Cover Letter: How to Write a Letter with AI
A cover letter often decides whether your resume gets opened. The 'Cover Letter Writer' tool helps create a draft that connects your real experience to a specific vacancy. It is not an autopilot: you provide the source data, get text and check it. In this guide we will walk through how to prepare the input, run the task and verify the result against specific criteria. Examples are fictional and provided for illustration.
Open tool: Cover letter writer ↗What the Tool Does and Does Not Do
'Cover Letter Writer' is a web form with two text fields: 'Source Material' and 'Role or Characters'. You fill them in, select the output language, press Generate and get one result in a separate panel. It can be copied or downloaded as a plain text TXT file. There are no style presets, sliders or change levels. It is important to understand: you are not setting the tone, you are just describing facts.
The tool cannot export to DOCX or PDF, does not perform batch processing, does not save history automatically, does not integrate with job sites and does not send emails by itself. It also does not upload documents or perform OCR on images. Everything you get is a draft in plain text form. You will have to edit it manually.
The model may make mistakes: confuse facts, add unnecessary details or use overly generic phrases. Therefore the result always needs checking. The tool does not guarantee that you will be invited for an interview and does not replace your own judgment about what is appropriate for a specific company.
Example request: in the 'Source Material' field — 'Two years in retail, working with a cashier, basic Excel, helping customers'. In the 'Role or Characters' field — 'Electronics store sales consultant'.
How to Prepare the Source Material
The first field accepts up to 8000 characters, but do not fill it with everything at once. Collect only facts that relate to the vacancy: where you worked, what you did, what results you achieved, what tools you used. For example, if the job requires working with clients, write how many clients you served per day and how you resolved conflicts. If table work is needed, specify exactly what you did in Excel.
Avoid generic words like 'responsible' or 'communicative' — they can go in a resume but for a letter you need specific examples. Instead of 'worked in a team' write 'coordinated work of three people during inventory'. The more precise the source data, the less the tool will have to guess for you.
If your experience is limited, describe academic projects, volunteering or courses. For example: 'Completed a basic Excel course, created a table for tracking family expenses'. This is also real experience and can be linked to the vacancy. The main rule — do not invent what was not there.
Good source material: 'Worked as a salesperson for two years. Served up to 50 customers a day. Helped choose goods, worked at the cashier, processed returns. Kept a stock table in Excel. Replaced the senior salesperson during vacation'.
How to Describe the Role or Characters
The second field — 'Role or Characters' — accepts up to 1000 characters. Here you need to state the position you are applying for and, if known, the company. For example: 'Electronics store sales consultant, Company X'. If the company name is unknown, describe the field: 'Small web design studio looking for an administrative assistant'.
Do not retell the whole vacancy. It is enough to give the role name and key requirements. The tool uses this to connect your experience with the employer's expectations. If you specify too general a role, e.g. 'manager', the letter will be blurred. Better specify: 'Customer manager in an online school'.
If the vacancy requires specific tools, list them in this field. For example: 'Requires confident Excel and CRM use'. Then the tool can highlight corresponding experience from the first field. But do not copy the whole vacancy — this will distract the focus.
Field 'Role or Characters': 'Electronics store sales consultant. Requires cashier experience, Excel knowledge, ability to communicate with customers'.
Generation and Preliminary Check
After filling the fields select the output language and press Generate. The result appears in a separate panel. First read it through without editing. Note the structure: is there a greeting, a main body with examples and a closing? A good letter usually takes 3–4 paragraphs.
Check whether all key facts from the first field made it into the text. If you wrote about working with a cashier but the letter says nothing about it, the tool missed something. If details appear that you did not mention — this is an error, they must be deleted. For example, if it says 'increased sales by 20%', but you did not say that, such a detail cannot be kept.
Make sure the letter does not sound too template-like. Phrases like 'I am the ideal candidate' or 'I would be happy to discuss' are not bad on their own, but if there are too many the text loses individuality. Check that there is at least one specific example from your experience in the letter.
After generation you see: 'Hello! I was interested in the sales consultant vacancy. I have two years of retail experience, I served up to 50 customers a day and worked at the cashier. I also have basic Excel knowledge'. This is a good draft, but you need to check for unnecessary details.
Result Check Criteria
Check the letter against four criteria: relevance to the vacancy, specificity, tone and literacy. Relevance: are all requirements from the second field reflected? If the vacancy requires Excel but the letter only says 'working with tables', it is better to clarify. Specificity: are there numbers, tool names, task examples? Without them the letter looks generic.
The tone should be polite but not grovelling. Avoid phrases 'I will be the perfect employee' or 'You will not regret it'. Better say: 'My retail experience will help me get up to speed quickly'. Literacy: check spelling and punctuation. The tool may make mistakes, so reading the text aloud helps spot awkward phrases.
Separately check that there are no fabricated facts in the letter. The model sometimes adds 'experience at a large company' or 'Python knowledge' if you only mentioned Excel. All such insertions must be removed. The letter should contain only what you confirmed in the source data.
Criterion 'specificity': if the letter says 'able to work with large data volumes', this is too general. Better: 'Kept a stock table of 200 positions in Excel'.
Limitations and Typical Errors
The tool does not save history, does not export to DOCX or PDF and does not send emails. You can only copy the text or download TXT. If you need to send the letter, you will have to paste it manually into an email client or a job site. There is also no batch processing: each letter is generated separately.
The model can make mistakes, and queue and availability may change. Do not count on getting a perfect text on the first try. Sometimes it is useful to generate two or three variants, changing the source data, and choose the best one. But do not overdo it: too many options will confuse you.
Another mistake — indicating false information in the source data. If you write 'fluent English' but it is not true, the tool will insert it into the letter, and it will be awkward at the interview. Always verify that every fact corresponds to reality.
If you indicate '5 years sales experience' but you actually have 2, the letter will contain a lie. This can lead to rejection.
How to Adapt the Draft to Yourself
After checking edit the letter manually. Add a salutation by name if you know it. Remove template phrases that do not fit your situation. For example, if the company is small you can write: 'I like that you work with local manufacturers'. But this must be true.
Shorten the letter to 3–4 paragraphs. The first — greeting and vacancy mention. Second — your experience and specific examples. Third — why you are interested in this company. Fourth — closing with thanks. Do not retell the whole resume.
Make sure the letter does not duplicate the resume word for word. A cover letter is an opportunity to show motivation and connect experience to a specific vacancy. If the resume says 'worked with a cashier', in the letter you can add: 'I quickly learned the cashier program and helped new employees'.
Ready fragment: 'Hello Anna! I was interested in the sales consultant vacancy in your store. Two years I worked in retail, served up to 50 customers a day and learned the cashier program. I also confidently use Excel for stock tracking. Would be glad to discuss how my experience can be useful to your team'.
The 'Cover Letter Writer' tool is an assistant for creating a draft, not a ready solution. It saves time but requires your participation: precise source data, fact-checking and manual editing. Use it as a starting point, not as the final text. Remember the limitations: no DOCX export, no batch processing, the model may make mistakes. Always check that the letter matches the vacancy and does not contain fabrication. The examples in the article are fictional and provided for training. If you follow the steps you can quickly create personalized letters and increase your chances of a response.
