All Apps List - A Wiki of tools in the PKM and productivity space

This is a regularly updated list of applications, tools, and services in the Personal Knowledge Management and Productivity space. It is intended to be comprehensive if not exhaustive. Note that our focus here is primarily on tools for personal or small team use, we are not intending to list a majority of enterprise-level options.

Tools are organized by type, with brief descriptions and links to more information (generally the official website). Applications are listed in no particular order (for now) and formatting is a work-in-progress. Reviews or other 3rd party resources are provided where possible. When an app fits into multiple categories it will be listed in all, with reference back to a primary one for the bulk of the information.

This post is open for editing once you reach a certain level in the forums here, which you can attain simply by interacting - posting topics and replies, etc. Feel free to suggest new apps or other edits in the replies below until you’re able to edit directly!

Airtable Database for a Master Task List :

  • We really appreciate the efforts of @lordrudraksh, for sharing with us his airtable database, that already contains a pre-seeded list of apps that we are trying to cover here.
  • This might be a better way to keep track, due to it’s filter and tagging features. I hope everyone find’s it useful
  • Kindly contribute to the list by posting about any app that you think should make it into the list.

Additionally you can reference these extensive lists:

And this great site focused on note-taking apps in particular, which includes search-by-feature tools, startup time tests, and more:


Help you ! Notion – The all-in-one workspace for your notes, tasks, wikis, and databases.


Thanks for the link. I had already bookmarked it, but I’m not sure I’ve read it yet.


How can you use Obsidian as an outliner?

(btw I am searching an outliner with local data storage)

Well it behaves like an outliner if you need it to .
Indents , collapses etc

But I agree , it should rather be under PKM . Its not a traditional outliner .
@Oshyan your thoughts ?

I sense a problem with listing these tools here , some of the tools can’t be defined as specifically under PKM / outliner / not taking . They often overlap and also occupy the grey areas . We need a table where we can have multi-select options . Something like notion or walling might be a good way to do this . Notion might be best I think .

Yeah, I definitely have it bookmarked and it’s a great resource! Thanks. :slight_smile:

What is the differences between “behaves like an outliner” and “is an outliner”? Is Obsidian too broadly functional to be an outliner?

Perhaps. But it’s very often spoken of in the same context as Roam, which is an outliner (and, well, more, but also still an outliner). We’re getting into definition of terms to some degree…

I did already address that tools may exist in multiple areas:

That is undoubtedly the ideal, however it makes it harder to edit collaboratively (potentially). And is also a bigger project. Here we have something simple, collaboratively editable, and which can be evolved over time. It can be “good enough” as a basic list, though it is certainly not the best possible reference, and I wouldn’t really intend it to be.

That said, if people generally feel it’s not a useful enough approach to the problem, we can do something else. I don’t have time/energy to set it up in a different way, hence this Wiki-driven discussion thread. But I’d welcome anyone else’s efforts for sure!


I’ve already request this feature. I’ll push it after v1.0.0

2 Likes have advanced table features than Notion’s.

Yes , it is . It’s a blend between traditional word processor styled writing and can go outline if you want it . But it doesn’t lock you in with that . That’s kind of what I like about it the most !

Interesting , what category would that fall under ?

I agree, Obsidian is too far removed from that kind of functionality to be an outliner, though you could create multiple outlines in it.

My go-to outliner has always been Workflowy. Boi oh Boi is that one hell of a system. It’s an Olympic-level bullet-point athlete.

Also, Coda was pleasant to use when it first launched, I can only imagine it’s powerfull as hell now. That being said, I absolutely can’t afford it when I can use python, csv, sheets, and excel to replace AirTable, which is more powerful, but far less portable (compared to Coda).

If I could get the full versions of Coda or Airtable for free I’d probably never leave my computer. This especially goes for Airtable.


Excellent, then there is consensus! (at least on Obsidian) And the solution is clear: someone should edit it. It’s a wiki, go for it! :grin:

I’ll do it … as soon as I work out how … :slight_smile:

There’s an edit link at the bottom of the first post in this chain. Does that help?


Sadly I don’t think it’s visible to me. From what I can tell, I’m not a full member of the forum, only a basic one. I might not have access to that functionality.

Hah! You’re totally right, somehow we hadn’t given you proper permissions yet. Sorry about that! You should have access now. :slight_smile:

Heh, I thought it was something tied to how many times I’d posted. Grazie ragazzi!

I’ve added a few more details based on apps that I’ve used. I’ll add more once I get the chance.

whatever. But 's focus is not on note taking software


Coda’s more of a collaboration tool. It takes a lot of features from software like Airtable and Sheets, gives it a strong presentation layer, then puts a lot of focus on collaboration and sharing. Steve is right, it would be my last choice for note-taking, but for showing your results to a colleague from another department or a client, it’s probably the best thing short of Jupyter or Collab. When I last used it, it was certainly ‘best of the rest’, it just costs a lot.
