Use cases — start with your situation.

Competitor copied your listing →Prove stolen product photos or copied listing text for an unfair-competition claim.

Neighbour disputes →Document harassment, threats, and group-chat messages.

Email evidence →Prove an email was sent or received at a specific time.
Workplace harassment →Preserve Slack, Teams, and email before HR locks access.

Landlord-tenant disputes →Preserve listings, messages, and property condition records.
IP & trademark infringement →Certify infringing pages before the seller removes them.
Insurance claims →Document damage with timestamped photos and videos.

How-to guides — start with your content type.

Each guide explains the correct way to capture a specific content type as legal evidence. Use this if you know what you need to capture but not which evidence package fits.

Certify a website →Full-page capture of any public webpage, URL-bound and timestamped.
Certify a social media post →Facebook, Instagram, X, LinkedIn, TikTok — by URL or session.
Certify an email →Webmail capture or .eml file certification.
Prove you received an email (Gmail) →Recorded session showing the message, its DKIM signature, and the HAR proving real Gmail servers.
Bailiff vs InstantProof →The same court-usable proof of online content as a bailiff — about €10 instead of €300–700.
Is this image AI-generated? →Free in-browser check — detector score + Content Credentials, honest about the limits.
Record WhatsApp Web →Browser Session recording of WhatsApp Web with full conversation.
Certify a WhatsApp export →Turn a full WhatsApp chat export into a timestamped, signed transcript PDF.
Certify a file or document →Any file up to 100 MB hashed, timestamped, and signed.
