Building a Resume-Job Matcher with Claude
Bridge_Corp · reddit · 2026-07-13
The author built a Chrome extension named CV Align using the Claude API to match resumes with job descriptions.
What the Product Does
- After pasting a JD into the sidebar, Claude analyzes your saved CV
- Outputs a match score with text explanations
- Categorizes into: strong matches, actual gaps, and partial matches
- Identifies preference conflicts (e.g., you prefer remote work, but the job requires 4 days in-office)
- Supports uploading portfolios, certificates, and recommendation letters for unified analysis
- Paid users can generate tailored CVs and cover letters, exporting them as Word docs
Why Claude?
The author finds Claude's structured output highly stable for JSON returns. Additionally, its writing style is more natural, avoiding hollow, template-like application materials.
Technical Architecture
- The system prompt restricts the AI to only use info from the CV and attachments—no fabrication allowed
- CV, JD, and preference data are isolated using XML tags
- Output is strict JSON containing matches, gaps, partials, and preference flags
- All generated content must be traceable to source documents
Pricing
- Free tier: 5 analyses per month
- Paid tier: £4.99/month for 60 analyses and 40 document generations
The author invites further discussion for anyone interested in the prompt structure or architecture.
