrives as a PDF of the student's own handwriting, placed on graph paper, with a header saying plainly that the app converts handwriting to type and does no math. There is a sheet for teachers and IEP or 504 teams with suggested accommodation wording and notes on state testing.
