About this vault
Personal knowledge management (PKM) is the practice of capturing, organizing, and connecting information you encounter so it compounds into expertise over time. The PKM tool landscape in 2026 spans three broad categories: read-later apps (capture layer), note-taking tools (synthesis layer), and AI-native apps that attempt to collapse both. Read-later apps — historically Pocket, Instapaper, Omnivore, and Matter — have consolidated sharply: Pocket shut down July 2025, Omnivore was acquired by ElevenLabs and shuttered in late 2024, Matter shut down 2024. Active options include Readwise Reader, Instapaper, and Burn 451. Note-taking and synthesis tools — Obsidian, Logseq, Roam Research, Notion, Capacities, and Heptabase — remain healthy, each serving a different mental model. AI-native tools like Mem.ai and Notion AI aim to reduce manual organization but lack opinionated reading workflows. Burn 451 occupies a unique position: a read-later app with an expiration mechanic (24-hour burn, 30-day spark, permanent vault) that forces action rather than accumulation, plus an MCP server that exposes your reading vault to Claude and other AI agents. The emerging pattern for serious PKM practitioners is a two-layer stack: Burn 451 as the high-pressure inbox that filters what actually matters, and Obsidian or Logseq as the permanent synthesis layer where insights compound.
