## Checkstep

Checkstep is built for the teams responsible for keeping user-generated and professional content safe: trust and safety, content operations and compliance leaders at gaming, marketplace, streaming, dating, social and review platforms. Rather than a single classifier, it provides an integrated platform where policy is defined once and then enforced consistently across every content type and language.

At its core is a configurable policy engine covering the major abuse categories. You set what is and is not allowed on your platform, and Checkstep's workflow and automation layer applies those rules. An AI marketplace gives access to leading moderation models so teams can determine which fits their policy and content needs, test alternatives and swap models without re-engineering the whole pipeline. Moderation itself blends automated scanning from ModBot with human review, letting specialists focus on the highest-risk or most nuanced cases.

Compliance is a first-class feature: the platform centralises the data required under the EU Digital Services Act and can generate transparency reports for European users on demand. Checkstep reports a 90% reduction in human moderation costs, 78% faster moderation and 98% detection accuracy, and works with handpicked BPO and technology partners for customers who need extra capacity. Public case studies include Trustpilot, JustGiving, Star Stable and 123 Multimedia.

**Pricing & Plans:** Free trial available; full pricing is provided on request after a demo, with costs depending on content volume and deployment scope.

- **Multi-format moderation:** Scan and moderate text, images, video and audio in more than 100 languages from one integrated platform.
- **Configurable policy engine:** Define your own rules across all major abuse categories, then let the workflow and automation layer enforce them consistently.
- **AI model marketplace:** Access leading moderation models, test which fit your policy, and swap providers seamlessly without rebuilding pipelines.
- **Human-in-the-loop workflows:** Blend automated ModBot screening with expert review so your team focuses on the cases that matter most.
- **DSA transparency reporting:** Centrally manage regulatory data and generate transparency reports for your European users instantly.

**Strengths:** One platform covers text, image, video and audio in over 100 languages; Policy engine plus model marketplace lets you tailor and swap AI models without rework; DSA transparency reporting is built in, easing regulatory compliance; Documented case studies with named customers and published efficiency figures

**Limitations:** Pricing is not published, so you need a demo and quote before budgeting; Enterprise-oriented setup means it is not aimed at small communities or solo developers; Effective deployment still requires staff to define policy and manage human review queues

## 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
