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

Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

Tell me what you're building. Let's self promote. Tell me what SaaS/App you're building or have built. I'll go first: I built Recume AI — you upload a photo of a car problem and get an instant AI diagnosis + repair cost estimate before you ever talk to a mechanic. Built it to close the trust gap between car owners and shops. Comment down below what you're building. Would love to check it out and give some honest feedback. submitted by /u/clever_coder777 to r/microsaas

I was tired of always having to check dog safety charts and weather reports whenever I wanted to walk my dog, so I made a quick tool to know when it's safe. (Yes, this is vibe coded, so take it with a grain of salt ;))
