AI Filmmaking got 10x easier with Fable 5 - I Built 3 Free Tools
Utilizing LLM coding capabilities via Claude Fable 5 empowers filmmakers to create bespoke web applications and integrate external APIs via MCP to standardise complex production pipelines.
What this lesson covers
Dan Kieft showcases how filmmakers can use Claude Fable 5 and Claude Code to build custom web tools and automate repetitive AI video production steps. He introduces three free custom web applications designed to streamline script writing, camera angle referencing, and motion prompting.

Connecting custom web applications directly to Higgsfield via MCP and Claude API keys enables streamlined generation without constantly switching platforms.
Workflow outlined in the video
- Identify repetitive production bottlenecks and answer the three-question planning framework: what to build, why, and key features.
- Meta-prompt Claude in standard chat mode to build a comprehensive system prompt for your custom tool.
- Input the master prompt into Claude Code using Fable 5 or Opus 5 to generate your functional web application.
- Generate a Claude API key from the Anthropic platform console and integrate your Higgsfield account via Higgsfield MCP.
- Use the resulting web application to manage script structure, character details, and automated image generations from a unified dashboard.
