How it works

1. Name your colors

Turn yellow into "Key facts", green into "Citations to add", purple into "Questions". Your names stay with you across every document.

2. Highlight in one click

Select text, click a named highlighter in the sidebar. No digging through the color picker every time.

3. Harvest

One click gathers every highlighted passage into a list grouped by color, in the order it appears. Copy it, or insert it at the end of the doc.

Why not the free one?

The most-installed highlighter add-on asks for permission to see, edit, create, and delete all of your Google Docs. Highlight Harvest only ever touches the document you have open. It cannot see your other files, and it never sends your document anywhere.

Pricing

$9 one time, per person. No subscription.

Try everything free for 14 days. After that, a license key unlocks it forever on every doc you open. Payments are handled by Polar, which issues your key by email within a minute.
