With 34,000+ GitHub stars and a v1.5 release driven by 36 merged community pull requests, DeepTutor from Hong Kong University's Data Science Lab delivers a full agent-native learning workspace that goes far beyond chatbot wrappers. Eight integrated surfaces — Chat, Deep Solve, Quiz Generation, Deep Research, Math Animator, Co-Writer, Book generation, and Mastery Practice — share a unified context so the objective follows the learner, not the tool. The platform's three-layer memory architecture (L1 working, L2 session, L3 long-term) makes personalization inspectable rather than opaque, letting users see exactly what the system remembers and why. Knowledge retrieval operates across five pluggable engines — LlamaIndex with FAISS vectors, PageIndex for page-level citations, GraphRAG for knowledge-graph traversal, LightRAG for local or server-offloaded retrieval, and linked Obsidian vaults — with document parsing via MinerU, Docling, markitdown, or PyMuPDF4LLM. Partners extend the tutoring brain to 15+ messaging platforms including Slack, Discord, Telegram, Matrix with E2EE, and Mattermost, each carrying private memory with branch, resume, and replay capabilities. Subagent integration brings Claude Code, Codex, Gemini, and Kimi directly into learning sessions. The system supports 30+ LLM providers from OpenAI and Anthropic to Ollama for fully local operation, with multi-user isolation, admin controls, and a full CLI interface. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

Scholarsome is a self-hosted flashcard platform where you create study sets, share them with other learners, and drill them through flashcards and automatically built quizzes. Start a set from scratch in the card editor, writing terms and definitions with rich formatting, images, and LaTeX expressions for math and science notation. Bring your existing material with you instead: decks import from Anki, Quizlet, and CSV files, and finished sets export back to the same formats so nothing is trapped inside. Share a set with classmates or keep it private with visibility controls, then let everyone study from the same central copy with no device syncing to manage. Multiple learning modes mimic real flashcards for relaxed review, while the quiz builder generates fill in the blank, true or false, and multiple choice questions from your cards for a stricter test. Teachers can assemble a class deck once and publish it to every student at the moment it is ready. Because the whole system runs on your own server, study data stays under your control rather than behind a subscription paywall.
