Official sources checked 2026-10-08Open verification questions
- Payment processor attribution differs across two live legal pages - the Privacy Policy names Paystack for billing while the Cookie Policy names Stripe (plus a Stripe cookie table). Both may be accurate for different layers, but the checkout flow was not exercised.
- No independent third-party accuracy evaluation is published; the benchmark figures are the vendor's own results on a 400-document internal corpus.
- Security posture is now unanswered rather than contradicted - the former 'SOC-2 Type II Certified' footer claim was removed in the 2026-10-08 fix, and no replacement certification or audit detail is published.
- The free tier is five one-time introductory checks (1 guest + 4 signed-in), not a recurring free plan.
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.
Individual plans re-confirmed on 2026-10-01 from gamma.app/pricing: free: $0; 400 one-time signup credits that do not refill; up to 10 slides per prompt; PDF, PPTX, PNG, and Google Slides export. plus: $9/seat/month equivalent, $108/seat billed annually; 1,000 monthly credits, up to 100 slides per prompt, branding removal, and advanced image models. pro: $18/seat/month equivalent, $216/seat billed annually; 4,000 monthly credits, premium image models, custom branding, analytics, 10 custom domains, API access, and workspace templates. ultra: $90/seat/month equivalent, $1,080/seat billed annually; 20,000 monthly credits, advanced text/image/video models, 100 custom domains, and early feature access. The page advertises saving up to 28% on annual billing. Team and Business pricing did not render on the 2026-10-01 fetch, so the previously recorded $20/$240 Team and $40/$480 Business figures were not re-confirmed.

- The Team and Business plan prices recorded on 2026-08-25 did not render on the 2026-10-01 fetch and were not re-confirmed.
- The official page was captured in its annual-billing state. Monthly individual-plan checkout prices were not independently captured and should not be inferred from the annual discount.
- Gamma's terms grant a broad training license where training controls are unavailable or left enabled; publications should distinguish individual plans from Team/Business plans.
The repository's 400-credit Free allowance remains supported, but those are one-time starter credits rather than a monthly refill. The repository's Plus $10 and Pro $20 figures do not match the current official annual-pricing view, which shows $9 and $18 monthly equivalents. Paid credits roll over only up to twice the monthly allocation; additional credits can be purchased. Individual Free, Plus, Pro, and Ultra workspaces allow Gamma to use content for AI-feature improvement by default, but users can opt out in account settings. Team and Business workspace content is automatically excluded from training, with the control locked. Gamma does not claim ownership of user content. Users grant Gamma a license needed to operate and provide the service. The pricing page also states that content remains the user's after cancellation or downgrade. Public API documentation is available at https://developers.gamma.app/; the pricing page says API access is available on paid plans and consumes AI credits. Approved and wired 2026-09-13: PartnerStack tracking URL on the Visit CTA. Official pricing, docs, privacy, and terms links stay on gamma.app. Editorial score, cons, and methodology are unchanged. Re-verified 2026-10-01: Free, Plus, Pro and Ultra individual prices and credit allocations are unchanged from the 2026-08-25 record. The Team and Business columns did not render, so those figures remain as recorded earlier rather than re-verified. The FAQ still states that paid credits roll over up to 2x the monthly amount and that Free credits are a one-time allocation.
