How do I create my own custom prompts?

Open the WriteFastAI settings panel, navigate to “Custom Prompts”, and click “Add New”. Enter a descriptive name, the prompt text (you can use placeholders like {{topic}}), and set default tone/length preferences. Save and the prompt will appear in the quick‑access menu.

Will the extension affect my browser performance?

WriteFastAI is lightweight and only activates when you invoke its UI. Because all AI calls happen via the OpenAI API and results are returned as plain text, the extension has minimal impact on CPU or memory usage.
