Frequently asked questions
How does the Humanise feature work?
It runs a two-step process. First, it analyses your answers to 3–4 questions and builds a voice profile: your sentence rhythm, vocabulary register, and distinctive phrases. Then it generates the letter using that profile as a style constraint. The result sounds like you because it was modelled on how you write.
Will AI detectors flag my letter?
Humanise makes detection substantially harder by varying sentence length (burstiness), avoiding statistically common AI phrases, and matching your register. We can't guarantee zero detection — no tool can — but it dramatically reduces the risk.
Does BlitzLetter store my CV?
No. Your CV is sent to the Claude API for generation and is not persisted after the request. Only the finished letter is saved (Pro and Pro+ plans). See our privacy policy for full details.
What roles does it work for?
Any role with a written cover letter requirement. BlitzLetter is designed for UK and European applications but works for any English-language role globally. It covers three tiers: internships, graduate roles, and mid-to-senior positions.
Can I cancel my subscription?
Yes, any time. Monthly plans cancel at the end of the billing period. Annual plans are refundable within 7 days if you've generated fewer than 5 letters.
What data do you share with Anthropic?
Your CV text and job description are sent to Anthropic's Claude API to generate the letter. This is covered in our privacy policy. We do not attach identifying metadata to the prompts.
