Proton released its new AI called Lumo almost a year ago. Lately, I've been moving away from using Perplexity (PP) and ChatGPT because I'm pretty sure they're just psyops. Perplexity isn't a cheap subscription, so after getting my one-millionth free access code, which I've been getting consecutively since 2022, you just get kinda sus. I don't think PP devs have given me free access for almost 4 years out of the kindness of their hearts, and moreso because they just want to harvest my behavior patterns for their overlords. Hence why I've started using Lumo.
But anyway, if you'd like to use Lumo as your browser's default search engine when you search for something in your address bar, I've put the steps here on how to do that.
Brave or any Chrome-based browser
Open your browser > 3 lines in the top right > Settings > Search Engine > Manage search engines and site search. Under Site Search section, go to Add and enter:
Name: Lumo Shortcut: :lu URL with %s in place of query: https://lumo.proton.me/u/c/search/?q=%s
Select Save. It will be a new entry in the list. Next, click the 3 dots beside the Lumo entry you just made. Select Make Default.
Restart browser.
Now you'll have Lumo as your default search engine and even have the little purple Lumo cat head icon in your address bar, too.
Do a test search and it will automatically answer your query in Lumo.
Firefox
Firefox is setup the same way, but I haven't gotten it to fully work yet. It doesn't like the search url and the same search url that's used in Chrome-based browsers won't fork for Firefox. Go fig. But anyway:
Open Firefox > 3 lines in top right > Settings > Search. Scroll to the bottom. Click Add. Enter the following:
Search Engine Name: Lumo URL with %s in place of search term: https://lumo.proton.me/u/c/search/?q=%s Keyword (optional): :lu
Click Add Engine. Scroll to the top.
Under Default search engine, select Lumo.
Restart your browser.
And this is the part where it breaks. If you do a search, it tries to search, but then just goes back to the Lumo home page. Don't know why it does that, but I'll figure it out and update these steps.
Otherwise, if you're on Chrome-ish browser, you're welcome.
