User reviews
Pros
- Casper AI provides concise and effective paraphrasing and summarization, helping users grasp key ideas quickly.
- The extension is easy to use and significantly saves time and mental effort for reading and learning.
- Users find Casper AI useful for improving the way they consume and understand online content.
- Multiple users appreciate the quality of AI-generated content, calling it fantastic and revolutionary.
- Many users recommend Casper AI as an essential and brilliant tool for more effective reading.
Cons
- The advertised ‘Free Tier’ is misleading, offering only 5 prompts that do not replenish, which severely limits users' ability to try features before subscription.
- There are frequent technical issues such as 'Error 400: redirect_uri_mismatch' when signing in with Google accounts.
- Several users report that the extension struggles with understanding context and provides irrelevant or limited responses, especially for complex tasks.
- Some advanced features like Video and Image generation are often unavailable without upgrading to Pro, which frustrates users.
- The pricing model is seen as aggressive and inflexible, forcing users to subscribe to the entire bundle rather than selecting specific AI tools.

Why does it show 'Error 400: redirect_uri_mismatch' when I sign in using my Google account?

I'd rate it at a HALF STAR or ZERO OF FIVE STARS if possible, it is totally false advertising!! It advertises a "Free tier". Ridiculously and incredibly ERRONEOUSLY INACCURATE! I'd say it could be 'possibly considered' a VERY LIMITED 'Free Trial" if anything, I downloaded Casper AI #CASPERAI @CasperAI over a week ago!! My inventory is still at "0/5 Free Uses Available"... I also see no literature that describes this as what they're offering, only the aseratation that there's a "Free Tier" in which you can use Casper AI in limited capacity. You can actually use Casper AI to FULL CAPACITY for just 5 prompts... This may or may not be enough prompts to complete ONE, maybe TWO tasks, if you're asking for a basic summary. It is NO WHERE near enough prompts to explore any-type of advanced feature, and when I tried the Video and Image generating resources it advertises that are available(Was the original thing that caught my interest) It continuously came back as "UNAVAILABLE AT THIS MOMENT, Please try again later, or upgrade to Pro". So I used my 5/5 prompts idly assuming the 5/5 would refresh the next day... Wasn't the case! Waited an entire 7/7 days an actual calendar week, not just a 5 day work-week, and the amount of available free prompts is still 0/5. So I was never able to actually sample the ORIGINAL content I wished to asertain the quality of... and at several hundred of dollars per month, this is an absurd price tier for their services, and no-way to subscribe to a certain AI-Tool while opting out of the others which you can aquire from variuos sources for ACTUALLY FREE. You can only subscribe to the entire bundle or nothing. This "ALL OR NONE" pricing scheme is aggrecious to say the least, upright USURY and false advertisement of their "Free Tier" and rather disappointing... I could see if you prioritized those attempting to sample the advanced features with only 5/5 free prompts available!! I mean COME ON!! If someone attempting to ascertain the quality of your product is going to provide such an effect against your available bandwidth that 5 free prompts are going to prevent paying customers from accessing your product line by the added latency it is rather shaking to the core and says a tremendous amount about your organizations available resources to provide to your paying tiers!! I can't believe you only have 250 ratings.. I'm guessing ChromeStore removes your review after you uninstall... So I'll have to leave this useless junk installed in my extensions and disabled. So some actual ratings are generated, against your fluff 5star ratings of people who actually enjoyed your limited and handicapped experience.

I found the Casper AI extension to be highly disappointing in its understanding of context and intent. It often provided irrelevant responses or failed to grasp the nuances of the conversation. This resulted in frustrating interactions where I had to repeat myself or correct its mistakes frequently
