Thanks! Basically it was just an inconvenience I had whenever making product announcements/concepts for both Dribbble and Twitter, where I would record the screen of a product in action and then have to spend ages in After Effects to make it look nice with a prototype, render, and then usually have to get the video, compress it, and use a MP4 to GIF converter if I wanted to post in Twitter (GIFs seem to be more effective there).

With this tool I literally just upload the recording, quickly place it however I like, and I can export directly as GIF. No hassle :P
