What’s inside

Proven ideas, in your words.

The frameworks and perspectives are our own applications, linked to the original sources. They help you think; the words and the voice stay yours.

Hi! I guard your argument.

About the name

Hi, I’m Sigge.

Sigge is an old Swedish nickname for Sigurd, Sigvard and Sigfrid. The first part, sig-, comes from Old Norse sigr, meaning victory. Sigvard is usually read as something like ‘guardian of victory’.

That suits us. Sigge doesn’t write for you — he watches over your argument. He makes sure your AI has the facts, the reader and a clear framework, so the copy wins on its own merits and still sounds like you.

And yes, Sigge is also a small ink blot with a pencil behind his ear. He turns up when you need him and stays out of the way while you write.

Your brief. Your work.

Sigge helps you choose perspectives and prepare a writing prompt. Your brief, voice samples and draft are processed in your browser. The public workshop does not call an AI service.

When you paste the prompt into an AI chat, that service’s terms apply.

If you choose local saving, your work stays in this browser until you delete it. On a shared computer, another user may see it. Your account is used for email sign-in and AI connections. Sigge uses no analytics or advertising tracking of its own.
