DeepTutor is an agent-native personalized learning assistant from HKUDS (Hong Kong University Data Science Lab). Unlike most "AI tutor" products that are just chatbots with educational prompts, DeepTutor was architecturally designed from the ground up for multi-step learning sessions. It offers five integrated modes: Chat (conversation), Deep Solve (step-by-step problem solving), Quiz (adaptive assessment), Deep Research (literature-style investigation), and Math Animator (visual math explanations). Version 1.0.1 shipped April 10. The persistent cross-session memory is the technical differentiator. DeepTutor tracks what you've studied, what you've struggled with, and what you've mastered across sessions, using that context to adapt its approach. This is closer to how a human tutor operates — building a mental model of the student — than the stateless Q&A loop most AI tutors offer. DeepTutor supports OpenAI, Anthropic (Claude), and DeepSeek backends, making it backend-agnostic for institutions with existing API relationships. The Math Animator mode generates step-by-step visual breakdowns of mathematical problems, which addresses one of the weakest spots in current text-based LLM math tutoring. With 1,424 stars gained in a single day and 16.1k total stars, this is clearly meeting a real demand in the education space.

Ithihasas (Sanskrit for "thus it was") is a web app for exploring characters, relationships, and narrative arcs across the Ramayana and Mahabharata. Built in a few hours as a Show HN project, it lets you browse the cast of these 100,000-plus-verse epics, understand how characters are connected, and follow story threads without reading the full texts. The app uses an AI layer to surface contextual information—relationships between characters, their roles in key episodes, family trees—in a digestible format. It's aimed at people who grew up with these stories culturally but find the full texts overwhelming, as well as researchers and curious outsiders wanting entry points. The project is a solo indie build with no monetization yet. At 126 HN points on launch day, it found a real audience. The comments included Sanskrit scholars praising the character mapping, parents looking for ways to share the stories with children, and diaspora users noting the gap it fills between formal academic resources and casual pop-culture summaries. Small project, real need.
Reviewer scorecard
“Cross-session persistent memory is the missing piece in AI tutoring. Every other tool resets to zero each session. The five-mode architecture also makes sense — different learning tasks need different interaction patterns, not a one-size chatbot. Strong technical foundation from a credible academic lab.”
“Solid execution for a solo overnight build. The relationship graph and character cards are genuinely useful for navigating texts with hundreds of named characters. Would love to see this extended to the Puranas and eventually the full Vedic corpus—the underlying approach scales well.”
“Academic lab projects often look impressive on GitHub but stall after the paper is published. Support burden for open-source educational tools is brutal — student use patterns are unpredictable and error-prone. The Math Animator mode sounds great but math visualization AI is notoriously unreliable for complex topics.”
“The Mahabharata and Ramayana have dozens of regional variants with meaningfully different characters and events. An AI layer that doesn't distinguish between Valmiki's Ramayana, Tulsidas's Ramcharitmanas, and folk traditions will produce confident-sounding but regionally misleading information. The sourcing needs to be much more explicit.”
“Personalized education at scale is one of AI's most transformative applications. Cross-session memory is the first step toward a true AI tutor that knows your learning style, pace, and gaps. DeepTutor is early, but the architecture is the right one for where this is going.”
“AI as a gateway to pre-digital textual traditions is underexplored. The world's oldest continuous literary traditions—Sanskrit, Pali, Classical Arabic, Classical Chinese—are locked behind language and density barriers. Projects like this are the first step toward making those traditions genuinely accessible to billions of people whose cultural heritage they are.”
“For self-learners trying to pick up complex topics — design systems, coding, statistics — a tutor that remembers where you left off and adapts the difficulty is a game-changer. The quiz and deep-solve modes in particular map well to how creative professionals actually want to learn new technical skills.”
“The visual design is clean and respectful of the material—not the lurid illustrated pop-retelling aesthetic that dominates. For content creators working in mythology, historical fiction, or South Asian themes, this is a fantastic reference tool. The character relationship layer alone makes it worth bookmarking.”
