| Description | Simon Willison's Newsletter is the email edition of Simon Willison's weblog, delivering a working open-source developer's first-hand accounts of testing new AI models, LLMs, and coding tools as they ship, alongside Python and software-engineering writing. It's aimed at developers and technical practitioners deciding which AI tools and models are actually worth using. Its main differentiator is independence and technical credibility: Willison isn't funded by the AI labs he covers, and his takes come from real hands-on experimentation rather than marketing. | ConvertKit (now Kit) is the email marketing platform built for creators. Used by 500,000+ bloggers, podcasters, YouTubers, and course creators to grow their audience, sell digital products, and run automated email funnels. |
