Insights AI and Insights AI Lite analyse your calls in the same place in CX-Engine. The main difference is who produces the transcript: CX-Engine, or your 3CX phone system.

- **Managed by CX-Engine**: CX-Engine produces the result with its own AI.
- **Managed by PBX**: your 3CX produces the result with its configured AI provider, and CX-Engine retrieves it.
- ✓ / ✗: the feature is available, or not, on this plan.

## Which Plan Should You Choose?

**Choose Insights AI if** you need speech KPIs, sentiment evolution, obfuscation or the correction of your custom vocabulary, or if you don't use 3CX V20.

**Choose Insights AI Lite if** your 3CX already transcribes your calls with its AI provider, and you want CX-Engine to add the detailed analysis and audit grids.

You can use both on the same account, by choosing the plan for each extension in **CRM Connector** > **Settings**. See our [Pricing](/en/pricing) page for more information.
