Hmmm. Do we have to do a study of that? The AQI around LHR was 3 when I went there last year. Then realized all gas cars are banned at the airport.

Show HN: AI-powered cover letter generator based on resume and job description

Mikasa1 — Thu, 07 Aug 2025 18:26:10 +0000

Hi HN! I built PayRankJobs(https://payrankjobs.ai), an AI job matching service, and one of the most popular features has been the automated cover letter generation.

Here's how it works: • Upload your PDF resume once • AI extracts your skills, experience, and background • Click "Create Cover Letter" on any job match in your email • An LLM analyzes both your profile AND the specific job description. • Generates a personalized cover letter tailored to that exact role • Emails it to you

What makes it different from generic cover letter tools: - Uses your actual resume data (not templates) - Analyzes the specific job posting requirements - Matches your background to role needs - Avoids generic "I'm perfect for this" language

The system has generated 500+ cover letters so far.

Tech stack: Cloudflare Workers, OpenAI o3, PostgreSQL with pgvector, queue-based architecture for reliability.

Try it: Upload a resume at https://payrankjobs.ai and you'll get job matches with cover letter options.

Would love feedback on the AI prompting approach or the overall UX!

Show HN: PayRankJobs – AI matches your resume with the highest-paying jobs

Mikasa1 — Mon, 28 Jul 2025 12:47:16 +0000

Hi HN! Solo founder here. Built PayRankJobs (https://payrankjobs.com) after my (tech writer) wife kept getting spammed with $55K job "opportunities" when she's already making $200K.

What it does: - Upload your resume.

  - Set your minimum salary requirement (optional).

  - Get an email with personalized job matches that actually pay well.

  - Includes AI-researched salary data (base + equity) and company ratings

Technical stack: - Serverless on Cloudflare Workers

  - LLM for resume parsing

  - LLM for embeddings/matching

  - PostgreSQL + pgvector for similarity search

  - Dynamic job fetching via Google.

Key differentiator: Instead of browsing endless job boards, the system finds YOU the highest-paying roles. No more wasting time on jobs that don't meet your salary requirements.

Currently works for all english speaking countries (not just US) and provides salaries in local currency.

I haven't figured out monetization yet - currently burning through my own money on API costs. Would love ideas on this. Some thoughts:

  - Charge job seekers after X matches?

  - Recruiting/sourcing tool for companies?

  - Premium features (more frequent updates, salary negotiation tips)?

I'd love feedback on:

  - The onboarding experience

  - Email format/content

  - What other features would be valuable?

Happy to answer any questions about the implementation.
