Why did 2 clauses fail?
Verification works by searching for the exact clause text inside the TOS document. A clause fails when the wording does not match character-for-character. Common reasons: the company quietly updated their terms, the AI slightly paraphrased when extracting, or the clause lives in a separate linked document (like a privacy policy or data processing agreement). Failed clauses are flagged as “AI-extracted” on the site until they can be re-verified.
How this works
Stored on Arweave
The proof data is uploaded to Arweave, a permanent storage network. Once there, it cannot be changed or deleted by anyone - not even CrazyTOS.
Registered on AO Computer
Each verification is also registered on AO, a decentralized computer built on Arweave. Think of it as a public ledger: every verified clause gets an entry that anyone can check, creating a tamper-proof chain of records independent of any single company.
Why it matters
Companies change their terms all the time. This system creates a permanent, public record of what they said and when. If a clause disappears tomorrow, the proof still exists.
