DisclosureProof is a live-browser evidence tool: it can open the chat, check desktop and mobile, sample media markings and, on paid plans, crawl more pages and watch for changes. Article50.io loads one public page at first view, without opening the chat, and checks voice and avatar widgets and disclosure presentation, free or as a €499 report. Choose DisclosureProof for sealed evidence and monitoring; choose Article50.io for a one-off fix report.

At a glance
Both tools load the page in a real browser; they differ on opening the chat, how many pages they cover, monitoring, and what the paid record contains.
| DisclosureProof | Article50.io | |
|---|---|---|
| How it checks | Real browser, as a first-time visitor; can open the chat widget; desktop and mobile | Real browser, first view only; does not open the chat or click through a consent banner |
| Free scan | Homepage, no account or card, six core findings, 90-second limit, as their pages state | One public page, no signup, most severe finding, under a minute, capped at 45 seconds |
| Chat | Can open the widget and record the first message; a short test question only after you confirm you control the site | Reads widget text as the page first loads: it reads text inside chat-like frames among the first 25 frames on the page; does not open the conversation |
| Voice and avatars | Not stated on the pages checked | Checks for undisclosed voice and avatar widgets on the page entered |
| Images / media | Samples IPTC and XMP; paid advanced check looks at structural C2PA in sampled files (first 512 KB, no signature validation, as they state) | Reads IPTC and C2PA AI markers on up to eight images and flags those with no visible label. Partial Article 50(2) coverage: no watermark detection and no check of a provider's marking |
| Disclosure presentation | First interaction, mobile persistence, and language coverage (advanced) | Checks that the AI disclosure isn't hidden or tiny (under 10px), flags very low contrast (below 3:1), and checks it isn't hidden from screen readers via ARIA |
| Extra pages | Free: one homepage. Paid: up to 10, 100 or 500 pages depending on the plan | The page you enter only; not a site crawl |
| Paid, as of 12 November 2026 | Pro €20/month; Business €200/month; Evidence Pack €79 one-off (€49 for Pro members). First-time Pro and Business: 7-day trial; annual billing saves 17% | €499 one-off report, one free recheck within 30 days |
| Keeping a record | Sealed PDF with SHA-256 and HMAC; monitoring and change alerts on paid plans, on sites you confirm you control | Dated PDF with a unique report ID and a SHA-256 fingerprint that shows the file is unaltered, not that the site meets Article 50. Not a monitoring subscription |

When to choose DisclosureProof
Choose DisclosureProof if you need a dated evidence record, not only a list of findings.
It suits a team that wants the chat widget opened, a desktop and mobile view, media markings sampled, and — on paid plans — more pages, a sealed pack, or scheduled re-scans that email you when something changes. The free homepage scan, with six core findings and a 90-second limit, is the starting point their pages describe. The Evidence Pack is a second, deeper scan of up to 100 pages, not a PDF of the free result. Its changelog says rule pack 2026.13, dated 7 November 2026, now opens and reads iAdvize and Seamly chats. Monitoring runs on sites after you confirm you control them.
It is a weaker fit if you mainly want a first-view check of voice or avatar widgets, or a one-off fix report with paste-ready wording and no subscription. Their public pages do not state that they check voice agents or avatars, or that they measure contrast, size and ARIA the way Article50.io describes.
When to choose Article50.io
Choose Article50.io if you want to know what a first-time visitor can already see on one public page, including widgets that are not only chat.
Where DisclosureProof is built around evidence and monitoring, Article50.io is a one-off fix report: €499 once, no subscription. It lists every finding with remediation steps and paste-ready wording, and includes one free recheck within 30 days. The scan checks that the AI disclosure isn't hidden or tiny (under 10px), flags very low contrast (below 3:1), and checks it isn't hidden from screen readers via ARIA. It also flags a clear mismatch between the disclosure's language and the page's language. The free scan shows the most severe finding and is capped at 45 seconds. See product facts, pricing and a sample report.
It does not crawl tens or hundreds of pages, keep a monitoring watch, or open the widget to record a first message after click. It cannot hear a voice agent on a call. A clean result is not a clearance that you meet Article 50.
Frequently asked questions
These answers compare both products as their public pages described them on 12 November 2026.
What is the difference between Article50.io and DisclosureProof?
Both use a real browser. DisclosureProof can open the chat, check desktop and mobile, sample media markings, crawl further pages and keep a sealed evidence record, with optional monitoring. Article50.io checks one public page at first view — it does not open the chat — including voice and avatar widgets and disclosure presentation, under a minute, with a €499 report.
Does Article50.io open the chat widget?
No. It reads what is on the public page when it first loads, including text a chat, voice or avatar widget shows at first view, and it does not click, open the chat or pass a consent banner. DisclosureProof's pages say the free scan can open the widget and record the first message, without sending a question.
Which tool is better if I need a record I can keep?
DisclosureProof is built around a sealed, dated record and, on paid plans, scheduled re-scans with change alerts. Article50.io's €499 report is a one-off dated PDF with a unique report ID and a SHA-256 fingerprint. The fingerprint shows the file is unaltered, not that the site meets Article 50. It includes one free recheck within 30 days, not monitoring.
Does either tool crawl my whole website?
Article50.io scans the public page you enter, not the rest of the site. DisclosureProof's free scan is also one homepage; paid options add further pages, up to 10, 100 or 500 depending on the plan, as stated on its pricing page. Neither tool should be treated as a complete inventory of every URL you publish.
What is free on Article50.io and on DisclosureProof?
Article50.io's free scan shows the single most severe finding on one public page, under a minute and capped at 45 seconds, with no signup. DisclosureProof's free scan, with no account or card, grades six core findings on a homepage within a 90-second limit, as its pages state. Both say a result is not a legal clearance.
