## 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

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
