Per-item preferences
Declare per post, page, or media (W3C TDMRep; IETF AIPREF coming).
Coming soon TDM Opt-out for WordPress
WordPress plugin to opt out of AI training
The Liccium WordPress plugin lets you declare AI preferences for your posts, pages, and media without leaving your WordPress dashboard. Each declaration is digitally signed, timestamped, and registered, so your preference is provable and machine-verifiable.
What it offers
What it does
Content-bound
The preference stays bound to the content, even if shared or altered.
Signed and timestamped
Signed by your site and independently timestamped (RFC-3161).
Publicly resolvable
Registered and resolvable on opt-out.directory.
Full version history
Update, supersede, or withdraw any declaration.
Privacy by design
Content is fingerprinted, then deleted immediately.
How it works
Install and connect, pick what to declare, declare
Install and connect once
Install the plugin and connect your site; it sets up your signing identity and credential.
Pick what to declare
Choose a post, page, or media, and set your preference.
Declare
Liccium generates the content fingerprint, signs and timestamps it, and registers it.
Why it’s different
Signed, timestamped, and defensible
A robots.txt entry or a bare TDMRep header is unsigned and unattributable – anyone can claim anything, and no one can prove who set it. Liccium declarations are signed, timestamped, and registered, so they can be verified and defended.
