Highlight a net or part from its text

  1. With Select on, drag across a net name, pin or part number on the schematic to select its text.
  2. In the menu that appears, choose Net annotation or Part annotation.
  3. Give it a title and a comment in the annotation panel, then click Save Annotation.
Tips
  • The same menu has Ask AI, Look up datasheet and Add to trace (see their guides).
  • To copy the highlighted text, press Ctrl + C (⌘ + C on Mac) or click Copy at the top of the menu.

Draw a box around a net, region or part

  1. Click Annotate in the toolbar and choose Net, Region or Part (under Draw a box).
  2. Drag a box on the schematic around what you want to annotate.
  3. The annotation opens in the panel: add a title and comment, then Save Annotation.
  4. Choose the same tool again in the Annotate menu (or Select) to stop.
Tips
  • On a scanned schematic, Cirkit's AI reads the label inside your box and fills in the title.
  • Region boxes are good for whole circuit blocks ("Buck controller", "Input protection").
