No account. No quota. No upload. Everything runs in your own browser, because for these four jobs there is no reason it should not.
Screen recording with no watermark and no time limit. Records MP4 directly.
Fills the forms you fill often. Unlimited, local, and it never touches passwords.
Saves any page as a PDF, including pages you are signed in to.
