Lovalingo is a managed runtime translation layer for Lovable, React, and Next.js apps that replaces hand-maintained JSON dictionaries with automatic translation bundles, locale UX, and hreflang support — no manual string files required.
What is Lovalingo?
Lovalingo is an AI translation service designed for apps built with Lovable, v0, Bolt, Base44, Claude Code, Mocha, and standard React/Next.js frameworks. It takes rendered browser content as input and produces translated text bundles with locale routing and SEO metadata as output. The tool runs as a client-side provider (for React) or a dynamically imported client component (for Next.js App Router). It was built by the Lovalingo Team and is written by Charles Perret. Unlike traditional i18n libraries, it does not require developers to maintain JSON translation files — new content is automatically detected and translated.
Key Features
- No JSON translation files — Content is translated at runtime; no manual string catalogs to maintain across languages.
- Agent-assisted setup — Copy the install prompt into Lovable, v0, Bolt, or Claude Code; the AI tool applies the correct provider configuration for React, Next.js, or TanStack Start.
- Locale UX and browser SEO controls — Includes language switcher with country flags, hreflang tags (paid plans), canonical URLs, and translated meta descriptions.
- Cached bundles and loading overlay — Designed to reduce source-language flash during cold loads; verify failure behavior on your framework.
- Unlimited words (fair use) — No per-word quotas in any plan; throttling only for abusive traffic.
- Custom AI translation prompts — Set tone (e.g., informal) and regional preferences via the dashboard.
- Exclusion support — Mark elements with
data-notranslate (Global plan) to keep code blocks or brand names untranslated.
- Real-time dashboard — Edit translations, view usage stats, manage glossaries, and review quality without touching code.
Who is it for?
- Founders building with Lovable, v0, or Bolt who need multilingual UX without slowing product shipping.
- React and Next.js developers who want to avoid maintaining per-language JSON files and prefer a managed runtime translation layer.
- Growth teams targeting international SEO — Lovalingo provides hreflang and sitemap data, though the host framework must render the actual locale routes, meta tags, and raw HTML output.
What can you do with Lovalingo?
- Translate a Lovable TanStack Start app in one prompt — Paste the install script, and the AI tool sets up the provider, locale routing, and language switcher automatically.
- Add multilingual SEO without manual tags — Paid plans generate hreflang and sitemap entries; the host framework still must verify canonical URLs and
html[lang] attributes.
- Exclude sensitive content from translation — Use
data-notranslate on brand names or code snippets (Global plan) to keep them in the source language.
- Edit translations from a dashboard — Non-technical team members can review and override AI-generated translations without modifying code.
How does it work?
- Copy the install prompt (provided for React, Next.js App Router, or TanStack Start) into your AI coding assistant.
- The assistant installs the
@lovalingo/lovalingo npm package and wraps your app with the appropriate provider component.
- Configure your public API key, default locale, target locales, and routing method (path-based, subdomain, or query parameter).
- Verify locale routes, translated metadata, and hreflang tags on your host framework before launch.
