What is Hiwriter?

HiWriter is an AI email generator that uses OpenAI's GPT-3.5 to produce personalised email messages in seconds. You provide context or a brief prompt, set your preferred tone and length, and the tool generates ready-to-send or ready-to-edit copy. It's designed for sales teams sending outreach and follow-ups, support staff responding to customer enquiries, and marketing professionals creating campaigns. The tool supports over 50 languages, includes real-time editing, and offers export options. A freemium model means you can try it without payment, with paid plans for higher volume use.
