notelog vs Obsidian
Obsidian is a local Markdown editor you organize yourself, extended with plugins. notelog is built around your AI: Claude or ChatGPT saves and finds notes for you, no folders to maintain.
| notelog | Obsidian | |
|---|---|---|
| Organizing | No folders; your AI titles and finds notes | Folders, links and tags you maintain |
| AI | Built in through MCP: Claude, ChatGPT, Claude Code, Codex | No built-in AI; community plugins |
| Saving from a chat | “Save this to notelog” | Copy and paste, or a plugin setup |
| Offline and local files | Not yet (open-source local version in development) | Yes |
| Price | Free now; Cloud planned at $6/mo | App free; Sync about $4–5/mo |
Choose Obsidian if
- you enjoy building your own system of links and folders
- you need full offline use and local files
- you want a huge plugin ecosystem
Choose notelog if
- most of your notes start in AI conversations
- you would rather ask than browse folders
- you want it working in Claude or ChatGPT in a minute
Using both
The upcoming open-source version keeps notes as plain Markdown, so an Obsidian vault and notelog can point at the same files.
