What is Bike4Mind?

Bike4Mind is an AI-powered knowledge platform that wires a superset of AI technologies together behind one workspace. Bring your own models, keep your data, and let agents do the heavy lifting.

• Notebooks — the core workspace: chat, documents, and context in one place, across any model.
• Multi-LLM by design — swap freely between Anthropic, OpenAI, Google Gemini, xAI, Ollama (local), and more, plus image models (FLUX, DALL·E 3, Stable Diffusion).
• Quest Master — autonomous, multi-step task planning: text and image generation, vision review, web search, math, code, and human-in-the-loop steps, run in parallel.
• AI Agents — autonomous ReAct-style agents that carry out complex tasks against your tools and knowledge.
• Knowledge Engine — RAG over your documents: smart chunking, vector search, collections, and tagging so agents can reason about what you know.
• Artifacts — reusable snippets, documents, and visualizations produced by agents, with a built-in publish-and-share layer.

Try the hosted service at app.bike4mind.com, or self-host the open core on your own infrastructure (below).

Open core

Bike4Mind is open core. The engine is public and self-hostable; the multi-tenant hosted service is our business.

• Open (this repo, BUSL-1.1): the agent engine, LLM adapters, CLI, data models, and the self-host path — published as @bike4mind/* packages.
• Commercial / closed: operating the multi-tenant hosted service — billing, entitlements, hosted infrastructure — and premium overlays such as Overwatch.

See CONTRIBUTING.md for the exact open/closed boundary.

Quickstart

Hosted (fastest): sign in at app.bike4mind.com — nothing to install.

Self-host: run the open core on your own hardware with Docker — no AWS account or cloud provider required. See the Self-Host Quickstart. In short:

# 1. Copy the env template, then generate JWT_SECRET / SESSION_SECRET /
#    SECRET_ENCRYPTION_KEY (see SELF_HOST.md) and add your model keys
cp .env.selfhost.example .env.selfhost

# 2. Bring up the stack (app + MongoDB + object storage + queues + mail catcher)
docker compose -f compose.selfhost.yaml --env-file .env.selfhost up -d

Bike4Mind then runs at http://localhost:3000; sign-in code emails land in the bundled Mailpit at http://localhost:8025. The self-host image is published to ghcr.io/bike4mind/bike4mind-selfhost.

Develop

Bike4Mind is a pnpm + Turborepo monorepo (Node 24).

pnpm i -r              # install
pnpm turbo:core:build  # build the @bike4mind/* core packages
pnpm turbo:typecheck   # type check
pnpm turbo:test        # run tests

Project layout: apps/client (Next.js SPA + pages API backend), packages/cli (interactive CLI + ReAct agent), b4m-core/* (the @bike4mind/* engine packages), packages/database (Mongoose models + migrations). Realtime WebSocket fanout ships as a separate @bike4mind/subscriber-fanout image. See CONTRIBUTING.md for the full guide.

Contributing

Contributions are welcome — fork → topic branch → PR → squash-merge. All contributors sign a lightweight CLA on their first PR (you keep your copyright). Start with CONTRIBUTING.md and our Code of Conduct. Questions and self-hosting help go in Discussions.

Security
