EverOS

One memory, usable everywhere.

A portable memory layer: local-first, Markdown-native, one self-evolving memory shared across agent apps.

12,081 star v1.2.3 Memory / storage GitHub

Install

Python 3.12+; an OpenRouter API key. Known pitfalls: hybrid retrieval needs an embedding provider, so the one-click minimal configuration can only use "method": "keyword"; ingesting Office documents requires LibreOffice installed on the system; /api/v1 is a legacy alias and will be removed; endpoints return HTTP 422 when an optional capability is missing; since v1.2.3 a failed background loop SIGTERMs the process, so an external restart mechanism such as systemd/Docker/K8s is needed.

A Python package: install with pip or uv, then run the command it ships.

uv pip install everos # or: pip install everos

Multimodal, optional

uv pip install 'everos[multimodal]' # or: pip install 'everos[multimodal]'

Full tutorial

01Run everos demo first to see the demo (no API key needed)

02everos init generates ~/.everos/everos.toml and ~/.everos/ome.toml

03Put your OpenRouter API key into everos.toml

04everos server start launches the service; verify with curl http://127.0.0.1:8000/health

05Write, persist, and search memory through /api/v2/memory/add, /api/v2/memory/flush, and /api/v2/memory/search

config

# everos.toml [llm] model = "openai/gpt-4.1-mini" api_key = "<OPENROUTER_API_KEY>" base_url = "https://openrouter.ai/api/v1"

Features

·Markdown memory files versioned with Git, local SQLite + LanceDB indexes, no external database dependency

·Hybrid keyword + vector retrieval, with orthogonal multi-dimensional search across user/agent/app/project/session

·Self-evolving memory through cross-session reflection; optional multimodal ingestion (images/PDF/audio/documents); the ecosystem includes a Claude Code plugin, EverMem Sync and more

AI Agent 的记忆通常是黑盒——你不知道它记了什么、存在哪、能不能直接改——EverOS，10300 个 Star，把这件事做成了一堆你能打开的 .md 文件，本地跑，不依赖任何托管服务。一句话：给 AI Agent 装一个本地优先的持久记忆层，存的是 Markdown 文件，能读、能改、能 git diff，pip 一条命令装好。

An AI agent's memory is usually a black box — you don't know what it remembered, where it's stored, or whether you can edit it directly. EverOS, 10,300 stars, turns all of that into a pile of .md files you can open, running locally with no hosted service required. In one line: a local-first persistent memory layer for AI agents, stored as Markdown files you can read, edit, and git diff — installed with a single pip command.
