An AI film shot in relay by all of its participants
GPT-6 Astra serves as the AI director, and Google Veo 3.1 generates the picture and sound. The whole site shows a single film: together, participants are turning Vitalik Buterin's 32-chapter science fiction novel Snowmoon, starting from its very first sentence, into one continuously growing feature film, segment by segment.
Each segment lasts 8 seconds and is owned by one paying participant. The system first writes a draft from the novel, and the owner can adjust its details. Filming starts as soon as the segment is approved, and the segment is permanently credited to its owner. The main plot follows the novel strictly; the details are decided together by the participants.
The author explicitly invites adaptations
On the novel's own page, Vitalik states clearly that Snowmoon is released under GPL v3. As he explains there, people are free to turn it into a film, an AI animation, or any other kind of work.
His note also comes with one important principle: the AI prompts, scripts, custom pipelines and other non-generic materials used in production should be made open, so that others can keep building on the work. SNOWMOON's relay model follows exactly this spirit: participants don't just watch the adaptation, they take part in making it.
Read Vitalik's novel and license statement →Segment by segment, into one feature film
· The film is made up of segments lasting 8 seconds, with picture, sound, and dialogue handled according to the source text's meaning.
· Each segment starts only after the previous one is finished, and it begins from the previous segment's final frame so characters, setting and movement stay continuous. A segment takes about 2–3 minutes to film.
· The story begins with the first sentence of Chapter 1 and follows the novel's order strictly. Each segment covers only a short passage, with nothing skipped and no details left out.
· Scene changes happen only when the novel explicitly moves to a new place or time. Otherwise, the characters' positions, actions, clothing, props, lighting and ambient sound all carry over from the previous segment.
How to take part
1. Pay 5 USDC (Ethereum mainnet). Once your wallet is connected, the payment is detected automatically and you receive 1 segment credit.
2. Read the draft and write your ideas first: the director team has already drafted the next segment from the novel, and you can write the details you want to change before paying.
3. Claim the next segment: once payment arrives, claim the segment that is currently open. Each segment has exactly one owner, and the next one opens after it is filmed.
4. Review and filming: GPT-6 Astra reviews your edit. Filming starts as soon as it is approved, and the clip is ready in about 2–3 minutes.
The one thing that cannot change is the novel itself
Details can change; the main plot cannot. Major events, the characters' fates, locations and scenes all follow the novel.
Every edit you make is reviewed line by line against the novel by the AI director, GPT-6 Astra. It has read all 32 chapters and remembers what every character has been through, and it only weaves details that fit the main plot into the segment. Anything that departs from the novel is rejected; you can revise and resubmit, and your credit is not used up.
If you do not submit within the five-minute editing window, the segment is approved from the director's draft, filmed, and still credited to you. If filming fails, the story does not advance and your credit is refunded.
In other words, people drive the picture and the novel guards the story. When more than 3,200 relay segments are complete, every scene of the finished film will be built on the novel's framework while carrying the personal touch of each participant. That is the film SNOWMOON sets out to make.
Free to join
· Watch the film: anyone can watch it for free from segment 1 onward and scrub freely with the progress bar.
· Story log: whenever a segment is finished, its story text appears in the left-hand column.
· Read the novel: the full text of all 32 chapters of Snowmoon is available on this site for comparison at any time.
· Check the engine log: the director's reasoning at every step and the characters' memories are all public.
Every segment an owner films becomes a permanent part of this film. When all 32 chapters are filmed, it will be a feature film grown from the novel and completed by everyone who took part.
