## Openlayer

Modern companies run dozens of AI systems across business units — copilots, agents, models, and internal tools — but few can list them all, fewer can test them systematically, and almost none can prove to a regulator what any given system did last week. Openlayer was built to close that gap. It organizes AI control into layers that each deliver value on their own: discovery and org-wide inventory with shadow-AI detection, a registration and risk-tiering registry, pre-release evaluation suites, production observability and tracing, security guardrails, compliance mapping, and cost controls.

On the testing side, Openlayer ships a large library of ready-made evaluations covering quality, security, performance, and safety dimensions, including LLM-as-a-judge scorers and session-level metrics. Teams can write custom tests, wire them into CI/CD so regressions block a release, and inspect traces with per-request cost and latency breakdowns when something goes wrong. In production the same tests run on a schedule or in response to live traffic, with alerting integrations and subpopulation analysis that surfaces whether a problem is concentrated in one user segment.

Governance is where Openlayer differentiates most clearly. Systems are registered with an owner, purpose, data sensitivity, and lifecycle stage, and tracked through intake, development, staging, production, and retirement gates. Compliance frameworks such as the EU AI Act and risk models like NIST AI RMF are mapped so policies become checklists with progress tracking, and Enterprise customers can generate evidence packs and deploy on-premise or in air-gapped environments. The result is a platform that spans engineering, security, and compliance workflows rather than serving only one of them.

**Pricing & Plans:** Openlayer offers a free Basic plan covering one member, five projects, 20,000 monthly requests, three months of data retention, the AI test library, CI/CD integration, observability, alerting, and community support. The Enterprise plan is custom-quoted and adds unlimited members and projects, role-based access control, SAML SSO, explainability, data annotation, custom retention, on-premise deployment, compliance reporting, a 99.99% SLA, and white-glove onboarding.

- **AI test library and custom evals:** Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
- **CI/CD regression testing:** Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
- **Observability, tracing, and cost analytics:** Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
- **Governance registry and lifecycle gates:** Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
- **Compliance mapping and audit evidence:** Built-in frameworks such as the EU AI Act and NIST AI RMF turn policy into tracked rules, so you can see progress per project and export the evidence regulators and auditors ask for.

**Strengths:** Covers the full loop from pre-release testing to production monitoring and governance in one platform; Strong compliance and risk-mapping capability built for regulated industries; Generous free Basic plan makes evaluation tooling accessible to small teams; CI/CD integration lets quality gates block releases automatically

**Limitations:** Enterprise pricing is custom-quoted, so costs are not transparent up front; Compliance reporting and the deepest governance features sit behind the Enterprise plan; The breadth of layers can be a lot to adopt at once for teams that only need basic evals; Small free plan limits (one member, five projects) make it a try-it tier rather than a team plan

## 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
