Sumzy vs the other Shopify AI review summary apps

Judge.me ships an AI summary on its Awesome plan ($15/mo), in two places that behave differently. In the Reviews Carousel it is a store-level summary: you click Generate summary yourself, it reads up to 500 published reviews from a date range you choose, and it is available in English only. In the Review Widget it is per-product and now called AI product review insights: it reads up to 100 of the most recent published reviews for that product, refreshes on its own every 30 days, and the summary text is translated when multi-language widgets are enabled. Both need at least five published reviews with body text, both are labeled as AI-generated, and neither is editable.

Where Sumzy differs: it writes the summary in your store’s language, chosen from 43, and it shows recurring themes as named aspect chips with a mention count on each. On the Professional and Business plans you read and edit the wording before it goes live, which Judge.me’s own documentation says its summaries do not allow. Sumzy checks for new reviews on a regular schedule rather than on a fixed 30-day clock, and it saves the summary to your own store, so product pages stay fast whatever the backend is doing.

Loox does not ship a narrative AI summary. Its AI suite covers review sorting, sentence-level highlights, translations, replies, and image alt text. That is useful, but none of it is a synthesized paragraph for shoppers.

If you collect with Loox and want a real summary today, this comparison has no Sumzy answer for you yet.

Okendo includes AI summaries on its Growth plan ($119/mo). The merchant can regenerate and approve before the summary goes live. Okendo’s copy says the summary covers what customers love and what they do not love.

If you already pay for Okendo Growth, you already have a summary. Check it before adding another app.

Yotpo includes AI summaries on its Pro plan ($119/mo). The format is topic-based with per-topic sentiment counts. Its public materials describe multilingual support as architecturally possible rather than confirmed as shipped.

If you already pay for Yotpo Pro, the same advice applies: check what you have before adding another app.

Reviewcap only summarizes; it does not collect. Its standout is language breadth: it documents support for 80 or more languages across the Shopify language set, the widest coverage of any app here. It reads Fera, Judge.me, Loox, Okendo, Reviews.io, and Yotpo. Pricing runs from a permanent free plan for stores with up to 200 reviews through paid tiers at $5, $10, and $25/mo for larger review pools.

Choose Reviewcap if broad language coverage matters, or if a free plan for a smaller store is the deciding factor.

AIRA summarizes only, highlights pros and cons, and outputs in English, French, and German. It reads Judge.me, Loox, and Stamped. A permanent free plan covers 10 product analyses at a 50-review depth; paid plans step from $2.99 to $9.99/mo for higher counts and deeper reads. Its App Store listing also mentions collecting “feedback from reliable sources” for products with no reviews, a feature the listing does not fully document.

Choose AIRA if you sell in English, French, or German, want a free plan with a cheap upgrade path, and collect with Judge.me, Loox, or Stamped.

Slon adds AI summaries and sentiment analysis, and also drafts AI-enhanced review request emails, which edges into collector territory. It reads Judge.me, Yotpo, Okendo, and Shopify’s default review system. There is one paid tier at $9.95/mo (or $100/yr) with a 7-day trial and no permanent free plan. Its App Store listing shows the broadest data scope in this comparison, covered above.

Choose Slon if you want summaries and AI-drafted review requests together, and you use one of its four supported review platforms.

TagWise adds summaries, review tagging, and analytics. It reads Judge.me, Loox, Yotpo, and accepts CSV imports from any provider. Output is documented as English only. At the time of writing it offers a free plan and no paid tier.

Choose TagWise if you want free summaries plus tagging and your store operates in English.

Platoria works differently from every other app here: it does not summarize your store’s own customer reviews. It generates AI summaries from external internet sources such as Amazon, AliExpress, and other stores, from links the merchant supplies, and displays them as product social proof.

Sumzy summarizes the reviews already on your own store, which is a different job, not a better version of the same one.
