Privacy concerns are valid when an external server needs to be queried, like if you were to use DeepL or Google Translate for this stuff, or for any LLM related muck, but they have been accounting for this already by making things work locally. For example, translations performed fully on device, and are an example of a feature I wanted.

Like many here, the entire AI browser idea doesn’t appeal to me at all, but I also struggle to come up with ‘features their users want’ if I take myself as an example. I have previously used Vivaldi, and while it is much more full featured, it doesn’t add any features that I actually end up using frequently.
