1 Billion Brain Cells
Brain training drills run inside ChatGPT
Overview
What 1 Billion Brain Cells does
1 Billion Brain Cells is a mental exercise app from Spheric Admin Ltd that runs training drills inside an ordinary ChatGPT conversation. Sessions begin with a plain request, such as asking to work on recall, to practise vocabulary, or to sharpen focus, and the app is named in the prompt.
The example round given in the record is Odd One Out, a puzzle format rather than a lesson. Nothing in the listing describes scoring, stored progress, or difficulty settings, so what it covers is a set of short exercises held in conversation. The developer offers it as brain training rather than as structured coursework.
What stands out
The drills stay entirely in conversation, started by naming the app in the request.

Where 1 Billion Brain Cells is listed
1 Billion Brain Cells is listed in the ChatGPT apps directory only. Spheric Admin Ltd has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
