About this app

Nodus One is one workspace for everything you write and everything you want to remember: class notes, research, side projects and work docs, with flashcards and spaced repetition built in.

WRITE AND ORGANIZE
• Pages with headings, checklists, toggles, callouts, columns, math, code, diagrams and buttons
• Link notes, see backlinks and a knowledge graph, or arrange ideas on an infinite canvas
• Templates, daily notes, reminders and page history

DATABASES
• Turn pages into a database with table, board, calendar, timeline, gallery and chart views
• Filters, formulas and relations between pages
• Automations that update properties for you, and forms anyone can fill in with a link

REMEMBER WHAT MATTERS
• Cards come straight from your notes: questions and answers, terms and definitions, fill-in-the-blank
• Spaced repetition (FSRS) brings each card back just before you would forget it
• Learn, Match, Test, Cards, Rush and Meteor modes, image occlusion and audio clips
• Clear statistics on what you know and what needs work

READ AND STUDY PDFS
• Highlight, draw with a pen, cut out diagrams and make cards from any passage
• Scanned PDFs become searchable and selectable

AI THAT WORKS ON YOUR NOTES
• Write, summarize, explain and translate in place
• Generate study pages and quizzes, ask questions about your notes, fill database columns

WORK TOGETHER
• Share workspaces with roles, edit the same page live, comment and mention people
• Publish a page to the web with one link

BRING YOUR NOTES

Made for students and exam prep, language learners, researchers, teams and anyone who wants to learn and work in one place.
