I'm also sadly disgruntled by this change. I love kagi. I bought the socks and tell everyone I know about it.
Kagi is the best search experience today - by far. If kagi went away, I might be forced to start my own business to replace it.
And the assistant? Was fine, worked great for me.
I don't care too much about the new ui (though there's a few regressions already mentioned in this thread). But I do care about losing my data, and how kagi is choosing to operate. You've removed my data, with no way to export and no clear reason why. Kagi staff didn't even reply: https://kagifeedback.org/d/10713-bring-back-tags-in-assistant/6
The 4% of users with 2+ tags likely represent some of your most influential and dedicated users. Their impact on your business is outsized in various ways but it doesn't seem like a good idea to upset them. This concerns me because I care about the future of kagi.
Overall, I'm upset that no one at kagi appears to be listening to these concerns or taking them seriously. I genuinely don't understand - if you wanted to make folders the default, with an option for tags buried deeply in the settings ui (and advertsides nowhere), what harm could that possibly cause?
As a business lesson - forced ui overhauls are rarely (practically never) received well. Redesigns typically remove features and reduce stability - I personally ran into a bug today where code output from the code agent is completely malformed because my inputs included a triple backtick code block inside a comment. So unless there is a gripping technical reason to do so, redesigns such as this should not be done, or should be made optional for as long as possible - even without the deletion of user data.
If there is a strong technical reason that the old ui needed to be removed - I don't see how that could possibly be related to the folders/tags change. Maybe an outdated client library? But it would have been ideal to split these changes into two releases.
I don't have any real recourse here - I'm sold on kagi for the foreseeable future. Maybe I'll downgrade to search only. But in my view, kagi's reputation as a users-first organization has been tarnished. And I won't be as vocal about recommending kagi going forward, lets my own reputation be tarnished.
Maybe this was a small enough change that it was truly not known by leadership - but that in itself is imo a red flag for how feedback is being surfaced to the product team. The fact that forced adoption was delayed by a couple weeks tells me this is likely not the case.
In any case, to restore kagi's reputation in my mind, we need clear communication on what led to this change, why it was important to remove our data and existing functionality without optionality, and why there was no response to users given the feedback we surfaced.
As of now, I don't have a lot of confidence to invest in kagi's ecosystem given my investments have not been respected so far.
