Hey DEV community! 👋

Just launched AI Flowchart Studio today — a tool that converts
plain English into professional flowcharts using a Multi-Agent
Gemini AI pipeline.

The Problem

Existing tools like Lucidchart are too heavy for quick diagrams.
I wanted something where you just DESCRIBE and it builds.

How the AI Works (4-Stage Pipeline)

This is the part I'm most proud of:

1. Orchestrator Agent — Validates if the prompt can logically become a flowchart
2. Logic Parser Agent — Breaks text into a structured JSON graph (nodes + edges)
3. Generator Agent — Converts the graph into Mermaid.js syntax
4. Syntax Validator — Final check to guarantee perfect visual output

This pipeline ensures "Garbage In" never becomes "Garbage Out" 🎯

Tech Stack

Frontend: Vanilla JS, Mermaid.js, html2canvas, CSS3
Glassmorphism — deployed on Vercel

Backend: FastAPI (Python), Google GenAI SDK,
Server-Sent Events for real-time streaming — deployed on Render

Key Features

• 🤖 Multi-Agent AI generation
• ✏️ Manual builder (click & type, no coding)
• 🔄 Undo/Redo engine with memory buffer
• 📤 Export PNG (3x super-scaled), SVG, or Mermaid code
• 💾 5 concurrent saved projects
• 📱 Mobile-responsive with bottom-sheet menus
• 🔍 Hardware-accelerated canvas zoom (+/- 300%)
• 🔑 BYOK — your API key never leaves your browser

Privacy First (BYOK)

Your Gemini API key is stored only in your browser's
LocalStorage. Our backend acts purely as a secure proxy —
zero data retention.

Would love feedback from devs:

• What would make you use this daily?
• Any architecture improvements you'd suggest?
• Would you pay for a hosted version (no API key needed)?

Thanks for reading! 🙏
