Its core idea is that making student thinking visible lets institutions add value beyond simply catching plagiarism. The platform spans inquiry-based Discussions, a Writing feedback tool, AI-Integrated Assignments, a practice-focused Writing Lab, and an Originality solution for academic integrity. Packback positions itself as pedagogy-first and research-backed. Rather than delivering a generic chatbot, it layers AI coaching directly onto assignments: in Discussions, students are nudged toward better questions and sourced answers; in Writing, they receive formative feedback while drafting and instructors get assistance evaluating structure, grammar, and formatting. Its newest assignment type, "Teach the AI," asks students to explain a concept and defend their reasoning to an AI learner, producing a concept map and rubric report for the instructor. Packback is sold to institutions rather than individuals. It reports adoption across more than 600 higher-ed and K-12 institutions and cites measurable outcomes — roughly double the posts citing sources versus an LMS, about 30% less instructor grading time, and higher student writing confidence. The platform emphasizes compliance and access, listing SOC 2 Type 2, FERPA and COPPA student-data protections, WCAG AA accessibility, and LTI Advantage certification for LMS integration. **Pricing & Plans:** Contact for pricing. Packback is sold to institutions rather than individuals, so there is no public price list.

The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation. Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%. Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app. **Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations. - **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report. - **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals. - **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning. - **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer. - **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale. **Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper **Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language [Profile (Markdown)](https://openaitools.app/tool/zerogpt.md) ## Frequently Asked Questions ### How do Packback and ZeroGPT compare in monthly traffic?
