Out of the box, an AI talks like nobody in particular — eager to please, quick to agree, and just as confident when it's wrong. styleyourai turns it into a voice you choose: warmer or colder, blunt or diplomatic, terse or thorough. Pick a ready-made persona, turn a few dials, and copy the result straight into Claude, ChatGPT, Gemini, or Ollama.
Everything you make lives only in this browser. There is no account and no server to send it to.
No prompt-engineering degree required. If you can move a slider, you can do this.
Start from one of the ready-made personas below — or a blank one — that already fits what you need.
Nudge the voice until it sounds right: warmth, bluntness, humor, how much it explains. Watch it change live.
Copy the prompt into your favorite AI — or talk to the persona right here to feel it first.
A “dial” is just a slider that changes how it talks. Here's what a few look like:
Take one as-is, tweak it to taste, or use it as a starting point for your own. Every one is fully editable.
A well-rounded everyday assistant you can shape per person.
Cut what's dead, keep what's alive — your words, sharper.
Any idea, made to click — no jargon, no talking down.
Stuck? Think out loud. Ideas and momentum, judgment later.
The honest read, no hedging — so you can decide and move.
Finds the holes now, while they're cheap to fix.
Swaps, timing, and a save when it's going sideways.
In your corner, and won't let you off easy.
Put the noise down. One clear next step, no more.
From 'we should go somewhere' to a plan that holds.
A story with warmth and a little wonder.
Working code and the why — no CS degree assumed.
…and a blank canvas whenever you'd rather build from scratch.
Each slider compiles into real instructions — move it and the prompt actually changes, no guessing.
Add a splash of Feynman's clarity or Dorothy Parker's bite. Texture, not caricature.
One click gives you a clean system prompt tuned for Claude, ChatGPT, Gemini, or Ollama.
Try a persona right in the browser with your own API key — change a dial, ask again, feel the difference.
No account, no server, no upload. Everything you make stays in this browser.
It's a web page. Open it, make a persona, copy it out. That's the whole thing.
styleyourai started as a gift for my mom — a way for her to get real help from an AI without learning what a system prompt is, and without the stock voice that flatters first and informs second. A vanilla AI isn't neutral: it's tuned to keep you chatting, to agree with your framing, and to sound sure of itself either way. That's a bad deal for the people we love.
AI can do enormous good when the person using it holds the dials — so here they are. Free, with no account, no tracking, and no server: what you write here can't be collected by anyone, including me. Not freemium. Not a trial. A gift.
Pick a persona, turn a dial, copy the prompt. See what it's like to have an AI that sounds like you meant it.
