Smartling

Smartling is a LanguageAI translation platform that handles the full localization lifecycle for enterprise content — websites, applications, marketing materials, and technical documentation. The platform combines AI-powered machine translation with human linguist review, automated workflows, and deep integrations with existing tech stacks.

What makes Smartling different from basic translation tools is its hybrid approach. The AI engine pre-translates content using context-aware machine translation enhanced by retrieval-augmented generation (RAG) that pulls from your glossaries and translation memories at the moment of translation. Human linguists then review and refine the output to ensure cultural appropriateness and brand consistency.

Smartling reported 218% growth in AI translation volume in 2025, reflecting broader enterprise adoption of AI-assisted localization. The company claims customers can triple their translation output at 60% less cost and 6x faster turnaround compared to traditional workflows.

How It Works

Smartling sits between your content sources and your published translations. The platform automatically detects new content from connected CMSs, code repositories, or file uploads, then routes it through configurable workflows. These workflows can range from fully automated AI translation to multi-step human review processes depending on content type and quality requirements.

The AI Hub lets you choose your AI translation provider and configure prompt engineering with RAG functionality. An AI Post-Editing Agent automatically checks grammar, tone, and semantic accuracy, while hallucination detection flags potential LLM errors and routes affected content to alternative translation workflows.

File Format Support

Security & Compliance

Smartling holds SOC 2 Type II, HITRUST, HIPAA, PCI DSS Level 1, ISO 17100, and ISO 9001:2015 certifications. The platform is GDPR-compliant with customizable DPAs, making it suitable for regulated industries including healthcare, finance, and enterprise SaaS.

Pricing

Smartling uses a tiered SaaS model with Core and Enterprise plans. Pricing is not publicly listed — you need to contact sales for a custom quote based on your translation volume, language pairs, and feature requirements. The platform includes rate cards for translation services, real-time job cost estimates, custom billing reports, and API integration with finance systems for cost tracking.

Who Should Use This

Smartling is built for enterprises with significant, ongoing localization needs across multiple languages and content types. Brands like IHG Hotels & Resorts, Shopify, Pinterest, State Farm, British Airways, and Lyft use the platform. If you translate occasionally or only need a few languages, lighter-weight tools may be more cost-effective.
