Chat and RAG inside the vault you already own: ask your notes, not the cloud wiki — Notion Agent's local cousin for people whose second brain is Markdown.

Overview

Obsidian Copilot is the agent that does not ask you to move the vault: chat the notes, retrieve the paragraph, keep files as files. Notion Agent lives in a workspace; this lives in Markdown.

Quality is the model you plug in. The plugin is another thing to maintain. If the second brain is already Obsidian, this is the AI that respects that. If it is Notion, skip it.

Pros / Cons

Pros

  • AI on the vault you already trust
  • BYO or local models, notes stay files
  • Open-source plugin, not a new wiki
  • Default when Obsidian is the second brain

Cons

  • Another plugin to keep updated
  • Quality is whatever model you wired
  • Useless if the notes are in Notion

Who it's for

01

Asking the vault instead of a cloud wiki

02

Local RAG over Markdown

03

Chat that never leaves the notes folder

04

Bottom line

RAG in the vault — buy the plugin if Obsidian is home, skip it if the wiki is Notion.
