what AI can build

Local Markdown vault with wikilinks, search, and a simple graph view.

Markdown notes + links are easy; the plugin ecosystem and Sync/Publish habits are the product.

questions

Can AI replace Obsidian?

Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: community plugins, Obsidian Sync. Validate the prompt against your own acceptance criteria before committing.

How much does Obsidian cost?

Obsidian is listed at about $4/month (Catalyst / Sync (approx), checked 2026-08-05), or $48 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing Obsidian?

Honestly: community plugins; Obsidian Sync; mobile apps; Publish. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Obsidian?

No mature open-source alternative is listed yet. The prompt is an unverified starting point, not proof that a one-shot replacement will work.
