@nirmalnd I have been manually fixing em dashes for months, particularly when I copy and paste AI-generated drafts into Google Docs. Ahhh, this really seems like one of those “why wasn't this available sooner?” tools :)

Does it also detect odd curly quotes or extra spaces while it's at it?

@hamza_afzal_butt

Hi Hamza, thanks for trying out the extension. :)

If you can share some examples on hola@outdoinc.com, I will try to add support for these in the upcoming versions.

i really wanted this to work, but unfortunately it's not working. I'm on windows fyi.

EDIT: not working on some apps, working on most 👍🏻

@yuvraj_dagur

Hi Yuvraj, Thanks for trying it out. This is a vibe coded app created on cursor during my off time, but I am happy to improve this for users who would love to make this as part of their daily use (like me and my team).

I have personally tested this on LinkedIn, Gmail, Twitter, Linkedin, Facebook, and few more places and v1.1 is already uploaded (awaiting for Google to release it).

There might be some troubleshooting required, try this

If the extension isn't working as expected:

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

If you are still facing the issue, can please share some screenshots/video recording to understand the issue better, so I can get look at fixing those. Please send it on hola@outdoinc.com

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.

@supa_l Thank you :)

Launching v1.1 (awaiting for google to approve) with improvements to handle iFrames.
