1. GPT-4o Job-Tailored Cover Letter Generation

For each job, GPT-4o receives the full job description, the candidate's background profile, and the company's web presence context — generating a cover letter that specifically addresses the job requirements, uses the company's language from the posting, and highlights the most relevant candidate experience. Each letter is genuinely unique, not a template with blanks filled.

2. ATS-Specific Form Automation

Major ATS platforms (Greenhouse, Lever, Workday, iCIMS) have completely different form structures. The extension includes ATS-specific adapters for each — detecting which ATS is being used from URL patterns and meta tags, then applying the correct form automation strategy. Multi-step forms with progress indicators are handled with state persistence between steps.

3. Custom ATS Question AI Responses

Many applications include "additional questions" (e.g., "Why do you want to work at our company?", "Describe a time you overcame a challenge"). The extension extracts these questions and uses GPT-4o to generate contextually appropriate, candidate-voice answers — drawing from the configured candidate profile and the specific company context.

4. Adaptive Rate-Limiting & Cooldown Circuit Breaker

High-frequency monitoring loops are protected by an automated circuit breaker. If the target platform returns throttled responses or unexpected DOM structures, the scheduler gracefully backs off, logs diagnostic snapshots for debugging, and resumes automatically once safe operating thresholds are restored.
