Writing & notes
What it does
A plugin that lets you discuss your notes with an assistant without copying anything out: it pulls in the relevant notes automatically, can write back into the vault, and now connects to ChatGPT or Claude accounts directly rather than requiring an API key. Requires Obsidian. The author states it is no longer under active development and that issues may not be answered promptly, with community forks available; note also that whatever it reads goes to the AI service you connect.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
