How it works

Five steps from job posting to interview-ready Word document. No template filling, no copy-pasting. Claude reads the JD and your resume, then builds a targeted document.

1
Paste the JD
Copy any job description. The agent reads the full text — requirements, preferred skills, company language.
→
2
Scores all versions
Claude scores each resume version (0–100) against the JD. Best match highlighted. Skill gaps surfaced as tags.
→
3
2 targeted questions
Specific, clickable questions — pre-filled with your actual bullets. One "Other" line per question. No forms.
→
4
Add role context
Expand any role to add context or additional accomplishments. Completely optional. Claude uses every word.
→
5
Download .docx
Resume builds in the browser via docx.js. One click downloads a formatted Word file. Ask for revisions in plain English.

What's under the hood

Built from scratch — no third-party resume tools, no templates. Every component was designed and deployed as a production system.

Anthropic Claude API
Multi-turn conversational session — Claude reads all resume versions, scores them, generates targeted questions, builds structured resume JSON, and writes revision updates on request.

Cloudflare Worker
Dedicated serverless Worker (job-agent.alex-b7b.workers.dev) — isolated from Solenetec, handles CORS, forwards the full messages array to Claude API with encrypted API key. Zero cold-start issues.
Workers (free tier)encrypted secretsCORS proxy
docx.js (client-side)
Word documents built entirely in the browser — no server, no file upload, no storage. Claude returns a resume JSON object; the frontend assembles a formatted .docx and triggers a direct download.

localStorage Persistence
Resume vault (4 versions), full session history with conversation threads, and theme preference all persist in localStorage. No login, no database. Vault is pre-loaded — only the JD needs to be pasted each session.

Single HTML File
The entire tool — UI, state management, API calls, document generation, history — ships as one HTML file. No npm, no build step, no framework. Deployable to any static host in 30 seconds.

Passphrase Protection
Simple JS passphrase check on load — no auth server, no accounts. The tool is publicly hosted but access-controlled. Designed for personal use while a full auth layer is built for Phase 2.

Phase 2 will open it as a commercial product with multi-user auth, Cloudflare KV storage, and PDF/DOCX vault upload.
