## 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

## Undetectable AI

Undetectable AI focuses on a single practical problem: content that sounds machine-made can be penalized, flagged or distrusted. The platform's detector highlights which sentences a scanner would most likely mark as AI-generated, showing percentages before the humanizer even runs. Once flagged, the humanizer rewrites those segments with varied sentence structure, richer vocabulary and adjusted tone, aiming to keep the original meaning intact while producing writing that reads naturally.

Beyond the core text tools, the product range has expanded into media forensics. There are detectors for AI-generated images, voice, video and deepfakes, plus specialty utilities such as a fake PDF detector, a receipt checker and other document-verification tools. A Chrome extension brings detection and rewriting into Gmail, Google Docs and any other page you are typing on, and an API is offered for teams that want the humanizer embedded in their own workflows.

The platform reports more than 24 million users and supports 50+ languages, though English yields the most accurate results. Business Solutions add stricter data-retention controls, white-labeling and non-expiring credit packs for higher-volume clients. A free tier is available with limited words, and the vendor advertises a money-back guarantee when humanized output is still flagged.

**Pricing & Plans:** Freemium. A free trial covers a limited number of words (currently 250). Paid monthly plans start around $9.99 for 10K words and scale to roughly $42.50 for 50K words, while annual billing discounts those rates by about half (roughly $5.00-$21.25 per month). Custom business tiers add non-expiring credits, redistribution rights and priority support.

- **AI Detector:** Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
- **AI Humanizer:** Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
- **Media authenticity checks:** Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
- **Chrome extension:** Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
- **API and business options:** An API lets teams plug humanizing into existing pipelines, while business plans offer white-labeling, higher volumes and non-expiring credits.

**Strengths:** Detector and humanizer live in one workflow, so you can flag and fix text without switching apps; Wide language coverage (50+ languages) with strong English accuracy; Extra media tools (image, audio, video, deepfake, fake PDF) beyond plain text; Chrome extension makes it usable inside the tools people already write in

**Limitations:** Detector results are probabilistic and can disagree with other detectors or with human reviewers; Free tier caps out at roughly 250 words, so any real workload needs a subscription; Word limits still apply even on paid tiers, so heavy publishing volumes require enterprise pricing; Humanized output sometimes needs a light manual edit to preserve nuance and technical accuracy
