Code, with the diff beside it.
Open a folder and the model reads files, runs your tests and makes the edit, inside the permissions you set. The Changes panel shows exactly what changed.

If you have used other AI assistants, most of it will feel familiar: ask, draft, plan, fix. Four things work differently here.
How Wynfall is different, in fullNo training on your work.
Nothing you give it trains a model, on any plan, Free included, unless you send it to us as feedback. It is a rule in our Terms, not a setting to find.
Read our TermsLimits you can count.
Free is about 6 messages a day. Every paid plan states its usage in messages and hours of coding, and no automatic overage charges are planned. Every number is on the pricing page.
See every limitClear when you run out.
When a paid plan runs out of room, Sigel waits until your room refills, or you move up a plan. No automatic overage charges.
What happens if I run outOur own model, in three places.
Sigel is the Wynfall model. Use it in chat in your browser, in Wynfall Desktop for Windows, or in Wynfall Code in your terminal.

What happens to your words.
Most assistants ask you to trust a setting. Ours is a rule, and the path is short enough to read in one breath.
You write.
A draft, a decision, a file from your project.
Your browser keeps it.
In the web app, chats are kept in your browser, encrypted with a key that never leaves it.
The model answers.
Sigel reads your message on our servers and replies. That is the whole job.
It stops there.
Nothing you give it trains a model, on any plan, Free included, unless you send it to us as feedback.
The no-training rule is written into our Terms, not tucked behind a toggle.
Read the exact wordingSigel. One rule.
Sigel keeps your work out of training. It is the one model at launch, on every plan, shown by three feathers: the same mark you see in the apps.
