An Obsidian alternative built specifically for project memory
Obsidian's flexibility is the appeal and, for project memory specifically, also the problem: you have to design the daily-note template, the linking structure, and keep the discipline going yourself. ContextOS skips the design phase entirely — the structure (sessions, decisions, ideas, next step) is fixed from day one, and the resume brief is generated for you rather than requiring you to re-read your own notes.
Who this is for
Best if you've tried a project-log setup in Obsidian and it fell apart after the initial motivation wore off.
Which should you use?
Use Obsidian if you want a local-first personal knowledge graph of linked markdown notes.
Use ContextOS if you want structured per-project memory with an AI resume briefing and zero folder upkeep.
Most builders don't switch — they keep Obsidian for its core job and add ContextOS as the project-memory layer: session history, a decision log with reasons, a resource vault, and an AI resume briefing when they return after time away.
