📚 Student LLM Wiki — AI-compiled knowledge base for university students. Drop course slides, get a persistent interlinked wiki. Feynman review, exam prep, confidence decay, cross-course connections. Based on Karpathy's LLM Wiki pattern. Works with Claude Cowork / Claude Code / Claudian + Obsidian.学生大语言模型维基百科——专为大学生打造的AI编译知识库。

Open source local-first knowledge base maintained by an LLM agent. Implements Andrej Karpathy's LLM Wiki pattern.

Self-hosted MCP server + dashboard giving Claude Code, Cursor & Hermes agents shared long-term memory over a git-backed markdown vault. Agent-native, Obsidian-compatible second brain — markdown RAG, no vector DB.

A lightweight, instant-access scratchpad — from quick snippets to AI prompts, every piece of scattered text finds its place

Self-hosted persistent memory for AI agents. Markdown for humans, MCP for agents.

The easiest way to start a second brain — an Obsidian vault Claude Code sets up in minutes and maintains for you

Self-hosted Telegram personal assistant on Supabase. Bring your own LLM API key.

An AI-native KMS and next-gen RAG prototype. Enforces strict tree-shaped index constraints and compiler-like diagnostics after every write, enabling agents to self-heal knowledge structures and eliminate garbage-in, garbage-out RAG pain points.

A second brain you build by talking to Claude Code. Obsidian vault + plugin (ingest, query, lint) that turns books and articles into a cross-linked personal wiki.

Every video and paper assumes a body of a priori knowledge. Priori supplies the parts you're missing.看视频 / 读文章学习：选中即问 AI、大纲、双语字幕。走订阅 CLI，零 API 花费。

Turn a week of lecture material — slide decks and captions — into structured, source-anchored study notes with Claude. Build once to a cached JSON, then render cheaply to Markdown, Anki cards, or Notion pages. Every topic cites its timestamp and slide range.

Podcasts and videos you actually remember, and what they mean for you. A free, open-source Claude plugin (needs Pro or Max) that turns podcast and video links into Notion notes.

Open-source Claude Code assistant that turns your notes into a personal chief of staff: capture notes, track follow-ups and deadlines, get priority alerts, and ask your notes questions.

Copy citations with file links & line numbers for AI agents. Paste precise note references into any LLM chat.

File-native judgment practice for partner-coupled agents - propose then accept, thin load, your vault stays private

Give your AI a second brain. Altretta connects your local, encrypted knowledge vault to 70+ AI agents with query-first, cited retrieval and signed provenance.

A Model Context Protocol (MCP) server that implements the Zettelkasten knowledge management methodology, allowing you to create, link, explore and synthesize atomic notes through Claude and other MCP-compatible clients.
