Not a FormSubmit submission - an inbound affiliate/partnership offer to partnerships@aidetector.cx, held from 2026-10-06 pending two publication blockers. Editorial entry written independently; no vendor copy reused. Both blockers verified cleared on the live site 2026-10-08: (1) the training-use contradiction is gone - both /detector and /privacy now state submitted analysis text is not used to train or fine-tune detection models on any plan, and the old Enterprise/Professional-scoped opt-out sentence no longer exists; (2) the four named third-party testimonials (Forbes / Stripe / HubSpot / Nature Portfolio) have been removed from /detector. The vendor also removed the SOC-2 Type II footer claim and the 98.7% / 1.2s / 12.4M+ / 142+ marketing figures. Verified the same day from the live pages: /pricing (plans 12/29/79 monthly, 120/290/790 annual, 300/1,000/3,000 credits), /privacy (data controller AIDetector.cx Inc., Berkeley CA; 12-month analysis history retention, deletable from the dashboard; no training use), /terms (you retain ownership of submitted content; output licensed for personal or commercial use; governed by California law), /cookies (Cloudflare / Stripe / Supabase), and a sitemap listing ~40 pages. Operator: AIDetector.cx Inc., a named legal entity, not a sole-proprietor microsite. Name is shared with unrelated live detectors on aidetector.com and aidetector.ai, so the listing carries the exact .cx domain. Affiliate terms confirmed in writing 2026-10-08 - 30% recurring on eligible subscription payments for the lifetime of the customer, monthly and annual eligible, 30-day attribution window, 30-day hold, $50 minimum payout.

Pay-as-you-go one-time credit packs, USD, no subscription: 1,000 credits $19, 5,000 $79 (most popular), 10,000 $149, 20,000 $249; a once-per-account first purchase of the same four packs at $9.90 / $49 / $98 / $196; 100 free credits at signup; credits never expire and work in the app and the API. Consumption: 100 credits per 1,000 words rewritten by the humanizer, 5 credits per 1,000 words for citation-format correction. Verified on three surfaces that agree - the rendered /pricing page (four cards, first-purchase prices shown beside list prices), the site's own public endpoint /api/backend/v1/credits/packages?locale=en (eight items: four 'first_*' packs at the discounted cents values and four standard packs at 1900/7900/14900/24900 cents, currency USD, every provider 'waffo', default_provider 'waffo', first_purchase_available true, no recurring flag on any item), and the pricing page metadata ('1,000 credits for $19, or $9.90 on your first purchase'). The Terms state each purchase is a one-time charge and the only mention of a recurring plan is a future conditional ('Credits granted by a future membership plan would expire at the end of each period') in the pricing FAQ, so no subscription price exists to verify and none was recorded.

submitted via form by vendor; editorial entry written independently. Received through FormSubmit twice on 2026-10-23 21:35 UTC with a byte-identical payload (INBOX msgs 201 and 202 / All Mail 496 and 497) - one submission, not two; the timestamps carry minute resolution only. Submitted contact nitubag316@gmail.com differs from the support@humanpen.net the site publishes; 'HumanPen' had zero hits in the repo, the hold ledger or any mail folder and no prior outbound mail existed to either address. The site is a Next.js SPA, so much of it is client-rendered: /privacy, /terms, /contact, /affiliates and a dozen other guesses return the identical 56,457-byte app shell and are not the legal pages - the real ones are /legal/privacy and /legal/terms (both in the sitemap, both 200 when rendered) and both are dated 'Last updated: 7 September 2026'. Pricing was read from the rendered page AND from the site's own public packages endpoint; the pack cards do not exist in the served HTML at all, so a markup-only price sweep finds just the $19/$9.90 figures in the meta description and would have under-reported the ladder. Privacy policy contents verified by rendering: processors named as Creem and Waffo Pancake (merchant of record, card data never stored), an unnamed authentication provider, an unnamed cloud object-storage provider and unnamed third-party AI model providers; retention 7 days for uploaded documents and results, 30 days for account deletion, 7 years for payment records; no sale of personal data and no training use. Terms verified: user retains rights to input and output, 16+ eligibility, refunds of untouched purchases within 14 days, credits auto-returned on a failed job, acceptable-use clause that explicitly bars academic dishonesty, indemnification, liability capped at three months of payments, and a governing-law clause that names no jurisdiction ('the laws of the jurisdiction in which the HumanPen team operates'). Tracker finding verified from the served HTML and the live network, not from policy text: the root layout injects googletagmanager.com/gtag/js?id=AW-18511954133 and a Microsoft Ads UET loader for bat.bing.net/bat.js, both with next/script strategy 'lazyOnload'; loading /legal/privacy produced requests to googletagmanager.com, googleadservices pagead/viewthroughconversion/18511954133, google.com/rmkt/collect/18511954133 and bat.bing.com/action, and the page contains no cookie/consent UI element and no consent-mode call. Privacy section 10 says the only cookies are those 'necessary to sign you in and keep the Service working' and 'We do not use them to build advertising profiles', and section 5 names no Google or Microsoft processor. Operator identity: none. 'HumanPen' / 'the HumanPen team' is the only party named on any page; no company, individual, country, postal address or company number appears, and the About page explicitly declines to give a biography. Contact route verified before any reliance on it: SMTP RCPT TO against the domain's own Cloudflare MX (route1/route2.mx.cloudflare.net) returned 250 2.1.0 Ok for support@humanpen.net and 550 5.1.1 Address does not exist for a random local part, so the mailbox is live and the domain is not a catch-all. Domain: RDAP registration 2026-07-17T06:52:45Z, registrar Namecheap, NS elaine/rajeev.ns.cloudflare.com, Cloudflare Email Routing MX. No affiliate or partner page is public - /affiliates and /partners both render the sign-in screen - so no tracking URL exists and none was invented. Name checked: no famous research project, open-source repo or incumbent AI product trades as HumanPen; the product's own footprint is a GitHub org (humanpen) with ai-humanizer-comparison, humanpen-skill and humanpen-mcp, an aicatalog.app directory review, a Hugging Face space and a twelve.tools badge. Documented API defect recorded: GET /v1/health and GET /v1/ready are in the vendor's OpenAPI 3.1 schema and both return 404 on the live API. Category reclassified from the submitted 'Writing & Productivity' to Productivity, which is where this catalog keeps writing/document tools.
