Resume.io and Zety allow free builds but only export as plain TXT with formatting stripped. Teal also stands out with unlimited free PDF and Word downloads.</p> </div> </details> <details class="qa" id="ats-optimization" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <summary itemprop="name">How do these AI resume APIs handle ATS optimization differently?</summary> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"> <p itemprop="text">Rezi uses a live "Rezi Score" that evaluates resumes against ATS criteria in real time. Zety has a built-in ATS checker that flags keyword gaps as you build. Resume.io relies on recruiter-tested templates designed to pass screening. PitchMeAI dynamically extracts role-specific keywords from each job description before generating the resume.</p> </div> </details> <details class="qa" id="billing-concerns" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <summary itemprop="name">Are there billing transparency issues with Resume.io or Zety?</summary> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"> <p itemprop="text">Yes. User reviews in early 2026 consistently praise both platforms for output quality but criticize their pricing transparency. Resume.io's $2.95 trial auto-renews at $29.95 every four weeks, and Zety's $1.95 trial converts to $25.95 recurring charges. Multiple users report difficulty cancelling subscriptions on both platforms.</p> </div> </details> <details class="qa" id="developer-api" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <summary itemprop="name">Can developers build their own AI resume generation using APIs?</summary> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"> <p itemprop="text">Yes. Most consumer resume platforms are not API-first services, but developers can replicate similar functionality using OpenAI's GPT models with custom prompts or Google's Gemini API by sending structured candidate data as JSON alongside a target job description. Output can then be formatted into PDF or DOCX using document generation libraries.</p> </div> </details> <details class="qa" id="pitchmeai-difference" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <summary itemprop="name">What makes PitchMeAI different from traditional AI resume builders?</summary> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"> <p itemprop="text">PitchMeAI goes beyond document creation by automating the entire job application workflow. At $22/month, it personalizes resumes for each role, applies on your behalf, identifies hiring managers, finds their emails, and drafts personalized outreach messages. Users report up to 3x more interviews compared to manual applications.</p> </div> </details> </section>
