Keyword extraction to generate subject lines

A computer-implemented method comprising:

• obtaining an original list of keywords based on a body of text using a trained machine learning model;
• generating a prompt to a large language model (LLM) for generating a subject line, the prompt including a chosen list of keywords based on the original list of keywords, wherein the prompt does not include the body of text;
• and
• obtaining, from the LLM responsive to the prompt, at least one generated subject line corresponding to the body of text.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a system, causes the system to:

• obtain an original list of keywords based on a body of text using a trained machine learning model;
• generate a prompt to a large language model (LLM) for generating a subject line, the prompt including a chosen list of keywords based on the original list of keywords, wherein the prompt does not include the body of text;
• and
• obtain, from the LLM responsive to the prompt, at least one generated subject line corresponding to the body of text.
