Hello and welcome to KhanDevs. I am Khan Hassan Riaz, a visually impaired software developer with a degree in Special Education. I built this platform to share the software and tools I develop, with a primary focus on making education and technology accessible for everyone.
First, a massive thank you to everyone who has used and supported ProQuiz Simulator. Your trust and support are the main reasons this company and website exist today.
ProQuiz Simulator was our very first project, and its journey started with a simple goal: generate mock tests and practice MCQs. As development continued, it evolved into a complete learning academy where candidates prepare for PPSC, FPSC, and other Public Service Commission exams in a fully accessible way.
You can read complete details on the ProQuiz Simulator page. It is not just a basic app. It is a complete solution for modern learning challenges, and one of its greatest strengths is the quality of its educational content.
The impact of ProQuiz Simulator became the driving force for our future products. We have always been passionate about software development, and modern AI has made it easier to bring practical ideas to life. We are continuously building new tools that solve real problems.
This software is specially designed for visually impaired users. It helps detect spelling mistakes, suggests corrections, and allows quick replacement with the right words. It also supports fast voice typing and custom dictionaries. Active development is ongoing, and more features are coming soon.
Typing speed and accuracy are crucial. This tool offers an accessible way to practice and test WPM (Words Per Minute). Users can practice specific word sets or paste custom paragraphs. One standout accessibility feature solves a common challenge for visually impaired typists: quickly identifying the next word. Built-in text-to-speech reads the next word instantly during practice.
Along with these flagship tools, we always have a few smaller projects running in the background. If you have any suggestions, ideas, or a challenge that software could solve, please contact us.
