Synthemo makes two products. Fluxion puts the best image and video models in one place, with the price on every button. Northline builds personas that hold a real character and tell you plainly what they are. We also build custom digital twins: a real-time voice and video version of you, made from your own interviews and words.
Fluxion makes images and video. Northline makes personas you can talk to. Both start simple and tell you what's under the hood.
Real-time voice and video personas with a character that holds: a voice, a temperament, a way of handling pressure, things it won't do. Ask one what it is and it tells you, in its own voice.
Type a prompt and pick the model you'd pick yourself. Turn a premise into a cast, a storyboard and clips with Story, then cut clips together in Edit: trims, crossfades, fades and AI music from ElevenLabs. When you want control, switch to Node mode and wire the whole pipeline on a canvas.
A digital twin that talks like you, knows your work, and holds a real conversation as you, so your ideas can reach people when you can't.
Every twin has the same voice, face and safety rules. What changes is depth: how much of you it knows.
You can see what made the result and what it cost. Nothing happens off stage.
We name the models we run and who makes them. A persona never pretends to be a person.
One prompt or one conversation to start. Depth is there when you want it, never in the way.
Made with the same models: brand spec films and early persona studies. The brands didn't commission any of it.
Spec films and early studies. None of this is client work; the brands didn't commission it.

Philip builds AI personas and the tools around them, as an agentic engineer: he directs AI agents through the design, code and testing of Northline and Fluxion.
Before this, over a decade of 3D product rendering and animation for Logitech, Nvidia, Apple and Google.
He's also DT01, the first Synthemo twin. Request access if you'd rather ask the twin than read this.
