Fitly AI is an AI agent that runs your whole fitness life through one conversation. Type, talk, or send a photo and it logs meals, workouts, water, and weight. Name a destination (down 20 by the wedding, a first 10K) and it writes the game plan: your meals, your training, your pace to arrival. When life throws a curveball, the plan bends, not you. It is also an open platform: an MCP server with 50+ tools lets Claude, ChatGPT, or any agent you already use read your progress and log for you.
