Cover Letter Generator

The one field that decides whether it works

"Why This Company" is marked optional. It is the most important box on the form, and here is the reason, stated plainly because no other tool in this category will.

The generator does not research the company. There is no lookup happening — it writes from what the model already knows plus what you type. For a household name that yields something passable. For a 250-person firm, a local agency or a startup nobody has written about, it produces warm generic praise that could be about any employer in the world.

And generic praise is exactly what makes a cover letter worthless. A recruiter has read "I am drawn to your commitment to innovation and excellence" several thousand times and it registers as nothing.

So spend two minutes before you generate. Look at the company's site, the job posting, a recent announcement, their product. Then put something concrete in that box: a product you have actually used, a specific problem the role clearly exists to solve, a detail from the posting that matches something you have done. One real sentence there changes the whole letter, because everything else is built around it.

Shorter than you think

Three lengths. Most people reach for the longest and should not.

Standard, three paragraphs, is the default and right for nearly everything: why this role, what you bring with evidence, and a close. Short, one paragraph, is genuinely good for an informal application, a small company, or pasting into a form field or an email body — and a tight paragraph that says something beats three that say nothing. Detailed, four to five paragraphs, is justified when you are changing career and the pivot needs explaining, or when the posting asks you to address specific criteria point by point. Otherwise it dilutes.

The reality is that most cover letters get a few seconds. A shorter letter is more likely to be read all the way through, which is the only outcome that matters.

Tone, and how to pick

Professional is the default and the safe choice — established companies, finance, law, government, anything where a formal register is expected. Enthusiastic suits startups, agencies, creative roles and any posting written in a conversational voice. Confident fits senior positions where the letter needs to assert what you would bring rather than ask to be considered.

A reasonable heuristic: read the job posting and match it. A posting written in plain, warm language and a stiff formal letter are a visible mismatch, and so is the reverse.

Then rewrite the opening line

Take whatever comes back as a draft, and pay special attention to the first sentence — it is the one that gets read, and generated openings tend toward the formulaic. If it begins by announcing that you are writing to apply for the position, replace it. The reader knows why you are writing.

Read the rest aloud. Anything you would not say in an interview should come out, because a letter that sounds nothing like you sets up an awkward first conversation. And check the details: the company name spelled correctly, the right job title, no sentence left over from the last application you sent.

What happens to what you type

Unlike the PDF and image tools on ToolsHall, this one is not browser-only — your inputs are sent to a language model to be written. You do not need to include your full name or contact details for the letter to work; those go on the finished document, which you are writing in your own editor anyway. Usage is capped at 30 runs an hour, which keeps it free without an account.
