Second Brain Python Packages

brain-framework

🧠 Brain Framework: from information to informed actions.

brain-mcp

The recorder for your AI conversations — local-first MCP memory that keeps byte-exact copies of your Claude Code, Codex and Pi sessions (Claude Code deletes its own after 30 days) and answers with a citation or abstains. DuckDB.

obsidian-wiki

Framework for AI agents to build and maintain a digital brain through Obsidian wiki | Memory System for Agents

memstem

Unified memory and skill infrastructure for AI agents — pull-based ingestion across Claude Code, OpenClaw, Codex, Cursor, and more. Markdown canonical + SQLite hybrid index + MCP-native API.

kluris

Turn AI agents into team SMEs. Kluris builds a shared, human-curated knowledge brain (decisions, constraints, incidents, tribal knowledge) as markdown in a git repo. Queryable via slash commands from Claude Code, Codex, Cursor, Windsurf, Cline, Gemini CLI.

openkos

Local-first engine that turns your scattered text into a living, portable knowledge base in the Open Knowledge Format (OKF)

mcp-logseq

MCP server to interact with LogSeq via its Local HTTP API - enabling AI assistants like Claude to seamlessly read, write, and manage your LogSeq graph.

lifeos-cli

Terminal-native LifeOS with an optional local Web UI for tasks, notes, habits, schedules, timelogs, relationships, and human-agent collaboration.

loci-rag

A queryable second brain over your scattered notes and docs - hybrid retrieval (vector + BM25), section-level citations, and an MCP server so AI agents can use it. ~300 lines, no LangChain.

claude-ns-hub

Drop a task. Walk away. Come back to results. Local Claude Code session orchestrator — Stone queue, multi-session dispatch, push notifications.

atlas-mind

Self-hostable, git-native knowledge base & AI memory (MCP) — your notes stay plain Markdown files in your own git repo. Pure-stdlib Python, no database. AGPL-3.0.

zttl

Zettelkasten knowledge base for repos

weftgate

New session. Same project brain. Local memory, compact context and handoffs for coding agents, with verification built in. One install. CLI + MCP.

fkf

🧠 AI Brain Factory: from information to informed action. Not for 🐙 mindflayers or 🧟 zombies.

palimpsest-notion

Keeps a Notion workspace or Obsidian vault up to date as you read. Extracts claims from a source, works out how each relates to your notes, and applies small, cited, reversible edits.

notionmemory

Notion-backed long-term memory, calendar, and knowledge retrieval for AI agents.

matryca-plumber

Local-first AI daemon for Logseq OG: background semantic indexing, link hygiene, and agent-ready CLI/MCP — edits Markdown on disk (no cloud, no Logseq API). Karpathy LLM-Wiki inspired.

esbi-cli

Turns the PDFs, links and emails you save into a Markdown wiki written by a local or cloud language model. Command: sb

synto

More than just Karpathy’s LLM Wiki, 100% local with Ollama. Drop Markdown notes → AI extracts concepts → your Obsidian wiki auto-links and grows. Zero sharing. Your notes stay yours.

personal-instagram-library

PIL — Personal Instagram Library: an installable Muse skill that turns your Instagram saved posts into a private, queryable knowledge base. Code is shared, data stays home.

cairn-remembers

Local-first memory for you and your AI. One SQLite vault on your computer, shared across local and cloud AI tools through MCP or the CLI.

root-kg

Your knowledge graph. Ask questions across all your notes, meetings and emails, and get cited answers.

scrip-harness

Agent-compiled knowledge base: compile/cache/retrieve as one answer ladder, with computable staleness and machine-verifiable provenance.

obsidian-llm-wiki

Karpathy’s LLM Wiki, 100% local with Ollama. Drop Markdown notes → AI extracts concepts → your Obsidian wiki auto-links and grows. Zero sharing. Your notes stay yours.
