AI detectors ranked by named integration surfaces

Field sorted: the number of the eight named integration surfaces each card's integrations field states, compiled on 9 November 2026 from the vendor pages recorded on the cards (read 8 November 2026 for the first sixteen cards and 9 November 2026 for the twenty-two added that day). The eight surfaces: a Chrome or browser extension; a Google Docs add-on or extension; a Microsoft Word add-in; a named learning platform (Canvas, Moodle, Blackboard, D2L or Brightspace, Schoology, Google Classroom, Sakai or Edsby); Zapier; an MCP server; a documented REST API (the card's API field); a mobile app on iOS or Android. Direction: more ranks higher. Tie rule: more study records on the card first, then product name alphabetically, which is why GPTZero (12 records since Pegoraro 2023 was added on 9 November 2026) leads the five cards at 5 and Walter Writes stands alone at 6. Qualification rule: at least one of the eight surfaces named on a vendor page; a card whose integrations field is empty, or names only things outside the eight (bots, SDKs, a self-hosted demo), scores zero and is listed apart. Three entries are excluded on the vendor's own wording and the exclusions are recorded in the index data file: Surfer's Google Docs extension and WordPress plugin serve its Content Editor and "not the detector"; TruthScan's "Word, PDF and Google Docs document processing" is a file-type statement; ZeroGPT's "LMS or enterprise systems via API (no named LMS)" names no platform. 34 of 38 qualified on 9 November 2026; 38 of 72 qualify after the fifth wave, Resemble Detect at 3 of 8 and Illuminarty, Codeleaks and Pindrop Pulse at 1 of 8. Full rules: methodology page; no record in the studies index measures integrations, and the API slice and LMS slice list the cards behind two of the surfaces.

Three pages added 9 November 2026 read the integrations field from other angles: the LMS coverage ranking counts the named LMS platforms that this ranking folds into one surface, the offline question reads the on-premise and self-hosted entries, and the Canvas without Turnitin question reads the Canvas names.

A vendor can name the same surface three ways and the count stays at one: GPTZero lists a Chrome extension "(Gmail, Google Docs, Classroom, social media)", then Google Docs, then Google Classroom as separate lines (gptzero.me, read 8 November 2026), which this ranking reads as three surfaces, extension, Docs and LMS, not five. Sapling lists "73 integrations including Zendesk, Salesforce, Slack, Notion, WordPress" for its writing product (sapling.ai, read 8 November 2026); none of those is one of the eight, so the line adds nothing to the count while the Word add-in, Docs, Chrome, MCP and API lines do. Reality Defender names SDKs in five languages, webhooks, RealMeeting for Teams and RealCall for call centres (realitydefender.com, read 9 November 2026) and scores 1, because only the API is among the eight. The API slice counts 39 cards with an available API and the LMS slice counts 14 cards naming a platform; both read the same fields this ranking reads, so the three pages agree card by card.

Twelve cards name a Google Docs route among the surfaces counted here, an add-on, an extension or a Docs integration; the Google Docs question, added 9 November 2026, lists them and records that no card states a pasted share link as an input.

The mobile app surface counted here is the whole of the mobile apps view: five cards name an iOS or Android app, and the view quotes what each page says the app is, read 10 November 2026.
