I built a tool to diagram your ideas – no login, no syntax, just chat

Introducing Codigram: A Simplified, No-Fuss Tool for Creating Diagrams Through Conversation

Visual aids like diagrams are invaluable for brainstorming, planning, and clarifying complex ideas. Many professionals and enthusiasts turn to tools like Mermaid.js to craft these visuals, but the traditional workflows often involve juggling syntax documentation, external editors, and multiple tools—factors that can hinder productivity and creativity.

Recognizing these challenges, I developed Codigram, a browser-based application designed to streamline the process of diagram creation. With Codigram, you can describe your ideas in plain language, chat with the tool, and watch your instructions transform into polished diagrams—all without the need for logging in or setting up complex environments.

Key Features of Codigram

Natural Language Input: Start by typing your ideas in straightforward English. Codigram interprets your description and converts it seamlessly into Mermaid.js code, turning conceptual thoughts into visual diagrams effortlessly.
Interactive Editing: Prefer more control? Use the built-in code editor with syntax highlighting to tweak your Mermaid.js code directly. The diagram updates in real-time, providing immediate visual feedback on your adjustments.
Live Synchronization: As you write or modify the code or descriptions, the diagram refreshes instantly. This immediate visual response helps you iterate quickly and intuitively.
Error Handling & Beautification: Encounter issues? Use the auto-fix or beautify options with a single click, ensuring your code remains clean and functional without hassle.
Diagram Explanation: Need clarity? Codigram can generate plain English explanations of your diagrams, aiding understanding and presentation.
Export Options: Save your work effortlessly as PNG, SVG, or raw Mermaid.js code. Projects are stored locally in your browser, ensuring privacy and ease of access without account dependencies.

Who Is It For?

Codigram is ideal for anyone who thinks visually but prefers typing or conversational interfaces over dragging and dropping elements. Whether you’re a developer, educator, or creative thinker, this tool simplifies the diagramming process, making it accessible and frictionless.

Technical Foundations

Built using React and leveraging Gemini 2.5 Flash, Codigram is designed to be fast, responsive, and intuitive. Its architecture emphasizes minimal setup to maximize your focus on ideas rather than tools.
