An IDE in your code blocks: smart Enter and indentation, closing brackets, suggestions and templates, coloured brackets and sticky headers; on desktop, checking as you type, quick fixes.
Keep a growing vault tidy: inbox triage, smart folders, colored tags, link suggestions as you type, a vault health check, iCloud conflict fixing, literature notes from arXiv and DOI links.
Type an expression ending in = and the answer appears as you type, with variables, functions, units, conversions, percentages, currency and dates.
Run code blocks in place with live output: a Python notebook with a debugger and variables view, MATLAB, C/C++, Swift and more on desktop, and Python on iPhone and iPad (beta).
On-device AI for your notes: ask your notes, related notes, distill permanent notes, name untitled files, fill in properties, link by meaning, find duplicate ideas, writing help.
