FablAI — AI Story Generation Platform (Web + iOS + Android)

I designed and built FablAI completely from scratch as a solo founder and full-stack developer.

FablAI is a production AI application that generates fully illustrated, multi-page stories in seconds — including text, images, voice-over and exportable formats.

This is not a prototype.

It is a complete SaaS + mobile app ecosystem currently in production.

What the product does

FablAI allows users to create personalized stories end-to-end:

• Generate story text using AI

• Generate consistent illustrations for every page

• Upload a photo so a child (or the user) becomes the protagonist

• Generate voice-over narration with multiple styles

• Export stories as PDFs or share to social media

• Manage a personal library of stories

• Create content in 13 languages

The app is used for:

• Kids storytelling

• Educational content (history, science, economics…)

• Personalized content generation

• Audiobook creation

Platforms delivered

I built the entire ecosystem:
