What you need to take note of:

______________________________

1- The API services used for this script, Both the Gemini APIand AssembyAI API have a generous free tier making it possible to use them for free for a while. Depending on usage, you might need to upgrade to a paid tier, reason for which this script was upgraded to Saas making it possible for you to earn by charging users for using the services. 

2- For the Gemini API TTS, Note that you will need billing setup to be able to use the service.

3- This script is sold at a very cheap price despite the good features it offer and as such we will note be accepting refund as the script does not offer any licensing system to limit users from exploiting it once purchased after a refund.

2- Next to to https://aistudio.google.com/app/api-keys and click "Create API Key" Select the project you created earlier and give the API key a name.

3- Copy the generated API key

4- Head back to https://aistudio.google.com/ap... and locate the project and under "Keys" you should now see "1 Keys" click on it and then on the screen that opens, under "Quota tier" click the Setup Billing. this will take you to Google cloud console. 

5- In the cloud console, click the "Link Billing a Account" link and select a billing account. Note that if you have not biling account setup, it will take you to the page to first create a billing account.
