geode vs headroom
geode: Geode is a free Obsidian plugin designed for secure, remote synchronization of your vault across multiple devices, including iOS, using user-owned encrypted storage. It also provides an API and MCP server, enabling AI agents to access and interact with the vault, utilizing it as memory for note-taking and maintenance.; headroom: Headroom compresses everything your AI agent reads — tool outputs, logs, RAG chunks, files, and conversation history — before it reaches the LLM. It achieves the same answers with a fraction of the tokens.

Seamlessly synchronize an Obsidian vault across personal laptops, phones, and tablets.

When to choose:
- Long tool output, logs, JSON responses or RAG chunks are driving up cost or hurting answers.
- You want compression without code changes: run it as a local proxy, an MCP server, or by wrapping Claude Code, Codex or Cursor.
- Compression must run locally, with originals cached so the model can retrieve the full text.
When to skip:
- Your agent's problem is missing or outdated docs, not too much context: a docs server fits better.
- You cannot add a component that must keep running and may add latency.
- Your tasks cannot tolerate lossy compression: verify answer quality on your own work first.
