# Playground: test a conversation safely

_Library · 2 min read · Updated 2026-10-08 · https://lanachat.ai/guides/playground/_

The Playground lets you chat with a creator as if you were a fan. The AI answers for real, with her persona and AI Brain, but **nothing goes to Telegram**.

## Start a test

1. Open **Playground** under Tools, in the Chatting group of the sidebar.
2. Pick the creator on the left. She needs a linked AI Brain; otherwise the page tells you to link one.
3. Type in **Write as the fan would…** and press Enter (`Shift` + `Enter` for a new line).

From an AI Brain, **Try it** opens this page on a creator linked to that brain; **Testing:** at the top names the brain that answers.

Her replies arrive in bubbles with a typing delay, like on Telegram. Each reply shows how long it took and which step of the conversation she is in.

## Test a sale

When she offers paid media, you see a preview with its price and **Test offer**. Press **Simulate purchase** to see what she does after a payment. No Stars are spent.

## Compare two brains (A/B test)

Turn on **A/B test** to open two panes side by side, each with its own AI Brain. Send to one side, or use **Send to both** to compare the answers to the same message.

## Start over

**Reset** clears the conversation and starts a new test. Nothing changes on Telegram. In A/B mode, your brain choices stay.

> Note: Test conversations are kept in this browser only. A teammate on another computer won't see them.

> Tip: If a reply says "Held by the safety agent", the message would have been blocked for a real fan too. Nothing was sent.
