How it works

Three steps. Sixty seconds.

01

Say who you are

Name, role, and exactly the details you want — every social (LinkedIn, GitHub, X, YouTube, Instagram, portfolio…), phone, company, email. All optional, all yours to toggle. Photo and logo too, on Pro.

show: LinkedIn ✓ GitHub ✓ phone ✗ email ✓ — you choose
02

Describe your vibe

One sentence. The AI picks the motion, draws the palette, sets the type — designed for you, not pulled off a template shelf.

"terminal hacker energy, tasteful" · "champagne gold, calm luxury"
03

Copy. Paste. Done.

One click installs it in Gmail, Outlook, or Apple Mail. We host the animation so it never breaks — dark mode included. Change anything later by just asking.

⌘C → Gmail Settings → ⌘V · that's the whole install
Nine vibes, nine designs

One sentence in. This out.

Every card below started as the little quoted prompt on it. No templates were harmed — each one is designed from the words.

FAQ

The things everyone asks.

Does it really work in Gmail and Outlook?

Yes — that's the hard part we obsess over. The signature is email-safe HTML with the animation as a hosted GIF, the one format every major client renders. Tested in real inboxes: Gmail web & app, Outlook, Apple Mail, dark mode included.

Will it hurt my email deliverability?

No. Clean standard HTML, no scripts, no tracking pixels. It's the same technique corporate signature tools have used for years — ours just looks better.

What if I want to change something?

Tell it in plain words — "more teal", "bigger name", "calmer motion" — and the AI redesigns in seconds. Pro keeps your signature editable for two full years.

Why is the animation hosted by you?

Email clients load images from a URL. We host yours on a fast CDN so it never breaks, loads instantly, and updates everywhere when you edit it. Pro includes the files too, so you always own your signature.
