Features

Installation

To get started, just download the appropriate Lightrail package for your operating system:

Usage

  • Launch Lightrail initially as you would normally start an application on your platform (i.e. from your application launcher). Consider adding it to your startup items (OS X, Gnome), so that it automatically starts on boot.
  • When Lightrail is running on your system, it can be activated at any time by pressing the keyboard combination Cmd/Ctrl-Shift-Space.
  • Use the up- and down-arrow keys to browse actions, and hit enter/return to select one (while in 'Choose an action' mode).
  • To change the action afterwards, press esc or @, or click on the current action
  • After selecting an action, enter the prompt (or any other required arguments). Your prompt can include special Tokens, which pull in additional context from external sources:
    • Type the forward-slash at any point in a prompt (/) to open the Tokens menu. Use the arrow keys to select a token and hit enter to insert that token into your prompt.
    • In general, try to be explicit about what sources of content you'd like to include for best results.
  • Cmd/Ctrl-Up and Cmd/Ctrl-Down cycle through the prompt history.
  • By default, the application uses a lightrail.ai-provided gateway to access OpenAI's LLMs. If you'd like to switch to using your own API key and accessing the OpenAI API directly, you can configure that in Settings (click the gear icon in the prompt input box).

Troubleshooting

Some common issues, and how to fix them:

  • Q: I get i is not iterable as an error
  • A: This occurs when the action expects a prompt but one isn't provided. Almost all actions currently available only work if the user has entered a prompt, so make sure you're providing one before you hit enter/return.
  • Q: I'm on Linux and the keyboard shortcut to open Lightrail isn't working for me
  • A: If you're using Wayland, this is a known bug, caused by this issue. Currently, the only fix is using your system's settings to manually assign a keyboard shortcut to launching Lightrail. If you have any idea how to work-around this bug, I'd love to hear it!

Any other issues? Let me know on Discord or make an issue and I'll address it ASAP!

Reporting Bugs

When creating an issue or describing a but on Discord, please include the contents of the Lightrail log file, available at the following location:

  • on Linux: ~/.config/lightrail-core/logs/main.log
  • on macOS: ~/Library/Logs/lightrail-core/main.log

Writing Tracks & Clients

The lightrail-sdk npm package makes it easy to create additional tracks and extend Lightrail's functionality, or to make Clients that integrate Lightrail with other platforms. For thorough documentation on creating Tracks & Clients, see our developer documentation here.
