// how it works

How it works

  1. Clarify your goal

    Decide the first concrete outcome you want from it, so you can pick the right example, template or mode instead of exploring everything at once.

  2. Get the project

    Clone the repository (or install the published package) and skim its README quick start for the requirements for your platform.

  3. Install and configure

    Run the documented install step and set any required configuration — such as provider keys, data sources or local services — before the first run.

  4. Run your first task

    Execute the smallest documented example end to end, confirm the output is what you expected, then adapt it to your real data or workflow.

// features

// run it

Run it yourself

  1. Clone the repository

    Get the source so you can inspect, configure and run it locally.

    git clone https://github.com/johnbean393/Sidekick.git
    cd Sidekick
  2. Install Sidekick

    Install the cask via Homebrew, or download the app from the project site/Releases.

    brew install --cask arcadi4/tap/sidekick-ai
  3. Open and chat locally

    Launch Sidekick, let it load a local model, and point it at a folder or website to start asking questions.

    # Open Sidekick.app and follow the in-app setup — see README Installation

Questions, answered

Who maintains Sidekick?

It is maintained by johnbean393 on GitHub (johnbean393/Sidekick), where the source, issues and releases live.

Is it free to use?

Yes — it is free and open source under the MIT licence, which permits use, modification and redistribution, including commercially, with attribution.

Does it need a paid API key?

No key is required for local models; an API key is only needed if you choose to add a cloud provider.

How does it compare to LM Studio or Ollama plus a separate chat UI?

Compared with LM Studio or Ollama plus a separate chat UI, Sidekick's distinguishing focus is: a native macOS app to chat with a local LLM over your own files, folders and websites. Pick it when that focus matches your need; the alternative may suit you better if its broader or different scope is the priority.

How do I get started?

Clone https://github.com/johnbean393/Sidekick (or install its published package), follow the README quick start to install and configure it, then run the smallest documented example — the Run section on this page mirrors those steps.
