NimPilot
An AI coding assistant for VS Code, powered by NVIDIA NIM.
Features
Chat sidebar — streaming responses, conversation history (search/pin/rename/delete/export/import), and an agentic tool-calling loop the model can use to:
- Read, create, and edit files in your workspace (
write_file and run_terminal_command always require your explicit approval before running — nothing touches disk or a shell without a click)
- Run terminal commands (builds, tests, installs, git)
- Attach an image (or paste one with Ctrl+V) — read directly by the model
- Attach a document (PDF, Word, PowerPoint, or plain text) — extracted and indexed into a local RAG index so the model can answer questions about it
- Search a RAG index built over your whole workspace (
NimPilot: Index Workspace) for relevant code context automatically

Quick start
npm install
npm run build # bundles the extension host + webview
Press F5 in VS Code to launch an Extension Development Host with it loaded, or package it:
npx vsce package
code --install-extension nimpilot-0.1.0.vsix
Then run NimPilot: Set API Key from the Command Palette and paste your NVIDIA NIM API key — it's stored in your OS keychain via VS Code SecretStorage, never written to disk in plain text.
Getting an NVIDIA API key
- Go to build.nvidia.com and create an account using any email address.
- Verify that email address (check your inbox for the confirmation link).
- Verify your account with a mobile phone number when prompted (required before API key generation is unlocked).
- Once verified, open your account/profile menu and generate a new API key.
- Copy the key, then in VS Code run
NimPilot: Set API Key from the Command Palette and paste it in — the extension uses this key to authenticate all requests to NVIDIA NIM.
- Press Ctrl+Shift+P, type Open Chat, and select it to start using the extension.
