Cover letter writing guide
What is an AI cover letter builder?
An AI cover letter builder gives you a useful starting structure for a job application. It can help you move from a blank page to a draft with a role-specific opening, relevant evidence, and a professional close. GrammarBuddy's builder is designed to support that process: start with the copyable template, replace the bracketed prompts with your own details, and then review the language before you send it. The goal is a clear, credible application—not a generic letter that could belong to anyone.
How to use the Cover Letter Builder
- 1. Start with the template. Sign in from the builder to open the copyable starter draft.
- 2. Replace every placeholder. Add the job title, company name, relevant experience, skills, and a specific reason you are interested.
- 3. Add evidence. Explain what you did and what changed, such as a process you improved, a customer you supported, or a result you helped deliver.
- 4. Polish and check. Use the Email Improver to review tone and clarity, then use the Grammar Checker for a final sentence-level check.
When a cover letter builder is useful
A guided draft is especially useful when you are applying for a role in a new industry, writing in English as an additional language, responding to a short job advertisement, or adapting one application for several related roles. It can also help fresh graduates organise internship, project, volunteer, or coursework evidence without pretending to have experience they do not have.
What should a cover letter include?
- A direct opening that names the role and gives a genuine reason for applying.
- One or two examples that connect your experience to the employer's needs.
- Specific details, such as the task, action, tool, customer, or result involved.
- A concise closing that thanks the reader and invites a conversation.
Short cover letter example

Dear Ms Tan,
I am applying for the Operations Executive role at Northstar Services. My experience coordinating customer requests and updating internal trackers has taught me how to keep details accurate while working across teams.
During my internship, I reorganised the weekly handover sheet and clarified ownership for open items. This made it easier for the team to see the next action and follow up with customers. I would welcome the opportunity to bring the same practical, organised approach to Northstar Services.
Thank you for considering my application. I would be pleased to discuss how my experience could support your operations team.
Yours sincerely,
Aisha Lim
Common cover letter mistakes
- Opening with a vague sentence that could fit any company or job.
- Repeating the CV instead of explaining why one experience matters for this role.
- Using inflated claims, unexplained jargon, or achievements you cannot support.
- Leaving placeholders, company names, or the wrong job title in the final version.
Frequently asked questions
What is an AI cover letter builder?
It is a writing assistant that helps you shape a cover letter around a role, your evidence, and a clear next step. GrammarBuddy provides a starter template and helps polish the wording; you still need to add your own facts and examples.
Do I need to sign in to use the Cover Letter Builder?
The Start Free and starter-template flow currently sends you to sign in before opening the copyable starter template. You can then edit the draft and send it to the Email Improver for a final pass.
How long should my cover letter be?
Aim for one focused page. Use a short introduction, one or two paragraphs of relevant evidence, and a closing that makes the next step clear.
Can a cover letter builder guarantee an interview or a job?
No. A builder can help you present your experience clearly, but hiring decisions depend on the role, employer, application, and your qualifications.
