About

Founded by a filmmaker.
Not engineers.

Most AI tools were built by developers who got interested in writing. Vertical Clap® was built by a filmmaker who has been writing, developing and producing stories for years. The difference shows in every prompt, every structure, every product decision.

Sophie Attelann
Filmmaker · Founder of Vertical Clap®
« I spent years developing stories. Every tool I tried gave me generic text — dialogue that felt false, structure with no tension, zero understanding of narrative rhythm. I decided to build what I was looking for. »

Trained as a filmmaker, I developed fiction projects for various platforms before focusing on vertical format. This format — short, intense, designed for mobile — fascinated me as much for its creative constraints as for its reach potential.

Vertical Clap® was born from a creator's frustration with existing tools, and from the conviction that an AI trained by someone who understands storytelling can generate fundamentally different narratives.


The vision

The reference studio
for micro-drama creators.

Not a generalist tool. Not a content generator. A studio — with artistic direction, format understanding, and an obsession with dramatic tension and cliffhangers.

The Narrative Mixer™ isn't an algorithm. It's a filmmaker's narrative intuition codified: the conviction that the best stories emerge from the collision of elements you'd never have thought to combine.

Vertical Clap® should become what a human script editor would be for a solo creator — available at 3am, without judgment, always ready to generate the next episode.


Why micro-drama

The most demanding format
in contemporary storytelling.

60 seconds. A hook in the first 3. Rising tension. A cliffhanger that forces the next episode. No room for mediocrity — every second must justify its existence.

It's the format exploding on TikTok, DramaBox, ReelShort. And the hardest format to write — because it tolerates no weakness. Vertical Clap® is designed specifically for that.


The best way to understand Vertical Clap®
is to try it.
