A letter written for one specific role, from your real experience.
Dear Stripe Hiring Team,
I'm applying for the Senior Frontend Engineer role on the Dashboard team. For six years I've built data-heavy React and TypeScript interfaces, most recently leading a checkout rebuild at a fintech scale-up that cut time-to-interactive by 2.1 seconds and lifted paid conversion by 14%.
Three things I'd bring:
- A design system used by 40+ engineers across five product teams.
- Performance budgets for Core Web Vitals, enforced in CI.
- Accessibility by default: my last three products shipped WCAG 2.1 AA from day one.
The Dashboard is the product I point teammates to when we argue about quality. I'd love to help raise that bar, especially in payment flows where clarity moves revenue.
Best regards,
Alex Carter
What makes a cover letter get read
Recruiters skim. A cover letter earns a second look when its first lines show you read the posting: name the role, then lead with one result that matches what they asked for. Numbers help. “Cut time-to-interactive by 2.1 seconds” lands where “improved performance” doesn't.
Keep it to three or four short paragraphs. Mirror two or three of the posting's key phrases where they are honestly true of you. Close with why this company, in a sentence you couldn't send to anyone else.
The generator does this from what you paste: it picks your strongest matching results, uses the posting's vocabulary, and keeps to the facts in your résumé. Read it once before you send it. You know details about your work that a résumé never shows.

Questions
How is this different from a template?
Templates fill in blanks. The generator reads the posting and your résumé, picks the experience that fits this role, and writes the letter around it.
Is it really free?
Yes. Each tool gives you one free run, with no sign-up and no credit card. After that, a free JobCubby account gives you 15 AI generations a month.
Do you store my résumé or the job description?
No. JobCubby doesn't store the text you paste here. It is sent to our AI provider only to produce your result, and JobCubby doesn't keep it. We keep a count of runs (without your text) so each tool stays one free try.
Can I change the tone?
Yes. Pick Professional, Warm or Direct before you run it. In a free account you can also set the length, add your own instructions, and regenerate.
Why do you check that I'm human?
The free tools run on real AI, so we use Cloudflare Turnstile to keep bots from using them up. It usually passes on its own without a puzzle.
