Hello there! Based on your needs, I would recommend Questionwell AI. This platform uses artificial intelligence to generate questions based on provided material, which aligns well with your requirement for quick and efficient question generation.

The key feature that stands out is the Question Generator. This allows you to generate questions based on various inputs, including text, images, audio, or video. You can choose the topic, language, and question type (multiple choice, fill-in-the-blank, or short answer), providing a wide range of flexibility in creating your questions.

Another useful feature is the Export function. This allows you to export the questions to various platforms such as Canvas, Quizziz, Quizlet, Kahoot, Blooket, Gimkit, Moodle, or Doc. While it doesn't explicitly mention Google Forms, you can export the questions as a PDF and then easily copy them into a Google Form.

Questionwell AI also offers a user-friendly interface and the convenience of signing in using a Google account. It has different pricing plans, including a free Basic plan, which allows you to create up to 10 monthly questions. If you need to create more questions, the Pro and Premium plans offer higher limits and additional features.

In summary, Questionwell AI seems to be a robust tool that can help you create diverse question sets quickly and efficiently, and potentially integrate with Google Forms through its PDF export feature.
