Building a Whatsapp Clone | ChatGPT, Google Stitch, Google Ai Studio, Claude | Full Build 2026
In this video, I’m building Yessap, a WhatsApp-style messaging app, by coordinating multiple AI tools as a single product team. This is Part 1, focused on establishing the UI foundation, product logic, and backend structure using AI-driven workflows rather than traditional tutorials.
I use Google Stitch to design and build the UI foundation, Google AI Studio to define feature behavior and system logic, Claude to reason through backend architecture and how components connect, and ChatGPT to drive the prompting strategy that orchestrates the entire build.
This is not a coding tutorial. It’s a real-time demonstration of how modern applications can be planned and structured by intentionally combining AI systems, each with a clear responsibility.
What’s covered in Part 1:
Designing the Yessap UI foundation using Google Stitch
Building messaging screens, layouts, and interaction flows
Defining product behavior and feature logic with Google AI Studio
Planning backend architecture and system connections with Claude
Using ChatGPT to prompt, coordinate, and guide the AI workflow
Mapping core messaging features, data flow, and app structure
Converting an idea into a build-ready blueprint using AI
This series is for founders, designers, and builders interested in how AI can replace or accelerate early-stage product teams across UI, product, and backend planning.
