Features and specs

What each product offers, as listed by its team.

Obsidian 6 features
ActivitySmith 4 features
  • 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.

    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.

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.
  • Push Notifications
    Send Push Notifications from Any Backend. Reach your own and your team’s devices with a single API call.
  • Live Activities
    Track deployments, automations, cron jobs, AI agents working, and business numbers in real time on your Lock Screen.
  • Lock Screen Widgets
    Display any value on your Lock Screen with widgets - SaaS metrics, revenue, number of users, uptime, or anything else you want to track.
  • MCP server for AI agents
    Let your AI agents report back to your iPhone, so so that they can notify you when work is done, blocked, or ready for review, and keep longer tasks visible with a Live Activity on your Lock Screen.
