Paragraph-based notes and subnotes
Write notes as regular paragraphs without creating a title or filename first, then add subnotes to build trees of related ideas.
Understory
Understory is a Mac notes and outlining app for students, researchers, bloggers, and other writers. It brings research collection, flexible outlining, Markdown drafting, and publishing into one workflow, with output available as PDF, Rich Text, Markdown, or a website.
Notes, outlines, and drafts in one Mac app
Understory is a Mac notes and outlining app for turning research into finished writing. It is designed for students, researchers, bloggers, and other writers who need to collect source material, organize an argument, draft sections, and produce a shareable document without copying notes between separate apps.
Notes are written as regular text and can be arranged into flexible trees of subnotes. A note can appear in more than one tree, allowing the same research or idea to support different subjects. From an outline, users can select the sections they want to read or publish as a PDF, Rich Text file, Markdown, or website.
Features
Reusable notes across outlines
Place one note in multiple trees without duplicating it. Edits remain consistent wherever the shared note appears.
Search and keyboard navigation
Search as you type, jump from results to a note's place in its tree, and navigate the browser with keyboard commands.
Research attachments and links
Attach PDFs or images to notes, add links in note text, and follow links in both directions.
Research-to-draft workflow
Arrange research beneath the points it supports, write each draft section in Markdown, collapse supporting notes, and read selected main points as a continuous piece with a word count.
Multiple publishing outputs
Publish a selected set of notes or a complete outline as PDF, Rich Text, Markdown, or a website. Earlier versions of notes are retained for review.
Use cases
Collecting reading research
Create a note for a book, add chapter subnotes, and capture quotes or ideas beneath their sources. PDFs and images can be attached to the relevant notes for reference.
Shaping an argument
Build a new outline for an essay or research paper, then place existing research beneath the main points it supports. The source notes remain available in their original tree as well.
Drafting long-form work
Write each section of a paper, article, script, or book in its corresponding note while keeping supporting material visible below it. Collapse the research to review the main points as a continuous draft.
Preparing work for publication
Select individual sections or an entire outline and export it as a PDF, Rich Text document, Markdown file, or website for printing, sharing, or finishing elsewhere.
