Resume & Thread: Local-First AI Resume Tailoring with Mastra & Google Gemma 2

Description and use

Resume & Thread is a local‑first resume tailoring tool that uses Google Gemma and Mastra to quickly and privately adapt resumes, boosting ATS scores from 54% to 96%.

Problem

Commercial resume optimization tools charge $20–$40/month and require uploading personal data to cloud servers, exposing privacy risks and producing generic keyword‑based resumes.

Outcome

Tailoring speed increased from 3–5 minutes to one click; ATS match score rose from 54% to 96% (+42%); all processing remains local with zero cloud leakage.

Workflow

• 1. User opens job board in Chrome
• 2. Extension scrapes job requirements
• 3. Popup sends job spec to local server (127.0.0.1:4141)
• 4. Server validates schema with Zod
• 5. Mastra DAG normalizes job spec
• 6. DAG analyzes skill delta
• 7. DAG adapts resume using Google Gemma 2 if Ollama available, otherwise AST fallback
• 8. DAG calculates ATS score
• 9. DAG synthesizes artifacts (PDF, Markdown)
• 10. User downloads tailored resume

Evidence

Commercial resume optimization tools charge job seekers $20 to $40 every month for superficial keyword matching.
