A retrain compiles a new Brain draft. It reads your past imports, your team’s review work, and, if you allow it, your live conversations. It produces a draft next to the version you run today. Nothing changes for customers until you review and publish the new draft. Open it from Retrain in the Brain header, or go to /brain/retrain. Retraining is limited to owners and admins.
The retrain form

The retrain form: sources, depth, and goals.

When to retrain

Retrain when the source material changed, not when a single answer is wrong. Retrain when:
  • your team reviewed a few weeks of live conversations, and the corrections should become part of the Brain;
  • you changed a product, a package or a process, and you have real conversations that show the new one;
  • you uploaded a newer chat export;
  • Kai keeps missing a question your customers now ask often.
Do not retrain when:
  • one answer is wrong. Edit it in the review queue, and publish a new draft.
  • a price is wrong. Change the fact. Read Current information.

What Kai learns from

What Kai learns from

The source list, with a live count next to each source.

Selected sources are merged into one corpus, personal data is replaced with placeholders, and everything is compiled together.

The rule that protects the Brain

Kai never learns from its own unreviewed output. A reply Kai sent enters the training corpus only when a person acted on it:
  • a reviewer marked it Good output, or
  • a reviewer wrote a Corrected reply, and then the reviewer’s words replace what Kai actually sent.
An AI reply nobody rated is dropped. Internal notes are dropped. A conversation marked Needs follow-up is excluded completely, including the customer’s own messages, because the outcome of that conversation is not yet known. What customers wrote, and what your team wrote, is always usable. Only Kai’s own words need a human decision first.
This is why turning on All live conversations is safe. Kai reads the customer side and the human side of every thread, and still ignores its own unvetted replies.

How deep to go

Deeper runs cost more and take longer. The cost sits in one place: reading a conversation for the first time. Light and Standard reuse what Kai already understood about a conversation, so a retrain over a mostly unchanged history is cheap. Deep ignores that and reads every conversation again, so it costs one reading call for every conversation in the corpus. Deep also lowers the threshold at which a pattern is kept, so rare questions reach the Answer Library. That is what you want after a product change, and it is not what you want as a monthly habit.
Start with Standard. Choose Deep only when you changed something fundamental, or when Kai keeps missing a question you can see in the history.

Goals

Goals are optional. They steer emphasis and phrasing. You can select a template, for example Shorter replies, Careful with numbers, Escalate sooner, or write your own. A goal is steering, never a fact. A goal cannot add information your team never wrote. If you write “our price is 30.000 TL” as a goal, Kai does not learn a price from it. The Answer Library stays grounded in what your staff actually said, and a price belongs in Current information. Good goals describe behaviour: “End replies with a question or a clear next step.” “Address price objections with answers the team has already given.”

Run it

1

Choose the sources

Leave Past imports on. A retrain that drops the original history builds a Brain from a few dozen live threads and calls it an upgrade.
2

Choose the depth and the goals

Standard, unless you have a reason.
3

Start the retrain

Kai states what happens before it starts: a new draft is compiled, it takes a few minutes, and the version you run today keeps serving customers.
4

Watch it, or close the tab

The progress view shows the percentage, the stage, and the counts. Nothing breaks if you leave.

Review the draft

When the run finishes, select Review the draft. The new draft opens in the review queue.

What happens to your review decisions

A retrain rebuilds every entry from scratch, so the identifiers change. Kai carries your decisions across by content, not by identifier. The rules are deliberately careful.
An approval must never sit on text nobody approved. This is why an approved entry whose wording changed comes back to the queue. Expect some re-review after every retrain, and expect more of it after a Deep run.
After the run, Kai states that approvals and edits carried over wherever the content is unchanged.

Nothing changes until you publish

The retrain creates a draft. Your published version keeps answering customers the whole time, during the run and after it. To take the new draft live, work the queue and select Publish. Read Review and publish.
