DocTree

DocTree helps developers, independent learners, and researchers understand topics through structured learning articles tailored to their knowledge level and available reading time. Start with a topic or your own source material, then explore explanations with citations and diagrams. While reading, select a passage to ask the AI companion for a simpler explanation, an example, or a follow-up answer in context. Saved reading progress makes it easy to return and continue where you left off. DocTree also provides summaries and learning paths. A free plan is available, with optional paid plans for higher usage.
