TaleStitch

TaleStitch turns a plot and genre into a first chapter and a painted cover, then lets friends add the next chapters one at a time. It is a social storytelling app for people who like writing together and sharing stories with readers.

You describe a scene, a character or a what-if, pick a genre and cover style, and the app writes the opening chapter with you. Each story gets two painted covers, and you can regenerate them until one matches the book you imagine.

Stories can be published with a swipe, readers can like and comment, and audio narration lets people listen instead of read. Daily streaks encourage reading or writing a little each day. The site says the app is free on Android.
