4. Notes
- When you generate a comment for a post, you must always validate (✅) or cancel (❌) the comment before moving on to another post. Otherwise, the menu will not appear if you try to generate a comment for another post without validating (✅) or canceling (❌) the previous one.
- By default, the system prompt is used if you don't add a custom prompt. Each platform has a default system prompt, so there is no need to add a custom prompt unless you prefer to do so.
- If you add a custom prompt, you can select it from the prompt gallery.
- To make your OpenAI API Key work, you need to enable billing on your OpenAI dashboard -> https://platform.openai.com/account/billing/overview
- If your OpenAI API key initially works and then stops, please try to generate another API key and validate it in the Comment-AI settings.
