WebspinnerFX v1.0 — AI-Native Rendering

The Web,
Re-Rendered by
Intelligence.

Cognitive content doesn't just display. It thinks, adapts, and renders itself. WebspinnerFX delivers cinema-quality procedural animation through a conversational interface — no Houdini expertise required.

Cognitive Content

Content that doesn't just render — it learns from every frame.

WebspinnerFX is the first AI-native desktop application to deliver cinema-quality procedural animation through conversation. Describe what you want. Watch it render. The system gets measurably better with every job.

Every render job, every verification failure, every customer signal feeds a local knowledge corpus. First-pass render success improves over time. Parameter recommendations sharpen with each approval. This isn't a feature — it's the architecture.

Core Capabilities

Intelligence at
every layer.

01

Conversational FX Creation

Describe any effect in plain language. Claude extracts precise Houdini parameters automatically. Review, approve, render. No node graphs, no technical knowledge required.

Parameter Extraction Claude API Hagrid Governance
02

Six Production HDA Templates

A curated library of battle-tested Houdini Digital Assets. Smoke plume, ember cascade, particle field, shatter, logo reveal, ink dissolve — each optimised for Karma XPU rendering.

Houdini Engine Karma XPU EXR → MP4/WebM/ProRes
03

AI-Native Learning Corpus

Every render outcome, every parameter approval, every correction feeds a local SQLite corpus. The system improves its recommendations with every session — this is cognitive content.

AI Rendering Environment

The Environment

Rendered entirely
on your machine.

v1.0 is a standalone macOS application. No cloud subscription beyond Houdini Indie and an Anthropic API key. No network connection during rendering. Your creative process stays entirely under your control.

  • Headless, autonomous render pipeline — no interactive sessions required
  • Self-bootstrapping installation with integrated healthcheck
  • Full event capture from day one, seeding the v2.0 semantic corpus
  • WebM / MP4 / ProRes output with alpha channel support
  • Weaver character animation with Geometry Nodes particle effects

The Architecture

Built to learn.
Designed to compound.

The competitive moat isn't the software — it's the corpus. Every render job creates a training example. The HDA library and accumulated knowledge are proprietary assets that compound with every use. Competitors cannot replicate them after the fact.

v1.0 — Standalone
Runs entirely on your machine. SQLite corpus, local inference, zero server dependency.
v2.0 — SaaS Layer
FastAPI, sqlite-vec, QLoRA fine-tuning, GridMarkets cloud rendering. All v1.0 data migrates forward.
Governance
Hagrid governance — every AI output reviewed before render execution. correction_flag creates QLoRA data.
Licensing
Houdini Indie ($299/yr). User renders on own machine. EULA §3.6 SaaS restriction does not apply.
One step. One test. One commit.

Technology Stack

Minimal by design.
Powerful by architecture.
