Side-by-Side Comparison
Objective metrics, no spin.
Slack-first SMBs that want a knowledge base answering repeat questions without asking everyone to learn a new app.

Privacy-conscious individuals, researchers, and engineers who want durable plain-text notes with flexibility to build a custom system.
Teams needing real-time collaboration or shared wikis — Obsidian is fundamentally single-user and file-based.
