Craftly AI

🚀 Inspiration

The modern job market demands highly tailored applications, but customizing resumes and cover letters for every single job posting is incredibly time-consuming and often repetitive. We were inspired to leverage the power of artificial intelligence to automate this tedious process, empowering job seekers to create compelling, personalized applications in seconds. Our goal was to build a solution that is not only intelligent but also cost-effective, secure, and fully transparent through open-source principles.

💡 What It Does

Craftly AI is an intelligent web application designed to streamline the job application process:

• AI-Powered Resume Parsing
  Upload your resume in PDF, DOC, DOCX, or TXT format. Our AI (Google Gemini) intelligently extracts key details: contact info, skills, work experience, education, and summary.

• Personalized Cover Letter Generation
  Provide a job description and your resume — the AI crafts a unique cover letter tailored to the specific role and company.

• Secure Data Storage
  All user data is securely stored in a private Supabase database to ensure privacy and full control.

• Customizable AI Prompts
  Users can create and manage custom prompt templates to control the AI's tone, focus, and format.

• Flexible AI Model Integration
  Supports Google Gemini, OpenAI GPT, Anthropic Claude, and even custom endpoints.

• Rich Text Editing & PDF Export
  Refine generated cover letters with a built-in editor and export them as polished PDFs.

• Progressive Web App (PWA)
  Work offline, install on your device, and enjoy fast performance with native-like UX.
