The problem

Applying for jobs is a tedious, repetitive process. Students and fresh graduates often rely on batch WhatsApp groups where opportunities are posted as unstructured text dumps. Manually extracting each job, finding the recruiter's email, and drafting personalized cover letters takes hours — and most candidates simply give up or send generic applications.

Applicator solves this by leveraging AI to analyze raw message dumps, identify every job opportunity, extract recruiter contact details, and generate tailored cover letters — all from a single paste.

Chat & Cover Letters

Paste WhatsApp messages and get instant AI analysis. Select any extracted job to generate a personalized cover letter tailored to your profile, skills, and uploaded CV.

AI Extraction Pipeline

The NVIDIA Build API runs Llama 3.1 8B instruct. Raw WhatsApp text is analyzed in batches to identify job positions, extract recruiter contact details, and match keywords against target roles.
