FAQ

Pricing FAQ

Is WriterStudioAI really a one-time purchase? ▾
Yes. WriterStudioAI is a local-first software. You buy the Starter ($39) or Pro ($349) license once, download the app, and you can write and export your books forever. Pro Annual ($149/year) is available for those who want recurring credits refreshed annually.
What happens when I run out of AI credits? ▾
If you run out of the included AI writing words or cover image credits, you can purchase top-up token packs starting at just $3. Alternatively, if you are on the Pro or Pro Annual plan, you can connect your own API key (e.g. OpenAI, DeepSeek, or Anthropic) and write completely unlimited without purchasing refills.
Can I upgrade from Starter to Pro? ▾
Yes, you can upgrade at any time. Simply purchase a Pro license and apply it in the app to unlock the Bring Your Own Key (BYOK) functionality and add 2.5 million words to your account.
Are updates included in my one-time purchase? ▾
Yes! Lifetime updates are included for all Starter and Pro one-time purchase licenses. Your desktop app will automatically update via GitHub Releases whenever we launch new features.
What is the refund policy? ▾
We offer a fully functional free trial (no credit card required) so you can test the software on your machine before purchasing. Because of the immediate cost of preloaded AI credits, we generally do not offer refunds once a license key is activated.
