Questions readers ask
The basics
Who is Kortex Daily for?
People who use AI tools at work: researchers, teachers, marketers, builders and anyone else who wants to keep up in five minutes. We skip deal flow and industry gossip unless it changes what you can do, buy or trust.
Is it free?
Yes. The email, the site and Kortex Daily Audio are free.
When does it arrive?
Weekday mornings at 6:00 AM Eastern. If that is too much, choose the Monday edition, which covers the week before.
What does Useful for mean?
Tags for the roles a story helps most: researchers, teachers, marketers, builders or everyone. Pick your role on the home page and the site puts those stories first.
Trust and corrections
Can I trust news written with AI?
Every claim has to match a linked source. An AI system drafts the story, then a second pass compares each claim with the sources and holds back any story that fails. Each story says it is AI-assisted, and the process is written out on How we work. How we work.
Which AI writes the stories?
A Claude model from Anthropic drafts them. How we work names the current model. What the AI does.
What happens to a story that fails the check?
It is held. It does not appear on the site, in the email or in any feed.
I found a mistake. What do I do?
Email kortexnotebooklm@gmail.com with the page address and what is wrong. We fix confirmed errors and update the story. How corrections work.
