i like logseq as somewhat modern iteration of org-mode
account-5•5h ago
What lead you to choose that over say obsidian, notion, Joplin, and the many others that pretty much do the same thing?
innocentoldguy•4h ago
I switched from Obsidian to Logseq because Logseq has better block-level support, better embedded image previews, and more functionality out of the box without having to rely on plugins

Why not Notion or Joplin? I like Logseq's outline format better than Joplin's long-form note taking format, and I just don't like Notion at all for purely subjective reasons.

jcynix•4h ago
Orgmode is more than just a note keeping tool, it is a complete and complex toolbox. I can use tables like a spreadsheet, include source code snippets, etc.

Joplin is fine, especially for shared note keeping. We store its notes on a private WebDAV server and everyone in the family can access these notes from their laptops or mobile devices.

But the editing capabilities of Joplin are dismal. Try to swap lines (on a smartphone, no mouse), change the same term in a number of notes, or do some more complex editing operations. These are easily done in emacs/orgmode, even on a smartphone or tablet ... ,at least with emacs running in Termux under Android.

solarkraft•2h ago
They do not do the same thing.

Logseq is an outliner (though it does have a document mode), which means a deep interaction with the document‘s hierarchy: You can zoom into blocks, collapse them (not ephemerally, it’s saved in the document) and link to them.

I’d probably use Obsidian if it had those features (since Logseq is still as buggy as it was years ago), but the last time I checked it did not.

uludag•5h ago
I'm on my seventh year of using org-mode for my task management. My system has slowly evolved over time but I'm pretty much still using the same single text file to manage everything. My main getting-things-done org-mode file is now at 6k lines long.

Before org-mode, I was always downloading different software to manage tasks and notes. The tool churn was very degrading to my productivity but I feel that commercial interests would keep turning the churn machine: new UI changes, enshitification, monthly subscriptions, etc.

It's such a refreshing feeling, sitting back, and feeling assured that for the next presumably 25 years of my career, and perhaps for the rest of my life, I can still be using org-mode, and it will always work as I learned it, but it's flexible enough to easily implement extensions.

lycopodiopsida•3m ago
I try it regularly and I was running an org-mode based task management for a year and some months in between, but man, I do not have time and patience for sync conflicts in 2025. It can work but I have to be very cautious, and iCloud sync being a bit mysterious does not help. But I've also recognized that I don't have very complex projects, that GTD tools do not matter since their contents are transient by nature and that Apple Reminders is basically good enough. As a bonus it allows me to share Lists/Projects with my wife.
thecsw•5h ago
Orgmode got me through college, research, and at work, it really is the perfected markup language that can do a lot more than just being a markup language. The extensibility and out of the box export to other formats makes it immediately useful for at least 80% of common tasks.

It has ingrained itself so deeply into my muscle memory that I built out a whole website builder [1] and extended the language to support all kinds of nice QoL things for my website [2].

Something that as the other commenter here noted—I can rely on orgmode for many decades to come.

jhoechtl•4h ago
I have on gripe, that is the mixture between org structure and org document heradings. I know, they are the same, and such a distinction doesn't exist.

You can start a "document" at any place in the org hierachy. I would rather prefer a distintion between these two concepts.

eviks•2h ago
> As of 2025-02, there is no formal Org-mode syntax definition.

is very far away from perfection

With regards to your 80% claim, do you happen to know an extension that works well with pasting images from clipboard?

Over the years, my professional note taking has become extremely reliant on quickly pasting images (most often screenshots from papers or quick-and-dirty plots I made myself) from clipboard directly into the notes. The friction of doing this in vanilla org-mode is the only reason I'm not doing everything in org-mode.

v9v•23m ago
I use org-download (https://github.com/abo-abo/org-download) for pasting images.
Nesco•5h ago
To people using org mode, how does it help you more than Markdown? Genuinely curious because I tried at some point and it felt too heavy.

Maybe because I am a vim user instead of eMacs?

stevekemp•4h ago
First of all "emacs" rather than "eMacs".

But to answer your main question, markdown is used for writing text which can then be converted to HTML, PDF, etc, etc. It's used just to format things. org can be used in that way, and it might feel better/worse depending on what you feel about the choices used for various formatting styles.

However the big gain of org is that you can use it to format dynamic tables, handle todo-lists, have deadlines, recurring tasks, etc, etc. It makes no sense to compare org-files with markdown-files. It's like saying "I use notepad how does Excel help you do more?" - they do different thigns.

Now, much like excel, most people don't do everythign with org, but they can if they want to. It is extraordinarily flexible, and can be extended with custom lisp code if necessary.

I track rental properties with an org-document for each property, and I get per-year profit/loss statements in a neat format with graphs too. You can't do that with markdown.

impulsivepuppet•4h ago
Org mode offers so much more than just syntax. You can use org files as a calendar, a todo/issue tracker with time accounting, a diary/knowledge base (zettelkasten, org-roam), as a literate programming tool (think jupyter code notebooks but for practically any programming language with org-babel), or a publishing tool (static site generator, latex/pdf export) all at the same time.

To be quite frank, Org mode is a lifestyle which existed long before Notion or Obsidian did. Saying that it has a barrier to entry is a bit of an understatement.

Having said all that, quite ironically, I've migrated over to Obsidian because I started using Intellij more for work, meaning that I don't need Emacs for its other capabilities all that much.

jcynix•4h ago
Markdown is a markup tool, i.e. you decorate your text. Orgmode on the other hand is a complete toolbox where you can add tags to notes, filter on these tags, manage calendars, etc. You can enter tables both for formatting and spreadsheet like calculation.

And you can insert snippets of code into your notes, like

    #+BEGIN_SRC shell
       ls | wc -l
      find . -type f -name "*foo*" 
    #+END_SRC
(or javascript, elisp, html, ... instead of shell) where the markup is changed appropriately in these regions.

You can even augment orgmode with elisp code if you are so inclined.

myaccountonhn•3h ago
I don't use it anymore but org-babel allows you to execute commands in code blocks. I would use that to build interactive explorations when learning how APIs work for example. I didn't find that nearly as seamless with Markdown.

Combined with org-agenda you also unlock a calendar with recurring events, task priorities and more.

MoreQARespect•1h ago
Orgmode has standardized primitives for the things which exist in some markdown note taking implementations but differ from implementation to implementation.

Markdown doesn't have a built in concept of todo or tag or scheduled event, for instance. It wasn't built for that.

I hate emacs but orgmode is still the file format which contains all of the primitives I need for my notes which looks like it will have the most staying power. I hope to be able to edit the same files in 2035 using whatever brain-connection device everybody is using in the future that I used in 2015 running on a netbook with 1GB of RAM.

Markdown files from the note taking flavor of today will have to be migrated somehow.

polivier•5m ago
`org-mode` used with Emacs is the tinkerer's dream playgound. Apart from the basic markdown stuff, there are so many wild things you can do. For example, org code blocks are not just the basic markdown code blocks that show formatted code. Org code blocks can actually be executed and can show the output of the code, inline. So you can write code blocks (that may include data found in variables/tables/etc elsewhere in the org file), then "refresh" your org file and all the inline outputs of the code blocks will be updated.
NoboruWataya•3h ago
I hear so many people rave about orgmode on HN, all of them emacs users. This seems obvious since it is an emacs feature after all, but if orgmode is so good, has it not been implemented outside of emacs? Is there a standalone orgmode implementation that non-emacs users should look into?
doctor_blood•3h ago
What would be the point? Without emacs all you're left with is another markup language.
sligor•2h ago
What makes org mode tied to emacs ? I really need to try org mode to understand it. If only I had time...
Torwald•1h ago
Elisp, but not really elisp, more the environment of elisp. It's a LISP machine. Hard to explain, it's a different way of computing. Another living instance of this model of computing is a Smalltalk image. Others have written about how LISPing makes you a better coder much better than I could. Try it out!
codethief•56m ago
I disagree, Elisp doesn't tie org to Emacs at all. What does tie org to Emacs is the fact that Emacs' org-mode (i.e. the mode you use to edit org files) provides a great DevEx when editing org files, including lots of convenience shortcuts. (Again, the fact that those are written in Elisp is irrelevant.)
skydhash•36m ago
It does. A lot of advanced options in Org have escape hatches for more code, and the fact that you configure org in Elisp and are free to hack on org provided functions due to the Elips environment add to its versality.
skydhash•40m ago
It’s really integrated into emacs.

First, you have the calendar, but it’s not just a date picker, it’s also shows holidays and other markers.

Then you have the capture (quick entry) where you have the full power of emacs environment plus lisp language to code anything you want. Emacs have other applications like a file manager, mail readers, document readers…, and you can capture the context as well as the note itself.

Then, there’s the agenda, which is fully customizable with a mix of options and code.

And there’s the exporters. Notice that emacs have support for most of the format, so it’s more like an handover to some other parts of emacs. But you don’t merely transform the document from org to html as an example. You extract the html from the org structure as you can filter sections out. Also a lot of options there (and code)

And code blocks (named babel). That you can execute.

So org can be a static document format or a dynamic environment. And all of that because of emacs as the buffer concept is very fluid. In emacs there are only buffers. Each buffer is assigned a major mode which is just a set of functions that does stuff on the buffer text. And you have the minor modes (more functions) that are more like plugins. And you’re free to hack on them. It’s just that the default set looks like a text editor.

pbmonster•17m ago
As a very practical example: You take notes in org-mode, and as you do in many modern note-taking apps, you use copious links between notes.

But org-mode is inside Emacs, and Emacs is (can be) also your email client. So your notes can link to emails. Emacs is also your calendar. So your notes can link to events.

You can extend this to almost anything if you like Emacs enough. Your notes link to source code files (or your notes contain code, which can be executed from your notes). Emacs is also your git front end, so you could link to commits.

ubermonkey•32m ago
I think you're missing what he's asking.

Orgmode includes agendas and whatnot in addition to the markup; any Org implementation somewhere else would need to include those.

stevekemp•2h ago
There is an implementation for neovim, and some "viewer" applicatrions for android, etc:

https://orgmode.org/tools.html

Basics are easy to replicate, but one of the reasons why org is so useful is because it is tied into the emacs ecosystem, so you can write extensions/configuration tweaks in lisp. You can hookup agenda (calendars), etc, etc, and those things don't really translate so well to external tools.

If you had to write a lisp interpreter, and fake "bare minimum" compatability? At that point you'd be better off just running emacs for real.

amelius•2h ago
> You can hookup agenda (calendars), etc, etc, and those things don't really translate so well to external tools.

Sounds like a replication of Unix inside an editor if you ask me.

vslavkin•1h ago
Well, yes. I'd say that's what emacs is. A framework for, mostly, text based applications in lisp. The advantage is its "unified interface".

Everything is configured in the same language, uses mostly the same keybinds, and can easily be integrated with other apps of the framework.

anthk•53m ago
If every Unix tool outputed TSV, yes. In Emacs everything it's Elisp.
pydry•2h ago
orgzly revived for android is pretty great.

more tooling would be good though, especially command line tools to get data in and out.

bananapub•2h ago
1. it has, there's various mobile apps and a reimplementation for vim and vscode at least

2. it's very very good and having access to it is enough reason for some people to become emacs users, much like magit

nurumaik•2h ago
Standalone orgmode implementation is called emacs with org mode. I'm that person that uses emacs solely for orgmode and write code in other editors (vscode/zed/cursor), we also exist
thyristan•1h ago
Same. I do use emacs with spacemacs, because that is the only thing that makes emacs viable to me, only to use it solely for orgmode.

Everything else happens in vim/nvim or zed.

eadmund•2h ago
> if orgmode is so good, has it not been implemented outside of emacs

Org Mode is that good, but part of its goodness is due to being in Emacs.

Emacs is not really an editor: it’s an easily user-extensible operating environment with a remarkably shallow learning curve (seriously: one can go years just setting variables before moving up to simple functions and then starting to explore). Having all that power so easily accessible is a part of what makes Org Mode great. It’s what means that each Org Mode user can mold his experience to his needs.

ants_everywhere•26m ago
I think it's kind of the other way around.

Emacs is a universal lisp environment, and org-mode is a lightweight markup language that works well with it.

You can port the markup language, but it's a heavy lift to port the lisp way of thinking to another language.

durazabu•18m ago
The reason is that elisp org-mode is huge and re-implementing it without elisp is a great undertaking.

I started an implementation in javascript that I integrated in an obsidian plugin [0]. But the plugin has a long way to go before reaching feature parity with emacs orgmode.

Org-Mode with Hyperbole it's like doing computing in 2070, but without bullshit AI LLM's. Try it and you'll understand.

https://www.youtube.com/watch?v=cFdgpb0TeQo

If you are a Lisp programmer, you can OFC use ob-lisp with it (and maybe there's ob-elisp to learn Elisp in a literate way).

This is like a Jupyter netbook, with steroids. Org Babel:

aquariusDue•1h ago
Hyperbole is the weirdest thing ever (in a good way), I can't exactly describe it to people either because it's a monolithic package that is made up of a number of packages (like the one for window control) but once you start using it and adopting it gradually you reach an epiphany. At that point the usefulness of Hyperbole is evident but until then nada, it seems more hassle than it's worth (though there are moments when it has bugs relating to other packages, like org, but those are quickly fixed by the maintainers in my experience).

Though a downside is that you end up curating a workflow that is so tailored to you that it seems weird from the outside, if it ever leaks, i.e. weird notation in git commit messages. That's due to sprinkling implicit and explicit "buttons" (pieces of text roughtly) throughout text (source code or otherwise).

silcoon•1h ago
I wish there's something like Obsidian with the same support for org-mode that Emacs has. A few pros:

- Organize notes in org-mode is much quicker - The best support for lists (and I do list most of the times) - Tags and properties - Perfect integration with agenda - Great TODOs support - Code blocks with highlights, execution and results

medstrom•1h ago
Logseq has buggy syncing and imposes some odd constraints on your files if you want to keep it easy to edit the same file from both Logseq and Emacs, but in principle, it's all there!

Not sure if it can execute code blocks tho.

ubermonkey•34m ago
After a few attempts over the years to move to emacs -- all them failures -- what finally got me to use it consistently was Org. The funny thing is I still don't use it for coding or other writing; emacs is on my computer as the org platform.

I am VERY interested in Obsidian, which seems like it could definitely support an org-like system. It's _almost_ there as far as my own use cases are concerned, and the seamless sync to mobile is really enticing.

But goddammit, my fingers now know how to move through org buffers pretty well, and Obsidian lags on that front, so I may be stuck. ;)
