Show HN: A Gmail extension that stops you from sending emails you'll regret
chromewebstore.google.comHi HN,
I built a tiny Gmail extension that adds a quick safety check before emails are sent.
It catches common mistakes like: - mentioning an attachment but forgetting to attach it - sending emails late at night - messages that sound more heated than intended
There’s no AI rewriting or analytics — it just pauses the send when something looks off and lets you decide.
This started as a personal itch after sending one too many “oops” emails. Would love feedback from people who live in Gmail all day.

Is the source available anywhere? <no-longer-relevant>Given that it captures messages and processes them somehow, having visibility into the business logic involved would help create trust (especially so since "messages that sound more heated than intended" implies that message content is being sent out to a third-party LLM).</no-longer-relevant> EDIT: I ended up pulling the source from wherever the browser extensions live out of curiosity, I take that part about third-parties back. Given how many of these extensions feel like data grabs, I'd suggest leaning more on the "this doesn't make any network requests to anything" angle. It's a huge plus when handling sensitive data. Now, saying it doesn't quite replace posting the source upfront so users can audit it themselves, but it's a great step in the right direction. > mentioning an attachment but forgetting to attach it Gmail already has this, it'll say "It seems like you forgot to attach a file." yes, that is true.
this project will extend that to outlook and more email clients. Also, I am putting this minimum version out to test if anyone finds it useful.
