Built for students who hate writing cover letters.
BlitzLetter started as a personal fix for a very specific kind of misery: spending three hours writing a cover letter for a role you probably won't hear back from anyway. There had to be a better way.
The story
In my second year of university I applied to over 60 internships. Not because I enjoyed applying — because I knew the numbers game. The problem was every half-decent company expected a tailored cover letter, and writing one properly took between 45 minutes and two hours. I was burning entire weekends on cover letters instead of actually building things.
I tried ChatGPT like everyone else. The output was instantly recognisable — the same “I am passionate about” opener, the same hollow structure, the same adverbs. Recruiters have read thousands of these. I built a quick script to get around it: a structured prompt that pulled from my CV, matched the JD, avoided the worst phrases, and varied the sentence rhythm. It wasn't pretty, but the letters were good. I got significantly more interviews that cycle.
After a few friends asked to use it, I decided to turn it into something real. BlitzLetter is that tool — properly designed, with the voice-matching and role-tier logic baked in, and fast enough that you can blitz through applications without losing your whole weekend to them.
What makes BlitzLetter different
Voice matching
The Humanise feature extracts your writing style from your answers to a few questions, then generates the letter in that voice. It reads like you wrote it because it was modelled on how you write.
Role-tier aware
An internship letter and a senior engineer letter need completely different structures and tones. BlitzLetter adjusts automatically — trajectory and projects for internships, business impact in numbers for senior roles.
Built to pass detection
Banned phrase enforcement, burstiness control, and strict opening rules mean the output doesn't have the uniform rhythm that triggers AI detectors. The goal is letters that pass because they sound human — not because they game a specific tool.
The team
BlitzLetter is currently a solo project. No VC money, no growth team, no dark patterns — just a tool that does one thing well.
