Sean Forde found Boomwriter:

• Moderately improves teaching efficiency and productivity“Over the years the Boomwriter platform has evolved greatly. The things you are now able to observe, complete, and interact with your students writing make the whole writing process and projects flow even better.”
• Significantly reduces teacher workload“As the platform is all the web, it allows all of your student work to be collected in one spot. The engagement of your students grows and develops the more the students use and interact with Boomwriter and thus helping build their quality of writing and the amount of work and editing that might have be through other writing styles.”
