READ FIRST. MARK UP SECOND.
Use AI to find the important parts before you start annotating.
For long or unfamiliar PDFs, V13 can help you understand the document first. Summarize key points, translate difficult passages, or review contract language—then use highlights, comments, stamps, and callouts to capture the decisions that matter.
Summarize before highlighting
Get the main ideas first, then highlight the sections worth revisiting instead of marking up every page.
Translate, then comment in context
Understand multilingual content before adding comments or review notes, so annotations stay tied to the document’s meaning.
Review clauses before marking risks
Use AI Contract Review to surface clauses and issues, then add highlights, comments, or stamps for follow-up.
AI CONTRACT REVIEW + MARKUP
Find contract issues with AI, then annotate the clauses that need attention.
Contract review often starts with finding the right clause and ends with human judgment. Let AI Contract Review surface relevant language, then use highlights, callouts, sticky notes, and stamps to capture questions, approvals, and follow-up items directly in the PDF.
Identify clauses faster
Surface important contract language before manual review.
Mark decisions in the document
Highlight risks, add questions, and stamp approval states where they belong.
Keep the review traceable
Use comments and annotation summaries to keep reviewer notes connected to the PDF.
Go beyond annotations with AI Spaces.
Bring related files together, ask questions across them, verify answers at the source, and turn reading into reusable knowledge.

PDF annotation means adding extra information to a PDF without changing the original text. This can include highlights, underlines, sticky notes, shapes, stamps, or drawings. It’s useful for study, collaboration, or reviews.
With PDFelement, you can annotate PDF documents easily on desktop or online, using tools like comments, sticker libraries, and measurement features.
When working with PDFs, it’s important to know whether you need to edit the content or simply annotate it.
