Tailoring a resume for every job is slow, and AI tools love inventing skills you don't have. ResumGula fixes both. Upload your resume, paste the job description, and get a prompt to run in ChatGPT, Claude or Gemini. Paste the reply back for an ATS-friendly PDF or Word resume plus a matching cover letter. Every line stays tied to your real experience, matched keywords are highlighted, and gaps are flagged honestly. No account, no uploads — everything runs in your browser.
