A GNKG seat is $49 early.
Metaphy LLC (Temecula, CA) sells one GNKG seat for $49 during early access. The later list price is $79. The seller is Metaphy LLC — not Google, and not the Chrome Web Store. NotebookLM and Gemini Notebook are trademarks of Google LLC; GNKG is an independent project.
Extension, console, and the agent harness
One seat covers one person’s GNKG use: the Chrome extension, the web console, and the MCP bridge plus harness files that ship with access. It is not a Google One or Gemini subscription.
Stripe or Lemon Squeezy — not chosen yet
The processor is still TBD. Until a checkout URL is set, Buy opens an email to logan@metaphysicsandcomputing.com with the subject “GNKG seat”. Card data is not collected on this page. Set GNKG_CHECKOUT_URL when rebuilding the site to point Buy at a real checkout.
14 days
Email logan@metaphysicsandcomputing.com within 14 days of purchase for a full refund of the seat fee. The Chrome Web Store does not process this payment and cannot refund it.
The Chrome Web Store listing, when it exists, is a separate unlisted, free install path so the extension has a stable ID and auto-update. Paying for a seat is a purchase from Metaphy LLC. Google is not the seller, not the merchant of record, and not a party to the refund.
