It pairs a fine-tuned detection model with a no-registration CV builder that produces ATS-friendly resumes. ## 價格與方案 Free to use for cover-letter scans and the ATS-friendly CV builder, with no signup or cookies required for the detector. Optional account features and generation tools are available for logged-in users. ## 關鍵功能與能力 - **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. - **In-memory privacy-first analysis:** 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:** Aggregate pages show recent scan outcomes and the share of scanned letters that sounded convincingly human, so you can benchmark your own result. ## 主要使用情境 - **Checking an AI-assisted application before sending (Job seeker):** Run a draft letter through the scanner, fix the flagged phrasing and rescan until the score reflects your own voice rather than a chatbot's. - **Triaging high-volume applications (Recruiter or hiring manager):** When hiring, use the detector as a light signal alongside reading the letter, knowing that the newest frontier models can defeat it entirely. - **Building an ATS-safe resume (Career changer):** Generate an ATS-friendly resume with pre-written bullet points for your job title, then pair it with a humanised cover letter. - **Coaching candidates on application quality (Career coach or university advisor):** Advise candidates on how much AI drafting is realistic in a specific market, and show them concrete before-and-after scores. ## 優勢 - Completely free cover-letter scanning with no signup wall in front of the detector - Privacy-first design: documents are analysed in memory and discarded, no tracking cookies - Model is fine-tuned specifically on cover letters rather than generic text detection - Returns an actionable score with rewrite suggestions instead of a bare verdict - Companion CV builder covers 1,200+ job titles with PDF and DOCX export and no watermark - Publicly discloses when detection accuracy degrades instead of overstating confidence ## 限制 - The site itself notes frontier models increasingly pass as human, so detection confidence has limits - Cover-letter checking is English-only - It is a screening-preparation tool, not a guarantee you will pass a recruiter or ATS - Accuracy is strongest on the specific cover-letter data it was fine-tuned on, not general long-form text ## 常見問題 ### 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. ### CoverSentry 的每月流量與成長趨勢為何？ CoverSentry 目前每月有 6906 次造訪，月流量變化為 -922（成長率 -11.8%）。其主要來源市場為美國（佔比 58%），其中包含每月 2753 次直接造訪與每月 — 次自然搜尋造訪。 ### CoverSentry 是免費的嗎？其定價模式為何？ CoverSentry 採用免費增值定價模式。Free to use for cover-letter scans and the ATS-friendly CV builder, with no signup or cookies required for the detector.
