## 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

## StealthWriter

StealthWriter is built around two steps: scan and rewrite. The detector highlights sentences that still read as AI-written, and the humanizer then rewrites the text to smooth those passages out. Because you can run the detector again afterwards, it works as an iterative loop rather than a one-shot button, which makes it more practical for longer articles where only a few paragraphs sound robotic.

The tool targets people who draft with large language models but publish under their own name: bloggers, marketers, copywriters and researchers. Output can be tuned by rewriting level and, at the sentence level, by picking from alternative phrasings. Processing is quick — typically a matter of seconds — and the free tier with 10 daily humanizations and 1,000 words per input is enough to test whether the tone matches your writing style. Paid plans raise both the daily allowance and the maximum input length, which matters if you humanize long-form content regularly.

StealthWriter is a service of AiVantage LLC. On privacy, the company states that text submitted for humanizing or scanning is not stored after processing, not shared with third parties and not used for training. It is best treated as a drafting and polishing assistant: it improves how naturally AI-assisted text reads, but you should still review facts, claims and citations yourself before publishing.

**Pricing & Plans:** Freemium. The free plan costs $0 and includes 10 humanizations and 10 AI scans per day with up to 1,000 words per input. Paid tiers are Starter at $20/month (50/day), Plus at $50/month (150/day), Pro at $100/month (350/day) and Scale at $400/month (2,000/day), each allowing 5,000 words per input, with discounts for annual billing.

- **AI text humanizer:** Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
- **Built-in AI detector:** Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
- **Alternative rewrites per sentence:** Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
- **Fast batch processing:** Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
- **Volume-friendly quotas:** Daily allowances scale with your plan, from 10 humanizations a day on the free tier up to 2,000 a day on the Scale plan, for high-volume content workflows.

**Strengths:** Free plan lets you test the humanizer and detector at no cost; Detector and humanizer in one workflow makes quality checking easy; Sentence-level alternative rewrites give fine control over tone; Three rewrite strengths suit different content types

**Limitations:** Monthly quotas are metered per day, so bursty heavy users may hit limits; Humanised text still needs a human read-through for factual accuracy; Result quality varies by language and by how obviously AI-written the source is; No built-in grammar or plagiarism checker beyond the AI detector
