Direct answer

What is PDF Max?

PDF Max is the durably source-grounded pdf workspace for serious professional work and learning. Every passage you keep stays connected to the page it came from, so a conclusion, a presentation, or a deliverable can still be checked against its evidence months later. It also contains the complete PDF toolset required to finish the job—creation, editing, annotation, forms, OCR, conversion, organization, redaction, protection, presentation, and delivery.

One durable workflow

The document is where the work begins.

Move from source material to connected knowledge, then use that same evidence to study, present, export, or deliver a finished document.

  1. Documents

    Create, edit, read, annotate, OCR, fill, protect, and organize the source itself.

  2. Workspace

    Turn exact passages and regions into connected, source-linked knowledge.

  3. Study or Present

    Practice what you need to remember or shape Frames into a live explanation.

  4. Verifiable output

    Export, present, save, or share work that still has a path back to its evidence.

The Workspace advantage

Build the argument without losing the evidence.

Capture passages, markup, comments, images, tables, formulas, and notes as Cards. Every Card retains a route to its exact page source while you search, tag, filter, connect, arrange, and gather ideas into Frames.

  • Compare multiple PDFs in one included Workspace without merging the files.
  • Turn Frames into a live presentation that keeps your source material close.
  • Export research to Markdown with Pro, or to Markdown, PDF, and Word with Premium.

Professional workflows

One product. Different high-value outcomes.

PDF Max adapts to the work around the document. These are workflows over the same product—not separate editions or disconnected vertical tools.

Researchers and academics

Build a synthesis you can trace.

Compare papers, preserve passages, tables, figures, and formulas, and return to the exact page before you cite or conclude.

Legal, policy, and compliance reviewers

Keep every conclusion attached to evidence.

Map supporting and conflicting material, review requirements and clauses, then redact or protect the copy you deliver.

Consultants and analysts

Move from source pack to defensible brief.

Organize multi-document evidence into Frames, explain the reasoning live, and export the same accepted knowledge.

Students and educators

Turn course material into active recall.

Create Questions from source-linked Cards, practice on a schedule, inspect Progress, and revisit the original explanation.

Individuals and operations teams

Finish the document without a handoff chain.

Scan, complete forms, edit content, organize pages, sign, optimize, protect, and send the finished PDF.

Study included with Free

Turn course documents into knowledge you can understand, recall, and use.

Turn source-linked Cards into reviewable Questions, practice on a schedule, inspect Progress, and return to the original evidence whenever an answer needs context.

  • Author Questions manually, with optional Apple Intelligence drafts on supported devices.
  • Separate scheduled Study from practice sessions that leave the schedule unchanged.
  • Inspect recall, lapses, workload, and upcoming reviews for each Question's own history.
