AI for social media posts and replies
Free prompts that cut one idea into a thread, a post, and a caption, answer messages in your own voice, and write Reddit replies that are actually useful.
Social posts written by AI sound like AI because they add things you did not mean: urgency, emoji, a fake question. These prompts work from your idea or your samples and leave that out.
