We developed a web-based molecule visualization tool to enhance molecular sanitization through visual inspection. Organized visualization of the chemical space of molecules is necessary to check the computer-generated molecules. In addition, we encourage users to share their molecule lists with the world and vote for promising molecules to gain the wisdom of crowds or collective human intelligence . The web service is available at . Although the main goal of this project is to share molecules for collective knowledge, users can build their own server using the source code for the service if they want to deal with private data.
