Since seeing Den's #1-of-the-week launch, I've been playing around with it. I'm not quite at the conviction yet to rip out Slack and Notion. That would take a lot, especially given how much history and data we have, as well as workflow practices around it. But I'm finding it really intriguing so far. Here are my initial thoughts:

1) The merging of Slack channels and Notion spaces feels very natural.
Chance AI: Curiosity Lens
As a knowledge worker juggling multiple projects and information sources, Den has become my digital command center. Been testing it since launch, and it's like having a smart assistant that actually understands context. The fact that Y Combinator uses it speaks volumes about its capabilities.
The "cursor for knowledge workers" description clicked for me yesterday when I was researching a complex market analysis. Instead of jumping between dozens of tabs and documents, Den helped me navigate through information like a cursor through code - precise, contextual, and intelligent. Found insights in minutes that would have taken hours to piece together manually.
What really sets it apart is how it learns your work patterns. This morning, it anticipated the resources I needed for a strategy meeting based on my calendar event and previous similar meetings. The AI doesn't just find information - it understands how you use it and adapts accordingly.

@xi_z Thanks so much for this really lovely comment Xi! We have loved having you as an early user of Den!
Den
@xi_z Wow, seems like you really tried all the Den features. Thanks for your support Xi :)
@xi_z No but I desperately needed this in my life. I consider myself organized, but until now that meant tons of slack channels, canvases, different places to store information. Sure it was tidy but that was so impractical for daily use, I'm so hyped that there's something that does all this now! Hard agree that YC using is is a huge win, incredibly impressive.
this makes the canvas in slack feel so archaic
Den
@danielterrero thanks so much Daniel! We are hoping to make our documents that most simple and most aesthetic that anyone can use.
Den
@danielterrero Archaic is definitely the right word - I've been trying to put my finger on why, do you have any ideas?
@danielterrero No literally, that's exactly the right word?? Den just hits different lmao
Mixmax
As a solo founder, I am psyched about being able to hang out with all my agents in the same place where I try to manage my notifications. Excited to see where Den goes!
Den
@nworbrecneps We do it for the solo founders! When you say "manage your notifications", what do you mean?
Den
@nworbrecneps thanks so much Spencer! Den is actually most heavily used by solo founders, so you would be in great company!
Just from chatting with the team and diving into the features and content, I’m so hyped. Den isn’t just a new platform, it feels like a whole new way to work. You can feel the care that went into it, and it actually seems so fun to use. Now I just need to convince my team and uni courses lol. Game changer fr.
Den
@henrietta_vanniekerk let us know how we can help you convince them! Can't wait for you to test the new features we have dropping in a few weeks 👀
@linus_talacko1 Help me explain it to my dad/mentor who turns 50 soon? 😭
I'm sure I'll eventually figure out some way to show it though lol
Den
@henrietta_vanniekerk let me try:
Think of Den as your dad’s very own personal assistant that never clocks out—like Slack, Notion, and a team of interns all rolled into one (minus the coffee runs). He’ll wonder how he ever survived half a century without it!

@henrietta_vanniekerk
> Den isn’t just a new platform, it feels like a whole new way to work.
Um, can we quote this please
@justin_lee27 Do I get to be cited lmaooo? But yeah sure if you guys wanted to idm at all

I love that you want to bring AI to as many people on earth as possible with the goal of helping them instead of replacing them.
Den
@marco_dewey thanks Marco! We think that augmenting the work that humans are doing, rather than replacing it is the best way for AI agents to collaborate with humans.
Den
@marco_dewey an ambitious but worthy goal. Thanks Marco :)
Cua
This product is great - congrats guys. once you guys add also computer-use in the mix, it will become a must-have for every company/employee!
Den
@pupposandro Could we chat about this? The final unlock for so many of the agents is computer-use, and we'd love to use Cua :)
Den
@pupposandro thanks so much Alessandro! We can't wait to incorporate some sort of computer-use into Den, and would be really keen to make Cua our default solution ;)

Over the years Slack has gotten bloated with more and more half-baked features. Good to see a clean, sleek alternative with a powerful new AI-first paradigm!
Den
@mdebernardi1 we couldn't agree more! Thanks for the support Marcello :)
Den
@mdebernardi1 Sad but true! We're just trying to rebuild from first principles.
