Cosma: A Creator's Genesis

From a tear to a cosmos: a cinematic spec ad about breaking free from creative limits with Cosma, an AI worldbuilding engine that lets creators sketch worlds into existence beyond technical barriers.

Inspiration

This film comes from a long, quiet fight with invisible rules.

As a kid and later as a gamer, I tasted what it felt like to be judged first by skill and presence, not by gender, appearance, or background. In certain virtual worlds, I was treated like “one of the guys” again — until bias, expectations, and tools slowly crept back in and decided who was “allowed” to be technical, to lead, to build.

The line, “Trapped in a reality built by their rules,” and the drop of tear into the desert are my shorthand for that loss.

Cosma: A Creator’s Genesis is my answer: a small myth about a creator who turns that tear into a cosmos, and finally writes her own rules with an AI worldbuilding engine for game worlds.

The core belief is simple:

If we lower the technical walls around game worldbuilding, more people can create realities where imagination — not inherited rules — sets the limits for what people get to experience.

What it does

This is a cinematic spec ad for Cosma, an AI worldbuilding engine for game creators and worldbuilders.

In the film, a burned-out creator:

  • drowns in red Error messages under a single lit window,
  • touches a starfield that explodes into a cosmos,
  • unfolds Cosma’s holographic UI like a constellation,
  • sketches a 2D level layout and watches it rise into a 3D island,
  • drops a “World DNA” strand that reskins the same geography from realistic jungle into a glowing violet forest,
  • and watches the camera pull back to reveal that her island is only one of many floating worlds in a shared cosmos — a metaphor for a cosmopolitan community of creators in the Cosma ecosystem, where AI removes technical barriers.

Rather than listing features, the ad shows one clear promise: Sketch a world in 2D, explore it in 3D, and restyle the same playable space without fighting a wall of tools — Cosma makes imagination the only rule for game worlds.

How we built it

I built this as a solo founder–director, using a hybrid custom workflows and Kling AI.

  1. Story-first I structured the film around three beats: trapped → contact → agency. Every shot — from the window and desert to the tear, cosmos, island and multiverse — was designed to serve that emotional arc and feel like a teaser for an unmade virtual universe.

  2. Myth aligned with product The holographic UI, 2D to 3D island and World DNA sequence mirror interaction patterns we’re building toward in the actual Cosma’s product.

  3. AI-driven visuals, directed like a crew I used custom workflows and custom-trained diffusion models to generate key frames, animated them using Kling AI, and then composited everything with traditional editing.

Fun facts:

  • For my on-screen “digital twin” alone, I trained two separate AI models: one for extremely detailed, realistic close-up shots that look nearly identical to me in real life, and one for full-body shots that accurately mirror my actual body shape.
  • The custom workflow I’ve built at Cosma gives me shot-level control over composition, instead of prompting AI like a “slot machine.”
  1. Edit & sound From the tear onward, every cut and zoom is timed to the music.

Challenges we ran into

  • Balancing poetry with marketing clarity
  • Directing it into a strict narrative within a short timeline as a solo creator.

Accomplishments that we're proud of

  1. A spec ad that still feels like a story The film works as a short myth about breaking “their rules”, yet clearly reads as an ad for an AI worldbuilding engine aimed at game creators and worldbuilders, not just a generic AI visualizer.

  2. Putting product truth inside a cinematic wrapper The 2D to 3D worldbuilding and World DNA reskin aren’t arbitrary VFX — they visualize real workflows Cosma is being designed to support for rapid level prototyping and restyling.

  3. End-to-end as a solo founder Writing, acting, art direction, AI production, compositing and edit were all done by one person while building the underlying tool. Seeing other game devs and creators say “this feels exactly like hitting creative walls” is the accomplishment I care about most.

What we learned

  1. Emotion is the strongest prompt The most compelling shots came from anchoring AI generation in feelings — despair, contact, liberation — rather than over-detailed descriptions.

  2. Narrative anchors AI’s chaos A clear story arc saved me from infinite possibilities. It became the filter for which AI outputs to keep, how to cut them, and how to make them feel intentional.

  3. Brand = belief + one honest capability For this piece, the belief is “your imagination is the only rule”; the capability is sketch-to-world with swappable styles for game worlds. That combination was enough to carry both the ad and the product.

What's next for Cosma: A Creator's Genesis

This film is chapter one.

From cinematic to actual product Keep building the product so creators not only can see their worlds coming true, but also can play, iterate, and ship them.

From one creator’s myth to many Opening this workflow to more artists, writers and game designers who have also felt “trapped by their rules,” so they can host worlds of their own.

The long-term vision stays simple: More people, in more places, able to build and live in game worlds and virtual spaces where imagination — not inherited rules or technical gatekeeping — decides what’s possible.
