Is the cover letter check really free?

Yes. The detector accepts PDF, DOCX, RTF and TXT files up to 50MB, and you can also paste text directly without uploading anything.

Is my cover letter stored?

Not normally. The detector runs analysis in memory and discards the text immediately, and the site states it does not use tracking cookies or sell data. Generation features send resume data to paid third-party AI providers under GDPR terms, so the site recommends stripping personal details first.

How does the AI detection actually work?

It is a fine-tuned BERT model trained on a custom dataset of cover letters rather than a general-purpose text detector. The company cautions that no detector is 100% accurate, and it published a notice in October 2026 that outputs from the newest frontier models now frequently read as human.

What formats and features does it support?

CoverSentry supports multiple formats (PDF, DOCX, RTF, TXT) and pasted text, gives a confidence score with a human / mixed / AI verdict, and adds a free ATS-friendly CV builder with no registration popups and no watermarks.

Can I use ChatGPT to write a cover letter and still get hired?

Yes. Using AI to draft is not disqualifying — the issue is submitting text that reads as templated. CoverSentry suggests adding concrete personal examples, varying sentence length and removing boilerplate phrasing, then rescanning.

Does it work for non-English cover letters?

Currently English only. The detection model was trained on English-language cover letters, and the team says additional languages are under research.

Instant AI-generated score

Upload a PDF, DOCX, RTF or TXT file, or paste text, and receive a percentage score with a human, mixed or AI verdict in seconds.

Cover-letter-specific model

The scanner was trained on a custom corpus of cover letters rather than generic web text, so it recognises the specific templates applicants reuse.

The detector stores nothing — documents are analysed in memory and discarded immediately, and the site does not use tracking cookies.

Actionable humanising tips

Each scan returns concrete rewrite suggestions aimed at the phrasing patterns that make letters read as machine-written.

Free CV builder with 1,200+ job titles

Build an ATS-friendly resume with ready-made bullet points for more than 1,200 job titles, then download as PDF or DOCX with no watermark.

Community scan benchmarks and data

CoverSentry is a free web tool that scans a cover letter and estimates how likely it is to read as AI-generated, then gives recommendations for making it sound human. It pairs a fine-tuned detection model with a no-registration CV builder that produces ATS-friendly resumes.
