Free AI Social Media Post Generator for Authors
Generate three post options for X, Instagram, TikTok, LinkedIn and Facebook groups from your book, each written for how that platform reads, and turn any of them into a matching graphic at the right size.
How the social post generator works
Three steps turn one book into a week of posts that each sound native to the platform they run on.
Describe the book
Give the title, the genre, and a short description. Attach a book from your library and the generator reads the real blurb, keywords and chapters instead of guessing.
Pick your platforms
Choose the channels you actually post on. Each one costs 20 credits and comes back with three complete options on three different angles: a thread for X, a caption and hashtags for Instagram, spoken beats for TikTok, a professional angle for LinkedIn.
Add a graphic and schedule
Copy each post, adjust the details only you know, and schedule them across launch week. Every option arrives with an image prompt already written for it, so one click turns it into a graphic at the exact size that platform wants.
Who uses the social post generator
Writing promotion copy is a different skill from writing books. These authors use the tool to stop staring at an empty compose box.
Authors in launch week
You need several posts a day across channels and no time to write them. Generate the set in one run and spend your energy replying to readers instead.
Writers who dislike self-promotion
Talking about your own book feels awkward. Start from drafts that lead with the story rather than the sale, then soften or sharpen them to sound like you.
Backlist authors
An older title still sells when it stays visible. Generate fresh angles on a book you published years ago and keep it circulating.
