I’ve been playing with cogmi for a week and it’s really cool what insights it’s giving me about performance. Usually I don’t even think about when to stop, but now there’s some data to focus on. It’s like keeping tabs on circardian rhythm but for brain performance.

Pretty good, I like the process. I did run into a couple questions that were worded weirdly or just had odd answer logic (it'll mark you wrong for the tiniest typo). Would be cool if it had a bit more wiggle room or a way to flag those. But still, definitely helpful.

Would recommend this to anyone. Writing things down is great, but being able to freely talk about it is even better. It gives you time to get it all out and a lot of times I feel better just by verbalizing issues out loud. I really appreciate that the report from the session reflects everything I've said in a structured way, so I don't have to worry about talking super coherently. It also provides useful insights and recommendations. The whole self-care topic has always sounded like a chore to me but I actually enjoy this.

Wow is all I can really think. I am literally at a loss for praiseworthy words. Context Minds has truly set the bar and blown me away. There is nothing that I can think of that would improve it. It is awesome and so user-friendly. It really is everything you could want in such an app. Good jobs guys!!!
