Gistty is a free Chrome extension that summarizes Amazon product reviews, explaining buzzwords and cultural context so you can shop faster.

Gistty is a free Chrome extension that summarizes product reviews on Amazon, letting you judge a product’s quality and relevance without reading hundreds of reviews. It breaks feedback into short snippets, highlights key insights, explains jargon and buzzwords, and notes the cultural context around a product.
Once installed, the extension works automatically on any Amazon product page. It currently supports Amazon.com only, though the team plans to expand to other marketplaces such as eBay or AliExpress. Gistty uses generative AI models, including GPT and Claude, to produce fast, ad-free summaries. It is free to install and does not require a credit card.
Gistty launched as a Chrome extension aimed at making it easier for shoppers to evaluate products on Amazon. The founders wanted to help shoppers quickly determine whether a product is good and relevant to their needs, using generative AI to condense reviews into clear, actionable summaries.
