Notes that link
Plain-Markdown notes with real backlinks. Reference one note from another and jump between them — your knowledge stays connected, not siloed.
Study Concise
Notes, PDFs, and drawings — linked. Local-first, on every device.
Android app launching soon on Google Play.
Annotate PDFs
Open a PDF and draw, highlight, and mark it up page by page. Your annotations live alongside the document, never baked destructively into it.
Draw freely
Freehand drawing notebooks with grid, lined, or blank pages — for diagrams, sketches, and working things out by hand.
Everything connects
Circle a region of a PDF or drawing and paste it into any note as a live link. Click it to jump back to the source; the link works both ways.
Find anything
Full-text search across every note and the text of every PDF, so the thing you wrote weeks ago is one query away.
Sync across devices
Work on your phone, sync, and pick up on your desktop. Your library syncs through your own Google Drive — newest change wins, deletes carry over.
Your notes stay yours
Study Concise is local-first: your notes, PDFs, and drawings live on your device. Optional sync uses your own Google Drive and a permission that lets the app see only the files it creates — nothing else in your Drive, and nothing sent to us.
