Is there any support for popups or tooltips from AnnotatedString, or from text in general? For Desktop, specifically, but it seems like it would be a general compose API and thus more appropriate here. I looked into rolling my own, but the closest thing I could find is SelectionHandle & related things, but most of it relies on private stuff.

Sounds like you're saying there are some APIs that are unnecessarily taking in String instead of AnnotatedString or Composable Lambda, right? Can you be a little more specific by specifying exactly which composable functions (full signature) you're looking at?

Not really, or at least not as far as I'm aware of. I'm trying to show a popup when a user hovers over or clicks on a region of (annotated) text, like a link showing it's address on hover. Afaik there's no way to do that even if the popup I want is a pure string. I can use ClickableText to handle the clicks just fine, but there's no way to translate the character offset into a positional offset for the popup.

SelectionHandle and friends look like they do something similar to what I want, but only for selection. I looked at copying and modifying them, but they use enough private/internal APIs that doesn't seem possible.

Ah, got it. Yeah, I don't think there is any built-in tooltip support yet, but you should be able to implement such a thing in user land, and feel free to contribute it to upstream or publish it for others to use.

To display some content above other content, I would look into:
androidx.compose.ui.window.Popup(...)

And to measure the text so you can know how/where to position the popup, take a look at this thread:
