Quinn and Tolstoy both put video on a Shopify store, but they are known for different things.
Quinn is known for TikTok-style vertical feeds that keep shoppers scrolling through products; Tolstoy is known for interactive video that branches on the viewer's choice.
Both use tiered plans based on views or orders, so the cheaper one depends on your traffic and the tier you land in, not the entry price.
Choose Quinn if you want a feed of many short clips; choose Tolstoy if you want guided, conversational video such as quizzes and product finders.
If you mainly want Reels and TikToks on product pages with product tags, a free-plan app such as SwipeReel covers that without a usage-tiered subscription.
Quinn is built around TikTok-style vertical video feeds on a Shopify store.
