Generate a tailored cover letter from your resume and job description — 100% private, runs in your browser.
This tool runs 100% in your browser. All computation happens locally on your device — your input is never uploaded to any server. Results are for reference only.
A generic cover letter restates your resume; a tailored one reverse-engineers the job description. The tool cross-references every requirement in the JD against the evidence in your resume, finds the strongest skill overlaps, and writes a narrative that maps your concrete results onto each stated ask — "5+ years of React" becomes "five years shipping React at scale," backed by a metric. It then applies a tone profile (formal, conversational, enthusiastic, or concise) that controls greeting, pacing, and length, targeting a professional letter of under 300 words. The result is an editable first draft in which every claim is traceable back to a real resume fact.
The letter is built as a chain: JD requirements are matched to resume evidence, then rewritten into narrative beats. Nothing in the final letter is invented — every claim traces to a fact you supplied.
John Smith is applying for the Senior Frontend Engineer role at InnovateLab. His resume lists 5 years of React, a microservices migration that cut latency 40%, and managing a team of five engineers. He pastes both the resume and the JD and selects the formal tone.
To write a cover letter: paste the job description and your resume, the AI generates a tailored cover letter highlighting your relevant experience.

Generate a professional cover letter from your resume and job description. 4 tones. 100% private — AI runs in browser. No signup, free.
The AI Cover Letter Writer builds a letter that is specific to one job posting, not a generic template with the company name swapped in. You paste two things: the text of your resume and the job description you are targeting. A language model running locally in your browser studies both, pulls out the requirements that match your experience, and writes a letter that speaks to them directly. Four tone settings control the voice, from a traditional formal letter to something short and punchy. The output lands in an editor where you can rewrite any sentence, watch the word count, and download the finished letter as a plain text file.
Active job seekers applying to several roles a week use it to produce a genuinely tailored letter for each posting in a couple of minutes. Career changers rely on it to translate experience from one industry into the language of another, connecting old achievements to new requirements. Recent graduates, who often have thin cover letter experience, get a structural starting point instead of a blank page. Privacy-conscious applicants appreciate that their resume — full of phone numbers, employers, and dates — is processed on their own device rather than pasted into a chatbot or uploaded to a subscription service that stores it who knows where.
(1) Paste your resume text — any layout works, since the model reads plain text rather than parsing formatting. (2) Paste the job description for the role you want. (3) Pick a tone: Formal for corporate HR departments, Conversational for startups, Enthusiastic when you want energy to show, or Concise, which keeps the letter under 200 words for recruiters who skim. (4) Click Generate. The letter appears in an editable editor with live word and character counts. Revise anything — swap in the hiring manager's name, add a sentence about why this company specifically — then copy it or download it as cover-letter.txt. If the first version misses the mark, change the tone and regenerate.
Treat the generated draft as a strong first pass, not a final product. The letter is fully editable, so replace generic praise with specifics the AI could not know: the project you led, the metric you moved, the moment you decided you wanted this job. Recruiters consistently reward letters that name something real about the company, so add one researched sentence. Tone choice does heavy lifting too — the same resume reads earnest in Enthusiastic mode and brisk in Concise mode, and different companies respond to different registers. Because the AI model runs locally, generating three variations in three tones and stitching the best parts together costs you nothing but time.
Paste your resume (or key experience points) and the job description. The AI model (SmolLM2 running locally in your browser) extracts your relevant skills, achievements, and experience that match the job requirements, then generates a 3-paragraph cover letter referencing specific qualifications. Choose from 4 tones: professional, enthusiastic, concise, or narrative.
No. The AI model runs 100% in your browser via WebGPU/WASM. Your resume content and the job description are processed locally—no data is transmitted to any server. This is critical for privacy, as your resume contains personal contact information, employment history, and salary expectations.
