site2voice 0.5.3

Ready-to-use VOICE.md copy profiles and optional benchmarks for AI-generated copy.

site2voice

Drop-in VOICE.md copy profiles. Pick a public writing pattern, save one file, and your agent writes less generic copy.

site2voice is not a visual design-system library and not a brand-cloning tool. It turns public copy into a compact, reference-only writing contract: sentence rhythm, heading shape, CTA verb shape, claim boundaries, and benchmark gates.

No install. No JSON. No generation step.

Not official. Not affiliated. Not permission to impersonate a brand.

Use

Download one copy profile as VOICE.md:

curl -L https://raw.githubusercontent.com/SihyeonJeon/site2voice/main/voices/stripe.md -o VOICE.md

Tell Claude Code, Codex, Cursor, or Copilot:

Use @VOICE.md as a copy contract for headings, CTA shape, paragraph rhythm, and UI microcopy.

Each file is a plain Markdown writing brief with sentence rhythm, heading shape, CTA verbs, content boundaries, claim boundaries, and a benchmark target. The public profiles remove source nouns, raw CTAs, navigation labels, paragraph samples, logos, screenshots, and brand assets.

Reference names identify the public page used for measurement. They do not imply sponsorship, endorsement, affiliation, or permission to reuse protected brand identity. See Brand Usage.

Not DESIGN.md

DESIGN.md describes visual identity: colors, typography, spacing, components, layout, and responsive behavior. VOICE.md describes writing behavior: rhythm, CTA shape, information order, claim safety, and copy-safety gates.
