Per-locale guardrails

Every generation prompt in the pipeline (research, outline, draft, critic, metadata, FAQ, humanizer) accepts {{language}} and {{locale}} bindings and obeys these rules. The complete spec lives in prompts/_locales.md in the engine.

🇺🇸 en-US English (US)

• US spelling: organize, color, optimization, analyze.
• US idiom and conventions.
• Period decimal (1.5), comma thousands (1,000), $ currency.
• MM/DD/YYYY dates by default.

🇬🇧 en-GB English (UK)

• British spelling: organise, colour, optimisation, behaviour.
• British idiom: 'in hospital', 'at the weekend', 'high street'.
• £ currency, period decimal, comma thousands.
• DD/MM/YYYY dates. 'whilst' fine; 'gotten' is not.

🇩🇪 de-DE Deutsch (Germany)

• Sie-form by default for B2B; du only when site tone is consumer/casual.
• ß used correctly (groß, Straße) — not 'ss' substitutions.
• German thousands separator 1.000, comma decimal 1,5.
• € postfix with non-breaking space: '1.000,00 €'.
• DD.MM.YYYY dates. All nouns capitalised.

🇫🇷 fr-FR Français (France)

• Vous-form by default. Tu only when site tone is casual.
• Non-breaking space before ; : ! ? » and after «.
• French quotation marks: « ... » with NBSPs inside.
• Comma decimal 1,5, space thousands 1 000.
• € postfix with NBSP: '1 000,00 €'. DD/MM/YYYY dates.
• Sentence-case headings — no English title-case.

🇪🇸 es-ES Español (Spain + LatAm)

• Castilian Spanish by default. Vosotros plural informal, usted formal singular.
• LatAm region hint switches vosotros → ustedes and shifts idiom.
• Comma decimal 1,5, period thousands 1.000.
• € postfix: '1.000,00 €'. DD/MM/YYYY dates.
• Inverted opening punctuation: ¿…? and ¡…!.

🇮🇱 he-IL עברית (Hebrew, RTL)

• Right-to-left rendering with proper dir='rtl' on every article.
• No niqqud — adult Hebrew omits vowel marks. Children's-book typography is filtered out.
• Brand names and technical terms stay in Latin script (Stripe, Kubernetes, API). The Hebrew sentence flows around them.
• Gershayim ״ for double quotes, geresh ׳ for single — never ASCII " or '.
• No capital letters — Hebrew has no capitalisation. Metadata writer never tries.
• DD/MM/YYYY dates, period decimal 1.5, comma thousands 1,200.
• Shekel sign ₪ postfix-positioned: '1,200 ₪'.
• Mixed-direction titles (Hebrew + Latin script): LRM/RLM markers inserted automatically by the renderer.
• Gender-inclusive phrasing: prefer infinitive constructions and plural-neutral forms over masculine-as-default.

How locale plays with the rest of the pipeline

• AEO scanning — every scan is locale-scoped. Prompts, citations, share-of-voice, and competitor analysis all run per region.
• Brand profile — tone, audience, and pitch rules are written and applied in the target language; you don’t need to translate them.
• Reflection critic — graded against locale-specific rules. Hebrew niqqud appearing in output? The critic flags and triggers a rewrite.
• Metadata + FAQ — meta titles, descriptions, FAQ blocks, and JSON-LD inLanguage are all set to the article’s locale.
• Image alt text — written in the target language; the image style brief is interpreted as visual identity, not language.
• RTL rendering — Hebrew articles ship with dir="rtl" at the article level; mixed-direction strings get LRM/RLM markers automatically.

Tier-2 roadmap

On the 2026 H2 roadmap (no firm date — driven by customer demand): pt-BR, it-IT, nl-NL, ja-JP, zh-CN, ar-SA. If you need a specific locale prioritised, email admin@mentionwell.com.
