## 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

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
