## How to use Symmetry Tax Logic Chat

With the Symmetry Tax Logic Chat add-on, all users within your company who have a Client Support Center login can access it from the homepage (upper right).

To get the most accurate and detailed answer, use a clear and specific prompt:

<Steps>
  <Step title="Attach your log file or JSON payload">
    Attach your log file or [PayCalc session recording](/ste/ai-interfaces/tax-logic-api/paycalc-session-recording) for STE on-premise, or your JSON request for STE API. Symmetry Tax Logic Chat supports `.json`, `.txt`, and `.log` file types. If you don't attach a payload, you'll receive a message asking you to upload one.
  </Step>

  <Step title="Ask a clear question">
    We have found the best results come from using the following format: "Explain step by step how the STE calculated X tax according to the attached log."
  </Step>

  <Step title="Reference the tax">
    Be sure to ask about only one tax at a time and reference the tax in a way that can be associated with the tax ID. You can also just provide the tax ID.
  </Step>

### Log file requirements

## Example prompts
