Prove that you said things before anyone else
About yousaidthat.org
YouSaidThat.org offers a innovative way for individuals and professionals to securely seal and verify their predictions, statements, or market calls using advanced cryptographic standards. By leveraging SHA-256 hashing, AES-256-GCM encryption, and RFC 3161 timestamps, users can prove they made a specific statement at a particular moment without revealing its content until they choose to do so. This ensures the integrity and authenticity of their predictions, whether for financial markets, content creation, or personal assertions, all without the need for accounts or centralized servers. Built on open cryptographic standards, it provides a transparent, auditable, and trustless proof system that lives outside any server infrastructure. Its simplicity and focus on privacy make it especially appealing for journalists, traders, developers, and influencers who want to establish credibility and prevent disputes over their statements.

Pros
- ✓Utilizes robust cryptographic standards for security and trustlessness
- ✓No accounts or registration required, ensuring privacy and simplicity
- ✓Provides publicly verifiable proof that is tamper-proof
- ✓Open standards guarantee transparency and interoperability
- ✓Suitable for a wide range of use cases from market predictions to content claims
Cons
- ✗Lacks a user interface or automation tools, which may limit ease of use for some users
- ✗No integrated storage or cloud backup options, relying solely on cryptographic proof
- ✗Potentially complex for non-technical users unfamiliar with cryptography
Use Cases
Pricing
Likely free to use, as the tool relies on open cryptography and public verification methods. There may be premium features or integrations in the future, but currently it appears to be a free, open standard implementation without paid plans.
