AI workout planner that builds your whole training week around your gear and goals
Tell it your goal, level, equipment and available days, and the AI trainer builds a full week of training including exercises, sets, reps and minutes.
A very deep database of movements, each with instructions and a demo animation, covering barbell, dumbbell, cable, machine, calisthenics and mobility work.
Hundreds of ready programs across weight loss, home, strength, HIIT, calisthenics, core, glutes and legs, plus structured splits like full-body, upper/lower and push-pull-legs.
Follow each session, track what you complete, and let the plan adapt as your strength and consistency improve.

A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
