Available01 / The problem
Documentary production is fragmented.
SYSTEM / 01Research lives in one place. Writing in another. Visual development somewhere else. Assets scatter, timelines drift, and editing starts before the production structure exists.
Modern AI can generate individual pieces. Butterfly Engine is built to connect them into one coherent production system.
The next leap is not a better generator. It is a system that knows what to do next.
02 / The engine
From one event to a complete documentary.
A connected pipeline from historical input to a reproducible project. Every stage leaves an artifact the next stage can use.

07 / FAQ
Questions, answered.
What is Butterfly Engine?
Butterfly Engine is an AI-native documentary production engine built by Kadir Sel. It converts a historical event or original idea into a structured story, visual prompts, production assets, a timeline and a rendered documentary video. Its first product is Butterfly Story Factory, a local Windows studio.
Is Butterfly Engine available now?
The documentary core and production-preparation layers are completed and validated. Butterfly Story Factory is available as a Developer Edition. Later roadmap layers — autonomous media and cloud rendering — are still in development.
Is it cloud-based?
Butterfly is local-first. Story Factory runs on your Windows PC and writes videos to your own disk. Only the prompts and text needed for an AI request are sent to the providers you enable.
Which languages are supported?
Story Factory supports 24 narration and subtitle languages, including English, Turkish, Spanish, German, French, Portuguese, Arabic, Hindi, Japanese, Korean and Chinese. The interface is available in 14 languages, and custom BCP-47 tags are accepted.
Can I use the videos commercially?
Yes. The Developer Edition license allows you to monetize the videos you create. You remain responsible for factual accuracy, third-party rights and each platform's policies.
How is this different from a text-to-video model?
A text-to-video model generates a clip. Butterfly Engine orchestrates a documentary: research, narrative structure, scene planning, visual prompts, asset manifests, narration, subtitles, timeline and final render. The output is a reproducible production, not an isolated generation.
08 / About
Built independently.
Butterfly Engine is independently developed by Kadir Sel. It is not a wrapper around a single model; it is a production system designed around how documentaries are actually made.
The project began with a simple conviction: ideas should not stop at text. They should become structured stories, visual concepts and production-ready media — without losing the reasoning that connects them.

Seat = one named person using the studio on one Windows machine. Seats are license terms, not device-locked DRM. Source code is included in every tier.
BUILT TO SELL
Make the studio pay for itself.
The commercial license lets you produce videos for your channel, your clients or your agency. You keep the revenue — there is no per-video fee.
One topic becomes a scripted, narrated, subtitled video.
Publish it or hand it to a client.
Your only variable cost is your own API usage.
Average estimate: a 30-second Short uses about $1.32 in API credit on Standard (Essential $0.82, Premium $2.63); a 5-minute horizontal film averages about $2.35. Actual OpenRouter billing may be lower or higher; agencies charge $150–500 per finished short.
