How it works
Three steps. Under a minute.
No prompting, no templates to fill in.
Paste your CV and the job description
Upload or paste both. BlitzLetter pulls out the company, the role, and the requirements that matter. No prompting, no forms.
Give it your voice (optional)
Answer three quick questions or paste a sample of your own writing, and the letter is built on your sentence rhythm and vocabulary rather than a template’s. Skip it and the letter still works.
Get a letter that’s actually about you
Grounded in your real experience and the specific job. Copy it, send it, usually inside 60 seconds. Pro adds Humanise, .docx download and saved history.
Why BlitzLetter
Generic AI tools write letters that could be about anyone.
BlitzLetter writes yours.
Voice matching (optional)
Paste a sample of your own writing and the letter mirrors your rhythm, vocabulary, and tone. It reads like you because it is built from you. Leave it out and nothing else about the letter changes.
Specific, not generic
Every claim in the letter is drawn from your CV and the job posting. No stock phrases, no adjective soup, nothing that could apply to any candidate.
“I am a passionate team player with excellent communication skills.”- “I ran the migration you describe in the posting: 40 services, zero downtime.”

FAQ
Frequently asked questions
What does the Humanise feature do?
It rewrites your letter so it reads like something a person actually sat down and wrote: varied sentence lengths, natural rhythm, plain word choices, and none of the uniform phrasing that gives AI writing away. It works entirely on its own, so you do not need to hand over a writing sample to use it. We make no promise about what any AI-detection tool will say, because nobody honestly can.
Is Humanise the same as voice matching?
No, they are two separate features. Humanise makes the letter read as human written. Voice matching is an optional extra: paste 200 or more words of your own writing, or answer a few quick questions, and the letter mirrors your rhythm, vocabulary, and tone. Use either one on its own, both together, or neither.
Will AI detectors flag my letter?
We don’t promise anything about detectors, because nobody honestly can. Detection is a moving target and results vary by tool and by day. What we actually do: write the letter in your voice, from your real CV and the real job posting, with varied sentence rhythm and none of the stock phrases that make letters read as generic. A letter grounded in your specific experience is a better letter, whatever a detector says.
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, from Account → Billing. Cancelling stops the next payment and you keep your plan until the end of the period you have already paid for. Cancelling is not a refund of the current period, but if something did not work on our end, contact us and we will put it right or refund you. Full details are on the refund policy page.
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.
