Install CogniSphere
Five steps, and only one of them is strictly required after install.
- 1
Open the Chrome Web Store listing
Use the button below. The same listing works for Chrome and Edge.
- 2
Click “Add to Chrome”, then confirm
Chrome will list the permissions it needs to read the page you are on. Accept to continue.
- 3
Pin the icon
Click the puzzle-piece icon in the toolbar, find CogniSphere, and click the pin. This keeps it one click away.
- 4
Add an API key
Open the extension's settings and paste a key from Gemini, DeepSeek, OpenRouter, or point it at a local Ollama instance. This step is required — CogniSphere does not ship with a model.

Optional: sign in
An account only syncs your settings across devices and attaches a Pro plan. The extension works fully signed out.
Firefox users: the extension is built for Firefox too, but distribution there is not live yet. Ask us if you need a build.
