Most AI cover letter tools just swap in the company name and call it tailored. LetterFlow reads your actual CV and the actual job post together, then writes something specific to both. UK English, no buzzwords, no "I am writing to apply for..." — just a tight 3–4 paragraph letter that sounds like a real person wrote it. Done in about 30 seconds. £2.99 one-time or £7.99/month unlimited.
