EverOS is a Python library and local-first memory runtime for agents and makers. It gives one portable memory layer across coding assistants, apps, devices, and workflows from day one. It stores conversations, files, and agent trajectories as readable Markdown, then syncs local SQLite and LanceDB indexes for fast retrieval and self-evolving reuse.
| Title | EverOS | Other Agent Memory Libraries |
|---|---|---|
| Markdown source of truth | ✅ Canonical .md files that are readable, editable, diffable, and Git-versioned |
❌ Usually API, vector, graph, dashboard, or database state |
| Direct file editing | ✅ Edit .md files; cascade watcher syncs |
❌ Usually SDK, API, dashboard, or backend update paths |
| Local three-part stack | ✅ Markdown + SQLite + LanceDB; no MongoDB, Elasticsearch, or Redis required | ❌ Often depends on managed services, vector DBs, graph DBs, or server stacks |
| User + agent tracks | ✅ User episodes/profile and agent cases/skills are separate first-class surfaces |
❌ Usually centered on chat history, profiles, entities, facts, or retrieval records |
| Orthogonal retrieval | ✅ Search by user_id, agent_id, app_id, project_id, and session_id |
❌ Usually app, namespace, tenant, thread, or graph scoped |
| Knowledge Wiki | ✅ Editable, source-backed Markdown knowledge pages with taxonomy, CRUD APIs, and topic search | ❌ Usually separate from memory, trapped in a dashboard, or not tied back to source files |
| Reflection | ✅ Offline memory evolution that merges episode clusters and refines profiles and skills between sessions | ❌ Usually retrieval-only memory with little background consolidation or long-horizon improvement |
EverOS adds durable memory to the agent and workflow platforms below—and comes built into Raven. Choose an integration to open its setup guide.

One OpenRouter API key is enough to start EverOS, write durable memories, and retrieve them with keyword search.
- Python 3.12+
- One OpenRouter API key
uv pip install everos
# or: pip install everosNo API key or server setup required—run one command to quickly experience how EverOS stores and recalls memory:
# If you installed EverOS as a package:
everos demo
# If you cloned or forked this repository and have not activated .venv:
uv run everos demoEnter something EverOS should remember, then ask a related question to watch the memory move through ingest -> extract -> index -> recall.

everos initThis creates ~/.everos/everos.toml and ~/.everos/ome.toml. Open
~/.everos/everos.toml; the generated model and OpenRouter URL are already
correct, so replace only the empty api_key:
[llm]
model = "openai/gpt-4.1-mini"
api_key = "<OPENROUTER_API_KEY>"
base_url = "https://openrouter.ai/api/v1"This is the smallest Tier 1 setup: memory add, flush, Markdown persistence, cascade indexing, and keyword search.
Use everos init --root <path> if you want a different memory root. Pass the
same --root <path> to subsequent commands.
everos server startKeep the server running, then open a second terminal and check it:
curl http://127.0.0.1:8000/healthLook for "status":"ok". With this one-key setup, capabilities.embed and
capabilities.rerank remain false until you configure them.
Note
Business endpoints live under /api/v2. The older /api/v1 prefix still
resolves to the same handlers so existing integrations keep working, but it
is a legacy alias that may be removed in a future major release — write new
code against /api/v2.
Add a tiny conversation:
TS=$(($(date +%s)*1000))
curl -X POST http://127.0.0.1:8000/api/v2/memory/add \
-H 'Content-Type: application/json' \
-d "{
\"session_id\": \"demo-001\",
\"app_id\": \"default\",
\"project_id\": \"default\",
\"messages\": [
{\"sender_id\": \"alice\", \"role\": \"user\", \"timestamp\": $TS, \"content\": \"I love climbing in Yosemite every spring.\"},
{\"sender_id\": \"alice\", \"role\": \"user\", \"timestamp\": $((TS+10000)), \"content\": \"My favorite coffee shop is Blue Bottle in SOMA.\"}
]
}"Flush the memory at the end of the session:
curl -X POST http://127.0.0.1:8000/api/v2/memory/flush \
-H 'Content-Type: application/json' \
-d '{"session_id":"demo-001","app_id":"default","project_id":"default"}'Search it back:
curl -X POST http://127.0.0.1:8000/api/v2/memory/search \
-H 'Content-Type: application/json' \
-d '{
"user_id": "alice",
"app_id": "default",
"project_id": "default",
"query": "Where do I like to climb?",
"method": "keyword",
"top_k": 5
}'You should see the Yosemite memory in the response. Keep
"method": "keyword" in this one-key setup because the API defaults to hybrid
search, which requires an embedding provider.
Tip
First memory unlocked.
You just gave EverOS a fact, flushed it into durable Markdown-backed memory,
and searched it back through the local index. That is the core loop.
Want to see the source of truth? Open ~/.everos and inspect the generated
Markdown files.
For annotated responses and the Markdown files EverOS creates, see QUICKSTART.md.
The OpenRouter one-key setup is EverOS Tier 1. It supports server startup, memory add and flush, durable Markdown storage, cascade indexing, and keyword search. Add optional providers only when you need the features below:
| Configuration | Adds |
|---|---|
[llm] only |
Core memory flow and keyword search |
Add [embedding] |
Vector/user hybrid search, reflection, and skill extraction |
Add [rerank] too |
Agentic search, default agent hybrid search, and Knowledge Wiki |
Add [multimodal] and parser extra |
Image, PDF, audio, and office-file ingestion |
Missing optional capabilities are reported by /health and return a clear
HTTP 422 if you request a feature that needs them.
Note
everos demo --live is different from the standalone demo in step 2: it
connects to a running server and uses the real add/flush/search flow. It uses
hybrid search, so add an embedding provider before you run it.
To ingest non-text content (image / pdf / audio / office documents)
through /api/v2/memory/add content items, install the optional
extra:
uv pip install 'everos[multimodal]' # or: pip install 'everos[multimodal]'This adds the parser's [svg] bundle for SVG support via cairosvg; the base
parser is already required by knowledge ingestion. Configure the [multimodal]
section in everos.toml; its default
model is google/gemini-3.8-flash via OpenRouter.
Office document support requires LibreOffice as a system dependency.
The parser shells out to soffice (LibreOffice's headless renderer) to
convert .doc / .docx / .ppt / .pptx / .xls / .xlsx to PDF
before feeding the result into the multimodal LLM. Without LibreOffice,
office uploads return HTTP 415 with a clear error message; PDF / image
/ audio / HTML / email parsing is unaffected.
Install on the host before serving office documents:
brew install --cask libreoffice # macOS
sudo apt-get install -y libreoffice # Debian / Ubuntugit clone https://github.com/EverMind-AI/EverOS.git
cd EverOS
uv sync # creates ./.venv and installs deps
uv run everos demo --plain # try the local educational demo; no API keys needed
uv run everos init # add one OpenRouter key to ~/.everos/everos.toml
uv run everos --help
make testNow that you have had your first successful EverOS moment, explore what people are building with persistent memory across agents, apps, and community integrations.
Use cases show what persistent memory makes possible in real products and workflows. Some examples are packaged in this repository; others point to external demos or integrations you can study and adapt.
