Articulate, a company that is best known for developing e-learning software, has just launched ScreenR (short for Screen + Recorder). It’s a free web based screencasting tool that lets you create digital recordings of your computer screen from any web browser without requiring software [*].

With ScreenR, you can record desktop movies of up to 5 minutes and, if you have a microphone, you can also add voice narration to your screencasts. Once the video is recorded, you can upload it to YouTube (as 720p HD) or save it locally for further editing in the popular MP4 format.
