Give your team a single, shared cloud workspace. Knowledge isn't confined to one person — anything a teammate writes is immediately available to everyone else and to their AI assistants. Edit a note together in real time, hand work off between humans and agents, and build one connected knowledge base instead of scattered copies. Same pricing - start with one user and add more as needed.

Pick up right where you left off — in Claude, Codex, Cursor, ChatGPT, or anything that speaks MCP. Your knowledge lives as Markdown files that both you and your AI can read, write, and search.

• Local-first. Plain text on your disk. Forever.
• Two-way. AI and humans write to the same files; sync keeps them in step.
• A real knowledge graph. Observations and wikilinks compound into context.
• Semantic search. Find notes by meaning, not just keywords, with optional cross-encoder reranking for higher-quality vector and hybrid results.
• MCP-native. Works with every major AI client and IDE.
• Progressive tool discovery. Every tool is tagged with behavior hints (read-only, destructive, idempotent) so agents pick the right tool on demand — no wasted context trying things to see what they do.
• Cloud, optional. Sync across devices when you want — never required.

Pick the path that fits you. Both run the same product on the same Markdown.

Basic Memory changed my whole relationship with LLMs. I switched from GPT and Gemini to exclusively Claude and Claude Code because of this integration and am completely revamping all our company's processes around a Basic Memory workflow.

— Alex, TrainerDay

Basic Memory is the missing 'wow' factor in AI chatbots. Now I can't imagine Claude or Claude Code without it.

— Caleb, Caleb Picker Consulting

I don't code without Basic Memory anymore. It's such a time saver to be able to refer to projects I don't currently have active and keep a running log of all my learnings and ProTips.

— @groksrc, Developer

This repository is also the canonical home for Basic Memory's host-native agent packages. The core Python package, Claude Code plugin, shared skills, Hermes plugin, and OpenClaw plugin all ship from the same source tree.

Maintainers can verify the whole consolidated surface from the repo root:

just package-check

Package-local justfiles are also available when working inside one host:

just package-check-claude-code
just package-check-skills
just package-check-hermes
just package-check-openclaw

The Claude Code plugin is the bridge between Claude's working memory and Basic Memory — session-start briefings, pre-compaction checkpoints, an opt-in capture output style, and /basic-memory:bm-setup · :remember · :share · :status.

Connect the Basic Memory MCP server first — see Connect your AI client. The plugin's hooks and skills call it, so it's a hard prerequisite. Then add the marketplace and install:

claude plugin marketplace add basicmachines-co/basic-memory \
  --sparse .claude-plugin plugins/claude-code
claude plugin install basic-memory@basicmachines-co

Source: plugins/claude-code.

Framework-agnostic SKILL.md files live in skills/. If your Skills CLI supports repository subdirectory sources:

npx skills add basicmachines-co/basic-memory/skills

If your installed Skills CLI cannot load that source, update the CLI or copy the memory-* directories from skills/ into your agent's skills directory.

Hermes keeps its native plugin shape under integrations/hermes:

Managed installation requires a Hermes Agent release containing the manifest-v2 installer fix. Hermes Agent v0.20.5 (v2026.8.19) and earlier are not supported. If the installer says it only supports manifest_version: 1, update Hermes to a release containing that fix.

hermes plugins install basicmachines-co/basic-memory/integrations/hermes

OpenClaw stays package-native and publishes from integrations/openclaw:

openclaw plugins install @basicmemory/openclaw-basic-memory

If you went the Cloud route, the web app walks you through client connect. The snippets below are for local installs.

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "basic-memory": {
      "command": "uvx",
      "args": ["basic-memory", "mcp"]
    }
  }
}

Restart Claude Desktop. Notes live in ~/basic-memory by default.

claude mcp add basic-memory -- uvx basic-memory mcp

For the full memory bridge — session briefings, pre-compaction checkpoints, and the /basic-memory:* commands — also install the Claude Code plugin on top of this.

Add to ~/.codex/config.toml:

[mcp_servers.basic-memory]
command = "uvx"
args = ["basic-memory", "mcp"]

Codex can keep its default MCP approval behavior, or you can pre-approve eligible Basic Memory tools by adding this server-scoped setting to the same table:

[mcp_servers.basic-memory]
command = "uvx"
args = ["basic-memory", "mcp"]
default_tools_approval_mode = "approve"

This does not disable Codex approvals globally or expand which Basic Memory projects the server can access. Codex still requires approval for tools that advertise a destructive annotation, including Basic Memory's writes, edits, and deletes. If you installed the Basic Memory Codex plugin, use its plugin-scoped configuration instead.

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "basic-memory": {
      "command": "uvx",
      "args": ["basic-memory", "mcp"]
    }
  }
}

Add to your User Settings (JSON):

{
  "mcp": {
    "servers": {
      "basic-memory": {
        "command": "uvx",
        "args": ["basic-memory", "mcp"]
      }
    }
  }
}

Basic Memory exposes OpenAI-compatible search and fetch tools for Custom GPT actions. See the ChatGPT integration guide.

No setup. Point Obsidian at ~/basic-memory (or your project folder) and the same wikilinks, frontmatter, and Markdown your AI writes appear in your graph view. Edit either side — sync handles the rest.

Try a prompt:

"Create a note about our project architecture decisions."
"Find information about JWT auth in my notes."
"What have I been working on this week?"

• Automatic updates. Basic Memory keeps itself up to date for uv tool and Homebrew installs; bm update triggers a manual check.
• Semantic vector search. Find notes by meaning, not just keywords. Hybrid full-text + vector ranking with FastEmbed embeddings, on SQLite or Postgres.
• Optional search reranking. Rescore the strongest vector and hybrid candidates with a local FastEmbed cross-encoder or a LiteLLM-backed provider.
• Schema system. Infer, validate, and diff the structure of your knowledge base with schema_infer, schema_validate, schema_diff.
• Per-project cloud routing. Route individual projects through the cloud while others stay local, via API key (bm project set-cloud).
• Smarter editing. edit_note append/prepend auto-creates notes when missing; write_note guards against accidental overwrites.
• Richer search results. Matched chunk text is included so the LLM gets context, not just hits.
• FastMCP 3.0 + tool annotations. Every tool ships with MCP behavior hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) so agents can discover capabilities progressively at runtime instead of guessing or burning tokens.
• CLI overhaul. --json output for scripting, workspace-aware commands, and an htop-inspired project dashboard.

Full CHANGELOG for v0.18 → v0.20.

Reranking adds a second relevance pass after vector or hybrid retrieval. It is disabled by default because it adds inference latency and, for the local provider, a first-run model download. Text, title, and permalink searches keep their existing ranking.

Enable the default local FastEmbed reranker:

export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
export BASIC_MEMORY_RERANKER_ENABLED=true

The default model is jinaai/jina-reranker-v1-tiny-en. To use a hosted reranker through LiteLLM instead:

export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
export BASIC_MEMORY_RERANKER_ENABLED=true
export BASIC_MEMORY_RERANKER_PROVIDER=litellm
export BASIC_MEMORY_RERANKER_MODEL=cohere/rerank-v3.5
export COHERE_API_KEY=...

The feature fails fast on invalid configuration and does not silently fall back to retrieval order when an enabled provider fails. See the semantic search guide for provider setup, all settings, tuning, pagination, and failure behavior.

Most LLM conversations are ephemeral. You ask a question, get an answer, then everything is forgotten. Workarounds have limits:

• Chat history captures conversations but isn't structured knowledge.
• RAG lets the LLM query your documents but not write back to them.
• Vector DBs need complex infra and usually live in someone else's cloud.
• Knowledge graphs need specialized tooling to maintain.

Basic Memory takes a simpler path: structured Markdown files that humans and LLMs both read and write.

• All knowledge stays in plain files you control.
• Both sides read and write to the same files.
• Familiar Markdown with semantic patterns — no new format to learn.
• A traversable graph the LLM can follow link by link.
• Works with the editors you already use (Obsidian, VS Code, anything).
• Just files plus a local SQLite index. No servers required.

You're chatting normally about coffee:

I've been experimenting with brewing methods. Pour over gives more clarity than French press, water at 205°F seems best, and freshly ground beans make a huge difference.

Ask the LLM to capture it:

"Make a note on coffee brewing methods."

A Markdown file appears in your project directory in real time:

---
title: Coffee Brewing Methods
permalink: coffee-brewing-methods
tags: [coffee, brewing]
---

# Coffee Brewing Methods

## Observations
- [method] Pour over highlights subtle flavors over body
- [technique] Water at 205°F (96°C) extracts optimal compounds
- [principle] Freshly ground beans preserve aromatics

## Relations
- relates_to [[Coffee Bean Origins]]
- requires [[Proper Grinding Technique]]
- affects [[Flavor Extraction]]

Next session, the LLM picks up the thread. It follows the relations to surface what you already know about Ethiopian beans and burr grinders, and builds on it instead of starting over. You see the same files in Obsidian or your editor. Edit them by hand — the AI sees your changes too.

Real two-way flow: humans edit Markdown, LLMs read/write through MCP, sync keeps everything consistent, and the source of truth is always your files.

Each file is an Entity. Entities have Observations (facts about them) and Relations (links to other entities). That's the whole grammar.

---
title: <Entity title>
type: note
permalink: <uri-slug>
tags: [optional, list]
---

Facts about the entity. Categories in [brackets], tags with #, optional context in parens.

- [method] Pour over highlights subtle flavors
- [tip] Grind medium-fine for V60 #brewing
- [fact] Lighter roasts contain more caffeine than dark
- [resource] James Hoffmann's V60 technique on YouTube
- [question] How does temperature affect compound extraction?

Wiki-style links that form the graph. Single-token relation types, or quote multi-word ones.

- pairs_well_with [[Chocolate Desserts]]
- grown_in [[Ethiopia]]
- requires [[Burr Grinder]]
- "pairs well with" [[Dark Chocolate]]

Bare - [[Target]] and prose - Worth checking out [[Target]] index as links_to. Full reference in the docs.

Basic Memory exposes these tools to any MCP client. Every tool is annotated with MCP behavior hints (read-only, destructive, idempotent, open-world) so agents can pick the right one without trial-and-error:

• Content: write_note, read_note, edit_note, move_note, delete_note, read_content, view_note
• Search & discovery: search_notes, recent_activity, list_directory
• Knowledge graph: build_context (navigates memory:// URLs)
• Projects: list_memory_projects, list_workspaces, create_memory_project, delete_project
• Schema: schema_infer, schema_validate, schema_diff
• Compatibility & diagnostics: search, fetch, basic_memory_diagnostics

All MCP tools default to text output; pass output_format="json" for structured responses. Full tool reference in the docs.

Routing flags (--local / --cloud) force a target when you're in mixed mode. Full CLI reference in the docs.

CLI installs check for updates every 24 hours by default and apply them silently (so the MCP server keeps responding).

• Supported install sources: uv tool, Homebrew
• Skipped for uvx (ephemeral runtime managed by uv)
• Manual: bm update (check + apply) or bm update --check (check only)

Disable in ~/.basic-memory/config.json:

{ "auto_update": false }

Minimal, anonymous events to understand the CLI-to-cloud conversion funnel.

What we collect: cloud promo impressions, cloud login attempts and outcomes, promo opt-out events.

What we don't: file contents, note titles, knowledge base data, PII, IP addresses, per-command or per-tool tracking.

Events go to our Umami Cloud instance (open-source, privacy-focused) on a background thread — never blocks the CLI.

Opt out:

export BASIC_MEMORY_NO_PROMOS=1

This disables promos and all telemetry.

Basic Memory uses Loguru. Defaults vary by entry point:

Log file: ~/.basic-memory/basic-memory.log (10MB rotation, 10 days retention).

BASIC_MEMORY_LOG_LEVEL=DEBUG basic-memory reindex
tail -f ~/.basic-memory/basic-memory.log

Basic Memory supports SQLite (default, fast, no Docker) and Postgres (via testcontainers — Docker required).

just install          # Install with dev dependencies
