AI prompt generator & optimisation API
The API rewrites a prompt to use fewer tokens, enforces a JSON schema on the output and improves answer quality without changing intent. Cost is the measurable part.
It works against OpenAI, Claude, Gemini, Llama and Mistral, so the same optimisation applies whichever model is behind the product.
AI sentiment analysis & emotion detection
Beyond positive and negative: the API reports emotional tone, the trend across a set of texts and which phrases drive the sentiment.
Feedback tools, social listening and review platforms use it to explain a score rather than just show one.
