Read full description

Monosemy is an AI note app that understands handwriting and sketches. Using AI should not mean stopping to rewrite your thoughts as a separate prompt.

AI that starts with your handwriting • Search the web from questions written by hand and get organized answers. • Solve equations and view step-by-step solutions. • Organize handwritten content into tables. • Create function graphs directly from your notes. • Use your notes and imported materials as context for AI search. Tools that work on the page • View search results and browse the web without leaving your note. • Use calculators, math tools, tables, and graphs alongside your handwriting. • Add maps, calendars, to-dos, timers, and memos to the page. • Pass results between connected tools to continue your work. Bring the materials you already use • Import, read, and annotate PDFs. • Import PowerPoint and Word documents. • Add images and documents to your notes. • Combine handwriting, sketches, materials, and AI results on one page. • Search handwriting and content across your notes. In Monosemy, AI is not somewhere you go after taking notes. It becomes part of the page as you write and draw.
