I’m Shahab Khan, the developer behind TechnoHelps. I built the Semantic Engine because I was tired of two things: expensive enterprise analytics suites and "black box" algorithms where you have no idea how your content is actually being graded. As a developer, I need to know the math behind the metrics—not just a generic score. I wanted to build something that was high-performance, completely transparent, and free for the community. You can hit our live API endpoint or pull the source code from GitHub to host it on your own infrastructure. This is day one for this project, and I’m looking forward to your technical feedback. What metrics would you like to see us add next? Let me know below!
