-## Arbitrary Prompts
-
-What if you want to take AI on the journey of test automation and ask it questions while browsing pages?
-
-This is possible with the new `AI` helper. Enable it in your config file in `helpers` section:
-
-```js
-// inside codecept.conf
-helpers: {
-  // Playwright, Puppeteer, or WebDrver helper should be enabled too
-  Playwright: {
-  },
-
-  AI: {}
-}
-```
-
-AI helper will be automatically attached to Playwright, WebDriver, or another web helper you use. It includes the following methods:
-
-- `askGptOnPage` - sends GPT prompt attaching the HTML of the page. Large pages will be split into chunks, according to `chunkSize` config. You will receive responses for all chunks.
-- `askGptOnPageFragment` - sends GPT prompt attaching the HTML of the specific element. This method is recommended over `askGptOnPage` as you can reduce the amount of data to be processed.
-- `askGptGeneralPrompt` - sends GPT prompt without HTML.
-- `askForPageObject` - creates PageObject for you, explained in next section.
-
-`askGpt` methods won't remove non-interactive elements, so it is recommended to manually control the size of the sent HTML.
-
-Here are some good use cases for this helper:
-
-- get page summaries
-- inside pause mode navigate through your application and ask to document pages
-- etc...
-
-```js
-// use it inside test or inside interactive pause
-// pretend you are technical writer asking for documentation
-const pageDoc = await I.askGptOnPageFragment('Act as technical writer, describe what is this page for', '#container')
-```
-
-As of now, those use cases do not apply to test automation but maybe you can apply them to your testing setup.
-
-## Generate PageObjects
-
-Last but not the least. AI helper can be used to quickly prototype PageObjects on pages browsed within interactive session.
-
-![](/img/ai_page_object.png)
-
-Enable AI helper as explained in previous section and launch shell:
-
-```
-npx codeceptjs shell --ai
-```
-
-Also this is availble from `pause()` if AI helper is enabled,
-
-Ensure that browser is started in window mode, then browse the web pages on your site.
-On a page you want to create PageObject execute `askForPageObject()` command. The only required parameter is the name of a page:
-
-```js
-I.askForPageObject('login')
-```
-
-This command sends request to AI provider should create valid CodeceptJS PageObject.
-Run it few times or switch AI provider if response is not satisfactory to you.
-
-> You can change the style of PageObject and locator preferences by adjusting prompt in a config file
-
-When completed successfully, page object is saved to **output** directory and loaded into the shell as `page` variable so locators and methods can be checked on the fly.
-
-If page object has `signInButton` locator you can quickly check it by typing:
-
-```js
-I.click(page.signInButton)
-```
-
-If page object has `clickForgotPassword` method you can execute it as:
-
-```js
-=> page.clickForgotPassword()
-```
-
-Here is an example of a session:
-
-```shell
-Page object for login is saved to .../output/loginPage-1718579784751.js
-Page object registered for this session as `page` variable
-Use `=>page.methodName()` in shell to run methods of page object
-Use `click(page.locatorName)` to check locators of page object
-
- I.=>page.clickSignUp()
- I.click(page.signUpLink)
- I.=> page.enterPassword('asdasd')
- I.=> page.clickSignIn()
-```
-
-You can improve prompt by passing custom request as a second parameter:
-
-```js
-I.askForPageObject('login', 'implement signIn(username, password) method')
-```
-
-To generate page object for the part of a page, pass in root locator as third parameter.
-
-```js
-I.askForPageObject('login', '', '#auth')
-```
-
-In this case, all generated locators, will use `#auth` as their root element.
-
-Don't aim for perfect PageObjects but find a good enough one, which you can use for writing your tests.
-All created page objects are considered temporary, that's why saved to `output` directory.
-
-Rename created PageObject to remove timestamp and move it from `output` to `pages` folder and include it into codecept.conf file:
-
-```js
-  include: {
-    loginPage: "./pages/loginPage.js",
-    // ...
-```
