Wyrdspinner
Spin a world. Live the story.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Every choice spins out the wyrd web of your story.
Wyrdspinner is an AI-powered text adventure engine in which you build a living world, with a story companion of your choice. There's no fixed plot. The narrator listens, watches what you do, and responds to your choices. No two stories will be the same. This isn't a game, there's no levels, it's interactive fiction. This is a never-ending story, your story.
Pick from procedurally generated campaigns — fantasy, sci-fi, mystery, slice-of-life — or build your own world from scratch. Choose an art style for rendered scenes. Session Zero walks you through your Guide, your character, the tone, and the stakes. At each story beat you can pick from 3 pre-generated paths, or get creative and take control by writing your own entry into the story. If you think a described scene sounds cool and you want to see it...you can, by hitting the View Scene button. You can export your story whenever you choose, it's yours.
I built this app for myself to use, then realized other people might want to use it too, so I tried to make it something as accessible as possible. I've never built an app before...I hope you like it.
A purchase IS required to enjoy the app, there is no free trial. Ongoing AI storytelling runs on tokens unless you. The starter bundle gets you going, after that you can use your own Gemini key to keep the story going, if you want. I tried to make the monetization fair, LLMs aren't free to tap into.
• Gemini used for rich interactive narrative
• Nano Banana image generation ("View Scene")
• Theme-shop to spice up your reading experience.
WORLDS THAT EVOLVE
Your decisions ripple. A revolution you started in chapter one is still rumbling under the surface in chapter twelve. The world feels lived-in because it is. You can drive the story, or you can ride along where it leads.
SEE IT
In your mind's eye, or with the ones on your face. Nano Banana is in the current build, with new models being added over time. The plan is to add new art styles over time, as I figure out what people are wanting to see there.
A LOOK THAT FITS THE TALE
A library of hand-crafted themes, each with their own scalable curated font - warm Parchment for fantasy, dragonscale for Dark Lord, neon synthwave for Cyberpunk, soft Kawaii bubbles for cozy adventures, plus a plain reader theme and a high-contrast accessibility theme. Switch any time. More themes will come to the theme shop in time.
THREE DIALS
Not every decision you make is a win. The possibility of failure is baked in, making your story more dynamic. You can dial Difficulty up or down to customize how often you're having to pivot from a negative outcome.
INTENSE AS YOU WANT - Candlelit, Torchlit, Bonfire, or Inferno. Dial it up to raise the stakes; down for a gentler read.
ROLL THE DICE - When appropriate the narrator will roll dice. A failure means a negative outcome. Can you pivot the story back into your favor? DIFFICULTY level determines failure rate.
VERBOSITY - Shapes the prose — Terse, Standard, or Verbose. Match it to your appetite for prose.
READING LEVEL - Depending on how this app does, I may release additional versions tailored for different age groups. Every effort was taken to keep stories appropriate for users 13 and up.
ACCESSIBILITY
Built screen-reader-first with proper ARIA labels, focus management, a high-contrast theme, and reduced-motion support. Skip-to-story link, Escape-key dialog dismissal, and a Plain Reader theme that strips visual flourish.

Ratings & Reviews
Playing with your own Gemini key works again. Google retired the model the app was requesting, so own-key story turns had stopped; the app now uses Gemini 3.5 Flash-Lite.
Theme cards preview each theme's real typeface again, and tapping a theme you don't own now opens the purchase dialog instead of appearing to do nothing.
"Begin Story" no longer appears twice at the end of Session Zero.
Returning players can now find sign-in from the title screen, and restoring with nothing to restore offers to sign you in rather than failing.
The subscription shop defaults to monthly and shows annual plans as a per-month price. Assorted layout fixes on light themes.
