+## Why use Ovo Talk if I can use ChatGPT directly?
+
+Well, for a couple of reasons:
+
+- Ovo Talk provides unique features such as custom system prompt, AI text-to-speech, voice input...
+
+- Ovo Talk is a convenient way of acessing ChatGPT without Cloudflare.
+
+- The output is generally faster than using OpenAI's website.
+
+- For increased privacy, data submitted on their API [is not used for training](https://twitter.com/sama/status/1631002519311888385).
+
+## It says I have to login?
+
+Correct. To use Ovo Talk, you need a valid OpenAI account, and an API key. Ovo Talk will direct you to the correct place for you to create the API token.
+
+> OpenAI API key usage is billed at a pay-as-you-go rate, separate from your ChatGPT subscription.
