You're probably looking at Slite after having at-least hearing of the likes of Notion and Coda (amongst many other team "documentation" tools).

What we actually love about Slite is their simplicity—they have the cleanest UI/UX of all the tools we've tried in the space. You can still modify the design, but you will never get lost in the formatting—you really can't make a document look bad in Slite (unlike competitors).

Slite is pretty heavily focused on being your team's shared knowledge-base and asynchronous collaboration tool. Working on large internal projects? Notes are in Slite. Brainstorming marketing ideas? That's in Slite too. You can even invite external stakeholders (e.g. customers/contractors), and they can easily collaborate with your team without much of any friction.

Notion and Coda have developed over the years more and more into database tools (similar to the likes of Airtable), evolving outside of the documentation side of things. Some people love these tools for that reason—we do not. People report Notion and Coda becoming too complex and slow to load in time. The question becomes more of "should we use Notion for this"? Because while it can be used for many things, rarely is it the actual right tool for the job. As they are trying to be all things to all people, it results in them being "not great" at most things.

A team using Slite on the other-hand know exactly when they should and shouldn't use Slite. While the use-case can extend out a bit more than just team documentation (e.g. we even use Slite for quick proposals—as it's a super quick to template and to throw thoughts together—before sending them off to a potential customer). Although it becomes quite apparent when you should instead use a more structured Proposal / eSignature tool like PandaDoc—which is a good thing.

The only downside is Slite does not currently have an API (so you can't build custom integrations with it)—while we'd love to have these capabilities, they aren't all that important for the way we recommend teams use Slite.
