Overview
Create web pages snapshots that are cryptographically proven
Record proof of any web page. This extension makes a snapshot of the web page, as you see it, and creates a cryptographic proof that is timestamped. Your proof remains private, and you can download it from the extension's side panel, in a .json file that can be viewed with the extension at any time. You must download this file if you want to save your proof! You can select how much information you want included - from just the HTML, to network requests happening in the background, and screen capture. By default, HTML, scripts, and network requests are sanitized to eliminate sensitive authentication information when you are logged into the website you want to capture, but this extension cannot guarantee that all sensitive information has been redacted. It is your responsibility if you make the proof content public. This data is cryptographically hashed to produce a 32-byte identifier for your data(data ID). This identifier is sent to our Kayros indexer, which makes a timestamped record and returns a cryptographic hash (record ID). This record ID is proof that the web page was recorded at that moment in time. Kayros only receives your data identifier. Your full information submitted in the form is kept private, and you must download your .json file to store it on your computer or send it to someone else. If you want to prove your digital actions, use our provable.dev tools. If you encounter issues, let us know at kuip.ltd.open@gmail.com and send us the link to the form that you tried, and if possible, describe what the issue is (otherwise, we may not be able to help).
