Job title: Customer Success Manager Company: Northwind Logistics Experience: 4 years in support at a SaaS company. Led onboarding for 40 mid-size accounts. Wrote the help-centre articles for the billing module. Cut average first response time from 12 hours to 4 by introducing a triage rota.
Letter (excerpt)
Dear [Hiring manager's name], I am writing to apply for the Customer Success Manager role at Northwind Logistics. Over four years in support at a SaaS company, I led onboarding for 40 mid-size accounts and cut average first response time from 12 hours to 4 by introducing a triage rota. I also wrote the help-centre articles for our billing module, which taught me to explain complex processes simply. I would bring that same focus on clear communication to your customers. I would welcome the chance to discuss how my experience fits your team. Sincerely, [Your name]
Every figure comes from the notes. Nothing about Northwind itself is invented, so add a line of your own about why you want to work there.

Letter (excerpt)
Dear [Hiring manager's name], I am applying for the Project Coordinator position at Brightside Housing. After six years as a secondary maths teacher, I am moving into coordination work that draws on skills I use every day: planning, organising and communicating clearly with many people. I ran the department timetable for eight teachers and organised two school trips, which meant managing schedules, deadlines and expectations. I am confident with spreadsheets and experienced in keeping parents informed. I would be glad to talk about how these skills transfer to your projects. Sincerely, [Your name]
The tool bridges the two worlds using only what you listed. Add why you are changing careers in your own words.
Thin notes, honest output
What you enter
Job title: Marketing Assistant Company: Fernlight Experience: Recent graduate. Interested in social media.
What you get
A short, general letter that states your interest and degree status, with placeholders such as [your degree and subject], [a relevant project or placeholder example] and [a reason you like Fernlight]. It does not invent internships, results or skills.
Thin input gives a thin letter by design. Add one project, one result and one reason and rerun.
How to generate a cover letter
Enter the role and company
Use the exact job title from the posting and the company name. These go straight into the letter.
Paste the job description and your experience
The job description is optional but gives the best results because the letter then lines up with what the employer asked for. For your experience, list roles, projects, tools and real results. Rough bullet notes are fine.
Edit it until it is yours
Fill the [placeholders] for names, check every claim is true, and rewrite any line that does not sound like you. A letter you have edited is better than any first draft.
What to put in, to get a letter worth sending
The generator writes only from what you give it. It is instructed not to invent employers, numbers, degrees or achievements. That keeps the letter honest, and it means the quality of the output depends on your notes.
- Experience that matches the job. Pick the two or three things most relevant to this role rather than pasting your whole career.
- Results, in your own numbers. "Reduced average response time from 12 hours to 4" is much stronger than "improved support". Only use figures you can stand behind.
- The job description. Paste the full posting. The letter will pick up the language of the requirements and answer the ones you can.
If something relevant is missing, you will see it: gaps appear as [placeholders] or generic phrasing, not made-up detail.
What a good cover letter does
A cover letter is not a restatement of your resume. It answers a recruiter's question: why this person, for this role, here? A solid one does four things in about 300 words.
- Opens with the role and a specific reason you want it.
- Connects one or two of your best experiences to what the job needs.
- Shows you know something about the company, which you may need to add yourself.
- Closes with a clear next step.
The tool follows this shape. Its limit is that it only knows what you told it about the company. Add a sentence of your own about why you want to work there, and the letter will read as written by a person.
Cover letter, resume and ATS
Many employers use an applicant tracking system, and the resume does most of the filtering. The 12 resume mistakes that get you filtered out by ATS guide covers the common ones. Use the same keywords from the job posting in both documents, as long as they honestly describe your experience.
Run your resume through the resume checker against the target role, then use this tool for the letter. If you are juggling an offer, the counter offer letter generator is the next step, and if you are leaving a job, there is a resignation letter generator.
Using AI on applications, honestly
Using AI to draft a letter is common, and employers' attitudes vary. Some ask about it, a few ask you not to, and recruiters notice generic letters regardless of who or what wrote them. Three habits keep you safe and keep the letter good:
- Every claim must be true and something you can talk about in an interview.
- Rewrite the opening and closing in your own words.
- Follow any instruction in the posting about AI use.
If an automated system rejected your application, you may have more rights than you think; see the guide on what to do when an AI rejects your job application.
Polish it in the extension
Once you have a draft, the Copilotly extension can tighten it wherever you paste it, for example in an application form or a Google Doc. Use the tone and length pickers to shorten a paragraph, and the word-by-word comparison to see what changed. The tone changer on this site does the same for a single block of text. Install for Chrome, Edge or Firefox.
Cover letter questions, answered
How long should a cover letter be?
About one page. The tool aims for 250 to 350 words, which fits comfortably, and the Purdue OWL guide describes the same one-page, focused shape.
Do I still need a cover letter?
If the posting asks for one, yes. If it is optional, a short, specific letter can help you stand out, and a generic one will not. When in doubt, include one that actually answers why you want this role.
What should I never include?
Anything untrue, anything you could not explain in an interview, and sensitive details the employer does not need. The tool uses only what you give it, so what you give it is your responsibility.
How do I use the job description well?
Paste all of it, then check that the two or three main requirements are answered by your experience. Use the same vocabulary the posting does when it truthfully describes what you did. The ATS resume guide explains why wording matters.
Before you send it
| Check | Why |
|---|---|
| Every [placeholder] replaced | An unfilled bracket is the quickest way to look careless |
| Company and job title correct | Copy them exactly from the posting |
| Every number is yours and true | You will be asked about it |
| One sentence about why this company | The tool cannot know your reason |
| File name and format | Follow the posting's instructions |
Pair it with a checked resume
A letter and a resume should tell the same story. Run your resume through the resume checker against the posting before you apply.
Use the right channel for the follow-up
After applying, a short follow-up can help. The email writer drafts one from a brief. When an offer arrives, the counter offer letter generator is the next step.
Know your rights if a system rejects you
Many employers screen applications with automated tools. See the guide to what to do when an AI rejects your application.
Making the paragraphs yours
The opening
Replace the first sentence with the real reason you want this job. "I am excited to apply" is what everyone writes. "I have spent four years on onboarding and your role is the same problem at larger scale" is yours.
The middle
Keep the strongest one or two examples and cut the rest. Check that each has a number, a name or an outcome you can talk about in an interview.
The close
One clear next step, in your words: you are available to talk, and when. Then your name. Be polite, brief and specific.
Tone
If the draft is too stiff or too eager, the tone changer can move it to Professional or Confident. Keep the facts exactly as you wrote them.
Who it is for
Career changers
List the transferable parts of your experience, not job titles: planning, budgets, customers, deadlines, tools. Paste the posting so the letter answers its requirements. Then add a sentence of your own that says why you are changing direction. The career pivot guide covers how to frame it.
Recent graduates
Use coursework, projects, volunteering and part-time jobs, with real numbers where you have them. If you have little to say, the tool will tell you with placeholders instead of invention. Fill those honestly and keep the letter short. Cover letter basics are in the Purdue OWL guide.
People applying to many roles
Keep one notes file of your best experiences and results. For each application, paste the new posting and company, take the draft and change the opening. Tailoring beats volume: a letter that matches the job is more use than five generic ones. Run your resume through the resume checker for the same role.
People returning after a break
Lead with relevant skills and recent activity such as courses, volunteering or freelance work, and decide how much to say about the gap. You do not have to explain it at length. The tool only states what you tell it, so you control that message. Tone matters here, so the tone changer can help it sound confident.
What to put in each field
| Field | Required | Limit | Tip |
|---|---|---|---|
| Job title | Yes | 300 characters | Copy it exactly from the posting |
| Company | Yes | 300 characters | Used for the greeting and closing |
| Job description | No | 6,000 characters | Paste it for a tailored letter |
| Your experience | Yes | 6,000 characters | Roles, projects, results you can verify |
If something goes wrong
The letter is generic
It had little to work with. Paste the full job description and add two or three specific results to your experience, then run again. Generic input produces generic output because the tool will not invent detail.
It has placeholders I cannot fill, such as the hiring manager's name
Check the posting, the company's site or LinkedIn for a name. If you cannot find one, "Dear Hiring Team" is a normal alternative. Replace every bracket before you send.
The letter is too long for the application
Paste it into the paraphrasing tool in Shorter mode, or cut the weakest paragraph by hand.
It sounds like AI
Rewrite the opening and closing lines in your own words, add one specific detail only you would know, and read it aloud. Some employers ask applicants about AI use, so follow any instruction in the posting.
I hit the daily limit
The free allowance is a few runs per visitor per day. A free Copilotly account gives you more, plus the extension.

12 Resume Mistakes That Get You Filtered Out by ATS (and How to Fix Each One)
75% of resumes are filtered out before a human ever reads them, usually for fixable formatting and keyword problems.

An AI Rejected Your Job Application. Here Is What You Can Actually Demand.
Almost everything written about AI hiring laws is aimed at employers trying to comply. Almost nothing is written for the person on the other side of the rejection. Depending on where you applied, you may have a legal right to be told an algorithm was used, to correct the data behind it, and in some cases to have a human look again. Here is what exists today, what arrives in 2027, and the exact language to use.
The 90-Day Career Change Plan for Mid-Career Professionals
Nearly 7 in 10 workers say they want to change careers, but most stall without a structured plan. This 90-day framework moves through skills inventory, targeting AI-resilient industries, bridge-building, and resume repositioning, with data on the 25-40% salary premium AI literacy now commands.
How to Ask for a Raise: Word-for-Word Scripts and Email Templates
Only 39% of workers negotiate their salary, and skipping it costs an average of $7,500 per job, over $600,000 across a career. These word-for-word scripts and email templates cover asking for a raise, countering a new offer, and pushing past 'final offer'.
Common questions
Is this cover letter generator free?
Yes. A few runs a day, no account, no card. The free Copilotly account gives you more runs and the extension.
Will it make up experience or achievements?
It is told to use only the experience you provide, and not to invent employers, numbers, degrees or achievements. Still read the letter and remove anything that is not strictly true.
How long is the letter?
About 250 to 350 words, which is a standard length for a one-page cover letter. Use the paraphrasing tool in Shorter mode if you need it tighter.
Do I need to paste the job description?
No, but it helps. With it, the letter is aligned to the requirements. Without it, you get a more general letter for the role and company you named.
Is this Microsoft Copilot or a Microsoft product?
No. Copilotly is independent and not affiliated with Microsoft. Its tools run in your browser and on the web.
Does it fill in my name and the recruiter's name?
It uses [bracketed placeholders] for names, because it does not know them. Fill them in before you send.
Can employers tell if I used AI for my cover letter?
Sometimes, because generic letters stand out whoever writes them. Some employers ask about AI use and a few prohibit it, so follow the posting. Add specifics only you know and rewrite the opening and closing in your own words.
