Mark up a document like you would on paper: click to drop a note, drag to highlight a line, scribble with the pen. Place marks across any pages, remove any you regret, then stamp them all in one go.
Notes are embedded as real text — still selectable and searchable in the saved file — and the page's own text is never re-flowed or rasterized.

Frequently asked questions
What kinds of marks can I add?
Sticky notes as real text, highlight bands, and freehand pen strokes — placed anywhere across the document.
Do annotations stay editable text?
Notes are embedded as genuine text, so they remain selectable and searchable in the output; the page’s original text is untouched.
Can I remove a mark before saving?
Yes — marks stay editable until you apply, so you can add and remove freely, then stamp them all at once.
