Robo Translator
Robo Translator is a pay-as-you-go localization service for translating text, audio, and video content into multiple languages. Built by Erudika, it uses OpenAI models for machine translation and Azure Cognitive Services for speech-to-text and text-to-speech.
You can translate documents, auto-translate and synthesize YouTube captions into multi-language audio tracks, transcribe and dub audio in one click, and localize software strings in formats like XML, JSON, plist, PHP, and properties files.
There is no monthly subscription. You top up a wallet with euros and pay per token for translation, per character for TTS, and per second for STT. New accounts receive €5 in free credits. Uploaded files are encrypted and stored on AWS for up to 30 days before deletion.
