Pangram AI Detector

Open a downloaded text, image or plagiarism record on this device, including when private history is unavailable. Nothing is uploaded. An editable JSON file cannot authenticate a past Pangram result.

60–1,500 words and at most 12,000 characters per text check.

Three checks per account per UTC day, subject to a checker-wide daily limit. A started check counts even if Pangram cannot finish; it never uses your humanizer allowance.

Each file uses one of your three checks per account per UTC day. Extract locally, review and confirm every text below, then start the batch. Checks run one at a time. A started check counts even if it cannot finish.

Plagiarism: up to six preparations and three submitted plagiarism checks are allowed per account per UTC day, at two credits per 100 words. A failed preparation uses one preparation slot but no Pangram credits. A submitted attempt counts even if Pangram cannot finish; it never uses your humanizer allowance. A source match is a lead for review, while no match is not proof of originality. This check does not verify a saved EndSchool assignment.

Choose, drop or paste a PNG, JPG or WebP image from 512 × 512 pixels up to 30 MB. BMP, TIFF and HEIC/HEIF are display-only previews; checks accept PNG, JPG and WebP originals. Selecting an image does not start a check. Image detection is separate from text detection and your humanizer allowance.

Choose up to ten original PNG, JPG or WebP files, at most 60 MB combined. Review and confirm each preview, then press Start image batch once. Checks run in order and stop on a limit or uncertain result. The current proxy allows one image check per account per UTC day, so later queued images may remain unscanned. This is an EndSchool proxy queue, not Pangram's native batch tool.

One image check, at most five submitted image uploads, and three public image-URL previews per account per UTC day, subject to separate checker-wide limits. A started check counts even if Pangram cannot finish. The result is an estimate about this image, not a text or plagiarism verdict.

Check summaries are kept for up to 30 days and load 50 at a time. Use Load older checks to see more; filters apply to the checks loaded so far. Your submitted text and image bytes are not saved in this history, except that a check keeps its first words, or an image's file name, as its name for as long as the check is kept, and a text, image or plagiarism check keeps Pangram's screenshot of its result, which shows what was checked, for up to 2 days. Download a complete record at the time of a check if you need its original content. When sharing is enabled, you can explicitly create a 24-hour public summary link; it does not include source text, section text, notes, tags, or the input digest.

A text URL preview fetches a public HTTPS article and extracts its visible text for your review. An image URL preview retrieves one public HTTPS PNG, JPG, WebP or BMP for you to inspect; BMP checking remains unavailable. Neither preview runs Pangram or stores a document here. This displays Pangram's result for the exact text or image bytes submitted in the separate check. Detector classifications are estimates and can differ between tools. This manual diagnostic does not verify a saved EndSchool assignment or a humanizer result. It does not claim that another detector checked your text. Text or image bytes are sent to Pangram only when you explicitly press a check button. Downloaded and natively shared text or plagiarism records include the exact text; image records include only its file hash. Downloads stay on your device unless you choose to share them.
