OpenCode Memory

A persistent memory system for AI coding agents that enables long-term context retention across sessions using local vector database technology.

Visual Overview

Core Features

Local vector database with SQLite, persistent project memories, automatic user profile learning, unified memory-prompt timeline, full-featured web UI, intelligent prompt-based memory extraction, multi-provider AI support (OpenAI, Anthropic), 12+ local embedding models, smart deduplication, and built-in privacy protection.

Getting Started

Add to your OpenCode configuration at ~/.config/opencode/opencode.json:

{
  "plugins": ["opencode-mem"]
}

The plugin downloads automatically on next startup. macOS users with Apple Silicon must install Homebrew SQLite and configure the custom path - see our Wiki for details.

Usage Examples

memory({ mode: "add", content: "Project uses microservices architecture" })
memory({ mode: "search", query: "architecture decisions" })
memory({ mode: "profile" })
memory({ mode: "list", limit: 10 })

Access the web interface at http://127.0.0.1:4747 for visual memory browsing and management.

Configuration Essentials

Configure at ~/.config/opencode/opencode-mem.jsonc:

{
  "storagePath": "~/.opencode-mem/data",
  "embeddingModel": "Xenova/nomic-embed-text-v1",
  "webServerEnabled": true,
  "webServerPort": 4747,
  "autoCaptureEnabled": true,
  "memoryProvider": "openai-chat",
  "memoryModel": "gpt-4",
  "userProfileAnalysisInterval": 10,
  "maxMemories": 10
}

Full documentation available in our Configuration Guide.

Important: v2.3 Breaking Changes

User-scoped memories removed. All memories now project-scoped. Update configuration:

// OLD: Remove these
{
  "userMemoryAnalysisInterval": 10,
  "maxProjectMemories": 10
}

// NEW: Use only
{
  "userProfileAnalysisInterval": 10,
  "maxMemories": 10
}

Remove scope parameter from all memory() calls. See Migration Guide for details.
