in one place.
Write notes, sketch ideas, read PDFs, and organize project files in one workspace. Work locally without an account, with your files on your device.

Drawing
Sketch a diagram, annotate an idea, or write by hand. Choose brushes, colors, and sizes, then move and resize your drawing as your thinking changes.
Notes
Capture thoughts with headings, lists, checklists, and tables. Keep notes as readable Markdown files and search for them when you need to pick up where you left off.
Local by default
Keep notes and project files on your device. Write and draw offline without a cloud account, and back up your workspace folder with your own tools.
Optional Sync encrypts files before upload. It is experimental during beta: keep an independent backup and check Settings → Sync for your current storage limit.
One place for your creative work.
A useful local core stays free.
Keep project notes, sketches, PDFs, and files together. Open a reference beside your notes, then use folders and search to return to your work.
Free to start. Buy Pro once.
