As a user myself, I'm not sure. Assistant is a separate view so it's easy to never interact with it but yeah, I can see why that might be a work policy issue. You could try requesting that as a feature in https://kagifeedback.org. The team are quite responsive there and historically Vlad the CEO reads every post.
Curious is it no AI or no LLMs policy? Search has used some form of AI since inception.
Are you imagining one switch toggle that would disable it at the team account level (or individual account level - in which case it would theoratically still be opt-in and 'available' like it is now).
Genuinly trying to understand the UX of it that would comply with the policy.
Then you shouldn’t have been using Kagi in the first place, because they’ve always had an AI summarizer feature available by appending a question mark to the query. So just like you can choose not to use that, which has always been there, you can choose not to click on Assistant and stick only to non-AI functionality.
