Crossword Labs Autofill

Solve and grade any Crossword Labs puzzle in one click, using the answers the page already sends to your browser.

Crossword Labs Autofill reads the puzzle solution that the website already sends to your browser, enters every answer into the grid, and lets the site's own grading take over. Why It Exists When a Crossword Labs puzzle loads, the complete solution is sent to your browser. The site's "Answers" button only controls whether that data is shown; your browser already has it. This extension reads that data and fills in the grid to demonstrate the exposure. How to Use It 1. Open any puzzle on crosswordlabs.com. 2. Click the Crossword Labs Autofill icon in your toolbar. 3. Click "Fill and grade puzzle." The grid fills in, your progress is saved the same way the site saves it, and the page reloads to grade your answers. If Something Goes Wrong If a puzzle can't be filled, the popup shows an error code and a "Report this problem" button. It opens a GitHub issue already filled in with the details needed to fix it. You can also use "Report a problem" at the bottom of the popup at any time. Open Source & Privacy The extension is open source and collects no data. It makes no network requests, has no analytics, and only runs on the tab you're on when you click it. Problem reports are only sent if you choose to submit the GitHub issue yourself.
