Description

Category: 3rd Party Integrations

The Hydrate plugin turns your vault into an AI-driven thinking companion that helps you work with ideas more fluidly. It lets you chat with your notes, explore relationships between concepts, and run meaning-based searches that go beyond simple keywords. You can generate outlines, summaries, and new content directly from existing material, making it useful for writing, research, and knowledge exploration. The plugin relies on remote AI services for most of its capabilities, and full functionality requires an account and a paid subscription. It also collects anonymous usage analytics and uses proprietary server-side components.

🔍 Setting Up Semantic Search with LM Studio

Hydrate supports semantic search using local embeddings via LM Studio. This lets you search your vault by meaning, not just keywords.

Setup Steps

  1. Install LM Studio from lmstudio.ai
  2. Download an embedding model - search for nomic-embed-text in LM Studio and download it
  3. Start the local server in LM Studio (Developer tab → Start Server)
  4. Configure Hydrate:
    • Open Hydrate settings in Obsidian
    • Enable "Remote Embeddings"
    • Set the embedding URL to: http://localhost:1234/v1/embeddings
    • Set the model name to match your downloaded model (e.g., nomic-embed-text)
  5. Index your vault - use the "Reindex Vault" button in settings

Once indexed, Hydrate will suggest relevant notes during chat and you can search by meaning across your entire vault.


🧩 Troubleshooting

  • If Hydrate does not appear after installation, try restarting Obsidian
  • Ensure you have the latest version of Obsidian
  • For issues, open an issue on GitHub
