Detect Language vs Google Cloud Natural

Detect Language API identifies the language of arbitrary text across 216 supported languages, returning confidence-scored results for both single and batch requests. It's built for routing, moderation, and translation-pipeline pre-processing, with a free plan available alongside paid volume tiers.

Google Cloud Natural Language analyzes syntax, entities, and sentiment in text using the same machine-learning models that power Google's own products, callable via a straightforward API-key-authenticated REST interface. It includes a free monthly usage tier before per-unit billing applies to higher volumes.
