Folio Writer

Folio Writer is a structured writing studio for papers, theses, books, and other long projects. Build a manuscript from small, movable documents, write in Markdown or Typst, and keep working across iPhone, iPad, Mac, and the web.

WRITE ANYWHERE
• A Markdown format bar puts headings, emphasis, lists, links, citations, and math within reach.
• Focus Mode, typewriter scrolling, adjustable text size, live word counts, and writing goals help you stay in your flow.
• Preview a document as you write, or assemble the whole manuscript and save or print it as a PDF.

ORGANIZE YOUR PROJECT
• Keep chapters, notes, research, references, templates, and deleted items together in a binder.
• Reorder documents by touch on iPhone; organize with Corkboard and Outline beside the binder on iPad.
• Keep a synopsis and notes with each document, and use templates for repeatable structures.
• Search across your project and filter by label, status, type, or tag.

READ, RESEARCH, AND CITE
• Open PDFs, images, spreadsheets, and Word files from Research.
• On iPad, keep a PDF, figure, or document beside your draft in the Reading Pane.
• Search PDFs, highlight passages, and add notes. Annotations are saved in the PDF.
• Cite from your project’s BibTeX bibliography and preview citations, math, tables, and images as rendered.
• Choose Manuscript, GitHub, or Modern preview styles. Right-to-left paragraphs render in their proper direction.

KEEP YOUR PROJECT IN STEP
• Open Folio projects from Files and locations such as iCloud Drive, or sync with Folio Cloud.
• Changes sync with Folio Writer on Mac and the web. Conflict-safe syncing combines non-overlapping edits and preserves a copy when changes conflict.
• Collaborate on shared projects with co-authors.

FREE TO WRITE
Writing and organizing are free. Folio Pro for iPhone and iPad adds collaboration, comments and review, tracked suggestions, snapshots, templates, and compile to PDF, Word, or Typst through Folio Cloud. Pro is available as an in-app purchase or subscription; subscriptions include Folio Cloud storage.

Folio projects are built from portable Markdown and Typst files. Your work isn’t locked into a single editor.
