Amazon’s new AI review summarizer could help you empty your pockets even faster

Have you ever been shopping on Amazon, but found yourself too lazy to read the user reviews at the bottom of a product listing? Well, you’re in luck because Amazon has recently implemented a generative AI to its platform that will summarize reviews.

The company states the AI tool will offer short paragraphs “on the product detail page” highlighting key features as well as overall “customer sentiment”. Customers can quickly scan the short block of text to get an idea of whether a product is good or not instead of having to read dozens of reviews. Amazon states in its announcement you can direct the AI a bit by having it focus on specific “attributes.” Say you want a smart TV that’s easy to use. Users can select the “Ease of use” tab to have the summarizer specifically talk about that attribute or something else like its performance is while streaming content.  

Work in progress

Unfortunately, the AI feature was unavailable to us as we were excluded from the rollout, but The Verge had access. In their report, The Verge claims it saw the tool show up on listings for “TVs, headphones, tablets, [plus] fitness trackers.” It isn’t very consistent either. They state the summarizer is available on the Galaxy Tab A7, but not the Galaxy Tab A8. Also, it appears Amazon’s AI heavily favors writing positive content, as it spends “less time on the negatives.”

We reached out to Amazon with several questions about the new tool, including if there will there be a desktop version and if the company plans on providing links directing users to the AI's source reviews. Google’s SGE tool does this for the generated content it produces. It’d be nice to see sources in the paragraph. However, Amazon has nothing more to share at the moment.

Analysis: Remaining skeptical

Amazon has been dabbling in AI for a while now. Back in May, Amazon listed a job listing for a “machine learning focus engineer,” revealing the company is looking for someone to help develop an “interactive conversational experience” for its search engine. We could see the Amazon search bar one day offer a ChatGPT-like experience where you talk with the AI when looking for a product.

It would be wrong of us not to add a little asterisk to all this AI talk. As you may know, generative AIs are known to “hallucinate”, which is to say, they sometimes provide inaccurate information. It’s gotten to the point some experts believe this problem will never be fixed. So read the summarizer’s text with several grains of salt. As it turns out, you just can’t beat good old-fashioned human opinion – like the kind TechRadar provides every single day.

Brave Summarizer takes on Bing and ChatGPT at the AI search results game

Hopping on the AI train, Brave is incorporating its own AI-powered search function to its web browser called Summarizer – similar to what Microsoft recently did to Bing.

The new feature “provides concise and to-the-point answers at the top of Brave Search results”. For example, if you want to learn about the chemical spill in East Palestine, Ohio, Summarizer will create a one paragraph summary of the event alongside some sources for you to read. Unlike Microsoft which only uses ChatGPT for Bing's chatbot, Summarizer uses three in-house large language models, LLMs for short, based on retrained versions of the BART and DeBERTa AI models to create the search-results snippets.

Retraining AI

To simplify the technology behind them, BART and DeBERTa are generative writing AIs like ChatGPT that have been specially trained to take into account word positioning as well as context so the text output reads well. What Brave did is take those models and retrain them using its own search result data to develop Summarizer.

Summarizer’s training regiment is a three-step process, according to the announcement. First, Brave taught the LLMs to prioritize answering the question being asked. Then, the company utilized “zero-shot classifiers” to categorize results so the given information is relevant. The final step helps the models rewrite the snippet so it’s more coherent. The result is an accurate answer written succinctly with multiple sources attached.

Be aware the feature is still in the early stages. Brave states Summarizer only utilizes about 17 percent of search queries to formulate an answer, but there are plans to scale that number even higher for better paragraphs. Its accuracy needs some work, too. The company admits Summarizer may produce what it calls “hallucinations” which are unrelated snippets mixed in with results. Plus there's the possibility of the feature throwing in some “false or offensive text” into an answer.


Summarizer is currently available to all Brave Search users on desktop and mobile with the exception of the Brave Search Goggles. It’s disabled there. You can turn it off anytime you want by going into the browser’s settings menu. The company is also asking users to give some feedback on how it can improve the tool. 

We tried out Summarizer ourselves, and as cool as it is, it does need some work. Not all search results will give you a snippet as it depends on what you ask, as well as which news topics are making the rounds. The East Palestine, Ohio chemical spill, for example, is currently a hot button issue so you get Summarizer working just fine there. However when we asked about the recent cold snap in Los Angeles and what’s going on with certain video game developers, we either got no summary or outdated information. But the latter did come with sources so it was at least accurate. Still better than having ChatGPT throw a temper tantrum or lie to your face.
