AI you can trust
with the work that matters.

Wynfall Studios builds Wynfall AI, a family of models for writing, decisions and code. We make it for people and companies whose work is private by nature: the unreleased product, the unpublished draft, the client file.

Why we exist.

If your work is not yours to share, getting help should not mean breaking a promise to someone else. So we built our company around one rule: nothing you give it trains a model, unless you send it to us as feedback.

We run our own model family on infrastructure we choose, so that we can keep that rule.

What we promise.

No training, unless you send feedback.

Nothing you give it trains a model, on any plan or trial, unless you send it to us as feedback. That rule is in our Terms, not a setting you have to find.

Plain limits, no surprise bills.

Every plan states its room and its limits in numbers. No automatic overage charges are planned, and when a paid plan runs out of usage, Sigel waits until it refills.

Your data, your call.

Ask what we hold about you, or ask us to delete it, by writing to hello@wynfall.dev. A person answers.

We say what exists.

No invented customers or borrowed benchmarks. When something is planned we call it planned, and every change gets a dated entry on our updates page.

Read the exact wording in our Terms

One model, one rule.

Every model and tool follows the same privacy rule. Meet Sigel, or read how Wynfall is different.

The short version, in plain words.

What is Wynfall AI?

Wynfall AI is a private AI assistant for writing, decisions and code, running on Wynfall’s own models. You can use it in chat in your browser, in Wynfall Desktop for Windows, or in Wynfall Code in your terminal. It is open to everyone: sign up with an email code or a passkey, and every new account starts with 3 days of Builder, free and with no card.

How Wynfall is different
Who makes Wynfall AI?

About Wynfall Studios
Does Wynfall AI train on my work?

No. Nothing you give it trains a model, on any plan or trial, unless you send it to us as feedback. The rule is written into our Terms.

What is Sigel?

Sigel is the Wynfall model. Wynfall Sigel reasons more deeply for code, writing and long documents, and it holds very long conversations, with room for hundreds of pages on every plan. It is on every plan.

Meet Sigel
Is it free to try?

Yes. Every new account starts with 3 days of Builder, free and with no card: Sigel with Max thinking, in your browser, in Wynfall Desktop and in Wynfall Code. When the trial ends you choose a plan to keep going, and Starter is $10 a month. Every limit is on the pricing page.

Where are my chats stored?

In the web app, your chats are kept in your browser, encrypted with a key that never leaves it. They are not stored on Wynfall’s servers, and they do not follow you to other devices yet. To answer, Sigel reads each message on our servers.

Privacy, in plain words
Can I delete or export my data?

You can download a backup of the chats in your browser and delete them from Settings. To delete your account and the records we hold, or to ask what we hold and for a copy, write to hello@wynfall.dev. We answer within 30 days.

Deleting and exporting
How long do you keep my data?

Account records stay while your account is open and for a reasonable period afterwards. We do not promise a fixed deletion period we cannot verify, and you can ask us to delete yours at any time.

The Privacy notice
What does it run on?

Chat works in a modern browser. Wynfall Desktop is for Windows. Wynfall Code runs in the terminal on Windows, macOS and Linux.

Downloads
Does it work offline?

Sigel runs on our servers, so it needs a connection. Wynfall Desktop can also run a model on your own computer, which does not.

Run a model on your computer
Is there a plan for teams?

Teams is coming soon, with no price or date yet.

About Teams
Is there an API?

The API is a separate offering, priced by model. Rates are published before it opens. Consumer plans do not include API credit.

API pricing
How do you keep my account secure?

You sign in with an emailed code or a passkey. The Trust and security page says how your work is handled and how to report a problem.
