Free, every weekday. ## What Kortex Daily is Kortex Daily is a free email, website and audio show from Kortex (https://www.kortex-notebooklm.com) about AI news for people who use AI at work. Every story links its sources, and says what it means for the reader. Stories are drafted by an AI system and checked against those sources before they go live. ## Who it is for Researchers, teachers, marketers, builders and other people who use ChatGPT, Claude, Gemini, Copilot, Perplexity and similar tools to do their jobs. It is not written for investors or industry watchers; money, chips and rules appear only when they change what a reader can do, buy or trust. ## Sections and their newest stories ### Your AI assistants What changed in ChatGPT, Claude, Gemini, Copilot, Perplexity and Gemini Notebook: features, plans and limits.
