# fill

Fill an input field using a CSS selector, an AI prompt, or both. Supports TOTP code injection for 2FA fields.

<CodeGroup>
  ```python Python theme={null}
  # Standard Playwright fill
  await page.fill("#email", value="user@example.com")

  # AI-powered fill
  await page.fill(prompt="Fill 'user@example.com' in the email field")

  # Selector with AI fallback
  await page.fill("#email", value="user@example.com",
      prompt="Fill the email address field")
  ```

  ```typescript TypeScript theme={null}
  // Standard Playwright fill
  await page.fill("#email", "user@example.com");

  // AI-powered fill
  await page.fill({ prompt: "Fill 'user@example.com' in the email field" });

  // Selector with AI fallback
  await page.fill("#email", "user@example.com", {
    prompt: "Fill the email address field",
  });

| `selector`                           | `str` / `string` | No       | CSS selector for the input field.                                                                            |
| `value`                              | `str` / `string` | No       | The text value to fill into the field.                                                                       |

| `ai`                                 | `str` / `string` | No       | Controls AI behavior. `"fallback"` (default) tries the selector first, then AI. `None` / `null` disables AI. |
| `totp_identifier` / `totpIdentifier` | `str` / `string` | No       | Identifier for a stored TOTP secret to generate a one-time code.                                             |
| `totp_url` / `totpUrl`               | `str` / `string` | No       | TOTP provisioning URL (`otpauth://...`) to generate a one-time code on the fly.                              |
| `**kwargs`                           |                  | No       | Standard Playwright fill options (e.g., `timeout`, `force`).                                                 |

Returns `str` / `string` -- the resolved selector used.
