Passed.ai

The unit was a credit: "1 credit scans 100 words", 200 credits a month on the subscription, "Additional credits availabe for $0.01 per credit" and "Credits roll over into the next month", with "File upload" listed and the FAQ inviting users to "simply copy/paste your text or drag and drop your files into our app" (archived pricing page, 17 April 2026, read 10 November 2026). No file format and no per-check limit were named, so those fields stay empty. There was no free tier: the subscription carried a "5-day free trial, includes 2500 words", while the archived home page showed both "Start 5-day Free Trial" and "Start a 14-day Free Trial" on the same screen, a contradiction the card records (archived home page, 7 June 2026).

The plans below are the archived pricing page's figures, printed with a dollar sign and no currency name by an Ontario vendor, read 10 November 2026. None is sold at the read date.

The closing notice fixes the end: "Every subscription ends at the close of its current billing period. You won't be charged again, and access ends when the term does" (passed.ai, read 10 November 2026). The notice then lists what Originality.ai offers in its place, including a Chrome extension for "Google Docs and Google Classroom", a feature of the partner and not of Passed.ai, so it adds nothing to this card's fields.

On retention, the privacy policy with a last amendment date of January 29, 2023 separates two kinds of data. For clients: "We retain personal information indefinitely so that Clients can purchase and use our services on an ongoing basis." For the student content clients submit: "We do not retain third-party personal information indefinitely. Instead, we dispose of it (in a way that prevents a privacy breach) within a commercially reasonable period of time, typically 90 to 120 days after it has been processed. We anonymize any Content we retain for legitimate business purposes" (privacy policy, read 10 November 2026). The card quotes both sentences and ranks no period, because "typically 90 to 120 days" is a range with a hedge rather than a stated retention period. The same policy names "our Passed.ai App, Chrome Extension, API" as its surfaces; no API page or documentation existed on the archived site, so the card records the API as not available. Ownership comes from the terms, last amended January 25, 2023: the site "is owned and operated by Fractal SAAS Inc. ... located in Collingwood, Ontario, Canada", governed by the laws of Ontario (archived terms, captured 7 June 2026, read 10 November 2026).

The accuracy claim is the partner's. The AI detection page answered "How accurate is Passed.AI?" with "Passed.AI uses Originality.AI's AI detector, which is 99% (accurate) on GPT-4" (archived AI detection page, captured 17 April 2026, read 10 November 2026). The card writes the figure as 99% (accurate) on GPT-4, quoted and attributed, and the claim gap field pairs it with no study figure because no record tested Passed.ai. The same page described the output: "The AI detection score ranges from 0 to 100 and indicates the confidence level that the assessed content is AI-generated."

The vendor's caveat was its product pitch. The FAQ defined false positives as "instances when the tool wrongly identifies a piece of text as AI-generated when it's actually human-written" and false negatives as the reverse, and answered each with "This is why Passed.AI has implemented secondary checks: they are a safety net" (archived home page, 7 June 2026, read 10 November 2026). On how to avoid both: "Being able to see things like how long it took to create the document, contributions, number of changes etc. are designed to support your decision-making process. Unlike other tools that give a binary answer, Passed.AI gives you a complete picture." No false positive rate was published, and no statement about paraphrased or humanized text was made.
