Frequently Asked Questions

Everything you need to know about FlowLingua localization engine.

01 How does FlowLingua differ from DeepL or Google Translate?

DeepL and Google Translate perform word-by-word or syntactic translations. FlowLingua rewrites and adapts the message according to your chosen tone of voice (professional, casual, formal) and regional cultural norms.

02 Which languages and regional registers are supported?

We currently support over 40 locales, including key combinations such as UK Professional, US Casual, LATAM Casual (with regional idioms), DE Formal, FR Corporate, and ES Spain.

03 Can I integrate FlowLingua into my own API or CMS?

Yes! Pro and Agency subscribers get full access to our documented REST API with OpenAPI specs, TypeScript and Python SDKs, and cURL examples.

04 What happens if I exceed the Free plan limit?

On the Free plan, usage pauses until the next monthly billing cycle. You can upgrade at any time to the Pro plan for just $9/mo to get unlimited characters.

05 How does FlowLingua protect my data privacy?

All data in transit is encrypted via TLS 1.3 and is never used to train public models without your explicit consent.
