Yes, I think you're right. An explanatory sentence would be nice. In the FAQ it says

"Mailvelope is a browser extension (in Firefox it is called an "Add-On", in Chrome an "Extension") and it expands the functionality of your web-browser. Mailvelope offers email encryption with PGP for the Firefox and Chrome browsers."

which is quite different from what I'd expected!

Yeah maybe it should be more obvious but Mailvelope just adds end to end encryption to existing webmails (through extension overlay).

I really hate how product pages are made these days. You get four callouts - "Revolutionary Engagement!", "Insight at the Speed of Business!", "Continuous Introspection!", "Value Sharing Ethos!", with no explanation of what the damn thing is actually supposed to do.

The "Documentation" section actually shows you what it does (better than the FAQ explanation some have mentioned)

https://www.mailvelope.com/en/help

It's free for personal use, but there's also some paid tiers. As far I can tell it looks like the only thing Mailvelope does that is outside of the extension/your-local-machine is host their own key server: https://www.mailvelope.com/en/faq#key_server

Unless there's something also it does that I'm missing?

FYI, it's open source: https://github.com/mailvelope/mailvelope

This is such common thing nowadays, I'm not even sure how we got here. About 50% of the products (including open source projects) people pitch here have websites like this. I literally give up if I have to click more than twice to understand what a product is.

Seems like a browser extension for PGP encryption.

Seems pretty clear to me
