Well I have been craving a simple tool like this for a while and now that you guys have created it and in such a simple way to use I really like this. Just removing these simple em dashes make text feel more human. Thank you
I really like this kind of single-purpose plugin because it's simple enough and usable enough
For me, this solves an issue I didn’t even know had a solution. I always thought I’d have to manually clean up AI-generated text forever. This plugin proves otherwise. I’m really impressed by how seamless it feels.
Haha, I never thought we'll need a tool like this but this is super cool now haha
I did not know that people are annoyed by them. But it sounds like a new action idea for RewriteBar. :)
Haha, great idea to come up with this! Skipping em dashes cannot be missed in all of my prompts :)
Love this idea! It's a great way to make AI-generated text feel more natural. Does Undash work on all websites, or are there specific platforms it has trouble with?
Product suggestion: In the next version, include GPT-words replacement. That would be even more impressive.
If the extension isn't working as expected, it will be mostly because it is not loaded correctly or in time for it to handle your clipboard.
Try the below steps:
1. Toggle the extension OFF and ON
2. Check that the badge is green (active)
3. Refresh the browser tab
4. Restart Chrome if needed
5. After paste, click space or try right click and undash the text
6. Make sure at the time of copying the plugin is enabled
i really wanted this to work, but unfortunately it's not working. I'm on windows fyi.
Such a neat little fix! Undash solves a real annoyance with AI text formatting — clean pastes without extra effort. Love the plug-and-play approach. Simple, smart, and saves time every day.
