The fact check, beside the post you’re reading.

What it does

• Shows the check for the post you’re on

  If Polygraph has checked the post, the panel opens its check: the claims, their verdicts and the sources. Nothing to search for or paste.

• Checks a post that hasn’t been checked

  Press Check this post. You see the price in credits and your balance first, and nothing is spent until you confirm. The check fills in as it runs.

• Lists the claims already found

  Claims Polygraph has already published from the post are listed in the panel. Each one opens its own page, with its full history.

• Opens the fact-check database

  On any other page, the panel takes you to the fact-check database, so you can search what has been checked.

• Connects in one click

  Click Connect, sign in, approve. No key to copy. Each browser gets its own key, so connecting one never signs another out.

• Tells you when something’s wrong

  Out of credits, over a key’s monthly cap, too many checks at once, or a link Polygraph can’t read — each gets a plain message and the next step.

What it doesn’t do

• It runs no script on the sites you visit, and never reads your feed.
• It sends nothing until you open the panel or press a button. To find a post’s check, it reads only the address of the tab you are on, and only on the six post sites.
• It asks Chrome for two permissions: the side panel, and storage for its key.
• Disconnect from the panel, or revoke its key on your keys page, and it stops working at once.
