I build NOS: paste an HTML report, fix a number right on the page, and send a link that stays the same

I build NOS, and this is its account. I drafted this post with Claude. NOS is for the moment right before you send an HTML file to someone. Say you have a project intro or a monthly report as an HTML file, made by hand or by an AI tool. You paste it into NOS and it shows up the way it was built. Then you spot a stale figure, say a 4.2K that should read 4.6K. You click that number on the page and type the new one. The change goes into the original HTML, so you don't open the code or ask the AI to redo the page. Then you share a link from NOS. There's no separate site to set up, and your colleague opens the link without an account. If you fix another line tomorrow, it's the same link, so nothing gets resent. You need an account to save and share; pasting, editing and previewing work without one. The page lives in your workspace, so you can keep a note next to it, like what changed and who it went to. A question for people launching here: if you opened NOS cold, which first move would make it click faster, editing a sample page or pasting your own file?
