Question: I'm looking for a platform that offers flexible learning options, such as adjustable content length and format.

If you need a platform that can accommodate different learning styles, Coglayer is a good option. It can create custom, in-depth text and audio content based on your specific learning needs. You can control the length of the output (5-30 minutes) and consume the content in different ways, such as reading, listening, downloading and sharing. Coglayer also can generate audio, turning text into an audio file you can listen to, and it can be used for learning in a variety of subjects.

Another option is Shiken, a microlearning platform that uses AI to accelerate learning. Shiken has a range of tools, including AI-generated content, microlearning, scenario-based learning and game-based learning. It has flexible pricing, including a free tier, and can be integrated with more than 4,000 apps through Zapier, so you can easily fit it into your existing workflow. Shiken also has a mobile app so you can learn on the go, too.

If you're looking for a teacher-focused tool, To Teach can create AI-generated learning materials and exercises based on students' interests. It's got tools like an AI Lesson Planner, reading and listening comprehensions, and multiple language levels. With customizable content and a range of pricing tiers, including a free option, To Teach makes lesson planning easier and learning more effective.

Last, Quenti offers a modern learning experience with different study modes like flashcards, games and practice tests. Its AI features, including smarter multiple-choice questions and written response grading, can help you learn more efficiently. The platform also offers unlimited studying and set creation on a free plan, so students can use it, but more advanced plans for teachers and organizations offer more.
