VoiceDraw – Talk system design out loud, the diagrams draw themselves
I was frustated by having to draw system design diagrams by hand when discussing it with my team mates or in an interview. So I thought "Wouldn't it be great if someone draws it for me, while I think out loud?". That is when I came up with VoiceDraw. You can just think out loud or discuss your system architecture with a friend/interviewer, the diagrams are automatically drawn along with your reasoning, open questions and tradeoffs beautifully written on to the side.

In plain words
VoiceDraw automatically converts spoken discussions about system architecture into visual diagrams. Users describe their design ideas aloud while the tool simultaneously generates corresponding diagrams and documents reasoning, open questions, and tradeoffs alongside the visuals. It is designed for software engineers discussing designs with teammates or preparing for system design interviews, eliminating the need to manually sketch while thinking through problems.

Hello HN, It has been a while since I contributed to the web, so I decided to get back in shape and publish "something". This app is a POC of "what if diagrams were more dynamic". I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems. I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;) As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their…
- DADiagram as code tool with draggable customizationsOct 2025 · github.com · ▲266
In the past I've used declarative diagram generation tools like Mermaid.js a lot for quickly drawing up things but for presentations or deliverables I find that I have to then move the generated diagrams over to a tool like Lucidchart which allows full control of the organization and customization. Therefore I am now working on this to combine the benefits of both into just one tool which can do both functions. The project is certainly in the early stages but if you find yourself making architecture diagrams I'd love to hear your thoughts on the idea or even a Github issue for a feature…
- ADAgent Draw: An agent draws while you talk, built on TLDrawJul 2026 · techstackups.com · ▲53
We recently built 2draw, a Drawful-style game where players draw on a shared canvas and race to guess each other's drawings, on tldraw, an infinite-canvas SDK for React. We started wondering what it would take to put an agent in that loop, as an opponent or a rival guesser, and dug into how an agent could read and draw on a tldraw canvas. That research turned into: Agent draw, a tool that lets an agent draw to the canvas for you while you present. You can try it right now, or grab the source: - Live demo: https://tldraw-agent-draw-demo.james-664.workers.dev - Source:…
- TATalkNotes – A site that turns your ideas into tasks2025 · talknotes.tech · ▲103
Hey all! I created TalkNotes few weeks ago and it started getting traction in hours. It quickly went from 0 -> $700 revenue with One time payment and I decided to remove the one time payment, the line went straight down but since then it rising little by little and has now reached $150 MRR. I'm stoked since this is one of my best projects. The idea is to speak freely into a microphone about anything on your mind—meetings, emails, tasks—and let AI help organize it all. It turns your thoughts into a structured to-do list, notes, flashcards, and more. I created it because spending 15 minutes…
