Transept AI

Quick answer

Transept AI — AI translation that remembers your terminology, tone, and context forever. It's freemium. Best for localization agencies managing multi-language projects needing consistent brand voice.

Transept AI is a freemium AI-powered translation platform designed to maintain consistency across documents, languages, and teams by remembering terminology choices, tone preferences, rejected alternatives, and reviewer comments over time. Unlike generic machine translation tools, Transept builds a persistent translation memory that travels with your team, so every new document or language pair benefits from decisions already made rather than starting from scratch. It is best suited for professional translators, localization agencies, and in-house teams who struggle with consistency drift each time a new project or collaborator is introduced. The platform is hosted in the EU on Hetzner infrastructure in Germany and operates under a strict no-training-on-your-content policy, making it a strong choice for teams handling sensitive or proprietary content. Transept competes directly with tools like DeepL but differentiates itself by storing not just final approved strings but also rejected alternatives and the reasoning behind reviewer changes, giving teams a richer context layer for future decisions. Pricing is fully transparent and self-serve, with a genuine free tier and no sales call required to get started.
