The Why-This-Company Paragraph, Rewritten.
Same letter. Same claims, different phrasing.

The Last Read Before You Hit Send.
Paste the letter. See what the major detectors read in it. Rewrite the lines that sound like a template instead of like you.

Answers to what applicants ask us most.
Often, yes, because AI cover letters share a small set of openings and cadences that anyone reading a stack of applications starts to recognize. Detectors work on the same signals: even sentence length, hedged phrasing, stock transitions. Run the draft through the [AI detector](/ai-detector) first so you can see which lines carry those patterns before a human reads them.
Because models default to the safest opening in their training data, which is why so many letters start with a variation of writing to express interest in the role. The opening line is the first thing a hiring manager reads and the fastest place to lose them. Lunchbreak rewrites that line into plainer phrasing while keeping the role and company you named.
No. It rewrites phrasing only, and it will not invent a job, a title, a date, a credential or a result you did not earn. If your draft says you led a launch, the rewrite still says you led a launch. You remain responsible for the accuracy of every claim in the letter. Read the output before you send it and correct anything that no longer matches your record.
No. An applicant tracking system parses and ranks text, matching keywords and structure against a job description. It is not an AI detector and does not score writing for machine authorship. AI detection, when it happens, comes from a separate tool a recruiter chooses to run, or from a human noticing the pattern. Keep formatting simple for the parser and keep the phrasing your own for the reader.
Ask for the thing you actually want, in one short sentence, and cut the stock sign-off around it. Closing paragraphs are where AI drafts pile up phrases like look forward to the opportunity and thank you for your consideration. Paste the closing on its own and the [AI humanizer](/ai-humanizer) will flatten it into something you would say out loud.
Name something only that company does, then say what you did that connects to it. AI fills that paragraph with words like innovation, excellence and mission, which fit any employer and therefore say nothing. Swap them for a specific product, market or problem you can point to. Then run the paragraph through the [AI checker](/ai-checker) to see whether the phrasing still reads as machine-written.
