All decent inference servers, including Ollama, support that API." (Translation) https://github.com/Mail-0/Zero/issues/948#issuecomment-2890497890

Points to Note

When you connect Gmail, the app requests full access to your inbox. The README states that data transferred to external services is subject to those services' policies. In the source code, only the Google login is enabled, while the Microsoft section is commented out. It requires Google Cloud and Autumn keys, and it’s an early-stage product with only one public release, v0.1.
