Clew

Clew is a learning workspace that turns a subject into a graph of concepts and a path through it. The user names a topic, a paper, a field or a chapter, and Clew lays out the prerequisite chain from what the learner already knows to the target, with nodes holding ideas and edges holding dependency. An agent then runs a study loop along that path with quizzes, recall checks and gap finding, while the reading and thinking stay with the learner. It is built for self taught researchers, engineers learning a new stack, students working through a syllabus, and writers organizing scattered ideas. Clew can propose structure from an imported syllabus that the user accepts or rejects, skips concepts the learner already owns, flags weak spots and loops back to them, and tracks a confidence score on every node over time. Graphs are stored in Clew's own database, and any node or subgraph can be exported to Markdown for Obsidian, a git repository or any other tool, so the material is never locked in. Sign in is through a Google account. Clew is in public beta and is free to start. A Pro plan is announced, unlocking longer paths, the full learning loop agent, richer exports and priority access to new features, but it is not yet available: the site offers a waitlist and publishes no price.
