Asks for payment right away

Genuinely a life changer, I don't see myself using YouTube without it, and there's a surprisingly great amount of community-generated titles and thumbnails available.

Tried it for a couple of days and ended up buying it. It's a bit slow when loading the thumbnails, when opening my subscriptions it takes about 6 seconds for everything to load. But it's worth it, I love it, it removes the sensationalism.

Let's get this out of the way, this doesn't remove clickbait. There's too many channels posting garbage by the second for new titles to be submitted and the De-Arrow user count is a fraction of SponsorBlock's.
What this actually does is remove sensationalism from channels that people watch regularly. Sometimes to an asinine degree. (ha i know big word)
"The city with a hundred private cable cars" is a video from Tom Scott. A De-Arrow user changed this to "Wellington has over one hundred private cable cars". For some reason I guess "this city" was deemed too sensational or vague, so adding the city name and a slight rewording makes it less so?
Another Tom Scott example, "Things are changing at the world's oldest hotel" becomes "Modernization of a Japanese hotel that is technically the world's oldest operating business". Okay, an example of a title that's actually de-sensationalized by a user, but now it's longer than needed and over-descriptive. Many titles are like this, if the De-Arrow community made a restaurant menu, common delicacies would include "Not actually French potato fries" and "Ground beef patty sandwiches with vegetables, condiments, and cheese in soggy buns".
De-Arrow has a voting system where you can dislike or like submitted elements and submit your own, but the Tom Scott examples above are submitted and locked by VIPs.
What's a VIP? Well, someone with insider access who can submit titles/thumbnails and no amount of dislikes or voting can displace their locked submissions. Currently, there's no way to apply for VIP status, it's strictly for the coolest of dudes. I'd be fine with VIPs getting an voting boost based on their status, but not being able to vote on these titles is stupid. This isn't SponsorBlock, where a Sponsor segment can be objectively correct based on start/end time, someone may be able to summarize the info into something better, like "Modernization of the oldest operating hotel".
Filler tangent/jokes aside, I'd still recommend De-Arrow to display auto-generated or user-submitted thumbnails, I don't have much to complain about there other than thumbnails sometimes not loading when enabled. For title replacement, you can use the "channel allowlist" so selected channels use custom blocking settings, although some visual issues occur on YouTube when both whitelisting and blacklisting, keep that in mind.

Not a terrible idea but the culture is awful, titles are often VERY unnecessarily edited and actually take away from the youtube experience.

Great Add-on. Thank you so much.

Fantastic, completely non-intrusive. It's nice actually knowing what certain videos are going to be about before clicking them.

Worth the dollar. When videos are missing submissions I feel compelled to add one.

This makes YouTube bearable. I miss it when I'm on mobile.

This add-on makes Youtube seem so dull.
And that's a good thing.
Only issues I can see is that I keep checking the original titles out of curiosity (which is my own fault) and that the page lagged severely when I tested it on Mr. Beast's channel (which was rather amusing).

Immediately my YouTube homepage became much easier to the eye, I'm also way less prone to click on stuff I really wouldn't have clicked otherwise (which I bet is exactly the purpose of this).

I like it so much more, in a sense the thumbnails become a little insipid, which is something one has to unlearn, but overall this extension brings unfathomed peace.

I think that acronyms should remain unchanged, since its easier to comprehend what's the title all about; also looks better, specially on team names and such.

Thank you very much. I'm an unpaid user, so thank you again and will send my grain of sand once I'm able to.

Thanks again. As an avid YouTube user, I really recommend this extension.

Check other extensions such as SponsorBlock, Enchancer for YouTube, Return YouTube Dislike and YouTube Short Block, all of which I use.

Legendary!

easy to use, good for me
