Nvidia is expanding the reach of its AI assistant, G-Assist, beyond gaming optimization by introducing plugin support that turns it into a full-fledged digital assistant on Windows. Originally launched last month as a gaming-focused tool, G-Assist now integrates with popular services like Spotify, Twitch, and even smart RGB hardware—thanks to a newly released plugin system powered by local AI processing.
The update allows G-Assist to interact with external applications and APIs, enabling users to perform a wide variety of tasks with simple voice or typed commands. These include hands-free control of Spotify, real-time stock updates, checking weather conditions, monitoring if a streamer is live on Twitch, and even adjusting RGB lighting or fan speeds on supported peripherals from Logitech G, Corsair, MSI, and Nanoleaf.
These capabilities come through a new plugin builder based on ChatGPT technology, letting developers and enthusiasts create and share custom plugins. Nvidia has released sample plugins via GitHub that can be installed and modified, turning G-Assist into a customizable personal assistant tailored to individual setups.
Here’s what the new plugins can currently do:
Unlike most cloud-based AI assistants, G-Assist runs locally using a small language model hosted on Nvidia’s RTX GPUs. It requires approximately 10GB of space to function fully, including support for voice recognition and responses. The assistant currently supports RTX 30-, 40-, and 50-series desktop GPUs, though a minimum of 12GB of VRAM is required for optimal performance.
This local-first approach means users retain more control over their data and benefit from near-instantaneous response times, without relying on cloud connectivity. It also ensures G-Assist can continue working even when offline, a rare feature in today’s AI assistant market.
G-Assist is available as an optional install within Nvidia’s main app for Windows. Developers interested in crafting their own plugins can access full documentation and starter templates via Nvidia’s GitHub repository, fostering a community-driven expansion of the assistant’s capabilities.
With this move, Nvidia is positioning G-Assist not just as a gaming companion, but as a powerful AI tool for PC enthusiasts who want voice-driven access to their apps, devices, and data—all running on the hardware they already own.
