Notion is an all-in-one productivity workspace that blends flexible document editing with relational databases, wikis, and task management. It lets individuals and teams build customized operating systems, centralize documentation, and automate workflows using integrated AI tools and custom agents.
This framework outlines a concrete system for building an autonomous, LLM-maintained personal wiki in markdown using Obsidian as the interface. Rather than relying on complex RAG pipelines, an LLM incrementally processes raw source documents, generates cross-linked concept pages, answers complex research queries, and lints the wiki for gaps. It treats knowledge management like a compiled codebase where the model handles all the editing and structuring.
Are.na is a visual research and knowledge-building platform designed without ads or algorithmic feeds. Users collect images, links, notes, and PDFs into flexible, collaborative channels called 'blocks'. It offers a quiet, community-driven alternative to algorithmic moodboard and bookmarking platforms.
Ars Umbris is an open-source, local-first workspace and framework for structuring personal or company knowledge in plain files. It adds YAML-based typing and diagnostics to Markdown documents, providing an interactive graph and MCP-compatible harness for AI agents to navigate and update your notes.
A conceptual framework based on Andrej Karpathy's method for organizing research into a persistent, self-updating markdown knowledge base. Instead of relying on RAG or infinite context windows, an LLM compiles raw sources into structured markdown files, queries them, and files its own outputs back into the wiki. The user steers and inspects the knowledge base via an IDE like Obsidian while the model writes and maintains the index.
An architectural idea file by Andrej Karpathy proposing a persistent, compounding markdown wiki maintained by an LLM agent rather than transient RAG queries. Users feed raw documents into a repository while the AI organizes, cross-references, and updates topic pages viewed alongside an editor like Obsidian. Designed as a prompt spec, it is intended to be handed to a coding agent to build a customized local setup.
YapThread imports your saved Twitter/X bookmarks via a browser extension and organizes them into a searchable library. An AI assistant queries your saved content to answer questions, cite original tweets, and surface specific quotes so your bookmarks do not get lost.
