help Cosine FAQ

How does Cosine bring spreadsheet or database data into Claude?

Cosine is presented as a connector layer that exposes selected external information to a Claude conversation. The exact setup depends on whether the source is Google Sheets, a database, or an HTTP API, and each source requires its own authorization.

Does Cosine permanently train Claude on connected company data?

Connecting a source is not the same as retraining Claude's underlying model. The extension retrieves relevant information for a conversation, while retention and access behavior depend on Cosine's and Claude's current privacy settings.

Can Cosine use live API results rather than a static upload?

Its stated purpose includes bringing API data into Claude, which can provide fresher results than uploading a fixed CSV file. Whether the data is truly real time depends on the connector's refresh and caching behavior.

What permissions should be checked before connecting Cosine to business data?

Users should verify whether the connector receives read-only or write access, which tables or sheets it can reach, and how credentials are stored. A limited service account or narrowly shared Google Sheet is safer than granting access to an entire workspace.
