Note cards with summaries and details

Read the short answer before opening the card

Put a definition, conclusion or decision in the summary. Keep calculations and explanations in Details. Adjust the number of columns or show full summaries while browsing the notebook.

For studying, review mode hides the answer and returns forgotten cards to the queue. You mark which answers you remembered yourself.

Tables and code alongside your explanations

Select text to open formatting or type / on an empty line. Add headings, lists, checklists, quotes, dividers and tables. Add rows and columns, merge cells and drag column edges to resize a table.

Code blocks have highlighting, automatic or manual language selection and a copy button. Copying also works when reading a card, including through a shared link.

Use notebooks for topics and tags for collections

Separate materials into notebooks and add colored tags. Each notebook has its own tag catalog, so course topics stay separate from another project’s labels.

Search finds text in headings, summaries and details. Save a tag-filtered collection as a bookmark to open it again later.

Keep sources, record links and earlier text

Link a card to another card, note, planner task or workout. The target receives a backlink. A reader can see the connection only when they can access both records.

History below Details shows authors and text comparisons. It retains up to 50 earlier versions for 7 days. Consecutive saves by one author less than 5 seconds apart are grouped into one version.

Share one card for viewing, or invite editors to collaborate on a notebook. Text and participant cursors update in real time during shared editing.
