    description
    Screenshots can be challenged in court. ProofSnap makes your evidence tamper-proof.
    
    One click captures any webpage as a blockchain-timestamped, digitally signed evidence package — court-ready under US Federal Rules of Evidence (FRE 901/902) and EU eIDAS Regulation 910/2014. 7-day free trial.
    
    🛡️ Why ProofSnap
    A regular screenshot can be forged in 30 seconds with browser DevTools. In *United States v. Vayner*, a federal court rejected a Facebook screenshot for lack of authentication. ProofSnap ensures your evidence holds up — with metadata, timestamps, chain of custody, and cryptographic proof.
    
    🛡️ Provenance Certificate — Anti-Deepfake
    Every capture includes a Provenance Certificate PDF proving evidence was captured live from a real browser, not AI-generated. Eight integrity checks verify device, time, DNS, and TLS. Meets proposed FRE 707 (2025) and EU AI Act Article 50 (August 2026).
    
    🔒 Five Layers of Protection
    Auto-refresh before capture · SHA-256 cryptographic hash · RSA-4096 digital signature · Bitcoin blockchain timestamp · EU eIDAS Qualified Timestamp (Enterprise/Company plans). Plus ISO/IEC 27037:2012 chain of custody and device integrity scoring.
    
    📦 Evidence Package Contents
    Full-page or visible-area screenshot, complete HTML, DOM text, forensic metadata (URL, timestamps, TLS, cookies), SHA-256 manifest with RSA-4096 signature, blockchain proof (.ots), tamper-evident forensic log, ISO 27037 chain of custody, Provenance Certificate PDF, court-ready evidence report. Self-contained ZIP.
    
    🎥 Optional Video Recording — Three Modes
    Auto (1-click, records the capture process), Manual (user-driven for media playback like livestreams or YouTube videos), Session (multi-tab continuous recording). All hashed, signed, and blockchain-timestamped alongside other files. For 30-min recordings with audio capture, see Video SnapPack below.
    
    🗂️ Session Capture — Multi-Tab Forensics
    Document an entire browsing session as a single evidence package. Every visited http(s) tab gets full-page screenshot, HTML, DOM text, DNS cross-verification (Google + Cloudflare DoH), WHOIS lookup, TLS info, per-tab chain of custody, and signed evidence.pdf. Session-wide screen recording bundled. Ideal for compliance audits, fraud investigation, journalism, and IP enforcement.
    
    📁 File Certification
    Drag-and-drop any file. Each gets SHA-256 hash, RSA-4096 signature, blockchain timestamp, and Provenance Certificate. Batch supported. Enterprise plans include eIDAS qualified timestamps. Files never leave your device — only hashes are sent.
    
    💰 Pay-Per-Use SnapPacks
    SnapPack — 10 evidence captures for $4.99. Credits never expire.
    
    eIDAS SnapPack — EU qualified timestamps without a subscription. 1 stamp $6.99, 5 for $24.99 ($5/stamp), 10 for $44.99 ($4.50/stamp). Credits valid 12 months. Legal presumption of accuracy across all 27 EU member states.
    
    🎬 Video SnapPack — Long-form video evidence (30 min + audio) with bundled eIDAS qualified timestamp. For livestreams, video calls, deepfake demos, multi-step transactions. Audio captured at Opus 64 kbps, qualified timestamp by Disig a.s. Buy 1 video $24.99, 3 for $59.99 ($19.99/video, save 20%), or 10 for $169.99 ($16.99/video, save 32%). Credits valid 12 months. Each pack also bundles regular snap credits + eIDAS stamps at 1:1 ratio.
    
    📱 Social Media & Messaging Forensics
    Optimized capture for WhatsApp Web, Telegram, Discord, Slack. Captures server-delivered content, not user-modified DOM. Full-page scroll or visible-area only (GDPR compliant).
    
    🤖 AI Accountability
    If a chatbot gives binding but incorrect advice, ProofSnap freezes the output with cryptographic proof. Essential for AI liability disputes and EU AI Act compliance.
    
    🧬 AI Image Detection
    Every captured image is scanned for AI-generation signals via six local, deterministic layers: C2PA Content Credentials (cryptographic provenance), Google SynthID portal link, IPTC 2025.1 AI properties (AISystemUsed, AI prompt), XMP DigitalSourceType, EXIF/PNG/zTXt metadata patterns (Stable Diffusion, Midjourney, DALL-E, Firefly), and AI gallery URL context (30+ vendors). Each image gets a perceptual hash (dHash) plus reverse-image-search links (Google Lens, TinEye, Yandex) printed in the evidence PDF. Pure on-device parsing — c2pa-js WASM + exifr, no cloud calls. C2PA 2.4 + IPTC 2025.1 compliant.

    Screenshots can be challenged in court. ProofSnap makes your evidence tamper-proof.
    
    One click captures any webpage as a blockchain-timestamped, digitally signed evidence package — court-ready under US Federal Rules of Evidence (FRE 901/902) and EU eIDAS Regulation 910/2014. 7-day free trial.
    
    🛡️ Why ProofSnap Exists
    A regular screenshot can be forged in 30 seconds using browser DevTools. In United States v. Vayner, a federal court rejected a Facebook screenshot for lack of authentication. Screenshots lack metadata, timestamps, and chain of custody — making them easy to challenge in insurance disputes, harassment cases, and IP enforcement. ProofSnap ensures your evidence holds up.
    
    🛡️ Provenance Certificate — Anti-Deepfake Protection
    Every capture automatically includes a Provenance Certificate — a standalone PDF proving your evidence was captured live from a real web browser, not AI-generated or manipulated. Eight independent integrity checks verify device authenticity, time sources, DNS resolution, and TLS certificates. Built for the deepfake era — meets proposed FRE 707 (2025) and EU AI Act Article 50 (August 2026) standards. No other self-service evidence tool offers this.
    
    🔒 Five Layers of Protection
    1. Auto-refresh before capture — eliminates client-side DOM manipulation
    2. SHA-256 cryptographic hash — any modification is instantly detectable
    3. RSA-4096 digital signature — proves the evidence was not altered
    4. Bitcoin blockchain timestamp — decentralized, independently verifiable proof of existence
    5. EU eIDAS Qualified Timestamp — legal presumption of accuracy across 27 EU member states (Enterprise and Company plans)
    
    Every package also includes a forensic chain of custody compliant with ISO/IEC 27037:2012 and device integrity scoring.
    
    📦 Every Evidence Package Contains:
    Full-page or visible-area screenshot, complete HTML source code, extracted DOM text, forensic metadata (URL, timestamps, TLS certificate, cookies), SHA-256 manifest with RSA-4096 digital signature, Bitcoin blockchain proof (.ots file), forensic log with tamper-evident hash chain, chain of custody document (ISO/IEC 27037:2012), Provenance Certificate PDF, and a court-ready evidence report. Exported as a portable, self-contained ZIP.
    
    🎥 Optional Video Recording — Three Modes
    Record screen activity as part of the evidence package — automatically hashed, signed, and blockchain-timestamped alongside all other files. Choose the mode that fits your workflow:
    
    • Auto — 1-click. Recorder runs during the capture pipeline only. Best for documenting that the capture itself was performed against a live browser.
    • Manual — 2-click. You start and stop the recorder. Ideal for capturing media playback such as a 5-minute YouTube video, livestream, or interactive demo before generating the evidence package.
    • Session — 2-click multi-tab. Records a continuous video while you browse across multiple tabs, then bundles everything into one signed evidence package (see Session Capture below).
    
    🗂️ Session Capture — Multi-Tab Forensics
    Document an entire browsing session as a single evidence package. Every visited http(s) tab gets its own forensic bundle — full-page screenshot, HTML source, DOM text, DNS cross-verification (Google + Cloudflare DoH), WHOIS lookup, TLS information, per-tab chain-of-custody document, and a signed per-tab evidence.pdf. A session-wide screen recording captures video playback across tabs (choose "window" or "screen" in Chrome's share prompt to record across all tabs). Ideal for compliance audits, fraud investigation, multi-platform journalism, IP enforcement, and any workflow where the evidence story spans more than one page.
    
    📁 File Certification
    Certify the existence of any file — drag and drop documents, images, contracts, or any digital asset. Each file receives a SHA-256 hash, RSA-4096 signature, Bitcoin blockchain timestamp, and a Provenance Certificate PDF. Batch certification supported. Enterprise plans include EU eIDAS qualified timestamps. Your file never leaves your device — only the cryptographic hash is sent to timestamp servers.

    🛡️ Why ProofSnap Exists
    A regular screenshot can be forged in 30 seconds using browser DevTools. In United States v. Vayner, a federal court rejected a Facebook screenshot for lack of authentication. Screenshots lack metadata, timestamps, and chain of custody — making them easy to challenge in insurance disputes, harassment cases, and IP enforcement. ProofSnap ensures your evidence holds up.
    
    🛡️ Provenance Certificate — Anti-Deepfake Protection
    Every capture automatically includes a Provenance Certificate — a standalone PDF proving your evidence was captured live from a real web browser, not AI-generated or manipulated. Eight independent integrity checks verify device authenticity, time sources, DNS resolution, and TLS certificates. Built for the deepfake era — meets proposed FRE 707 (2025) and EU AI Act Article 50 (August 2026) standards. No other self-service evidence tool offers this.
    
    🔒 Five Layers of Protection
    1. Auto-refresh before capture — eliminates client-side DOM manipulation
    2. SHA-256 cryptographic hash — any modification is instantly detectable
    3. RSA-4096 digital signature — proves the evidence was not altered
    4. Bitcoin blockchain timestamp — decentralized, independently verifiable proof of existence
    5. EU eIDAS Qualified Timestamp — legal presumption of accuracy across 27 EU member states (Enterprise and Company plans)

Exported as a portable, self-contained ZIP.
    
    🎥 Optional Video Recording
    Record the entire capture process as a video included in the evidence package — proving exactly what happened during evidence collection. The video is automatically hashed, signed, and blockchain-timestamped along with all other files. Enable with a single toggle before capture.

    Screenshots can be challenged in court. ProofSnap makes your evidence tamper-proof.
    
    One click captures any webpage as a blockchain-timestamped, digitally signed evidence package — court-ready under US Federal Rules of Evidence (FRE 901/902) and EU eIDAS Regulation 910/2014. 7-day free trial.
    
    🛡️ Why ProofSnap Exists
    A regular screenshot can be forged in 30 seconds using browser DevTools. In United States v. Vayner, a federal court rejected a Facebook screenshot for lack of authentication. Screenshots lack metadata, timestamps, and chain of custody — making them easy to challenge in insurance disputes, harassment cases, and IP enforcement. ProofSnap ensures your evidence holds up.
    
    🛡️ Provenance Certificate — Anti-Deepfake Protection
    Every capture automatically includes a Provenance Certificate — a standalone PDF proving your evidence was captured live from a real web browser, not AI-generated or manipulated. Eight independent integrity checks verify device authenticity, time sources, DNS resolution, and TLS certificates. Built for the deepfake era — meets proposed FRE 707 (2025) and EU AI Act Article 50 (August 2026) standards. No other self-service evidence tool offers this.
    
    🔒 Five Layers of Protection
    1. Auto-refresh before capture — eliminates client-side DOM manipulation
    2. SHA-256 cryptographic hash — any modification is instantly detectable
    3. RSA-4096 digital signature — proves the evidence was not altered
    4. Bitcoin blockchain timestamp — decentralized, independently verifiable proof of existence
    5. EU eIDAS Qualified Timestamp — legal presumption of accuracy across 27 EU member states (Enterprise and Company plans)
    
    Every package also includes a forensic chain of custody compliant with ISO/IEC 27037:2012 and device integrity scoring.
    
    📦 Every Evidence Package Contains:
    Full-page or visible-area screenshot, complete HTML source code, extracted DOM text, forensic metadata (URL, timestamps, TLS certificate, cookies), SHA-256 manifest with RSA-4096 digital signature, Bitcoin blockchain proof (.ots file), forensic log with tamper-evident hash chain, chain of custody document (ISO/IEC 27037:2012), Provenance Certificate PDF, and a court-ready evidence report. Exported as a portable, self-contained ZIP.
    
    🎥 Optional Video Recording
    Record the entire capture process as a video included in the evidence package — proving exactly what happened during evidence collection. The video is automatically hashed, signed, and blockchain-timestamped along with all other files. Enable with a single toggle before capture.
    
    📁 File Certification
    Certify the existence of any file — drag and drop documents, images, contracts, or any digital asset. Each file receives a SHA-256 hash, RSA-4096 signature, Bitcoin blockchain timestamp, and a Provenance Certificate PDF. Batch certification supported. Enterprise plans include EU eIDAS qualified timestamps. Your file never leaves your device — only the cryptographic hash is sent to timestamp servers.
    
    💰 SnapPack — Pay Per Capture
    Don't need a monthly plan? Buy 10 evidence captures for $4.99 — no subscription, no commitment. Credits never expire. Includes full evidence package with blockchain timestamps. Buy more anytime.

About

Screenshots can be challenged in court. ProofSnap makes your evidence tamper-proof.

One click captures any webpage as a blockchain-timestamped, digitally signed evidence package — court-ready under US Federal Rules of Evidence (FRE 901/902) and EU eIDAS Regulation 910/2014. 7-day free trial.

§ Why ProofSnap
A regular screenshot can be forged in 30 seconds with browser DevTools. In *United States v. Vayner*, a federal court rejected a Facebook screenshot for lack of authentication. ProofSnap ensures your evidence holds up — with metadata, timestamps, chain of custody, and cryptographic proof.

◆ Provenance Certificate — Anti-Deepfake
Every capture includes a Provenance Certificate PDF proving evidence was captured live from a real browser, not AI-generated. Eight integrity checks verify device, time, DNS, and TLS. Meets proposed FRE 707 (2025) and EU AI Act Article 50 (August 2026).

▪ Five Layers of Protection
Auto-refresh before capture · SHA-256 cryptographic hash · RSA-4096 digital signature · Bitcoin blockchain timestamp · EU eIDAS Qualified Timestamp (Enterprise/Company plans). Plus ISO/IEC 27037:2012 chain of custody and device integrity scoring.

▣ Evidence Package Contents
Full-page or visible-area screenshot, complete HTML, DOM text, forensic metadata (URL, timestamps, TLS, cookies), SHA-256 manifest with RSA-4096 signature, blockchain proof (.ots), tamper-evident forensic log, ISO 27037 chain of custody, Provenance Certificate PDF, court-ready evidence report. Self-contained ZIP.

▶ Optional Video Recording — Three Modes
Auto (1-click, records the capture process), Manual (user-driven for media playback like livestreams or YouTube videos), Session (multi-tab continuous recording). All hashed, signed, and blockchain-timestamped alongside other files. For 30-min recordings with audio capture, see Video SnapPack below.

※ Session Capture — Multi-Tab Forensics
Document an entire browsing session as a single evidence package. Every visited http(s) tab gets full-page screenshot, HTML, DOM text, DNS cross-verification (Google + Cloudflare DoH), WHOIS lookup, TLS info, per-tab chain of custody, and signed evidence.pdf. Session-wide screen recording bundled. Ideal for compliance audits, fraud investigation, journalism, and IP enforcement.

▫ File Certification
Drag-and-drop any file. Each gets SHA-256 hash, RSA-4096 signature, blockchain timestamp, and Provenance Certificate. Batch supported. Enterprise plans include eIDAS qualified timestamps. Files never leave your device — only hashes are sent.

◈ Whitelabel Branding
Replace ProofSnap branding on evidence PDFs with your own logo, organization name, and brand color. Available on Enterprise and Company plans, plus any eIDAS SnapPack or Video SnapPack purchase. Ideal for law firms, agencies, and compliance teams delivering branded evidence to clients.

Optimized capture for WhatsApp Web, Telegram, Discord, Slack. Captures server-delivered content, not user-modified DOM. Full-page scroll or visible-area only (GDPR compliant).

⚙ AI Accountability
If a chatbot gives binding but incorrect advice, ProofSnap freezes the output with cryptographic proof. Essential for AI liability disputes and EU AI Act compliance.

⌬ AI Image Detection
Every captured image is scanned for AI-generation signals via six local, deterministic layers: C2PA Content Credentials (cryptographic provenance), Google SynthID portal link, IPTC 2025.1 AI properties (AISystemUsed, AI prompt), XMP DigitalSourceType, EXIF/PNG/zTXt metadata patterns (Stable Diffusion, Midjourney, DALL-E, Firefly), and AI gallery URL context (30+ vendors). Each image gets a perceptual hash (dHash) plus reverse-image-search links (Google Lens, TinEye, Yandex) printed in the evidence PDF. Pure on-device parsing — c2pa-js WASM + exifr, no cloud calls. C2PA 2.4 + IPTC 2025.1 compliant.
