You're probably just learning about Slite after having heard of the all-in-one tools like Notion and Coda (amongst the many other team "knowledge base" apps on the market), and wondering which is right for you.
If you're truly looking for the knowledge base "category defining" app—there's no one better than Slite. They are actually moving this category forward in what it traditionally has meant to be a shared team knowledge base/documentation tool.
What we actually love most about Slite is their simplicity and focus. They have the cleanest UI/UX of all the tools we've tried in the space. And while you can still modify the design, your team will never get lost in the formatting, nor can you actually make a document look bad in Slite (unlike competitors).
It's pretty heavily focused on being your team's shared knowledge-base and asynchronous collaboration tool. Think: finding information across your shared team's brain, making decisions, and being able to easily reference how and why decisions were made with Slite Discussions:
Example of referencing a Discussion (decision made) within the relevant documentation
Think of a Discussion as a reference-able email thread with key stakeholders that ultimately has a decision. Imagine new team members could not only see what your internal processes are, but even how the decision was ultimately made to get there? Yeah, that stuff currently gets lost in old Slack and email threads. What if it it didn't have to be that way?
Working on large internal projects? Notes are in Slite. Brainstorming marketing ideas? That's in Slite too. Important discussions being had? Move those from Slack to Slite. You can even invite external stakeholders (e.g. customers/contractors), and they can easily collaborate with your team without much of any friction.
