You want to see all your team’s smiling faces, right? That’s not always possible when working remotely, but online collaboration tool appear.in is the next best thing. This brilliant video conversation app allows up to eight people to converse in a chat room, with no login or downloads required. And it’s totally free to use.

Mural is a creative tool for you to drag-and-drop rich media files, links and documents onto a big HTML5 drawing board, which is a great way to collect inspiration and gather your thoughts. It also supports collaboration that allows designers to brainstorm cool ideas remotely. Plus, it is optimised for iPad and made gesture-friendly.
Mural is not just designed as a pinboard like Pinterest – its main goal is gathering and organising ideas. Anyone can join you to edit and collaborate, and changes are reflected on the board in real time. Just send an email invitation or set up a password for the board and you are ready to go.
Tools like this are lighter than some of the more traditional brainstorming tools, and if you’re new to collaborative brainstorming then this could be a good place to get started.

Free tool GoVisually allows you to mark annotations and place comments on any part of your project. With it, designers and clients can collaborate to revise projects online without sending painful emails, which should ultimately increase productivity.
For your annotation you can chose an elliptical, rectangular or lasso selection, as well as customising its colour and weight. These functions are very useful, and are as simple to apply as you’d find in a basic drawing app.
When multiple team members are on the same page, GoVisually applies layers for each user, like in Photoshop. Clicking on each user hides or displays relevant content, which is particularly useful when collaborating with different departments. Revisions can be easily upload and it is simple to switch between different versions of the same document or project.

Scribblar is similar to a chat room – it even has audio available – and as such it is very useful indeed. Creative brainstorming and artwork revision can be collaborated in the ‘room’ you create. It’s an effective online collaboration tool and is available for free.

Ideaflip makes it easy for your team to quickly turn thoughts into ideas, and share or refine them – whether your collaborator is in the same room or on the other side of the world. A beautifully simple web app, Ideaflip is perfect for group brainstorming and individual ideas. A great way to compose, collect and clarify your ideas.
