Features and specs

What each product offers, as listed by its team.

Obsidian 6 features
Gelt.dev 5 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.
  • 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.
  • Free to use
    Gelt.dev offers its core calculators and tools without charge, making it accessible for individuals who want to estimate equity compensation, taxes, or other financial scenarios without paying for a subscription service.
  • Focused on equity compensation
    The platform appears to specialize in helping users understand and calculate equity compensation details such as stock options, RSUs, and related tax implications, which is a niche but valuable use case for tech employees.
  • Simple, user-friendly interface
    The tool is designed with a straightforward, easy-to-navigate interface that allows users to quickly input data and receive calculations without a steep learning curve.
  • Useful for tech employees
    Given its focus on equity compensation, Gelt.dev is particularly useful for employees at startups and tech companies who receive stock-based compensation and need to understand its value and tax impact.
  • Quick calculations
    Users can get fast estimates for complex financial scenarios like vesting schedules or tax liabilities without needing to consult a financial advisor for basic questions.

Possible disadvantages

  • Limited scope
    The tool may only cover specific financial scenarios like equity compensation, making it less useful for broader financial planning needs such as retirement planning, investment management, or general budgeting.
  • Not a substitute for professional advice
    While useful for quick estimates, the calculations provided may not account for individual complexities in tax situations, and users may still need to consult a CPA or financial advisor for accurate, personalized guidance.
  • Potential accuracy limitations
    Automated calculators like this may not always reflect the most current tax laws or company-specific equity plan details, potentially leading to estimates that don't perfectly match real-world outcomes.
  • Limited brand recognition
    As a smaller or newer platform, Gelt.dev may not have the same level of trust, reviews, or track record as more established financial planning tools, which could make some users hesitant to rely on it.
  • Possible lack of customer support
    Smaller platforms often have limited customer service options, so users encountering issues or needing clarification on results may struggle to get timely help.
