Reading ages, page counts, and why the text draft is free of credits
If you build tools—or you just think like someone who does—you eventually ask the same question of a kids story product: which knobs are configuration, and which knobs are billable?
ToviStory makes that boundary unusually explicit. Reading age, page count, language, tone, and story text live on the free side of the ledger. Successful images spend credits. This post is a practical map of those levers so you do not burn picture credits debugging vocabulary.
The knobs that cost 0 credits
Public docs and pricing agree on a clean rule:
| Work | Credits |
|---|---|
| Create account | 0 (free signup, no card required) |
| Story draft | 0 |
| Text revisions | 0 |
| Character profile analysis | 0 |
| PDF download | 0 |
| Successful image (portrait / page / background / style variant) | 1 |
| Failed image | returned automatically |
That is why the text draft being free of credits matters. You can treat the manuscript like a spec: change reading band, cut sentences, swap tone, regenerate wording—without touching the image budget. Most “AI story” frustration I see in parent chats is actually spec thrash paid for as image thrash. This metering model pushes you to thrash on the free side first.
Reading ages (product bands)
Homepage generator + FAQ:
| Band | Ages |
|---|---|
| Toddler | 1–3 |
| Preschool | 3–5 |
| Kids | 59 |
| Pre-teen | 912 |
FAQ also mentions teen and adult writing options. The site frames these bands as guiding vocabulary, sentence length, and words-per-page. Separately, you set page count: 8–16 body pages, plus cover and back cover.
Builder takeaway: age is not a prompt adjective you hope the model notices. It is a first-class control. Page count is another. Do not discover you wanted 8 pages after you have already illustrated 14. Covers still generate as images when you illustrate them—so length decisions cascade into credit math.
Language and style are also “set once” controls
Per book:
- One story language (editor offers 19, including English, Spanish, French, German, Simplified Chinese). You can change language later and regenerate text.
- One art style guiding portraits and page art. Marketing claims 15 styles; the public carousel names at least: 3D Animated, 2D Cartoon, Watercolor, Storybook Classic, Soft & Dreamy, Comic, Paper Craft, Pencil Sketch.
Pick style before you pay for a portrait. A watercolor portrait will not happily become your comic-page reference without another image spend (style variants are called out as credit-using images on pricing).
Homepage copy even gives directional hints: watercolor for soft bedtime, 2D cartoon for silly adventure, storybook classic for a keepsake. Use those as defaults if you do not want to bike-shed.
Why free text still is not a free illustrated book
The official guide is blunt: a new cast may need a portrait in the selected art style before you can request a draft, and free text generation does not mean a fully illustrated first book is free.
Example cost from that guide:
1 portrait
+ 8 story illustrations
+ front cover
+ back cover
= 11 credits
Extras and successful regenerations add 1 credit each. Failed jobs refund.
Packs (one-time, valid 12 months, no auto-renewal on the pricing page):
| Pack | USD | Credits |
|---|---|---|
| First Spark | $1.99 | 50 |
| Story Maker | $15.99 | 400 |
| Story Shelf | $46.99 | 1200 |
About ** $0.04 / image** appears as a site shorthand. Terms still contain generic subscription-renewal wording; buy against the pricing pages one-time pack facts. Credit history shows expiration per batch—plan a shelf inside the 12-month window rather than assuming infinite rollover.
A builder-friendly order of operations
- Create / reuse cast — preset, describe, or authorized photo; prepare portrait (this spends credits).
- Configure free dials reading age, page count, language, tone/genre (e.g. Bedtime + warm + calm).
- Draft and edit text — still 0 credits. Include a small problem and an ending direction (guide suggestion).
- Illustrate in the page editor — scene + character references; inspect early pages before batch-spending.
- Adult review — every page before a child sees it.
- Read in library or download PDF — PDF does not spend credits.
Reusable character references are the architectural point of the product versus a text-only chat workflow: save the cast, bring them into the next story, keep books in a library. The homepage comparison table lists exactly those gaps in chat-only setups (no saved cast, no page editor, no reading-level control, no PDF path, no library).
Limits worth coding into your expectations
- Adult-managed accounts (parents, guardians, educators, other adults). Kids contribute; they do not get independent accounts per Privacy/Terms framing.
- Character consistency = reference help, not a guarantee of identical details every page. FAQ: AI details can vary; review and regenerate.
- Authorized photos only; project storage covered by Privacy Policy; site states customer stories/reference images are not used to train their own general-purpose models.
- Review before share. Safety is a human gate, not a marketing badge.

I am curious—if you were designing this metering model, would you still keep text at zero, or would you meter draft regenerations too? Feedback welcome in the comments.
