Features and specs

What each product offers, as listed by its team.

RedactProof 7 features
Obsidian 6 features
  • Redaction happens in your browser
    Documents are processed on your own device. Nothing is uploaded, so there is no server copy to leak, subpoena or breach.
  • Finds personal data for you
    Automatic detection of names, addresses, dates of birth, emails, phone numbers, NI and NHS numbers, and other identifiers, ready for you to review and confirm.
  • Real removal, not a black box
    Redactions strip the underlying text, images and metadata from the file. There is nothing under the box to copy, search or recover.
  • Redaction Checker
    Test any redacted PDF, including ones made elsewhere, to see whether the hidden text is still recoverable.
  • Verification certificates
    Each export can carry a certificate proving what was removed and when, backed by a hash of the file. Anyone can check it without seeing the document.
  • Built for SARs, DSARs, FOI and disclosure
    Made for the people who redact for a living: DPOs, paralegals, HR, public sector and legal teams working to GDPR, UK GDPR, HIPAA and FOI deadlines.
  • Bulk and audit trail on paid tiers
    Batch processing, approval workflows and an audit log for teams that need to show their working.
  • Local-first
    Obsidian stores your notes locally on your device, giving you full control over your data and enhancing privacy.
  • Markdown Support
    Obsidian uses Markdown, making it easy to format text and compatible with many other text editors and tools.
  • Bidirectional Linking
    You can create bidirectional links between notes, which helps in building a knowledge graph and navigating related information more easily.
  • Customizability
    Obsidian is highly customizable with community plugins, themes, and various settings to fit different workflows.
  • Graph View
    Provides a visual graph view of your notes and their connections, aiding in understanding relationships and discovering insights.
  • Offline Access
    Since the notes are stored locally, you can access and edit them without an internet connection.

Possible disadvantages

  • Learning Curve
    Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.
  • Sync Limitations
    While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.
  • No True Real-time Collaboration
    Obsidian lacks native real-time collaboration features, making it less suitable for collaborative work compared to cloud-based solutions.
  • Limited Mobile Features
    The mobile version of Obsidian, while functional, is not as robust as the desktop application, potentially hindering productivity on the go.
  • Dependence on Plugins
    Many advanced features require the use of third-party plugins, which could lead to compatibility issues and reliance on community support.
  • Performance on Large Vaults
    Performance might degrade with a very large number of notes or complex graphs, impacting usability.

  • How can software developers stay motivated at work?
    For note-taking, I recommend Obsidian. It's lightweight, has a large community, and offers plenty of useful plugins. I use the Timekeep plugin myself, which helps me connect tasks with the time spent on them. - Source: dev.to / 12 days ago
