Overview
ManySpace is a study system for independent learners of mathematics, physics and AI. It maps the three subjects as a single prerequisite graph: every topic page names what to learn before it and what it opens next, and learners follow a goal route from foundations to more advanced material.
Study happens through captioned lesson films with checks, plus deeper interactive lessons or generated practice on some topics. A review queue and progress tracking bring the learner back to material that needs revisiting. The site also offers 18 interactive tools, including a derivative visualizer, probability lab, gradient descent playground and attention visualizer.
A free account opens the first three lessons of each subject, with no payment details required; topic pages, subject maps and the tools are available without an account. The full workspace costs $19.99 per month and adds every topic's lesson film, the goal route, review queue and progress together, and offline access to previously loaded pages.
ManySpace states that lesson films were made with AI assistance and that not all have been reviewed end to end by a subject expert. Paid access does not remove prerequisite locks, and no live tutoring or qualification is included.
