  • Limited Step-by-Step Guidance
    There is little to no step-by-step guidance or hints available, which might hinder the learning process for some users.
  • Focus on Mathematics
    The heavy focus on mathematical problems may not appeal to those primarily interested in practical programming tasks.
  • Lack of Immediate Feedback
    The platform does not offer immediate feedback on code submissions, which might slow down the learning process.
  • No Built-in IDE
    Users need to use their own development environments, which might be inconvenient for some, especially beginners.

Obsidian features and specs

  • 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.

  1. The kind of software that may change your life

    Perhaps you know someone who swears by Obsidian, it may seem like a cult of overly devoted people for how passionate they are, but it's not without reason

    I've been using Obsidian for over 3 years, at a point in my life when I felt I had to handle too much information and I felt like grasping water not being able to remember everything I wanted, language learning, programming, accounting, university, daily tasks. A friend recommended it to me next to Notion (of which he is a passionate cultist priest) and I reluctantly picked it and fell in love almost immediately.

    Obsidian seems very simple, like a notepad with folder interface, similar to Sublime Text, but the ability to link files together in a Wiki style allows you to organize ideas in any way you want, one file may lead to a dozen or more ideas that are related

    If you want to do something specific, Obsidian has a plethora of community created plugins that expand the functionality, in my case, I use obsidian to organize my classes both as a teacher and as a student, using local databases, calendars, dictionaries, slides, vector graphic drawings, excel-like tables, Anki connection, podcasts, and more

    Competitors: Notion, Evernote
    Pros:    Awesome community|Custom plugins|Local hosting|Beautiful themes|Highly customizable|Cloud storage|Becomes more useful over time|Markdown support
    Cons:    Seems complicated/complex at first|Takes time to set up your personal workspace|Overwhelming for first time user

    My personal knowledge-base of choice

    I've been using Obsidian for more than a year. It's been great. I think it offer a great balance of control, flexibility and extensibility. What is more, you own your own data, that's been a must-have feature for me. I just can't imagine putting all my knowledge into something that I don't have control over.

    I think two of the most popular alternatives that people consider are Logseq and Roam Research. Although Logseq is a bit different, it's considered compatible with Obsidian. Supposedly, you can use them with a shared database (files. Both use simple text files for storage). I tried that once, a few months ago. It worked, yet it messed up a bit my Obsidian files ¯_(ツ)_/¯.

The 6 best note-taking apps in 2024
One thing to note: Notion bills itself as an Evernote competitor for personal users. It can be—but it's too much for most people, and its offline functionality isn't the best. If you love the idea of Notion, go right ahead and try the free Personal Plan, but for me, it's really best as a team notes app or an AI-powered notes app. Something like Obsidian (which we'll look at...

For a consumer coming from Evernote, Notion, OneNote, or a similar product, we would advise trying Obsidian along another product on this list as it has the largest learning curve.

  • Which Markdown editor to choose
    Inline preview, usually called WYSIWYG. Obsidian's Live Preview mode hides the syntax except where the cursor is. Obsidian is a far better personal knowledge base than anything else on this page, with backlinks, a graph and years of plugins, and if that is what you need the question of what its editor is called does not matter much. - Source: dev.to / 15 days ago
