Toonflow

What is Toonflow?

Toonflow is a free, open-source AI developed by HBAI Ltd.Short-Form Drama CreationA tool licensed under the AGPL-3.0 agreement. It positions itself as a “fully automated short-form drama production studio,” with its core capability being the one-stop generation of content from novel text to screenplay, storyboards, and finally video.

core positioning“With just a few taps, turn a novel into a TV series in seconds”—this isn’t just a simple text-to-video tool, but a complete industrialized pipeline that transforms text into finished content. Through multi-agent collaboration (ScriptAgent + ProductionAgent), it automates the entire film and television production process—including screenwriting, storyboarding, voice acting, and video compositing—compressing the production of a short series, which traditionally takes weeks, into just a few hours, while reducing costs by over 90%.

Technology Stack:Electron (desktop) + Vue 3 + Node.js backend + local SQLite database + Docker support.

Key Features of Toonflow

• AI Screenwriter:Supports long-form text input of up to 50,000 characters, automatically breaks down plot structures, and generates scene-by-scene scripts; supports both "Narration Mode" and "Story Mode," and includes built-in templates for popular genres;
• Character Consistency Management:Automatically extracts character appearance, personality, and background details to generate fixed character profiles, fundamentally resolving the ”face-swapping” issue in AI-generated content; supports custom character locking;
• Infinite Canvas Storyboard:Organize scripts, characters, storyboards, assets, and video clips in a near-infinite canvas format, supporting free-form editing, revision, and parallel production without being constrained by linear workflows;
• Multi-model API integration:Supports integration with mainstream models such as Doubao, Qwen-Max, Claude, DeepSeek, Sora, Stable Diffusion, Wan 2.1, and Flux; significantly reduces API costs (by 40%+ or more) through the 32AI intermediary platform;
• Smart Voiceover and Soundtrack:Features a built-in library of over 300 sounds, with automatic matching of background music and transition effects;
• Video Composition and Export:One-click video stitching, supporting platform-specific formats such as 9:16 portrait orientation;
• Cross-session memory system:Based on local ONNX vector retrieval, it supports short-term messages, long-term summaries, and semantic recall to ensure continuity across multiple rounds of generation;
• Run locally in private mode:Supports Windows, Linux, and macOS desktops, Docker deployments, and cloud deployments; data can be fully localized;
• TypeScript Hot Reloading:You can write supplier logic directly in the Settings Center, and it takes effect immediately without the need to modify the source code or restart the system.

Use Cases for Toonflow

• Short-form video content creation:Quickly generate scripts → storyboards → videos, significantly boosting production efficiency;
• Experiments in Adapting Novels for Film and Television:Low-cost visual validation of online literature IPs is a hundred times better than a ”raw draft”;
• MCN / Film and Television Studio:Mass-produce short-form video content with marginal costs approaching zero; use AI-generated prototypes to validate creative concepts before full-scale production and present them to investors;
• Individual Creator / Twitter Handle:A production line for a 100-episode serialized short drama—one person can handle it all;
• Complex physical movements:With 3D/2.5D character modeling and automatic skeleton binding, it offers significant advantages in highly dynamic scenes such as combat and dance sequences.

1. Toonflow does not include built-in AI modelsYou must configure an external API (we recommend using 32AI as an intermediary to reduce costs)
2. Post-production, color grading, and audio-visual synchronization still require professional expertise, accounting for 25–35% of the total budget; cutting this portion will result in nothing more than a ”rough cut.”
3. What really sets people apart isn't the tools; it'sAesthetic Judgment + AI Proficiency—While the tool can generate 100 storyboard frames, it still requires human judgment to determine which one best conveys the emotion.
