Everything dotPen does.

Read what your agents write, see what changed, and send your notes back. Here's every part of it.

Change marks

Struck words, new lines in green, and a tag where lines were cut.

A plan with an agent's edits marked: a struck word replaced in green, a changed percentage, and a tag where a line was removed

Dots and pencils

A green dot on new files, and a pencil that moves while an agent writes.

Margin comments

Select a line, press C, and leave a note beside it.

Two comments in the margin of a plan, each beside the line it points at

Send to Agent

One prompt with your comments, the exact lines, and what changed.

The Send to Agent sheet, turning comments into one prompt with the exact lines they point at

Diagrams and math

Mermaid, LaTeX and highlighted code, on a white, paper or night page.

⌘K palette
