About Proofsnap and Linkman

In their own words, as submitted to SaaSHub.

Proofsnap
Linkman

ProofSnap preserves a web page, social media post or chat as a signed evidence package.

Features and specs

What each product offers, as listed by its team.

Proofsnap 5 features
Linkman 5 features
  • Signed evidence package
    Every capture becomes a package of 11 to 15 files: full-page screenshot, page source, extracted text, metadata, HTTP headers, DNS and WHOIS records, with a SHA-256 hash of every file and an RSA-4096 signed manifest.
  • Independent timestamps
    The manifest hash is anchored in Bitcoin via OpenTimestamps on most plans, and an eIDAS qualified timestamp from a Qualified Trust Service Provider on the EU Trusted List is optional.
  • Offline verification without the vendor
    Anyone, including the other side, can check the hashes, signature and timestamps offline with the bundled scripts or the open-source verifier, without relying on ProofSnap.
  • Chat and AI conversation capture
    Captures full conversations in WhatsApp Web, Telegram, Discord and Slack, and chats in ChatGPT, Gemini and Claude, including the parts that need scrolling.
  • Multi-tab sessions with video
    Records a browsing session across several tabs, with a separate forensic snapshot of each visited tab and a session video, all in one signed package.
  • Organization
    Linkman offers advanced organizational features like keywords, descriptions, and ratings, allowing users to efficiently manage and categorize their bookmarks.
  • Search Functionality
    It has a powerful search capability that allows users to quickly find bookmarks based on various criteria, speeding up the retrieval process.
  • Cross-Browser Support
    Linkman supports multiple browsers, making it a versatile tool for users who work across different web environments.
  • Backup and Sync
    Users can easily back up and synchronize their bookmarks, ensuring data is kept safe and accessible across different devices.

Questions & Answers

As answered by people managing Proofsnap and Linkman.

Which are the primary technologies used for building your product?

Proofsnap's answer

ProofSnap was built in Dubai and is registered in Sharjah (SHAMS). It started from a simple observation: online content that matters in a dispute is usually saved as a screenshot, and a screenshot is the easiest kind of record to challenge. ProofSnap captures the page together with the cryptographic proof of what was captured and when, so the record can be checked rather than argued about.

Why should a person choose your product over its competitors?

Proofsnap's answer

Verification does not depend on a vendor portal or account: the other side can check the hashes, signature and timestamps offline with standard tools. ProofSnap also covers what many web capture tools skip: full chat conversations (WhatsApp Web, Telegram, Discord, Slack, ChatGPT, Gemini, Claude), multi-tab sessions with video, and an optional eIDAS qualified timestamp. It works as a browser extension with no setup, and a one-off SnapPack is available for people with a single matter.

How would you describe the primary audience of your product?

Proofsnap's answer

Lawyers and paralegals, private and corporate investigators, OSINT researchers, journalists, compliance and HR teams, brand protection teams, and individuals who need to preserve online content (posts, profiles, listings, chats) before it is edited or deleted.

What makes your product unique?

Proofsnap's answer

Every capture is a self-contained evidence package that anyone can verify without us. The package holds the screenshot, page source, metadata, HTTP headers, DNS and WHOIS records, a SHA-256 hash of every file, an RSA-4096 signed manifest and an independent timestamp, and it ships with verification scripts and an open-source verifier. If ProofSnap disappeared tomorrow, the packages could still be checked.
