Show HN: Fine-tuned Qwen2.5-7B on 100 films for probabilistic story graphs
AI plot machine goes full multiverse; writers want an END button and say in the story
TLDR: CineGraphs uses an AI trained on 100 films to map branching plotlines for screenwriters. The community loves the concept but demands dataset transparency, a tutorial, manual editing, and—most loudly—an option to end stories instead of infinite branches
An AI for screenwriters just dropped: CineGraphs, a model trained on 100 films that spins out branching plotlines and exports to the industry’s lightweight Fountain format, ready for Final Draft and friends. The crowd loved the demo’s “authentic” dialogue, but asked for receipts: mmarvin wants the exact movie list used to train it, while hasbot begged for a “how to start” guide and the option to inject their own ideas when none of the branches hit.
Then the drama: 999900000999 discovered stories never end—the tool keeps sprouting branches like a multiverse tree. Cue memes about “Schrödinger’s screenplay,” with readers demanding a big END button. ArchieScrivener pushed for deep control (edit nodes, add branches) and floated using the graphs to grade scripts, which sparked side‑eye about robots judging writers. Another hiccup: riidom saw overlapping nodes in the free version, turning the map into a spaghetti maze.
Despite the chaos, the vibe is excited, really. People want wild twists, but also transparency, a starter prompt cheat‑sheet, and manual steering. The devs pitched “start free with 3 projects,” and the community basically replied: cool—but give us an off‑switch, let us remix the branches, and show us the films behind the curtain
Key Points
- •CineGraphs is an AI-assisted tool for screenwriters that understands narrative structure.
- •It generates multiple narrative branches from any story beat while maintaining consistency.
- •Fine-tuned models provide suggestions aligned with screenplay structure, dialogue, and conventions.
- •Users follow a three-step workflow: start with an idea, explore branches, and sculpt the screenplay.
- •Work can be exported to Fountain format, compatible with Final Draft, Highland, and WriterSolo; a free tier offers three projects.
