How JJ Notes works in simple words.
No complicated onboarding, no mandatory sign-up, and zero setup friction.
Open & Capture at the Speed of Thought
Open JJ Notes in your browser and start typing immediately. Hit ⌘J to dictate voice, or use / in the block editor for tables, math formulas, checklists, and voice memos.
Organize Projects & Daily Sticky Notes
Group notes by workspace or topic. Pin spontaneous thoughts and urgent todos to your daily color-coded stickies board, and jump anywhere across your notes in milliseconds using ⌘K instant search.
Amplify with AI & Connect Multiple Devices
Turn meeting transcripts into summaries, decisions, and tasks. Ask AI questions about your documents, or sign in to seamlessly sync your notes across different systems (laptop, work computer, phone, tablet) with encrypted Supabase cloud backup.
When should you create an account?
By default, JJ Notes works 100% locally and privately without an account. You only need to create a free account when you want to sync your notes across different systems (work laptop, home PC, phone), collaborate with teammates, or maintain automatic encrypted cloud backups.
