Why is there still no simple way to just save and reuse our own AI prompts?

I’ve tried a bunch of tools — most are either too minimal to be useful, or so bloated that they try to be an “AI platform.”

Has anyone here found a lightweight, no-BS solution that just handles prompt management well?
(If not, maybe it’s time we build one together.)

Update with my finding AT 10/21/2025:

Seems that this one is close to what I am looking after, better to have more enhancements, https://chromewebstore.google.com/detail/lcagjfmogejkmmamjnbnokheegadijbg
