Quip

I love seeing how organized and most importantly easy to maintain all the docs in the company and departments. I think this is what makes Quip different: it's often easy to start using some service that meets the same purpose but it becomes a mess in a few months. Absolutely happy how it worked for our company with Quip. It was also a big help to find everything I needed when I joined the company.

I would love Spreadsheets which you can create in Quip to have more functionality, sometimes I need to use other tools and just link to them since I can't achieve the same with the Spreadsheets in Quip.

Quip is very easy to use and navigate within the software. Basically, it offers you a never-ending list for your notes (very similar to OneNote for example). You can style these notes with basic formatting similar to MS Word: underline and strikethrough words, make them bold, or change them into italics. You can also choose the size of the words but this is a bit limited.
The best thing about Quip is the collaboration in real-time so you and all your coworkers can be always on the same page and they can edit the list by themselves at the same time.
Another nice feature of this tool is that you can mention people in the document and assign them to some action.
Also, you can set up reminders for the actions and you will receive a reminder on your email (usually one day beforehand).
Besides writing pure text, you can create sheets similar to MS Excel and formate the cells as needed. You can also insert a calendar, a todo-list, and other features.

The text you are writing is always centered way too much on the page meaning there will be a lot of unused space around your text.

It's very easy to collaborate on a document. You just add people to it. All the changes are logged so you can see all the things that happen to your document. You can also create all kinds of documents on Quip, from the everyday text document and spreadsheet to the specific kanban board and project tracker (with a little help from Live apps).

The app lacks the ability to add tags - which will be very helpful to further organize the documents. It also doesn't hurt to add the font-customization feature so that users can set the look and feel of the working environment to their liking.

We really like Quip the way it is built as the platform itself acts as a source to maintiain all the tools like docs, chat etc. in this single app itself. Quip is the best way to manage all the different tabs under one window. The major hike is with the single window system where all the needed plugins are added and can be managed. Quip is the one and only platform to simplify the user burden of maintaining multiple apps and multiple windows.

The UI is very hard to understand at the first time and for newcomers.
