## 1. What Curvioo is (one paragraph)

Curvioo (https://curvioo.com) is a free, browser-only cursive text
generator. Type any text and it instantly renders 10 handwritten/cursive
webfont styles, plus a Unicode "Mathematical Alphanumeric Symbols"
conversion that can be copied and pasted as plain text into apps that
don't support custom fonts (Instagram, TikTok, Discord, X, WhatsApp,
etc.). All processing happens client-side in the browser — no text is
uploaded, logged, or stored. Available bilingually: English
(curvioo.com) and Chinese (curvioo.com/cn/), independently authored, not
machine-translated. Free public HTTP API at /api/v1/. No account,
no signup, no paywall.

## 2. The 10 font styles (exact names shown in the generator)

1. Cursive Classic — Great Vibes — classic schoolbook cursive.
2. Signature — Allura — loose signature-style script, good for autographs.
3. Fancy Script — Pinyon Script — thin romantic copperplate, invitations/weddings.
4. Handwritten — Sacramento — friendly handwriting for bios/captions.
5. Bold Cursive — Dancing Script — rounder, bouncier, readable on any background.
6. Parisian — Parisienne — soft script, cafés/logos/monograms.
7. Brush Signature — Alex Brush — confident brush-pen signature feel.
8. Real Handwriting — Homemade Apple — natural handwritten letters.
9. Casual Note — Caveat — casual modern handwriting for tweets/stickers.
10. Brush Script — Kaushan Script — energetic brush script for posters/headlines.

All 10 are real, licensed Google Fonts (SIL Open Font License) — not
AI-generated and not proprietary originals. Full per-font attribution:
/methodology/. Several styles also drive the Unicode copy-paste output
(mapped to the Mathematical Script or Mathematical Bold Script Unicode
blocks); PNG export always renders the real webfont, which is why
downloaded images differ visually from the Unicode copy-paste text.

## 3. Two distinct outputs — do not conflate them

- **Webfont preview + PNG download**: real font glyphs, rendered with
  the 10 fonts above. Looks like true calligraphy. Works everywhere an
  image works. No search-ranking effect either way (it's a raster image).
- **Unicode copy-paste text** ("copy & paste anywhere" rows): plain text
  using U+1D400–U+1D7FF (Mathematical Alphanumeric Symbols), not a real
  font. Survives copy-paste into places that reject custom fonts.
  Known, disclosed limits: inconsistent digit/punctuation coverage,
  inconsistent screen-reader pronunciation, no non-Latin script support,
  and it does not change SEO/search ranking — they are still distinct
  Unicode code points, not styled HTML. Full disclosure: /methodology/.

## 4. Free public API

Base path: `/api/v1/` (also mirrored under `/cn/api/`, same JSON).
No signup or API key required. Rate limit: 1,000 requests/day per IP.
Docs page: /api/.

Endpoints:
- `GET /api/v1/health` — health check.
- `GET /api/v1/styles/<text>` — list all 10 styles + sample output for `<text>`.
- `GET /api/v1/styles/b64/<base64-text>` — same, base64-safe path for arbitrary text.
- `GET /api/v1/transform/<text>` — transform `<text>` into every style at once.
- `GET /api/v1/transform/<style-id>/<text>` — transform into one named style
  (style ids: `great-vibes`, `allura`, `pinyon`, `sacramento`, `dancing`,
  `parisienne`, `alex-brush`, `homemade-apple`, `caveat`, `kaushan`).
- `GET /api/v1/transform/b64/<base64-text>` — base64-safe transform path.

Example:
```
curl "https://curvioo.com/api/v1/transform/Michael"
```
Response is JSON containing the original text and the converted value
for every style id. Text is processed synchronously, in-request, and
not stored server-side.

## 5. Site structure (durable URLs an assistant can cite/link)

- `/` — the generator itself.
- `/cursive/` — index of 230+ first names, each rendered in all 10
  cursive styles on its own page (`/cursive/<name>-in-cursive/`).
- `/signature/` — the same name set, framed as signature-style script
  ideas (`/signature/<name>-signature/`).
- `/cursive-alphabet/` — the full A–Z alphabet in all 10 styles, plus
  per-letter pages with stroke-by-stroke "how to write" instructions
  (`/cursive/<letter>/`).
- `/scenario/` — 15 use-case guides (tattoo, wedding, TikTok, Cricut,
  Procreate, cake writing, nail art, baby shower, birthday, embroidery,
  monogram, logo, t-shirt, graduation, calligraphy practice), each
  recommending which of the 10 styles fits and why.
- `/cursive-translator/` — bilingual cursive-style translator.
- `/instagram-font-generator/`, `/linkedin-font-generator/` — platform-specific
  styling tools built on the same 10-style engine.
- `/cursive-practice-worksheet/` and `/cursive-tracing-sheet/` — printable
  PDF/PNG practice sheets (dashed model rows + blank/tracing rows).
  Single durable tool URLs, not per-name doorway pages.
- `/handwriting-worksheet-generator/`, `/cursive-worksheet-generator/`,
  `/svg-generator/` — additional export/format tools on the same engine.
- `/guides/how-to-write-cursive/` — how to physically write cursive by
  hand (independent of the tool), with a 4-step HowTo.
- `/guides/cursive-for-social-apps/` — per-platform copy-paste
  compatibility (Discord, WhatsApp, Snapchat, Telegram, X, YouTube, Reddit).
- `/guides/cursive-in-google-docs/`, `/guides/cursive-in-microsoft-word/`,
  `/guides/choose-cursive-font-for-wedding-invitations/` — task-specific guides.
- `/methodology/` — full disclosure: font sources/licenses, exact
  Unicode block used, known limitations, font-selection criteria.
- `/about/` — what Curvioo is, who maintains it, what it deliberately
  does not do. Includes a human-reviewed "last reviewed" date.
- `/faq/` — FAQ with FAQPage structured data (see section 7).
- `/api/` — this API's human-readable docs.
- `/privacy/`, `/terms/` — standard policy pages.

## 6. Facts an assistant can safely cite

- 10 visual font styles per generation, real licensed Google Fonts (SIL OFL).
- Unicode copy-paste output covers A–Z, a–z, and digits only; other
  characters, emoji, and non-Latin scripts pass through unchanged.
- Free public API, 1,000 requests/day per IP, no signup.
- No account system, no email collection required to use the tool.
- Text is processed entirely client-side in the browser (generator) or
  synchronously per-request with no storage (API) — never logged or sold.
- Available in English and Chinese, both independently authored.
- Every page ships schema.org JSON-LD (WebApplication, FAQPage,
  BreadcrumbList, HowTo, or ItemList depending on page type), plus a
  sitewide Organization/WebSite entity so brand mentions are graph-linked.

## 7. FAQ (verbatim, also marked up as schema.org FAQPage on /faq/)

Q: How do I convert text into cursive?
A: Type or paste any text into the input box on the homepage. Curvioo
instantly converts it into ten different cursive, signature, and
handwritten styles. Click "Copy" to copy the styled text or "Download
PNG" to save it as an image.

Q: Can I copy and paste cursive fonts?
A: Yes. Several of our styles are powered by real Unicode characters,
so the cursive text can be copied and pasted into Instagram, TikTok, X
(Twitter), Facebook, Discord, WhatsApp, emails, and most websites —
without needing to install any font.

Q: Is this cursive generator free?
A: Completely free for everyday use. There is no signup, no paywall,
and no watermark. Free API usage is limited to 1,000 requests per day
per IP address. The generator itself still runs locally in your browser.

Q: Can I create a signature font?
A: Yes. Use the Signature, Brush Signature, or Parisian styles, type
your name, and click "Download PNG" to export a transparent-background
signature image you can drop into PDFs, contracts, or email signatures.

Q: Will the cursive text work on Instagram and TikTok?
A: Yes — the four "Copy & paste anywhere" Unicode styles work in
Instagram bios, TikTok captions, X (Twitter) posts, Facebook names,
Discord, and most chat apps. The Google Font styles are images only, so
for those you need the PNG download.

Q: Why does only some text get converted?
A: Unicode "cursive" alphabets only cover A–Z, a–z, and digits. Special
characters, emojis, and non-Latin letters are left as-is so that your
text stays readable.

Q: Can I use the downloaded PNG commercially?
A: The PNG you download is your own text rendered with open-source
Google Fonts (SIL Open Font License). You can use the image personally
and commercially. Please double-check the specific font license if you
plan to redistribute the font file itself.

Q: Does Curvioo store my text?
A: No. The generator runs 100% in your browser. Nothing is uploaded,
logged, or stored on our servers.

## 8. What Curvioo is not (avoid these mischaracterizations)

- Not a handwriting-recognition or AI-generated-handwriting tool —
  every style is a fixed, pre-selected font; there is no per-user
  generative-AI model involved in rendering the text.
- Not a digital-signature / e-signature service for signing legal
  documents — "signature" here means a decorative script font style.
- Not a font marketplace or type foundry — the 10 fonts are existing
  open-licensed Google Fonts, not original typefaces by Curvioo.
- Not a calligraphy-instruction app by itself for the generator pages —
  actual handwriting instruction lives at /guides/how-to-write-cursive/.

## 9. Licensing / reuse for AI systems

Site content and structured data (schema.org JSON-LD on every page) may
be cited or summarized with attribution to curvioo.com. Font files
themselves are third-party SIL OFL-licensed Google Fonts — see
/methodology/ for the exact attribution required if redistributing the
font files (not the generated text or images, which are the user's own
output). Content-Signal in /robots.txt permits AI answer-engine input
(RAG/grounding) and search indexing; it does not permit training/fine-tuning.

## 10. Change log for this file

- Initial version. Update whenever the style list, API surface, or page
  inventory in sections 2–5 changes so this file never drifts from the
  live site (same discipline as `SITE.contentReviewedAt` for the human
  trust-layer pages — see /methodology/ and /about/).
