## Roundtable (Proof of Human)

Roundtable began as an AI-powered fraud prevention platform and now operates under the name Proof of Human (Proof of Human, PBC). The roundtable.ai domain redirects to poh.org, and the site explicitly describes the company as formerly Roundtable AI, so the underlying product and team remain active — simply under a new brand and mission framing as a public benefit corporation.

The core of the product is an invisible verification API. Instead of asking users to solve puzzles, it watches how they interact with a page: how they type, where the mouse travels, how they scroll, whether they paste text or leave typos uncorrected, and how their clicks land. Those signals roll into a live behavioral profile that distinguishes real humans from scripts, bots and increasingly capable AI agents. Verification is continuous rather than a one-time gate.

Because the approach is behavioral rather than identity-based, the company emphasizes privacy: no PII is collected and no cross-site tracking is performed. Integration is a single script with a site key and user ID, and the platform reports millions of sessions processed each month with sub-200ms latency backed by SLA guarantees.

Use cases cluster around market research (verifying panel respondents), financial services (account creation and high-risk transactions), ticketing and live events (stopping scalper bots), and general fraud, bot and account takeover prevention. Pricing is quote-based and available by contacting sales or booking a demo.

**Pricing & Plans:** Roundtable (Proof of Human) does not publish public price tiers; pricing is quote-based and available on request. Prospective customers are directed to book a demo or email the sales team to discuss enterprise pricing and volume.

- **Invisible, Frictionless Verification:** Proof of Human runs silently behind login and checkout flows, scoring behavior in under 200 milliseconds without CAPTCHAs or friction for real people.
- **Continuous Behavioral AI:** Continuous behavioral models look for programmatic typing, teleporting mouse movement, jump scrolling, centered clicks and pasted text to catch bots and AI agents mid-session.
- **Privacy-Preserving by Design:** The service states it collects no PII and does no cross-site tracking, helping teams meet compliance and privacy requirements.
- **Effortless Integration:** A single script tag with a site key and user ID is enough to begin verifying sessions, and results include an example session report with explainable signals.
- **Enterprise-Scale Performance:** The platform reports millions of sessions processed monthly and near-instant API latency with SLA guarantees, suited to high-traffic consumer flows.

**Strengths:** No CAPTCHAs, popups or friction for genuine users; Continuous behavioral scoring rather than a one-time human check; Detects modern AI agents as well as classic bots; Privacy-preserving: no PII and no cross-site tracking

**Limitations:** Pricing is quote-based, so buyers cannot self-serve or compare costs upfront; Enterprise buyers must go through a demo and sales process; Continuous behavioral verification can raise privacy review questions before deployment; Previewed prices and plans are not published on the site

## 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
