## Copyleaks

Copyleaks has focused on content integrity since 2015, starting with plagiarism detection and expanding into AI detection and governance as generative models spread. Its core AI Detector analyzes text across more than 30 languages and can identify output from leading models such as ChatGPT, Gemini, Claude and DeepSeek, while its Plagiarism Checker searches a database covering 60 trillion websites, 16,000+ open-access journals and millions of internal documents to catch copying, paraphrasing and character manipulation. A unified multi-modal layer adds detection for video, audio and images, aiming to replace fragmented single-purpose tools.

For organizations, Copyleaks goes beyond individual checks with a scalable API that plugs content analysis into existing workflows, LMS platforms and publishing pipelines. Its compliance and governance use cases map to academic integrity, generative AI governance, code governance, IP and copyright protection, and detection of unauthorized LLM usage. Reporting dashboards, integrations and role-based controls help teams act on results at scale.

Founded as a plagiarism tool, Copyleaks now serves both individuals and large institutions. Free web tools give students and writers quick access to the AI Detector and Plagiarism Checker, while paid enterprise plans provide higher volumes, richer reporting and dedicated support. The company reports 100+ countries, 500+ enterprise and education customers and tens of millions of monthly scans.

- **AI content detection:** Identifies AI-generated text across 30+ languages and leading LLMs, with reported accuracy above 99% on internal English test sets.
- **Plagiarism checking:** Searches 60 trillion websites, 16,000+ open-access journals and internal repositories to catch paraphrasing and hidden copying.
- **Multi-modal detection:** Extends detection to AI-generated video, audio and images so teams can verify content beyond text alone.
- **API and integrations:** A scalable API and workflow integrations automate content analysis inside LMS platforms, publishing tools and enterprise systems.
- **Governance and compliance:** Supports academic integrity, GenAI governance, code governance and IP protection programs with reporting and controls.

**Strengths:** Combines AI detection and plagiarism checking in one platform; Broad language coverage and a very large comparison database; Scalable API and workflow integrations for enterprises; Free tools available for individuals alongside paid plans

**Limitations:** Pricing is quote-based and aimed mainly at organizations; AI-detection results can produce false positives on human writing; Full feature set requires an enterprise contract

## ShieldLabs

ShieldLabs is a fraud detection and prevention platform built for teams that run signups, logins, subscriptions or paid traffic on their own product. Instead of asking you to train a fraud model, it ships ready-made detections: device and browser fingerprints, IP and network intelligence, named risk signals, and High-Risk Events such as multi-accounting, account sharing, impossible travel and account takeover. Each visit gets a Risk Score from 0 to 100 classified as trusted, suspicious or dangerous, with the individual signals listed behind that score.

The core idea is identification before detection. ShieldLabs recognizes a returning visitor even if they clear cookies, browse in incognito or switch IP addresses, and links accounts that use different email addresses but belong to the same person or device. That linking step is what makes account-level abuse detectable without any fraud model training. On top of that sit masking detections for VPNs, proxies, Tor, private relays, datacenters, anti-detect browsers and spoofed locations, plus automation and headless-browser signals, with AI crawler traffic separated from abusive bots.

For analytics-minded teams there is traffic quality scoring: one score for the whole traffic stream plus quality breakdowns by source, channel, referrer and UTM campaign, which helps separate real acquisition results from bot-filled ones. Integration is a JavaScript snippet plus a REST API, webhooks and SDKs across common stacks, and the same free tier exposes the full detection stack with a monthly identification allowance.

**Pricing & Plans:** Freemium with usage-based paid tiers. The free plan includes 5,000 identifications and one domain with the full detection stack. Paid plans are sold as monthly identification volume with hard caps and no overage charges: Starter is $99/month for 25,000 identifications, Growth is $399/month for 150,000 and Scale is $999/month for 500,000. Annual billing saves about 20%.

- **Visitor and device identification:** Recognizes returning visitors across cleared cookies, incognito sessions and changed IP addresses, and links multiple accounts that trace back to the same person or device.
- **Ready-made High-Risk Events:** Flags multi-accounting, account sharing, account takeover and impossible travel out of the box, with a confidence value per event and no fraud model training required.
- **Masking and bot detection:** Names the risk signals behind each result: VPN, proxy, Tor, private relay, datacenter, anti-detect browser, incognito mode, JavaScript disabled, OS and timezone mismatch, browser automation and AI bots.
- **Risk scoring and traffic quality:** Scores every visit 0–100 and classifies it as trusted, suspicious or dangerous, then aggregates a single traffic-quality score with breakdowns by channel, referrer and UTM campaign.
- **API, webhooks and cluster graph:** Ships a single REST API, webhooks, a dashboard explorer and a cluster graph that shows connected accounts and the evidence behind an abuse decision, with SDKs for JavaScript, React, Next.js, Node, Python, Go, PHP, Java and .NET.

**Strengths:** Full detection stack on every plan, including the free tier, so nothing critical is locked behind an enterprise quote; Identification-led approach catches multi-accounting even when emails and IP addresses change; Transparent usage-based pricing with hard caps and no overage surprises; Named risk signals and event confidence make manual review evidence-based rather than guesswork

**Limitations:** Free tier stops returning results once the 5,000 monthly identifications are used, returning HTTP 402 until you upgrade; Identification history is limited to 90 days on every plan; Enterprise-scale volumes above 500,000 identifications per month require contacting sales rather than self-serve
