Most knowledge work is fragmented by design. You research in a browser, think in a whiteboard, write in a doc, ask AI in a chat - then spend 20 minutes stitching it all back together. Dim0 keeps everything on one infinite canvas. What makes it different: The AI agent isn't a sidebar. It reads...

Questions & Answers

As answered by people managing Cert Decoder and Dim0.net.

What's the story behind your product?

Cert Decoder's answer

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

Dim0.net's answer:

Built solo by a developer working a full-time job. The frustration was personal - existing whiteboards are built for team collaboration, not individual thinking. None of them support rich text, math, and code together. And even powerful AI tools like ChatGPT leave your work scattered across hundreds of chat threads. Dim0 started as the tool that never existed: a canvas that acts as a center hub where research, documents, code, diagrams, and AI all live together.

Which are the primary technologies used for building your product?

Cert Decoder's answer

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

Dim0.net's answer:

TypeScript, React, Node.js. Supports multiple AI model providers including OpenAI, Anthropic, Google, Mistral, DeepSeek, Moonshot, and Qwen. Open source codebase available on GitHub.

How would you describe the primary audience of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Dim0.net's answer:

Researchers, founders, students, and builders who work through complex problems visually and feel frustrated by switching between too many tools. People who want one place to think, research, build, and present - without copy-pasting between a whiteboard, a doc, and an AI chat.

Why should a person choose your product over its competitors?

Cert Decoder's answer

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Dim0.net's answer:

Notion is great for docs but flat. Miro is great for collaboration but not for thinking alone. ChatGPT is powerful but buries your work in chat threads. Dim0 is the only tool where the AI agent reads your existing board context and writes directly back onto it. It supports rich text, math, code execution, mind maps, document chat, and presentation mode - all in one place. It is also fully open source and self-hostable, so you are never locked in.

Who are some of the biggest customers of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Dim0.net's answer:

  • Early access users including researchers and founders
  • Open source contributors via GitHub

What makes your product unique?

Dim0.net's answer:

Most canvas tools add AI as an add-on that feels disconnected from your work. Dim0 is built the other way around - the canvas is the interface, and the AI agent is native to it. The agent reads your actual board before acting, searches the web, runs code, and writes results back as live editable nodes. Everything stays connected: notes, diagrams, code, documents, widgets, and presentations all live on the same infinite surface without a single context switch.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
