Most “best app” rankings rely on outdated ratings.
Apps change over time, but their old reviews stay forever. Popular AI extensions often keep high scores even when recent users are unhappy. Smaller or newer extensions with great feedback rarely get noticed.
This ranking focuses on the most recent 100 reviews, updated daily. It shows what works today and gives every app a fair chance to be discovered.

How this ranking works
Each app is ranked using the average rating of its most recent 100 user reviews. This approach reduces bias from outdated feedback and highlights current performance instead of long-term popularity.
Here is an overview of the best-rated AI extensions on Chrome based on the most recent 100 reviews:

Now, looking at the table above, we can see some interesting things we wouldn’t spot by just looking at the total reviews and ratings.
Across all reviews, Youtube Highlighter & AI Summary has the highest average rating: 5.0 ⭐ from 6 reviews.
But the “best overall” isn’t always the one users love today. In the most recent 100 reviews, the current #1 is Youtube Highlighter & AI Summary at 5.0 ⭐.
That’s the best-case scenario. The all-time leader is also the most loved right now, which usually means the app has stayed solid as it grew.
Quick takeaways:
- Best right now: Youtube Highlighter & AI Summary leads the last 100 reviews.
- Best overall: Youtube Highlighter & AI Summary has the highest all-time average.
- Most shaky recently: Grammarly: AI Writing and Grammar Checker has the lowest recent score (last 100 reviews) and sits at #13 overall.
A low recent rating doesn’t automatically mean “bad app”—but it’s a red flag we wouldn’t ignore, especially if the all-time position is much higher.
