3 weeks ago i almost sent a passive-aggressive ok cool to my CTO at 11pm. caught myself in time. realized this happens to me like weekly so i built a thing for it.it s called cooldown. when you hit post/send/tweet, a small modal pops up with a countdown (10s by default). you can cancel or send anyway. that s it.the part i actually like about it: it doesn t trigger on every message. that would be insanely annoying. it only kicks in when the message is: - long - in all caps - has a trigger word you defined (mine are really , hate , quit ) - or just at night (auto night mode between 10pm-5am)short stuff like ok or lol passes through silently. you forget the extension exists 90% of the time.works on twitter/x and reddit. nothing else for now. linkedin was on my list but their composer is in an iframe and it was a pain so i dropped it.100% local, no backend, no account. ~30kb total.couple of things i d love feedback on: 1. does the smart mode thing make sense to you or would you actually want a delay on every message? 2. besides reddit and twitter where do you regret-send the most? trying to figure what to add nexthappy to answer anything about the build heres the landing page https://cooldownman.netlify.app
