$30 once
The whole writing app: binder, editor, notes, story bible, tags, outline, timeline, goals, import, export, and backups. Works with AI switched off. No subscription.
$0 to us
Add an OpenRouter key (the default: one key for many models) or an OpenAI key and pay the provider directly for what you use, or point MythScribe at a model on your own computer (Ollama, LM Studio) and pay nothing.
Pay as you go
For writers who would rather not manage a key: one balance, every model, pay only for what you use. Top up $10, $25, or $50 in real dollars that never expire, billed at the model’s cost plus 25%. Try the AI for $5. Any unused balance is refundable for 30 days.
A rough estimate, not a quote: about $6 a month for a writer who adds 1,000 words a day, keeps background indexing on, takes about 20 VibeWrite suggestions a day, and asks the assistant 3 questions a day, with an OpenAI key on the app’s OpenAI models (GPT-5.4 mini for background work and suggestions, GPT-5.4 for the assistant) at OpenAI’s prices of 5 October 2026. The OpenRouter defaults (DeepSeek V4 Flash and Pro) are priced lower per token.
| What | Assumption | Rough cost |
|---|---|---|
| Background indexing | Summaries, story bible, and tags for about 30,000 new words | about $0.60 a month |
| VibeWrite | About 20 suggestions a day | about $0.80 a month |
| Assistant | About 3 questions a day, each with a few lookups | about $4.60 a month |
| A line edit | One pass over a 90,000-word novel, when you run it | up to about $2.50 each time |
Your own numbers depend on how you write and what you ask. The app shows the cost of every request and a running total, the edit-pass screen shows an estimate before you start, and the daily cap (set to $2 when you install) stops requests once it is reached. A local model costs nothing.
