Traditional translation services break these formats, mangling keys, placeholder variables and Markdown syntax. i18n Web instead sends whole batches of key-value pairs or segmented documents to large language models, giving the model surrounding context so terminology stays consistent across a page. The workflow is deliberately simple. You drag a .json, .md, .mdx or .txt file onto the page, pick the target languages, optionally list object keys you want to leave untouched, and add extra context about your product so the model can interpret ambiguous terms correctly. Translations are then shown in an in-editor view where you can review and tweak them before downloading either a single file or a packaged archive of all language versions. Because LLM calls cost real money and the service enforces rate limits, the free tier is bounded: two files and two language versions per request, up to 30 key-value records per JSON file and roughly 2,000 characters per document. Paid plans raise those ceilings significantly and remove queueing. The site is a self-serve product rather than a full translation-management suite — there is no glossary management, team workflow or string-library sync. **Pricing & Plans:** Freemium [Profile (Markdown)](https://openaitools.app/tool/https-i18nweb-com.md) ## JustI18n JustI18n is a lightweight, browser-run localization workbench aimed at developers who ship multi-language products. Instead of exporting spreadsheets or wiring up a complex translation pipeline, you load a resource bundle, let ChatGPT produce the target-language strings, and download the finished file back into your project. It supports JSON key-value files, Chrome extension message files, and Java properties bundles — the three formats most commonly used by web extensions, front-end apps, and Java services. One of the tool's practical advantages is how it handles the awkward parts of machine translation for UI copy: it keeps your source keys intact, performs a basic length/compatibility check so long translations don't silently break layouts, and lets you regenerate any single item rather than redoing an entire file. Because processing happens locally in the browser with your own OpenAI credentials, you keep control over API usage and cost. JustI18n is a small, self-serve project rather than a full translation management system. There is no collaborative review workflow, glossary management, or human-translator marketplace built in, so teams that need those features may pair it with a dedicated TMS. For solo developers, indie app makers, and small teams who want a fast first pass at localization, it offers a focused, low-friction starting point. **Pricing & Plans:** Freemium. The site offers a free tier you can use with your own OpenAI API key, and mentions premium features plus a license key option for expanded use. Exact prices are not published on the homepage — check the site for current terms. - **Multiple bundle formats:** Load JSON key-value files, Chrome extension message files, or Java properties resource bundles without converting them first. - **Bring your own OpenAI key:** Translations run against your own OpenAI API key, so usage and billing stay under your control. - **Run locally in the browser:** Files are processed in your browser session with no need to stand up a backend translation service. - **Per-item regeneration:** Regenerate individual translated strings instead of rebuilding the whole resource file. - **Length and compatibility check:** Flags translations whose length may break your UI layout before you ship them. **Strengths:** Supports the three resource formats most developers actually use; Uses your own OpenAI key, keeping cost transparent; No install or backend setup — runs in the browser; Fine-grained regeneration avoids re-translating whole files **Limitations:** Requires an OpenAI API key and associated spend; No built-in human review or glossary workflow; Lightweight project without a large feature set or integrations [Profile (Markdown)](https://openaitools.app/tool/justi18n.md) ## Frequently Asked Questions ### How do i18n Web and JustI18n compare in monthly traffic? i18n Web has 0 monthly visits, while JustI18n has 0.
