Which name best suites a platform in which users can seek advice from experts on a variety of life problems?

Yes. Hopefully you already own these domain names before publishing them like this but here's my 2 cents:

Crowdsage.com is pretty solid out of those options. All things being equal a .com is going to give you the edge in terms of credibility and many would argue SEO.

it does give you some minor problems that as a stand alone domain it's not clear whether you mean crowds age or "crowd sage" but it's not a bad name.

A brand is what you make it. A great name doesn't guarantee success by any measure but it can help you create a stickier brand and make you easier to find.

I've developed a process for coming up with names that works pretty well. It's a multi-step brainstorming process and it takes time but I would be happy to share it with you or even brainstorm together over Clarity.

Good luck with this.

First of all, never publish a list of names you're considering unless you already own them as domains. Frequently, somebody will learn about your intentions, then go register your target domains in order to sell them back to you for much steeper prices.

That's unethical, in my view; but it happens. Sometimes company employees or contractors (e.g. web designers) do this. So I'd be cautious even with internal communications. But definitely avoid public statements.

That said, I'm not recommending that people go out and buy each & every name candidate in advance. Obviously that would be wasteful.

It's clever embedding the "why" pun within "wise" in Whyse.Life. However, while it functions alright visually, it fails when the name is heard. Far too many ambiguities, between the creative misspelling and the novelty suffix.

CrowdSage.com is the clearest name in the list. No ambiguities or extra details to remember. The others aren't good enough for you. Whether CrowdSage.com is a good choice or not, I can't say without further research.

Also agree with Joseph regarding the risks of sharing names that you don't already own. For me, I'd say wisechat.co is the best. Why? It's two dictionary words, there's no ambiguity when saying it out loud, .co has become as respected as .com. The reason I'm not for crowdsage.com is that 'sage' is not a word used commonly so you could still have to explain it - and you never want to have to explain or spell your domain/email/company name. Same applies to the first two, and wisespace.me is phonetically poor with two 's'. That's IMHO anyway. Happy to discuss in detail over a call. Good luck!

There are two types of name you can choose. First is branded name, these names doesn't make sense but when we say it's like awesome, like instagram, oyo.
Second is all about when a people pronounce it, listener will surely understand what type of company or venture it is example twitter, Gmail.
