Questions
Good to know.
Why does the first run take longer?
The tool downloads its AI model to your browser the first time. After that the browser keeps it, so later runs start faster.
Do these AI tools need an account?
No. There is no sign-up and no credit system.
Is my file sent to an AI service?
Most of these tools run the model inside your browser. Each tool page says what happens to your file, including the few that use an online service.
