How To Build An AI App That Counts Calories From Pictures With Bolt and ChatGPT

As you may know, lately we’ve created a lot of tutorials on how to build with AI or applications that use AI or both. If you didn’t know, well, we’ve already created apps with Bolt , Replit Agent , Supabase , MCP Servers , Chatbots , and more. You can find them here (and filter for the keyword or tool you want to read about). But one thing we haven’t done so far, is show you how to incorporate AI in more complicated features, like media handling (images, voice, etc).
