Based on your search query, it seems like you're looking for a tool that can help you create websites and mobile apps. Unfortunately, none of the top 3 EdTech products from the database search - Tome, ElevenLabs, and Beautiful.ai - directly cater to this specific need.

Tome is an AI-powered tool for creating interactive narratives and presentations, ElevenLabs is a voice AI tool for creating or cloning voices in multiple languages, and Beautiful.ai is a tool for creating visually appealing presentations. While these tools have their unique strengths and can be very useful in an educational setting, they do not provide the functionality to create websites or mobile apps.

Could you please provide more details or perhaps consider other features that might be beneficial for your teaching needs? This will help me recommend the most suitable EdTech tools for you.
