Quip

The search is pretty key vs other competitors I've used. Comment threads, and interlinking between docs is great. Embedding images/filetypes + having long documents not consume a ton of resources on my machine needs a bit of work though.

Anything that competes with Google is a real plus in my book. ;-)

It is a fantastic document collaboration tool. I started using it 3 months of its launch and have been using it ever since. It is a perfect tool for teams to work together and have real-time feedback and collab.

Useful, easy to use, note taking app that I can use across apple and android devices.

Don't have to deal with formatting decision fatigue

It has real spreadsheets when compared to similar note-taking or team wiki software

The best cloud-based document app with a clean, easy to use UI and lots of helpful widgets and integrations.

Simpler Google docs. Gives up some of the power features in exchange for something easier to use. Sensible formatting defaults so everything looks good.

It's my IDE

We use Quip at Product Hunt to manage most of our documents and briefs.
