PartGenie for Chrome recognizes the MPN on a supported distributor or manufacturer product page. Alternatives, datasheet chat, ECAD, and price comparison stay in a sidebar beside the part—no copy-paste into a new tab. Install from the Chrome Web Store.

​
Install and sign in

1

Install the extension

Open the PartGenie listing in the Chrome Web Store and click Add to Chrome. Pin the PartGenie icon in the toolbar if you use it often.
2

Sign in

Click the PartGenie icon or open the sidebar on a supported product page. Sign in with the same account you use at app.partgenie.ai.
3

Open a supported product page

Navigate to a product detail page on a supported site (for example DigiKey, Mouser, or LCSC). PartGenie reads the MPN from the page and loads research for that exact part.
The extension only runs component assistance on supported pages. It does not inject into unrelated sites.

​
Use the sidebar

PartGenie Chrome extension on a DigiKey product page: alternatives table, CAD models, Find alternatives, Compare prices, and Ask about this part
When the sidebar opens on a product page: Alternatives include supporting evidence—not only parametric tables. Use the cited sources before you swap a part in production.

​
Floating toolbar

PartGenie floating toolbar on a distributor page: component details, alternatives, and price comparison shortcuts
On some pages a compact floating toolbar appears at the edge of the window. Use it to open component details, alternatives, or price comparison without hunting for the main extension icon. Close it with × when you want a clear view of the distributor page.

​
ECAD from the extension

From CAD models in the sidebar:
  1. Download symbol, footprint, or 3D from the catalog when CAD Models has files for this MPN.
  2. Or start KiCad library generation (Beta) and download when ready.
Import steps for your EDA tool: EDA integration.

​
Open the full web app

Use links in the sidebar to open the full PartGenie component page or continue in Search when you need Projects, BOM, Design, or Knowledge.

​
Supported sites

Today includes major distributors such as DigiKey, Mouser, and LCSC, plus additional manufacturer and distributor pages PartGenie recognizes. Coverage expands over time; if a page you rely on is missing, tell us at [email protected].

​
Privacy and permissions

The extension needs access to supported product pages so it can read the MPN and page context required to identify the component. It does not replace your distributor login or place orders for you—Purchase links open the distributor’s own checkout flow.
