I found a tool called Next AI that links AI capabilities directly with diagrams. It lets you build and edit diagrams using natural language prompts instead of clicking around the canvas manually. It's a handy way to sketch out architecture when you don't want to drag every box yourself. The project is built on TypeScript with React 19 and Next.js. It supports multiple AI providers and even includes an MCP Server. This means you can use it with the Claude Code CLI to generate diagrams from your terminal. Deployment options are flexible too. You can run the tool locally with Docker or push it to Vercel and Cloudflare Workers. It supports multi provider setups so you can pick the backend that fits your workflow. #Nextjs #AI #Diagrams #TypeScript

Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial." It turned into a small portfolio of 5 sites, each aimed at a different kind of solo operator: Ledgerline: invoicing, contracts, and tax calculators for freelancers Rentline: rent increase letters, late fee calculators, and lease guides for landlords Sellerline:

The biggest AI app builder just dropped "vibe coding" from its messaging and pivoted to "trust" and "security." The market learned what healthcare builders already knew: when the data is PHI, vibes do not pass an audit. Free HIPAA scan:
