Give Your AI Agent a Real Memory in One Command (Hermes v0.14 + Obsidian)

#ai #opensource #productivity #tutorial

Most AI agents have amnesia. You explain the same context every session. Here is a five-minute fix that turns any LLM into something with actual continuity.

The trick: use a markdown vault as memory

A vector database is the obvious choice and usually the wrong one. Embeddings give fuzzy recall and lock you into a specific provider. A plain Obsidian vault gives the agent exact, named, editable memory that the human can also read.

Hermes Agent v0.14 shipped May 16, 2026 with a first-class Obsidian provider. One command wires it up.

Install Hermes

Three paths, pick one:

pip install hermes-agent && hermes postinstall
Enter fullscreen mode Exit fullscreen mode 
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
Enter fullscreen mode Exit fullscreen mode 
irm https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.ps1 | iex
Enter fullscreen mode Exit fullscreen mode

Wire in Obsidian 

hermes memory setup --provider obsidian --path ~/vaults/work
hermes memory status
Enter fullscreen mode Exit fullscreen mode

That is the whole memory setup. The agent now reads and writes markdown files in that vault every session.

Optional power-ups

  • Obsidian Local REST API plugin on localhost:27123 gives programmatic R/W during agent execution, not just at boot.
  • Obsidian MCP server (cyanheads/obsidian-mcp-server) exposes the vault as Model Context Protocol tools — any MCP-aware client can use the same memory.
  • Omi captures passive screen and mic context into the vault, which turns the workflow into a true second brain.

What else landed in v0.14

  • 22 messaging platforms (Telegram, Discord, Slack, WhatsApp, Signal, Teams, LINE, more)
  • 400+ supported models (xAI Grok SuperGrok OAuth, Nous Portal, OpenRouter, Ollama)
  • 68 built-in agent tools
  • hermes proxy — OpenAI-compatible local endpoint for OAuth-only providers
  • /handoff — live session transfer between devices
  • 19s faster cold start, 180x faster browser CDP
  • MIT license, 100K+ stars (fastest project to 100K)

Why this matters for builders

If your agent stack is a glue script that pastes the same context into every prompt, you are paying tokens for amnesia. Move the context out of the prompt and into a vault, and prompts shrink while quality goes up. Long breakdowns and reference vaults live at cptdigital.com.
