Synthograsizer is a browser-based creative suite for structured AI prompt engineering — with hardware controller support, live generative sketches, and real-time video streaming to Daydream Scope. Built for artists, VJs, and researchers who think with their hands.
Most AI tools treat prompts like text boxes. Synthograsizer treats them like performable parameters — every variable a knob, every template a patch.
A D-pad interface turns every prompt variable into a navigable parameter. Shape ideas by ear, not by retyping.
Wire physical controllers directly into the creative loop. Every knob, fader, and pad becomes a mapping surface.
From prompt to pixels to projector — text, image, and video models all live one click away in the same canvas.
Synthograsizer is a single, deeply integrated creative environment. Every tool below is available inside the app — no switching tabs, no separate logins.
The instrument. D-pad prompt navigator with MIDI + OSC hardware control, 50+ templates, batch generation, and a live p5.js canvas — all in one browser tab.
Open app →Multi-agent Gemini orchestration with 46+ persona presets, configurable turn-order routing, autonomous turn-taking, structured artifact emission, live token streaming, and a per-turn agentic trace viewer for debugging consensus and tool use.
Gemini image generation, Veo 3 video with batch queuing, Smart Transform, reverse-prompt analysis, and metadata extraction.
Full glitch-art engine embedded directly in the app — destructive pixel effects, non-destructive filter chains, selection tools, and live P5 canvas feed.
In-page generative sketch runner with live variable sync, CSS FX drawer, and External Display output for OBS and Daydream Scope.
Map any MIDI controller to any template variable. Route OSC to TouchDesigner, VDMX, or Max — every parameter is a performable knob.
Lyria RealTime audio generation driven by the current prompt context — ambient scores, generative soundscapes, live to output.
Designed for the way creative work actually happens — iterative, tactile, and never locked into a single pipeline.
Pick from 50+ included templates or import your own JSON. Generative sketches, cinematic prompts, character generators — all share the same variable format.
Connect MIDI hardware or map OSC destinations. Every variable becomes a knob. Save the mapping per template for instant recall.
Send prompts to Gemini for text, image, or Veo video generation. Run a live p5.js sketch alongside. Batch 100 variations, or generate a single curated output.
Push the output to OBS via the Display Window, stream the canvas to Daydream Scope over WebRTC, or route Spout to any visual pipeline.
Agent Studio is a small orchestration runtime — the pieces that make a multi-agent conversation reproducible, inspectable, and steerable.
A configurable policy decides who speaks next — round-robin, mention-driven, or autonomous turn-taking with a stop condition. Per-template overrides keep behaviour predictable.
Each agent's prompt is composed at runtime from a persona, the shared transcript, and any artifacts emitted by prior turns. The same JSON template format defines personas and prompts.
Every turn writes a trace record — inputs, raw model output, parsed artifacts, latency. The trace viewer renders the run for debugging; consensus detection ends the loop when agents converge.
Templates are portable, readable, and designed to be authored by humans or generated by LLMs. A template is a prompt skeleton plus a set of weighted variable lists — optionally with an embedded p5.js sketch for live visual output.
The same JSON drives prompt assembly, batch evaluation runs of up to 100 variations, and agent persona definitions — one schema, three runtimes.
Import from PNG metadata, generate with the Template Generator, or author by hand. Share them, remix them, version them in git.

Built to sit comfortably alongside existing creative software — not replace it.
Open the suite in your browser. No install. No account. Just you, a template, and a canvas.
