Thousands of runnable AI demos, no model installed on your machine.
A hosting layer for small AI apps, which in practice makes it the best place on the web to try a model before committing to it — background removers, speech recognition, OCR, image generators, all as working pages. You can browse by task, and most Spaces run without an account. Free Spaces sleep after inactivity and take a minute to wake, and a popular one puts you in a queue behind everyone else who read the same post.
Questions
Works the moment the page loads. No account, no email, no trial. Free Spaces sleep when idle and queue under load, so a popular demo can take minutes to respond.
Yes. Hugging Face Spaces sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
