October 15, 2026Release

Early access is open for signup. We let people in by hand, in waves.

Wynfall AI is in early access. Anyone can sign up at chat.wynfall.dev with an email code or a passkey, and no card is needed. While internal testing finishes, the team lets people in by hand, in waves, so not everyone who signs up will be let in this week.

Once you are let in, you get 7 days of Builder: Ken, Sigel, extended thinking and Wynfall Code. The 7 days start when you are let in, not when you sign up. When they end, the account moves to Free on its own. Nothing is charged, and you keep Ken every day.

Wynfall Desktop for Windows and Wynfall Code for your terminal are on the download page for accounts that have been let in. Both sign in with the same account.

Starter, Builder and Studio add Sigel, thinking and Wynfall Code; paid plans open soon, and we will announce it here first. Teams is coming soon.

The rule has not changed. Nothing you give it trains a model, on any plan, Free included, unless you send it to us as feedback. Nova is coming later, with no date.

Every update is on the updates page and in the RSS feed.
