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 next
happy to answer anything about the build heres the landing page https://cooldownman.netlify.app
