The demo lets you:
- Sign a file using a leased isolated model
- Verify it later
- Revoke the signing authority
- See, in real time, how trust and verification change
This is intentionally a research demo, not a finished product. By trying it out, breaking things, and sharing feedback, you’re actively helping us learn what’s useful, what’s confusing, and what might be worth turning into a real product.
Why we’re exploring this?
Digital signatures are usually permanent, key-based, and all-or-nothing. We wanted to explore something different:- Signatures that are revocable by design
- Verification tied to isolated models, not long-lived keys
- Authenticity without handing custody of your data to a third party
Where could this go?
This demo represents just one possible direction. Some potential product paths we’re actively thinking about include:- First-party content verification - Proving you authored a piece of content — without publishing or storing the original file.
- Third-party endorsement and verification - Allowing an organization, brand, or authority to endorse or validate content created by someone else — and revoke that endorsement later if needed.
- AI content attestation - Proving content was AI-generated, which model generated it, and who the model belonged to while avoiding watermark fragility, centralized registries, or irreversible claims.
- Digital asset integrity & provenance - Verifying that file or digital assets haven’t changed over time, provide important metadata about the asset, and clearly surfacing when trust no longer applies.
If you’re curious, skeptical, or just want to see something a little different, we’d love for you to try the demo and tell us what you think. Help us explore what comes next.
