What ShareDuo has that HTMLRadar does not

Do ShareDuo and HTMLRadar readers need an account?
No. ShareDuo says anyone with the link can open it in any browser, without a Claude account. HTMLRadar readers also need no account and never pay.
Can I see who read a ShareDuo link?
ShareDuo’s homepage lists a view count and the time the link was last opened. HTMLRadar shows who read the page, which sections they read and the time spent on each.
Can I publish from Claude with ShareDuo and HTMLRadar?
Yes. Both publish from Claude and other assistants. In HTMLRadar you can then ask the assistant who read the link and which sections they spent time on.
