How Wynfall
is different.
Wynfall AI is a private AI assistant for writing, decisions and code, made by Wynfall Studios, LLC. Five things set it apart, each explained below with a link to the exact wording.
Open to everyone Every plan and limit is on the pricing page
No training on your work.
On every plan.
Nothing you give it trains a model, on any plan or trial, unless you send it to us as feedback. It is a rule written into our Terms, not a setting you have to find. In the web app, your chats are kept in your browser, encrypted with a key that never leaves it. They are not stored on our servers, and the models read each message on our servers only to answer it.

Every plan says how much room it gives next to Starter. No automatic overage charges are planned, and when your room runs out, Sigel pauses until it refills.
- Starter $10 a month
- Room for everyday use. Longer documents. Sigel, with Wynfall Code and Max thinking.
- Builder $20 a month
- About 3× Starter. Long documents and big files. Sigel, with Wynfall Code and Max thinking.
