One account, pay-per-generation

Three subscriptions for one book. You'd use minutes of Midjourney, 16% of ElevenLabs, and one Suno track.

$3.90 vs $60/mo. A self-published author creating 3 books/month generates $11.69 of content vs $60.

No unused credits

Subscriptions charge for capacity you do not use. FairStack charges for what you generate. Nothing more.

One account, all modalities

Video, voice, image, music, sound effects -- all from one platform. No juggling 3 subscriptions.

One price list, shown with its settings

Every rate on this page comes from the same public price list as the API quote, and is shown beside the settings it is priced at.

Frequently asked questions

Can I maintain a consistent art style across all 12 pages?
Yes. Use the same prompt style and character descriptions for every illustration with GPT Image 2.5 Flare. Tip: include 'in the style of [description]' in every prompt to keep the look unified.
Is this good enough for print publishing?
GPT Image 2.5 Flare at medium quality is the setting priced in this breakdown ($0.015804/image (medium, 1:1)). For print-on-demand services (Amazon KDP, IngramSpark), choose the quality that meets the printer's requirements; the high quality setting is $0.063216/image (high, 1:1).
How does the audiobook version work?
Enter your story text, choose a warm narrator voice (or clone your own), and FairStack generates the narration. Add gentle background music and sound effects for a fully produced audiobook. Total runtime depends on story length — ~4 minutes for 8,000 characters.
What about longer chapter books?
Scale linearly. A 30-chapter middle-grade novel with 1 illustration per chapter and ~8,000 characters of narration per chapter is $52.31 at these rates. See our audiobook chapter breakdown for narration-only costs.
