Math and Study Tools

Math and study tools

Work with equations and study materials. Beta 4 has quick math, math blocks, a grapher, flashcards, and study tools. Everything except start-up is untested by hand, so check the test checklist before you rely on a feature.

Math

Feature	Status
Quick math	Built. Type an expression such as 2.5*9.81= and press Space to add the result. One Ctrl+Z removes it.
Math blocks	Built. LaTeX equations as blocks or inline in text.
Equation editing	Built. Edit equations with a pen or keyboard.
Function grapher	Built. A Desmos-style graph with zoom and pan that exports as vector graphics.
Variables and units	Built. Write rent = 1,200, then rent * 12 =, and the result updates. Units work too, as in 5 mi in km =.
Accessible math	Built. Equations carry MathML so screen readers can read them aloud, in braille, or step through term by term. Copy as MathML or LaTeX.
Handwritten math	Built. Handwriting becomes editable equations: fractions, roots, integrals, matrices, and Greek letters.
Mermaid diagrams	Built. Create flowcharts, sequences, class diagrams, and more in Mermaid format.
Mind maps	Built. Create and edit mind maps.

The grapher, quick math, and smart tables use the same calculation engine, so results match everywhere. Math looks the same on screen and in PDF.

Study tools

Feature	What it does	Phase
Flashcards and quizzes	Blocks that you can place in any page	10
Card types	Question and answer, fill-in-the-blank, multiple choice, and image occlusion, which hides part of a diagram	10
Make cards from notes	Build cards by hand, or generate them from a page, a section, or a transcript	10
Inline flashcards	Type a question, ::, and an answer on one line to make a card. Double braces hide words as a blank.	10
Spaced repetition	A schedule shows which cards are due. Decks export to Anki and CSV.	10
Exam dates for decks	Set a date, and the plan spreads new and due cards so you see them all in time. There are no streaks or scores.	10
Deck import	Bring in Anki packages, CSV, and text files, with a report of what was skipped	10
Study tape	Draw tape over ink, text, or an image to hide it, then tap to reveal it. Tape hides content on screen only, and isn't a lock.	10

Generating cards from your notes uses on-device intelligence, which stays off until you turn it on.
