New here? The whole idea, in three steps.
Start a world
Pick a fantasy, sci-fi or horror starter, begin blank, or bring the manuscript you already have.
Talk to Manta
Ask questions, brainstorm, draft. Drag a character into the chat so Manta knows exactly who you mean — on a phone, type the name.
Keep what you like
Apply the suggestions you want, then Commit to save a version of your world you can always come back to.
Getting started
Your first project, and finding your way around it.
Writing with Manta
Manta the Scribe, its suggestions, and how to be understood.
Your own prompts
Rewrite what each AI feature is told, reuse blocks, and see exactly what is sent.
Your world library
Characters, places, factions — everything your story is built from.
Chapters & scenes
Planning, drafting, blueprints, and keeping a long story straight.
Comics
Drawing scenes as lettered comic pages, by hand or with Manta.
Versions & branches
Save points, what-ifs, and going back.
Credits & AI models
What uses credits, what doesn’t, and your own keys.
Your account
Signing in, your username, your profile.
Taking your work with you
Your book as a file, exports, backups, and handing the story to a game team.
The Windows app
Writing with no internet, and keeping your computer in step with the web.
When you see this message
What it means, in plain words, and what to do next.
- “someone else changed this while you were editing — reload and reapply your change”
- Someone else, or you in another tab, saved the same thing first. Reload and make your change again; nothing was overwritten.
- “the project changed while this write was in flight — retry”
- Someone switched the project’s branch just as you saved. Try again.
- “is locked — complete earlier chapters first”
- Chapters unlock in order. Until the ones before it are finished, a chapter takes planning only — titles, summaries, outline scenes, point of view and subplots. More
- “Limit reached”
- That credit allowance is used up for now. What you can do
- “no model configured for task profile …”
- No AI model is set up for that kind of work. Choose one in Settings › AI Models, or add a key in Settings › API Keys.
- “Needs an internet connection”
- You’re offline in the Windows app. Everything you write is saved on your computer; this part of MantaInk comes back when you’re online. What works offline
- “Viewers can't edit. Ask the owner for editor access.”
- You’re a viewer on this project: you can read it and ask Manta about it, but not change it. Ask an owner to make you an editor. What each role can do
