Features
One page, every tool.
Brainstorm brings writing and drawing together in a single native surface. Here is what you can do on a page.
01
Hand-drawn shapes and freehand
Draw naturally and hold at the end of a stroke to snap it into a clean rectangle, ellipse, line, or arrow. Everything renders in a warm, hand-drawn style, so a rough sketch and a tidy diagram live on the same page.
02
Live Markdown with code blocks
Headings, lists, quotes, and links format live while you type. Fenced code blocks get real syntax highlighting, so notes, snippets, and explanations sit right next to your drawings.
03
Native LaTeX math and plain-words shorthand
Type LaTeX for full control, or use the plain-words shorthand and let Brainstorm turn "x squared plus 1 over 2" into a typeset equation. Math is rendered natively, no browser required.
04
Step-by-step math solver
Type an equation and Brainstorm solves it step by step, with exact fractions and worked reasoning, across algebra, calculus, trigonometry, and more. It runs entirely on-device, so there is no cloud call and nothing to guess, just the maths shown in full.
05
Inline images with trace-to-sketch
Bring in photos and diagrams inline, then trace-to-sketch turns them into hand-drawn line art that matches the rest of your page. Great for redrawing a reference or simplifying a screenshot.
06
Import PDFs and photos, with OCR
Import a PDF or image as pages to annotate, or let on-device OCR pull the text out into an editable note. Scanned handouts and snapshots become real, searchable notes without retyping, all on your device.
07
On-device recording and transcription
Capture a lecture or meeting and get a transcript powered by whisper, running entirely on your Mac. The audio never leaves the device, so private conversations stay private.
08
Page themes with matched ink
Switch a page between chalkboard, whiteboard, paper, graphite, and blueprint. Each theme comes with an ink palette tuned to look right on that surface, so pages always read cleanly.
09
Print and PDF export
Pages are laid out as printable sheets, so you can print directly or export a crisp PDF to hand off, submit, or archive without any reformatting.
10
Privacy-first diagnostics
Nothing phones home unless you opt in. Diagnostics are off by default, everything runs on-device, and there is no web view embedded in the app. Your notes and audio stay with you.
