Experience the best out of a video.

Shimasu helps you get the best out of a video by providing real-time information and insights on the video you are watching. On any video that a user watches with the intent to learn, they can enable Shimasu to help them learn faster and more efficiently. Shimasu offers reliable suggestions ranging from pictures to word meanings. Shimasu uses its powerful AI to detect which words or concepts the user might find difficult and then display the related information beside the video.

Video, huh?

Our Mission

We envision ourselves as a free platform for education with powerful AI that makes us different from all other platforms. We wish to make this world a better place by providing the best free platform for education where millions of users can learn through videos on any topic. For our vision even one piece can help us change this world and make education accessible and affordable for everyone.

How does it work?

Let's say a user wants to learn Javascript or play a guitar.

Opening Video

The user opens a YouTube video on a certain subject and then encounters certain words or concepts that they are not acquainted with.

Using Chrome Extension

If the user has pre-installed and activated the Shimasu Chrome extension, the definitions and suggestions that the Shimasu AI generates based on the subtitles of the video appear right next to the video.

Enhancing Learning Process

The user learns subjects in a more efficient and better way from the suggestions received which enhances their perception and understanding of that particular topic.

These are some frequently asked questions. If you have a question that is not answered here, please feel free to contact us.

Shimasu is not an application. It uses Chrome to store suggestions in the local storage. However, it doesn't do that by default, so you will have to change the settings in Shimasu Settings.

We hate ads as much as you do. There are not and will never be any ads within Shimasu itself, but we cannot guarantee that for the video you are watching. Please note that if you see any ads, remember that we're not making any money off of them. :)

Absolutely not. We do, however, offer our Pro Plan, which isn't necessary, but it's affordable and worth the cost. Check it out in Plans.

We offer a one week free trial of the Pro Plan.
