I'm building NOS. It's for people who make HTML reports or proposals, often with AI, and then need to send them to someone.
Say you paste an HTML report into NOS and then notice the title still has last quarter's date. You click the title on the page and retype it. You don't open the code, and the change goes into the original HTML.
When the report is ready, you sign in and create a link. The people you send it to can open it without an account. If you edit the report again later, the link you already sent shows the new words. You don't have to send a new link.
You can paste, edit and preview your own HTML without an account at https://nos-workspace.com/. NOS is available now, and the free plan is $0 with 3 share links. The screenshot is the built-in portfolio demo from that page, with Korean sample text.
When you click a heading in the demo and retype it, what do you expect to happen to the original HTML?
