AI detectors with a mobile app: the five cards whose integrations name an iOS or Android app, and what each page says the app is
A mobile app for iOS or Android is named among the integrations of 5 of the 72 cards in the index, by the integrations field and the "Mobile app" surface in the integration count read 8 to 10 November 2026: QuillBot (Android and iOS keyboards and apps), Grammarly (iPhone, iPad and Android), Walter Writes (iOS and Android), Monica (Android and iOS) and Deepware (an Android app whose Google Play listing returned 404 on 9 November 2026 and again on 10 November 2026) (quillbot.com/premium, grammarly.com/ai-detector, walterwrites.ai/chrome-extension, monica.im, deepware.ai). One card cites a store listing by its package name, Deepware's com.zemana.deepware, and that is the one store page the index read live; the other four name the platforms on their own pages and link no store page the card records, so no store page was fetched for them. What the app is matters more than that it exists: four of the five are the vendor's general writing or assistant app, inside which the detector is one tool, and only Deepware's app is the detector itself. This page is one of the views under AI detectors by feature; the platform integrations ranking counts every surface, the no-account view lists what runs with no sign-up, and the full index shows all 72 cards.

One field, read two ways. The integrations field must name a mobile app, an iOS or Android app, or a phone or tablet platform, and the integration count's surfaces list, written from that field, must carry "Mobile app" as a surface; both are true for the same five cards. The table then quotes what the card's page says the app is, because the vendor pages read for the index describe the app as a product and do not say on their own whether the AI detector runs inside it: QuillBot's keyboard and app, Grammarly's mobile app and Monica's assistant app are described as the writing or assistant product, and the index does not infer that the detector tab is present on the phone. The store listing column holds a URL only where the card cites one. Two cards that run on a device but not on a phone are outside the table: McAfee Deepfake Detector runs on the NPU of a Windows AI PC and Hiya's detector is a Chrome extension, as the offline question and the voice and video question record. Field rules are in the methodology.
Which fields decide whether a detector has a mobile app?
| Detector | Platforms as stated | What the page says the app is | Store listing cited on the card | Study records | Source, read date |
|---|---|---|---|---|---|
 QuillBot | Android and iOS, "keyboard and app" | The QuillBot keyboard and app, listed with the Chrome and Edge extensions, the macOS app and the Word add-in | None cited | 2 | quillbot.com/premium, 8 November 2026 |
 Grammarly | "Mobile (iPhone, iPad, Android)" | The Grammarly app, listed with the browser extension, Grammarly for MS Office, Google Docs and the desktop apps | None cited | 0 | grammarly.com/ai-detector, 8 November 2026 |
 Walter Writes | "Mobile app (iOS and Android)" | The Walter Writes app, listed with the Chrome extension, the MCP servers, Zapier and LMS access by API | None cited | 0 | walterwrites.ai/chrome-extension, 9 November 2026 |
 Monica | "Mobile apps for Android and iOS" | The Monica assistant, in which the detector is one tool beside the browser extension and desktop apps | None cited | 0 | monica.im/tools/ai-content-detector, 10 November 2026 |
 Deepware | Android | The Deepware Scanner app itself, free, linked from deepware.ai | Google Play, package com.zemana.deepware; the listing returned 404 on 9 November 2026 and on 10 November 2026 | 0 | deepware.ai, 9 and 10 November 2026 |
Statements as each vendor makes them, read 8 to 10 November 2026 and ordered by study records then name; "None cited" means the card records no store URL, not that no listing exists. The other 67 cards name no mobile app on the pages read.
Why each card is in this view
- AIDI-D-0007QuillBot
the premium page lists Android and iOS keyboards and apps beside the extensions and the macOS app, the longest surface list of the five (quillbot.com/premium, read 8 November 2026); 2 study records, both on the web detector.
- AIDI-D-0008Grammarly
the detector page lists mobile among its surfaces as "Mobile (iPhone, iPad, Android)", naming the tablet as well as the phone (grammarly.com/ai-detector, read 8 November 2026); no study record.
- AIDI-D-0015Walter Writes
the integrations page names a mobile app on iOS and Android with the Chrome extension and the API surfaces (walterwrites.ai/chrome-extension, read 9 November 2026); no study record.
- AIDI-D-0054Monica
the detector is one tool inside an assistant sold as a browser extension, desktop apps and mobile apps for Android and iOS, and the page states that the tool combines three third-party detectors (monica.im/tools/ai-content-detector, read 10 November 2026); no study record.
- AIDI-D-0037Deepware
the one card whose app is the detector, a free Android scanner linked from the home page, and the one card with a store listing cited; the listing returned 404 on 9 November 2026 and again when read live on 10 November 2026, and the web scanner host was unreachable on 9 November 2026 with no withdrawal statement from the vendor (deepware.ai, read 9 November 2026; play.google.com, com.zemana.deepware, read 10 November 2026); no study record.
What the evidence says about detection on a phone
No record in the studies index ran a detector through a mobile app; every text record pasted or uploaded through a web tool or an API, and the image, audio and video records used benchmarks. The two records on QuillBot's detector, the only app-carrying card with a record, were run on the web product: Kar 2024 read one 500-word ChatGPT article through ten free web tools, and Alshammari and Rao 2025 scored 49 DeepSeek-V3 answers through six web tools (Kar 2024 record; Alshammari and Rao 2025 record), so nothing in the index says whether the phone app returns the same score as the browser. The same-result question covers what the index knows about repeat scoring on one surface.
The one thing a mobile surface changes that the index can read is the data path. Deepware's privacy policy and Monica's, QuillBot's and Grammarly's are read on the cards for the web product, and the data retention ranking records the stated period where one exists; none of the five vendor pages states a separate retention term for the app. A reader who needs a detector on a phone and cares what happens to the text can start from the no-account view, where a web tool that runs in a phone browser with no sign-up is listed, and from the platform integrations ranking, which counts the mobile app as one of up to eight surfaces per card. No detector score should be the only evidence in a misconduct, hiring or publishing decision, and a score read on a phone is the same score with the same error rates.

FAQ: AI detectors with a mobile app
Which AI detectors have an iOS app?
Four of 72 name iOS on 10 November 2026: QuillBot (iOS keyboard and app), Grammarly (iPhone and iPad), Walter Writes (iOS and Android) and Monica (Android and iOS), by the integrations fields read 8 to 10 November 2026; Deepware names Android only.
Which AI detectors have an Android app?
All five cards in the view: QuillBot, Grammarly, Walter Writes, Monica and Deepware, by the integrations fields read 8 to 10 November 2026; Deepware's is the only app that is the detector itself rather than the vendor's wider writing or assistant app.
Is the Deepware Android app still available?
Its Google Play listing, package com.zemana.deepware, returned 404 on 9 November 2026 and again on 10 November 2026, and the web scanner host was unreachable on 9 November 2026; the vendor has published no withdrawal notice, so the card records a live product with an unreachable host, as the shut-down question tracks.
Does the AI detector run inside the mobile app?
The pages read do not say for QuillBot, Grammarly, Walter Writes or Monica: each names the app as the vendor's writing or assistant product and the index does not infer that the detector tab is present on the phone. Deepware's app is the scanner.
Has any study tested an AI detector on a phone?
No record in the studies index has, as of 10 November 2026; QuillBot's two records, Kar 2024 and Alshammari and Rao 2025, were run on the web tool.
