  "account": "Aishwarya, a software engineer with over five years of experience, faced a common challenge when reaching out to people she didn't know. She would spend hours rewriting the first line of an email before finally closing the tab. Existing AI email tools produced polished drafts that lacked her personal touch, so she never sent them. ColdOpen, built for her, starts from her own writing rather than using a template. Users paste 2-3 messages they have actually sent, and specify their intent (referral, recruiter intro, alumni intro, resume feedback, mock interview, mentoring, follow-up, thank-you, reconnect, reference, switching roles). ColdOpen generates a short \"voice learned\" note (greeting, sign-off, sentence length, habits) for review. It then creates three emails and three subject lines, presented in a side-by-side comparison with non-voice drafts. Green highlights show her original phrasing, pink marks generic template phrases, and amber indicates placeholders that need to be filled before sending. The demo is live at https://coldopen-fe.onrender.com/ and the code is available on GitHub.",

That could be a referral request, a note to a recruiter, or a question to someone who…",
