## 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

## GPTZero

GPTZero grew out of the practical problem that teachers and editors faced once generative text became common: how do you tell whether a piece of writing came from a person or a model? The product answers that with a detector that returns an overall AI likelihood score and highlights individual sentences it considers machine-written, so a reader can see where the suspicion comes from rather than just receiving a single verdict.

Over time the platform widened from a single text box into a suite aimed at institutions. Detector results are paired with a plagiarism checker, grammar and writing feedback, and optional process verification such as a writing replay that records how a document was typed. A Chrome extension and Google Docs add-on push detection into the tools students and staff already use, and the company offers classroom integrations plus an API for bulk or programmatic checks.

Because the buyers are largely schools, districts, and universities, GPTZero leans heavily on privacy and compliance claims: it states SOC 2 Type II compliance and alignment with FERPA, GDPR, and CCPA, and says student writing is not used to train models. The practical takeaway is that it is positioned as an academic-integrity and editorial-review tool rather than a novelty checker, which also means its more powerful features sit in paid tiers.

**Pricing & Plans:** Freemium plus paid plans. A free tier provides core detection with character limits per scan, while paid individual and institutional plans unlock advanced scan modes, higher limits, writing reports, and classroom integrations. Enterprise and API access are quoted separately.

- **Sentence-level AI detection:** Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
- **Multi-model coverage:** Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
- **Browser and docs extensions:** A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
- **Plagiarism checking:** Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
- **Writing process verification:** Writing replay and advanced reports offer evidence about how a document was produced, useful for academic integrity workflows.

**Strengths:** Sentence-level highlighting shows why a passage was flagged instead of only giving a score; Covers text from many different AI model families, not just one chatbot; Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows; Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review

**Limitations:** Detection is probabilistic and can flag polished human writing or miss lightly edited AI text; Free scans are capped by character count, and useful reporting features require payment; Lean heavily on a single score without human judgment can lead to unfair accusations
