ContextOS vs Obsidian

Obsidian gives you total freedom over how you organize notes, with plugins for nearly everything, including project logs. ContextOS trades that freedom for a fixed structure — sessions, decisions, ideas, next step — built around one job: getting you back into a project fast.

Where Obsidian wins

• Local-first files you fully own
• Huge plugin ecosystem and graph view
• Great for permanent, cross-referenced knowledge

Where ContextOS wins

• Purpose-built structure, no setup or plugin-hunting required
• AI-generated resume brief instead of manually re-reading notes
• Designed around resuming, not just note-taking

The honest take

If you already have an Obsidian vault with a working project-log template, ContextOS may feel redundant. If you've tried to build that system in Obsidian and it decayed after a few weeks, ContextOS removes the setup burden entirely.
