Slite

The ease of use.
The search feature is very good and intuitive
You can create rich documents

Sometimes is very heavy consuming computer resources
Less integrations than competitors (for example there is not a gif integration, you can't connect other apps like a BPMN tool)

It does what most note-taking/knowledge management tools do. It can handle real-time collaboration as well as asynchronous discussion. I really make good use of the sharing feature, particularly for sharing a document publicly via a secret link for editing. This makes a zero-barrier way for other users to contribute, especially in one-off documents. In this way, users don't need to register for Slite to be able to edit a document you share (if you want to). This frictionless sharing has been so convenient. The Slite team is an agile team and I have interacted with them on numerous occasions to provide feedback and request new features, many of which they have quickly addressed. This kind of back-and-forth between myself and the team is a huge reason why I enjoy their product.Lastly, the cost is very reasonable. They have a very generous discount for non-profits and academics.

There are indeed some features that I'm hoping would eventually make it into Slite. So it's not perfect, but their dev team has been listening. I also have some performance issues with very long documents which I believe are being worked on.

I'm so upset with this company that I simply have nothing good to say about it other than it has a great UI/UX

I hate the fact that I have been billed for 8 months for a software I stopped using the first day. I deleted my account and they still bill me. There is no way to disable billing because the account does not exist and they do not respond to emails. Stay away from Slite.

It covers all the basics needed to make a knowledge base for a company but also includes amazing features like public pages or an AI helper and searcher integrated in the app.

The url names of the public pages could be proper words instead of random IDs.

Just so easy and intuitive and good value. Key features are not restricted from basic version and support is exceptional.

Copy and paste into other applications is not easy, as it loses some formatting . But I think this is common across other similar tools . I also wanted tasks to be built in, but this is not ready yet.
