Open-Core Product & Cloud SaaS Model

While our open-source Community client lets developers test short plain-text excerpts with personal API keys, translating 200-page academic PDFs and legal contracts requires high-concurrency rate limits, long-context caching, and complex layout preservation.

ZiyuanLingo Cloud Pro ($19/month) and Team Cloud ($49/seat/month) run natively on Google Cloud (Vertex AI, Cloud Run, and Cloud Storage)—delivering zero-config multi-model translation, asynchronous PDF reconstruction, and real-time 3-tier glossary synchronization.
