Research belongs near the draft.

PDFs often hold the facts, quotes, examples, contracts, class readings, forms, and reference material that shape the writing. LiquidWorkspace keeps that material close to the editor instead of sending it to a separate app window.

PDF work inside the project

  • Import PDFs from Finder or the file picker.
  • View PDFs in the main editor, side panes, or Rogue Editors.
  • Add highlights, underlines, comments, and freehand ink.
  • Fill PDF forms, save them, reopen them, and export filled copies.

Turn reading into notes

  • Create notes from selected PDF text.
  • Send useful passages to Liquid Clipboard.
  • Copy quotes and source references.
  • Export annotated PDFs when you need to share or archive them.
LiquidWorkspace with PDFs open on both sides of the writing workspace

A workspace for PDF-heavy writing.

Students can keep readings beside assignments. Researchers can mark sources while drafting. Teachers can review handouts and notes in one place. Writers can keep reference PDFs close without losing the thread.

Students

Keep class readings, notes, assignments, and drafts in the same workspace.

Researchers

Annotate sources, extract useful passages, and keep references tied to the project.

PDF-heavy workers

Fill forms, review documents, and export annotated copies without leaving the writing room.

LiquidWorkspace is built independently, from the writing desk outward - shaped by real writing, real notes, real PDFs, and the need for a workspace that can change with the work.
