Phrasly AI Detector covers text and image. For text, the detector page names ChatGPT (ChatGPT 4o, ChatGPT 5 and 5.1), GPT-5, Claude (all versions), Google Gemini and Bard, Meta Llama models, Perplexity, DeepSeek, Grok, and Jasper, Copy.ai and other AI writers (detector page, read 8 November 2026). Two sections of the same page list different generators, and the card carries the union of both lists.

Phrasly says the detector works with English, Spanish, French and German text, per the detector page read 8 November 2026. The Business API docs list English as the primary supported language; the card describes the consumer detector, so the count is four, and the API is noted as a separate surface.

On humanized text, Phrasly says the detector distinguishes between text completely generated by AI and human writing that used AI tools for grammar checking or editing assistance. Phrasly also sells its own AI Humanizer, which the detector page describes as a way to transform text into writing that is "less likely to trigger detection" (detector page, read 8 November 2026). Two related cards: ZeroGPT and Walter Writes, both of which also bundle a detector with a humanizer.

Phrasly's privacy policy, last updated 29 June 2023, does not mention submitted text and says information is kept "for as long as necessary to fulfill the purposes outlined in this privacy notice" (Phrasly privacy policy, read 8 November 2026). The detector page says text is "deleted immediately after analysis", and the terms, last updated 12 October 2026, grant Phrasly a perpetual, irrevocable licence to use, copy, store and exploit Contributions. The card leads with the privacy policy and keeps both other statements visible, because the three documents disagree.

The Business API accepts at least 50 words and at most 15,000 characters per request, with bulk scans from a CSV of up to 100 documents (Phrasly AI detection API docs, read 8 November 2026). The two limits belong to two surfaces, and the card labels each.

Prices are from the Phrasly pricing page read 8 November 2026. The detector is included with every Phrasly plan; the paid tiers price the humanizer and generator, and Phrasly shows the Unlimited price with annual billing only. The pricing toggle reads "Annual SAVE 45%", while the homepage FAQ says "save up to 60% compared to paying monthly"; the card uses 45% from the pricing page. The free tier has no stated period because Phrasly caps neither scans nor characters.

What the vendor claims

The AI detector and AI checker are stated at 99.8% for accuracy and 100% free to use. Phrasly's AI checker achieves 99.8% in accuracy when detecting AI-generated text from the latest models including ChatGPT, Claude, Gemini, and other AI writing tools. (FAQ: the figure applies to fully AI-generated content.)
phrasly.ai/ai-detector, read

Phrasly states an accuracy figure of 99.8% for its detector and checker and says they are "100% free to use". The page FAQ adds that the 99.8% figure applies to fully AI-generated content (phrasly.ai/ai-detector, read 8 November 2026). On false positives, Phrasly says: "Although we are constantly improving our algorithms, please note that no method of detection is 100% accurate. False positives are inevitable, but we are working hard to reduce them as much as possible."

The qualifier changes what the headline measures: 99.8% describes fully AI-generated text, not mixed or edited text. Phrasly adds that false positives are more likely for writing in a very formal academic style, predictable phrasing, technical topics with standardized terminology, or a non-native English speaker writing in simple, clear sentences (detector page, read 8 November 2026).

What independent studies found

No study in the index has tested Phrasly; the detectors that have been tested are ranked on AI detectors ranked by independent testing.

The 99.8% on Phrasly's page is the vendor's own figure for fully AI-generated text. Until a published study puts Phrasly on a shared sample, that number has no outside base to stand against.

Where Phrasly appears in the index

Phrasly appears in one ranking: AI detectors by languages supported, at four languages, per the detector page read 8 November 2026.

Phrasly sits on three audience views: AI detectors for business and AI detectors for copywriters and agencies, because of the Business API and its CSV bulk scans of up to 100 documents, and AI detectors for job applications, because the detector is free with no scan cap. The detector hub lists all twenty-two cards.
