Blue Scribbler

Scribbler keeps your notes and your PDFs in one place. Write notes in a fast plain-text editor with markdown, code blocks, and [[wiki links]] between them. Import the PDFs you actually work from — lecture slides, problem sets, sheet music — and annotate them with Apple Pencil. Everything files into the same folders, so one folder holds a course's notes and its readings together. NOTES • Plain-text editor with markdown and syntax highlighting • Nested folders, pinning, and archive • [[Wiki links]] connect related notes • Full-text search across everything you've written • Checklists that stay checked PDFs • Import from Files, or share straight from Safari • Annotate with Apple Pencil — highlight, draw, sign • Marks are saved into the PDF itself, so they travel with the file • Collections group PDFs for an exam, a gig, or a project • Full-screen reading mode with swipe-to-turn pages…
