Giving candidates an unfair advantage in the modern job market.
Rattle-Snake CIA is a high-performance, open-source workstation designed to treat the job hunt like a tactical operation. It provides a suite of automated intelligence tools to tailor resumes, script cover letters, and map out interview strategies—all running locally in your browser for total privacy.
- The Iterative Scoring Loop: Don't just generate; optimize. If your ATS score is below 70%, the assistant triggers an "Improvement Pass," analyzing gaps in the previous output and re-injecting missing keywords until you hit the target.
- Section Locking: Protect your "Gold Standard" content. Toggle specific sections to remain untouched while the AI rewrites the rest.
- Diff-View Validation: Review every AI-suggested change with a side-by-side line-by-line diff viewer before accepting.
- Snapshot Versioning: Every accepted generation is saved as a numbered version. Experiment freely and roll back to any previous iteration instantly.
- Multi-Format Export: High-fidelity PDF (hyperlink-enabled), ATS-safe DOCX, and clean TXT exports.
- Four Tactical Styles: Generate letters optimized for Standard applications, Career Changes, Referrals (auto-mentioning contacts), or Cold Outreach.
- Streaming UI: Watch the AI build your pitch in real-time with an inline editor for final polishing.
- Linked Context: Directly link generated letters to specific tracked applications in your pipeline.
- The Prep Plan Builder: Parallel AI calls generate a triple-threat strategy:
- Skill Map: Identification of Core vs. Supporting requirements.
- Topic Pipeline: Prioritized question sets and frameworks (High/Med/Low difficulty).
- Practice Projects: Three custom project ideas designed to demonstrate your specific expertise.
- Humanized Q&A: Feed the assistant specific application questions; it uses your "Story Bio" to generate authentic, non-generic responses that sound like you, not a bot.
- Pin the Target: Set your target company and role once in the sidebar. This "Active Context" automatically propagates across the Resume, Cover Letter, and Interview modules, eliminating repetitive copy-pasting.
- Full-Featured Kanban: Manage your pipeline through 6 tactical stages:
Wishlist→Applied→Phone Screen→Interview→Offer→Rejected
- Application Spreadsheet: A sortable, filterable table view for deep-dive analysis and CSV export of your entire search history.
