Cosmo AI

Cosmo AI is a browser-native AI assistant rather than a standalone chatbot. Once installed, it adds a side panel and inline helpers to Chrome, so the assistant travels with you from site to site. The pitch is simplicity: instead of copying text into a separate AI tool and pasting the result back, you ask Cosmo directly on the page you are reading and use the output where you need it.

The feature set is aimed at everyday knowledge work. You can hold a general conversation with the assistant, generate long-form or social content, draft tweets with suggested hashtags, write replies to email, and produce LinkedIn posts such as hiring notices or company milestones. A select-and-ask behaviour lets you highlight a passage on any site and request a summary or explanation of just that text.

Cosmo AI is published by Nordfjord Limited and has been updated steadily through 2025. It is a lightweight extension, installs in a click, and is positioned as a general productivity layer for people who spend their working day inside the browser rather than in a dedicated writing app.
