Best AI Translation Tool

Its signature Context feature shows real translated example sentences pulled from movies, books, news, and legal documents so users can see how a phrase is actually used, alongside definitions, synonyms, pronunciation, and verb conjugation.

Beyond the free tier, Reverso Premium and Pro subscriptions add unlimited long-text translation, ad-free apps for PC, Mac, iOS, and Android, and document and PDF translation with higher word limits. A corporate plan adds custom volumes, SSO, and API access. Browser extensions also translate selected text and video subtitles on services like Netflix and YouTube.

ModernMT is an adaptive neural machine translation engine built by Translated that learns in real time from human corrections and uses document-level context, drawing on up to 100,000 words of surrounding text, to improve translation accuracy.

New account registrations on modernmt.com are closed, existing API keys keep working until December 31, 2026, and customers are being migrated to Lara plans. Historical pricing was volume based, ranging from about $8 to $50 per million characters depending on the service tier.
