Job title + company name + the full job description (paste it), your resume (paste it), and optional "why this company" context. The AI cross-references the JD against your resume and drafts a 250-350 word letter that emphasizes only skills and experiences you actually have. Nothing invented.
Kickresume and Resume.io bundle cover-letter generation into paid subscriptions ($16-28/mo) and tend to produce generic boilerplate that ignores the JD. LinkedIn's AI cover letter (Premium only, $30/mo) writes from your profile but does not see the JD. Free.ai reads the JD and your resume side-by-side and matches specific bullets — that's the whole game for cover letters.
No. The system prompt explicitly forbids claiming skills, tools, certifications, job titles, or companies not present in your resume. If the JD asks for Kubernetes and your resume only shows Docker, the letter writes "containerization experience including Docker" rather than inventing Kubernetes. If the JD requires something completely absent from your resume, the letter acknowledges it honestly ("While I have not used X, my work with Y...") rather than faking it.
Very. The AI picks 2-3 specific bullet points from the JD and maps each to a matching bullet in your resume, writing a short story paragraph ("At Acme, I built X which solved Y — exactly the challenge your team is describing for role Z"). If your resume has nothing to match a JD bullet, the AI either skips it or writes honestly around it.
Edit it first, always. AI cover letters still have telltale rhythm that experienced recruiters spot. Cut any sentence that sounds AI-generic ("I am thrilled to apply..."), replace it with your own voice. Keep the JD-matching bullets the AI structured — those are the revenue part. Hand-editing takes 10 minutes instead of 45.
Default opener is NOT "I am writing to express my strong interest" (which every recruiter's eye-skip blocks). Free.ai opens with a specific hook: either a 1-line result ("Last year I migrated 40 SKUs to Shopify Plus, cutting checkout friction 18%"), a shared company detail ("Your recent launch of Product X caught my attention because..."), or a direct match ("Your JD's bullet on 'reducing payroll errors' describes exactly the system I built at..."). Customize in the "hook" field.
One page max — 250-400 words, 3-4 paragraphs. Anything longer, recruiters skim. The AI defaults to 300 words which fits cleanly on a single page with standard margins and 11-pt Times / Calibri.
Yes — paste the same resume but different JDs and the AI outputs letters tailored to each. Many job seekers apply to 20+ jobs a week; Free.ai turns cover letters from a 45-minute chore per role into 2 minutes + a 10-minute edit pass.
Free Qwen 3 30B handles most cover letters well. For senior roles (Director+, C-suite, Principal IC), upgrade to Claude Sonnet or GPT-5 — the tone polish on executive letters is worth the premium tokens.
Yes — UK and Commonwealth (slightly more formal, "Dear Sir/Madam" still OK), German (structured with "Sehr geehrte/r..." and a short paragraph format), French ("Madame, Monsieur," with "Je vous prie d'agréer..." closing). Specify the country/language in the hook field and the AI adjusts conventions.
Plain text (paste into LinkedIn / Indeed / Greenhouse), markdown, or a minimal ATS-safe .docx. If the company wants a PDF, export .docx and Save As PDF from Word / Google Docs. Skip Canva / fancy templates — recruiters strip them anyway.
Generation records store a 200-char preview + the output. Delete anytime at /account/?tab=history. For maximum privacy, pick Qwen 7B (never leaves our GPUs) over premium models (which route through the provider's API).
