Questions about OumaShu
What is OumaShu?
OumaShu (櫻滿集) is a free directory of 35 online tools, grouped into 12 lines like a train map: image, video, audio, text, learning, games and more. Each tool opens straight in the browser, with nothing to install and no account to create.
Are the tools free? Do I need an account?
Yes, every tool listed is free to use and none needs an OumaShu account. OumaShu itself is paid for by Google AdSense ads. A few third-party sites may offer optional accounts or paid extras of their own.
Are my files uploaded?
Most image, text and audio tools built for OumaShu process files locally in your browser, so the files never leave your device. Tools that need a server by nature, such as AI conversation practice or the temporary chat room, send data to their own servers. Third-party sites follow their own privacy policies.
Who makes OumaShu?
OumaShu is built and maintained by Rollkey, an independent developer (@Rollkey4 on X). 29 of the 35 tools are Rollkey’s own projects; the other 6 are third-party sites, marked “3rd Party”.
How are tools chosen, and how current is the list?
A tool is listed only if it is free, works in a web browser and needs no sign-up to try. Each entry is checked when it is added or changed. The list was last updated on October 12, 2026.
