Ask HN: What useful AI tools do you use every day?

I'm not the most versant AI user so far, I was wondering, what is currently the best tool for asking math questions (lessons, proofs, examples) ?

Haydari is a type of yogurt dish similar to a thick cacık, made from certain herbs and spices, combined with garlic and yogurt.[1] It differs from cacık in that the recipe contains no cucumber and calls for strained yogurt or labne.[2]

it is in the second sentence.

I'm experimenting with a somewhat similar workflow.

I have a Boox tablet I use to take handwritten notes on any relevant topics during the day. And with that I create the following workflow: 1. transform handwritten notes into a markdown document using chatgpt 2. with this document I ask chatgpt to create a summary of yesterdays activities and a list of unfinished things I still need to work on today.

This approach isn't perfect but is surprisingly useful.

Kagi Translate.

Kagi Summarizer (via bookmarklet) to help weed out articles that won't be worth reading (even here on HN) or to get the one sentence that matters.

Kagi Assistant. This I use for random things, like pasting a webpage's source and having it figure out what to fill in on this form to make an RSS feed where none exists.[1] (This, in my current push to move most of my needed information updates both out of email and into RSS, as well as to reverse what I call "the arrow of information" [I want to batch-check information updates on a schedule instead of getting interrupted by incoming data piecemeal].)

Kagi Assistant (and the various LLM models) are also great when I realize that I don't understand a particular grammar or usage point in a foreign language that I'm learning: the models usually create clear explanations and then a few practice exercises for me to do.
