MutableAI

MutableAI for VS Code uses large scale neural networks trained on public data and metaprogramming to:

• Autocomplete your code
• Document your code
• You can also give instructions directly to the AI via a prompt!
• Refactor your code (beta)

We provide built-in fine-tuned support for a variety of languages such as Javascript/Typescript, Go, Rust, Python, Vue, Java etc. You can always add new languages under settings but the feature is experimental.

Getting started

1. Install the extension
   • If you want to try the latest and best features, install the pre-release version
   • If you want the most stable experience, install the standard release version
2. Click through the login pop-up browser option and follow it to mutable.ai; we recommend using login with Google or GitHub to avoid email verification.
3. You can also manually enter your API key from mutable.ai/account
4. Try out the commands

Watch for the extension status on the bottom right corner.

• mutable.ai: Not authenticated
  • Extension is enabled but not authenticated
• mutable.ai: Disabled
  • All functionality is disabled
• mutable.ai: Ready
  • Ready to use commands and autocomplete

To try out the extension, simply open any code file and press Control + Space. You should see some inline suggestions.

Pricing

• Free tier for individuals and open source devs 🎉
• Will charge for business and enterprise users
• Generous discounts for startups

Features

• All features depend on the language you work with. Some languages will have more features than others.
• We are constantly adding more features and more languages

▶️ MutableAI: Enable

If you missed the authentication popup, or you disabled the extension manually, you can enable the extension with this command.

⏸️ MutableAI: Disable

Manually disable the extension.

Inline autocomplete

Inline autocompletions will appear as you type. You can also manually invoke inline autocompletion.

Default trigger keys

• Short completion
  • Control + Space
• Long completion
  • Control + .

Note: You can change the hotkeys in "Keyboard Shortcuts" settings available in the command palette.

Full file transformations

These transformations operate on an entire file and are accessed through command palette (⌘ Command or ⌃ Control + Shift + P) and can be assigned hotkeys. We plan on adding a side panel in future versions.

• Note each transformation supports different filetypes by default. You can change the supported filetypes in the settings.
• You can accept or ignore the transformation suggestions in a carefully crafted custom-built diff view, where the original file is on the left and the transformed file is on the right.

Command Palette for MutableAI

🪄 MutableAI: Give a coding instruction

Limitations

Due to VS Code limitations

• The CodeLens button cannot appear above a deletion. (You can see it below instead)

Troubleshoot

If the extension is not working, try the following:

• Use "reset" command
• Enter API key manually
• Reinstall the extension
• Disable other extensions
• Restart VS Code
• Try switch between the release version and pre-release version

If still not working, contact us (support@mutable.ai) or using our chat on the website.

Other questions

About the API key

• The API key is stored securely with the VS Code secret storage API
• The API key is shared across a VS Code installation, so you don't need to login for different workspaces
• If you use some mechanism to sync extensions across different VS Code installations (on different machines), you will be prompted to login on the new machine

Extension Settings

• No extra settings added

Enjoy!
