Reelpen

Reelpen is a browser-based 3D scene builder for AI video, storyboarding and previsualization.

Arrange characters, props and environments. Direct character movement, plan camera shots, and export reference videos and PNG keyframes for your AI video workflow.

Connect a compatible AI assistant through MCP to inspect and edit your allowed scene. This channel shares practical scene-building, camera and connection tutorials.

Free beta: no payment card required. AI assistants and external video generators have separate access rules and charges.
