Altroo is a search engine that allows users to support charities simply by searching the internet. This Chrome extension replaces the new tab page with Altroo, making it convenient for users to contribute to charitable causes while browsing the web.

When users search the internet using Altroo, each search increases the next donation by a small amount. The donations are funded by the ads provided by Altroo's search partner. The best part is that Altroo is completely free for users to use, ensuring that anyone can contribute to charities without any cost.

Altroo emphasizes transparency by making reports of their donations publicly available, allowing users to see where their contributions are going. Additionally, Altroo's search is powered by Yahoo!, ensuring high-quality search results for users.
