About this extension

Save time by asking Buster to solve CAPTCHAs for you.

Read the publisher’s full description

Buster is a browser extension which helps you to solve difficult CAPTCHAs by completing reCAPTCHA audio challenges using speech recognition. Challenges are solved by clicking on the extension button at the bottom of the reCAPTCHA widget. It is not guaranteed that challenges are always solved, the limitations of the technology need to be considered. Buster is an open source project made possible thanks to a community of awesome supporters. If you'd like to support the continued development of the extension, please check out https://armin.dev/go/patreon. Client app The success rate of the extension can be improved by simulating user interactions with the help of a client app. Follow the instructions from the extension's options to download and install the client app on Windows, Linux and macOS. Solving more than a couple of reCAPTCHA challenges a day may lead to a temporary block, regardless of your use of the extension. Visit the wiki for more details. https://github.com/dessant/buster/wiki/Inaccessible-reCAPTCHA-audio-challenge Motivation reCAPTCHA challenges remain a considerable burden on the web, delaying and often blocking our access to services and information depending on our physical and cognitive abilities, our social and cultural background, and the devices or networks we connect from. The difficulty of CAPTCHA challenges can be so out of balance, that sometimes they seem friendlier to bots than they are to humans. The goal of this project is to improve our user experience on the web, by giving us easy access to solutions utilized by automated systems. The extension is also available for Chrome and Firefox: https://github.com/dessant/buster#readme The developer does not collect any personal data from this extension, visit the extension's privacy policy for more information. Reviews are not monitored for bug reports, please use GitHub for issues and feature requests. https://github.com/dessant/buster
