Transloop

Updated July 24, 2026

Overview / Description

Transloop is an AI translation tool that provides real-time, context-aware translation across 120+ languages with sub-50ms latency, built for development teams and businesses that need to localize apps, websites, documents, and customer interactions at scale. Unlike general-purpose translation APIs, Transloop's AI models are trained to understand idioms and industry-specific terminology, reducing the glossary maintenance burden on engineering teams.

The platform offers a developer-first API with SDKs for Python, Node.js, Go, and other languages, enabling teams to integrate translation directly into their product without rebuilding infrastructure. Shared glossaries and translation memory tools let team members maintain consistency across projects, while batch processing handles thousands of strings simultaneously for bulk document or product-string localization jobs. The service is SOC 2 Type II certified and uses AES-256 encryption, covering enterprise security requirements. Transloop reports a 99.2% accuracy rating and has 10,000+ API users.

Pricing includes a free Starter tier (50,000 characters/month, 10 languages), a Professional plan at $49/month (2 million characters/month, 120+ languages, priority support), and Enterprise at custom pricing (unlimited characters, dedicated model tuning, SLA guarantee). Notable users include teams at Shopify, Notion, Stripe, Figma, Linear, and Vercel.

Cons
