Robot CAPTCHA

Training playground

Choose a challenge or run a training session.

Screen coordinates and distances in pixels.

Training settings

Tap accuracy practice

Aim, measure, retry. Harder zones get more practice, just like the arm's practice loop.

This measures screen touches. It does not move or teach the arm. Robot practice stays on its local feedback page.

Practice with real captures

Upload the straightened image from ./lr see, or take a camera photo of the screen. Save the original frame, ask captchasolver, and compare its answer.

A raw camera photo may need straightening first. Include the whole image challenge and its banner. These controls never move the arm.

Automated capture

Stopped. Enter credentials below, then start.

PNG, JPEG or WebP, up to 8 MiB. Credentials are used for the request and are not saved. Choose the expected challenge only when it matches the captured frame.

No frame selected.

Download all practice data

Export every saved session, raw touch, attempt, outcome, solver comparison, and original capture as one JSON file.

Compare the image grid with captchasolver

Open an image challenge, then compare its visible photos with the solver. This checks tile recognition; it does not press tiles or move the arm.
