The AI writing room for game stories
Build your characters, places and plot with Manta the Scribe — an AI partner that remembers your whole world, and never changes a word without your OK.
With AI, or without it. Rather write every word yourself? Switch AI off and MantaInk is still your world library, your chapters and your drafts — and nothing you write is sent to an AI.
Ask anything about your world. Manta answers from your record and suggests changes — you decide what stays.
Sound familiar?
“It forgot my captain died in chapter two.”
Every character, place and promise lives in one record that Manta checks before it answers.
“It rewrote a scene I loved.”
Manta only ever suggests. Nothing in your story changes until you apply it.
“One new idea broke the whole plot.”
Branch off to chase a what-if. Keep it, or come back to the story you had.
How it works
Pick a fantasy, sci-fi or horror starter, begin from a blank page, or import the manuscript you already have.
Brainstorm, draft and ask questions. Keep the suggestions you like — Manta remembers the rest.
Read it back as prose or comics, publish it to your profile, or hand your team a clear plan to build the game from.
Your work, your rules
Projects are private to you and the people you invite. Sharing a read-only edition is always your choice.
Export your world as a readable story bible, as data, or as a complete backup — whenever you like.
Works with Anthropic, OpenAI, Google and OpenRouter models — or entirely offline on your own machine.
Invite collaborators by username. Every change is credited to whoever made it.
Before you start
Only as much as you want. It can brainstorm, draft scenes and fill in details, but every suggestion waits for your OK.
No. Say so when you sign up, or switch it off any time in your account, and every AI feature steps aside. Your world, chapters, versions and exports work just the same, and nothing you write is sent to an AI.
Manta checks your world’s record before it answers, and MantaInk flags contradictions as they’re written — with a suggested fix you can take or leave.
Yes. Import a manuscript — Word, EPUB, PDF, Markdown or plain text — and it becomes chapters, scenes and characters for you to review.
No. If you can write, you can use MantaInk. The tools for handing a story to a development team are there when you need them.
It’s designed for game stories, and works for any story with a world behind it — novels, comics and tabletop campaigns.
