We describe a crowdsourcing platform for writing called CreativeWall, where users can preserve their creative writings and share them with the community. By using images, moods and locations we create a more visual perspective of a moment that can bring creativity and mental well-being to the writer. We also present an evaluation of our crowdsourced platform. Our findings suggest that, from a mental well-being perspective, the participants felt more inspired, more focused, more creative and more immersed when using the CreativeWall add-in. Additionally, CreativeWall helps writers to trigger their creativity while writing. We highlight some results triangulating qualitative and quantitative data. Results show that users performing the tasks with CreativeWall lost track of time more often than participants using our baseline. From user interviews, results suggest that the tasks performed with the CreativeWall add-in were more enjoyable and that the users had no issues kickstarting the writing process, which could mean that these tools can help in the initial phase of the creative writing process.
