AI email writer — professional emails in seconds
Give the API a brief and it writes the email: the right register, the right length and a structure that fits the purpose. Templates and smart replies are part of the same endpoint.
Sales tools, support desks and productivity apps use it to remove the blank-page step.
Spelling & grammar check, summariser and text compare
Three writing tools behind one API: spelling and grammar correction, summarisation of long documents, and a comparison that highlights what changed between two versions and how similar they are.
Editors, CMS platforms and document tools use it without wiring three separate services.
