Collaborative Knowledge Base on Local-First Markdown
C7/10May 12, 2026
WhatA team knowledge base that combines Obsidian-style local-first markdown files with real-time collaboration, permissions, and sharing features that non-technical users can adopt easily.
SignalMultiple users describe being stuck on Notion despite wanting to leave because no local-first tool supports team collaboration, permissions, and sharing well enough — they want the data ownership of Obsidian with the team usability of Notion.
Why NowLocal-first sync technology (CRDTs, Automerge, etc.) has matured enough to enable real-time collaboration on local files, and AI agent workflows increasingly benefit from plain-text knowledge bases that tools like Notion cannot easily expose.
MarketSmall-to-mid teams (2-50 people) currently paying for Notion, Confluence, or Coda who want data ownership; TAM overlaps with Notion's $10B+ market; key gap is that Obsidian explicitly does not target teams and Notion does not offer local-first.
MoatNetwork effects within teams create strong switching costs once a team's shared vault, templates, and workflows are established; CRDT-based sync engine is technically difficult to replicate well.
