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.

AI data infrastructure for building production-grade models
One configurable annotation surface for image, video, text, and audio projects, so multimodal datasets can be labeled without switching tools.
Search, filter, and inspect datasets to find the examples that will most improve a model, then route them into targeted annotation or review queues.
Dashboards for annotation volume, reviewer agreement, and project progress, plus advanced analytics on upper tiers for program-level reporting.
Metered orchestration capacity for running annotation, evaluation, and data-processing workloads, scaled by plan from roughly 1K to 10K compute hours.
