AIDetectPlus is an AI detection remover tool. AIDetectPlus combines an AI content detector, humanizer, plagiarism checker and PDF chat in one web app. It sells non-expiring word-based credits instead of subscriptions, with a free tier and an Enterprise plan for schools and teams.
AIDetectPlus is a web-based toolkit for people who need to know how a piece of writing will read to an AI detector, and who want to change the result when it reads badly. Its core tools are an AI detector, an AI humanizer and a plagiarism checker, supported by an LLM chat and a chat-with-PDF feature. The site targets students, teachers, professors and marketers, and says it handles essays, blog posts, papers and social media text from any major AI model. The detector returns paragraph-level analysis and explains why a passage would trip detection systems, which is more useful than a single overall score when deciding what to rewrite. The humanizer rewrites AI-generated text in a tone the user selects, aiming to get it past popular detectors. The plagiarism checker looks for exact matches and similar content across the web, so a writer can confirm originality and add proper citations. The chat tools give access to current language models and let users upload PDFs or notes to ask questions and pull out key points. The service says it works in several languages, and tasks can be deleted after a report is generated. Billing is the main point of difference. Instead of a monthly plan, users buy credit packs where one credit equals one word, and the credits do not expire. A free tier covers detection, plagiarism checks and chat, while humanization and API access sit in the paid credit tier. An Enterprise option adds bulk processing, exportable reports, volume discounts and a dedicated account manager, and heavy users are told a subscription exists. Among alternatives, it competes with standalone detectors and humanizers that charge recurring fees. Reviewers quoted on the homepage compare it with GPTZero, Copyleaks, Sapling and StealthGPT, and one notes it is slower than StealthGPT while costing less. Those are user opinions rather than independent benchmarks, so accuracy claims should be tested on the buyer's own documents.
