OpenMemory Self-Hosted — Chrome Extension

Fork of mem0ai/mem0-chrome-extension, customized for self-hosted Mem0 instances.

What's Different

This is a self-hosted version — no Mem0 Cloud, no Google login required. All data stays on your own infrastructure.

Key Changes from Upstream

Feature Upstream This Fork
Backend Mem0 Cloud (api.mem0.ai) Self-hosted Mem0 API (configurable URL)
Auth Google OAuth None needed (self-hosted)
Default endpoint https://api.mem0.ai https://mm.lalayunssl.xyz
Extension popup Popup with connect form ❌ Removed — click icon opens Sidebar directly
Memory Style N/A Formats <relevant-memories> blocks in OpenClaw Webchat with collapsible sections
Sidebar Basic memory list Full sidebar with memories, delete, settings, and Memory Style toggle
Platforms ChatGPT, Claude, Gemini, etc. All upstream + OpenClaw Webchat (bot.lalayunssl.xyz)

Memory Formatter (memory-formatter.ts)

Styles <relevant-memories> blocks injected by the openclaw-mem0 plugin:

  • Purple border card with 🧠 Recalled Memories badge
  • Collapsible sections: Long-term / Session — click to expand/collapse
  • Smart validation: Only styles real memory injections, ignores code discussions
  • Lit-compatible: Works with OpenClaw's closed Shadow DOM (scans light DOM .chat-text)
  • Toggle on/off in Sidebar → Settings → 记忆样式

Troubleshooting

Memory Style not working? - Ensure 记忆样式 is enabled in Sidebar → Settings - Check DevTools Console for [mem0-formatter] logs - The formatter needs <relevant-memories> text to start with "The following memories may be relevant"

Sidebar shows "Error loading memories"? - Verify your Mem0 API is running and accessible - Check the API URL in Settings - Try disabling then re-enabling the extension

中文说明

基于 mem0ai/mem0-chrome-extension 的二次开发版本，专为自建 Mem0 定制。

与上游的区别

功能 上游 本 Fork
后端 Mem0 云服务 (api.mem0.ai) 自建 Mem0 API（可配置 URL）
登录 Google OAuth 无需登录
默认端点 https://api.mem0.ai https://mm.lalayunssl.xyz
点击图标 弹出 Popup ❌ 已移除 — 直接打开 Sidebar
记忆样式 无 格式化 OpenClaw Webchat 中的 <relevant-memories> 为可折叠卡片
侧边栏 基础记忆列表 完整侧边栏：记忆列表、删除、设置、记忆样式开关
平台支持 ChatGPT、Claude、Gemini 等 全部上游平台 + OpenClaw Webchat

记忆样式功能 (memory-formatter.ts)

对 openclaw-mem0 插件注入的 <relevant-memories> 块进行样式美化：

  • 🟣 紫色边框卡片 + 🧠 Recalled Memories 标签
  • 可折叠分组：Long-term / Session — 点击展开/收起
  • 智能验证：只对插件注入的真实记忆生效，忽略代码讨论中提到的标签
  • Lit 兼容：适配 OpenClaw 的 closed Shadow DOM（扫描 light DOM .chat-text）
  • 在 Sidebar → Settings → 记忆样式 开关控制
