The Missing Link

About

The Missing Link finds the U.S. court case discussed on the page you are reading and links you straight to it on CourtListener.

Click the toolbar button, or right-click selected text. Claude reads the visible page text, identifies the case, and the extension searches CourtListener for the matching opinion, docket, or filing. On a page that discusses several cases, select the passage you care about first to target that one.

WHAT YOU NEED
- Your own Anthropic API key (console.anthropic.com). Light use is usually cents, not dollars, though heavy use or repeated testing can add up
- No CourtListener account is required

MODEL CHOICE
- Sonnet 4.6: balanced, the default
- Haiku 4.5: faster and cheaper
- Opus 4.7: best on difficult or ambiguous pages

PRIVACY
- Visible page text and your selection are sent only to Anthropic, to identify the case.
- Resulting case identifiers are sent only to CourtListener, to find the matching record.
- Your Anthropic API key is stored locally in your browser and sent only to Anthropic.
- No analytics, telemetry, ads, or backend.

Some video-led or heavily script-rendered pages do not expose readable article text. In those cases the extension may say the page is empty.
