The more detail the job listing includes - responsibilities, required skills, company context - the more precisely the tool can tailor your CV. Leave the output language on Same as the job description, or pick one of nine languages. 3. **Click Enhance My CV & Write Cover Letter.** Claude Sonnet analyses both documents, rewrites your CV to highlight the most relevant experience, and generates a personalised cover letter for the role. 4. **Review your results.** You will receive a tailored CV, a cover letter, a suitability score out of 10, a list of any skills gaps to address, and a set of likely interview questions with suggested answers. 5. **Download your documents.** as Word or PDF files. Use the role-fit finder to discover other roles that suit your background, and the job board search to apply directly. ## Key Points - **ATS-optimised output.** The tailored CV is structured to pass [Applicant Tracking Systems](https://www.jobscan.co/applicant-tracking-systems) used by most large employers. Keywords from the job description are incorporated naturally rather than stuffed artificially. - **Cover letter included.** Rather than a generic template, the cover letter is written using your real background and the specific role requirements. It reads as a genuine application, not filler. - **Suitability score and skills gap analysis.** A match score out of 10 shows how well your CV aligns with the role, alongside a clear list of any skills or experience the employer is asking for that your CV does not currently demonstrate. - **Interview preparation included.** The tool generates likely interview questions based on the job description and your CV, along with suggested answers drawn from your own experience - useful for preparation without starting from scratch. - **Role-fit finder.** Not sure what jobs to apply for? Upload your CV and click Find My Best Roles - Claude will return your top ten best-fit job titles based on your skills and experience. ## Frequently Asked Questions ### Which AI model does this tool use? The tool uses [Claude Sonnet by Anthropic](https://www.anthropic.com/claude) - specifically Claude Sonnet 5.5 (`claude-sonnet-5-5`). Sonnet is a more capable model than Claude Haiku and was chosen here because tailoring professional documents to specific roles requires stronger reasoning and instruction-following than simpler tasks. ### Is my CV stored or shared? No. Your CV and job description are sent to Anthropic's API to process your request only. Anthropic does not use API inputs to train its models by default, and JohnB.io does not log, store or share the content you submit. See the [Anthropic Privacy Policy](https://www.anthropic.com/legal/privacy) for full details. Do not include highly sensitive personal information such as passport numbers, national insurance numbers or financial details. ### What file formats can I upload? The tool accepts PDF, DOCX and TXT files. PDF and DOCX are recommended for preserving formatting. The text content is extracted on upload - embedded images and complex tables may not transfer perfectly, so check the extracted text before submitting. ### Can it write my CV in another language? Yes. Choose an output language under the job description: English, Italian, Spanish, French, Portuguese (Brazil or Portugal), Romanian, German or Bulgarian. The default, Same as the job description, matches the language the job advert is written in, so a Spanish advert gets a Spanish CV, cover letter and interview prep. Company names and qualification titles are kept as they are, and the PDF download supports accented letters and Cyrillic. ### How good is the tailored CV at beating ATS screening? The output is designed to incorporate relevant keywords from the job description in a natural way, which improves ATS pass rates. However, every employer configures their ATS differently. Tools like [Jobscan](https://www.jobscan.co) can give you a more precise match score for a specific ATS. Use the AI output as a strong starting point, then review it yourself before applying. ### What is the daily usage limit? The tool allows up to 20 enhancements per day per user. This limit applies per IP address and resets at midnight UTC.
