## Assessment Systems (assess.com)

Assessment Systems is a US-based assessment technology and consulting company whose platform is built for organizations running high-stakes, high-volume exams: certification boards, government HR and licensure bodies, pre-employment programs, universities, and K-12 assessment programs. The core product, FastTest, covers the full assessment lifecycle, from authoring and reviewing items in large banks to assembling test forms, publishing them securely, and analyzing results.

The platform goes well beyond basic multiple-choice quiz software. It supports modern psychometrics such as item response theory (IRT), computerized adaptive testing (CAT), multistage testing (MST) and LOFT, online essay marking, and AI-assisted tools for item development and content detection. Delivery-side features include live and recorded remote proctoring, a test center network, lockdown and watermarking security controls, and a white-label, embeddable engine so organizations can keep their own branding.

On top of the software, Assessment Systems sells consulting: job task analysis, item writing, Angoff standard-setting studies, psychometric analysis, test security audits, and full certification program management. Companion products like Iteman (CTT analysis), Xcalibre (IRT software), and TestAssembler support classical and modern analysis workflows, while the Credicycle candidate portal handles applications, payments, badge issuance, and renewals. Pricing is quoted per engagement.

**Pricing & Plans:** Custom quote only — Assessment Systems does not publish list prices. Prospects are asked to talk to an expert or request a demo; costs depend on exam volume, modules, and consulting scope.

- **Item banking and authoring:** Manage large item pools with metadata, versioning, SME workflow and dozens of item types, plus AI-assisted authoring tools.
- **Secure test delivery:** Deliver high-stakes exams with lockdown browsers, watermarks, AI detection, MFA and configurable scheduling across locations and institutions.
- **Adaptive and personalized exams:** Support IRT-based CAT, multistage testing (MST) and LOFT models for shorter, more precise exams.
- **Proctoring and test centers:** Choose live or recorded remote proctoring, bring your own proctor, or use Assessment Systems' global test center network.
- **Psychometric consulting:** In-house experts deliver job analysis, item writing, Angoff cutscore studies, IRT analysis and NCCA/ISO-aligned validation.

**Strengths:** Covers the whole assessment lifecycle in one platform, from item banking through reporting; Genuine in-house psychometric expertise with IRT, CAT and standard-setting services; Strong security and proctoring options, including remote proctoring and a test center network; White-label and embeddable engine plus APIs for integrations like ATS

**Limitations:** No public pricing; buyers must go through a sales conversation; Enterprise-focused tooling is heavier to learn than simple quiz builders; Consulting services and custom modules can make total cost hard to predict upfront

## 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
