Why flowLingua?

🤖 LLM-Powered

Uses DeepSeek, GPT, or Claude as translation engines. Context-aware translations with perfect grammar, not just word-by-word NMT.

🌍 Zero-Shot Languages

100+ language pairs without training data. LLMs understand any language pair natively — no need for per-pair models.

💰 Pay-Per-Use

No monthly subscriptions. Free 5K chars on signup, then $0.50 per 100K characters. Only pay for what you actually translate.

🔌 Simple API

POST /translate. JSON in, JSON out. Compatible with existing tools, SDKs, and libraries. Works with RapidAPI, Apify, and more.

🏠 Self-Hostable

Run on your own infrastructure. No data leaves your network. Docker-compose in one command. Full control over your data.

🔐 Privacy First

Your translated text stays yours. With self-hosted mode, not a single byte reaches external servers. Ideal for sensitive documents.
