AI email response generator — smart auto reply
Send an incoming email and the API returns a reply written in the right register, ready to send or edit. Templates and tone controls are part of the call.
It fits inbox tools, support desks and sales products where reply time is the metric.
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.
