You upload or generate a rubric, drop in student work — typed essays, scanned handwritten math, worksheet answers, lab reports or exam pages — and the platform returns rubric-based scores with the reasoning behind them plus student-facing feedback you can edit. Because the evidence sits next to each score, reviewing a class set becomes a check-and-adjust task instead of a blank-page writing session. Beyond single assignments, GradingPal tracks mastery against standards frameworks including Common Core, NGSS, AP, IB and GCSE/A-levels as well as US state standards. Classroom analytics surface shared strengths, recurring misconceptions and progress against learning objectives, then suggest what to reteach or which students may need support. Integrations with Google Classroom, Canvas and Schoology let feedback flow back into the tools teachers already use. GradingPal offers a free tier covering 50 submissions a month with handwritten work support, rubric upload or AI-generated rubrics, six feedback styles and Google Classroom integration. Paid teacher plans raise or remove the submission cap and unlock analytics, extra assignment types and priority support, while schools and districts get pooled access, a custom standards library, a data privacy agreement and onboarding. **Pricing & Plans:** Freemium, Free Trial, Contact for Pricing, Free [Profile (Markdown)](https://openaitools.app/tool/gradingpal.md) ## ZeroGPT ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. 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 GradingPal and ZeroGPT compare in monthly traffic?
