Mmh, looks like you need an account to use this search engine. Always not a good sign in terms of privacy but I might be wrong here. I'm currently using Presearch. It's decentralized (like Lemmy) and anonymizes your search queries. Most of it is Open Source but they announced to make everything Open Source in the future.

I discovered it some days ago too! It seems very interesting, but I don't feel like it worth a subscription ATM to mee (I'm using Brave search and it's a fine compromise). Saved the link though.

They also offer their own browser: https://browser.kagi.com/

I've been using it for a while, and I think as @ProfessorYakkington said, it depends on what you're using it for. I use it for work, and have work pay for it. In this case, I don't need absolute privacy, I need a contractual data guarantee, and their public TOS is (more than) sufficient for what I need for basic search.

It's hard to imagine a functional business relationship in most realms where the company you're doing business with has 0 knowledge of who you are, especially on the Internet. To provide search results kind of requires "knowing", at least for a second, what you're searching for. I think Kagi has a more private model for tailoring the results than traditional search. Instead of hidden filter bubbles, Kagi has transparent "lenses" you can choose to apply or not. The most useful one to me is the "forums" one, which refocuses on actual forums for results, like technet, askubuntu etc...

Not having to fight off ads, and having a pretty obvious method for them to make money(i.e. you pay them for service) is all to the good IMHO. The results seem to be on par with StartPage, with one difference. The forums lens is better at finding "real answers" for tech questions than StartPage which often finds the same "SPAM" results Google does. This is unsurprising as StartPage is anonymized Google. This may or may not be a good thing. If you're OK with ads or ad-blocking(you should be) - why pay for Kagi when you can use StartPage for free? The main reasons are to support a different search model, to get the lenses -especially forum focused, and for their GPT like results with citations.

Testing it right now and damn the results are quite impressive. But I have the same question as you, is it a good idea to use it?

I tried it but I found the results to be not as good as Google. I was trying to search for "phone loses connection" and one of the results was about losing weight. Google doesn't do that so I thought that was really weird.

I use kagi. I think it depends on your level of concern , as it does with most things. Kagi has a pretty nicely written privacy policy. They do require an account but I signed up with a masked email and cc. For my use I find their privacy policy enough given the other measures I take but the main reason I like kagi is zero ads or prioritized posting. Experiencing search with out ads is a pretty awesome exp in my opinion. There are other ways to get free search with ads stripped out but this “feel” fundamentally different from a service purpose built to be ad free and private. I am happy to pay for ad free platforms vs using platforms that are trying to do privacy preserving ads but this is more of a personal stance and preference. I know your question was more about privacy than ads but I find the two closely linked. I’ve attached a summary of their privacy policy below:

• Searches are anonymous and private to you. Kagi does not see what you are searching at all.
• We do not log or store your IP address. Your IP address is used only temporarily when enriching location/maps searches, and is not shared with any other party.
• We only store cookies needed for site functionality. We do not use any web browser analytics or other frontend telemetry.
• We do not display any ads, or have any first-party or third-party tracking in service of ads.
• We do not share customer data with third parties, except as needed to perform explicitly accessed services. In those cases, we will share the minimum amount of data needed to provide the service, and will do so in an anonymous way.
• We collect only the data needed to provide and protect the service.
• We proxy all images to prevent tracking from third parties.
• We use HTTPS encryption everywhere. All passwords are hashed and salted.

Been using it for a little over a year, I think. No complaints about the service itself, though its founder, Vlad, is of the opinion that moderation of search results is simultaneously a bad thing that should not be done, and a benefit to users, depending on context. Typical libertarian-brain in that sense.
