About

Who it is for

You use ChatGPT, Claude, Gemini or Perplexity to get your job done, and the tools change every week. Kortex Daily is for researchers, teachers, marketers and builders, plus anyone else who wants to keep up in five minutes without following the industry.

If you want deal flow, chip supply and executive news, other newsletters do that well. We cover money, chips and rules only when they change what you can do, buy or trust.

What every story gives you

• What it means for you. One or two plain sentences on what the news changes for your work, including when it changes nothing yet.
• Useful for. Tags for the roles the story helps most. Pick yours on the home page and the site follows.
• Sources. Every claim links to where it came from.

What is in the email

One short issue each weekday, or one on Monday if you prefer. It opens with Today in 5 minutes, then the big story, a few more stories, new tools to try and one-line links. It is built to be finished in five minutes. Read past issues on the site.

How stories are made

An AI system reads public sources and drafts each story. A second check compares every claim with those sources, and a story that fails the check is held back. Every story says it is AI-assisted. The full process, including what we do when we get something wrong, is on How we work.

Who is behind it

Kortex Daily is published by Kortex, the makers of a Chrome extension for ChatGPT, Claude, Gemini and Gemini Notebook. Our own promotions are marked "From Kortex" and only fill ad slots nobody bought. The news does not depend on them.
