Sellio Chat

I spent the last 4 months building Sellio, an all-in-one customer experience platform that brings live chat, a shared inbox, and AI agents into one place.

The idea was simple: customer conversations shouldn't be scattered across different tools, and AI shouldn't replace human support unless you want it to.

What I built:

• Shared inbox to manage customer conversations in one place
• AI agents trained on your own knowledge base
• Live chat widget with a simple one-line installation
• Human takeover whenever a conversation needs a personal touch
• Help center, analytics, contacts, and workflow automations
• Desktop and mobile apps to manage conversations on the go

Tech stack: Next.js, React, TypeScript, Tailwind CSS, Bun, PostgreSQL, and Tauri.

The biggest challenge: Building a complete SaaS as a solo founder, from designing the interface and implementing real-time messaging to integrating AI agents and keeping the experience simple.

After 4 months of designing, coding, debugging, and shipping, Sellio is finally live!
