I will add google, deepl and ai translation to your app with glossary support


About this gig
Add real translation to your product (website, backend, mobile app or SaaS) using Google, DeepL, LibreTranslate, MyMemory, Baidu or any OpenAI-compatible LLM, and keep it running when one provider fails.
This is exactly what my own product LinguaFlow does: a C++17 translation core that routes each request through several engines with health-based fallback, enforces a glossary so product names and technical terms stay consistent, caches results, supports cancellation and runs on macOS, iOS and Android. I package the same approach for your stack.
What you get:
- A clean translation API/SDK in Node.js, Python, C++ or Dart, or a REST microservice
- Language detection, batch translation and caching
- Multi-engine routing with automatic fallback, so one outage does not break your feature
- Glossary / terminology enforcement and optional LLM post-editing for tone
- Automated tests, usage logging and a handover document
- Optional UI: translation screen, history, export, side-by-side engine comparison
Message me with your stack, expected volume and the languages you need, and I will confirm the right package before you order.

FAQ
Which engines are supported?
Google Translate, DeepL, LibreTranslate, MyMemory, Baidu Translate and any OpenAI-compatible LLM (OpenAI, DeepSeek, Qwen, a local Ollama). Other providers on request.
Do I need my own API keys?
Yes. Keys are created in your provider accounts and stay in your infrastructure. LibreTranslate and MyMemory have free tiers, so you can start without paying a provider.
Can it run fully offline?
Routing, glossary and caching work offline; the translation itself needs either an online engine or a local LLM (Ollama) running on your server.
Which languages are supported?
Whatever the chosen engines support: 100+ for Google and LLMs, 30+ for DeepL. Right-to-left languages are handled correctly in the optional UI.
