I've used a gazillion project management and collaboration tools over the year. The first one was Teamwork, which I have fond memories of. This was over 10 years and more work was done over email and spreadsheets.
In the last two years my go-to tool has been Notion. It combines docs with Databases, so like working in Word and Excel at the same time. Kinda :)
It's superpower is not functionality. It's that you're crating and collecting knowledge in one place, that easy easy to access and manage by anyone. With Notion Dev Tools you can pull and push data in and out. In other words, AI has all the data / content / context it needs to do its work well. Powerful stuff.
