Quick Answer
For sleep brands and sleep product retailers: Sleepmaxing. Pre-built sleep quiz, sleep-attribute product tags, automatic bundle discounts at checkout via Shopify Functions. Ready in under an hour.
For general DTC brands building from scratch: Octane AI. The most flexible quiz builder with deep Klaviyo integration and conditional logic — but requires setup time and starts at $50/month.
For data-driven teams who want quiz analytics: RevenueHunt (Shop Quiz). Strongest analytics dashboard of the four, good for A/B testing quiz variants.
For video-first brands: Tolstoy. Not a traditional text quiz — it uses short shoppable videos to guide product discovery. A different format entirely.
If you're a sleep brand specifically, skip ahead to the Sleepmaxing section — the general-purpose apps in this list require you to rebuild quiz logic that Sleepmaxing ships pre-configured. If you're a general DTC brand comparing Octane AI and RevenueHunt, the comparison table below will save you time.

App-by-App Breakdown
Sleepmaxing is the only Shopify quiz app built specifically for sleep brands. Instead of building quiz logic from scratch, you install the app and a 5-question sleep quiz is ready to publish: sleep position (side/back/stomach/combination), temperature preference (hot/cold/neutral), firmness preference (soft/medium/firm), fill preference (down/synthetic/memory foam), and budget tier.
The quiz recommends products using sleep-attribute product tags. You tag your catalog once (sleepmaxing-position-side, sleepmaxing-temp-hot, etc.) and the quiz matches customers to products that fit their profile. The bulk auto-tagger handles the catalog work in one pass.
The unique capability: when a customer adds a quiz-recommended sleep system (pillow + mattress topper + accessory), Shopify Functions automatically applies a bundle discount at checkout. No coupon code required. This turns the quiz from a recommendation tool into an AOV driver — customers who buy two or more quiz-recommended products together get rewarded automatically.
Octane AI is the most established general-purpose product quiz builder for Shopify. You get full conditional logic (answer A shows question 3a, answer B shows question 3b), unlimited quiz variants, and deep native Klaviyo integration — quiz results push to subscriber profiles automatically, so you can segment email flows by quiz outcome.
The downside is setup time. You build the quiz logic from scratch, configure recommendation rules, map product tags to quiz paths, and test conditional branches before publishing. For a well-designed quiz covering 4–5 product attributes across a catalog of 50+ SKUs, expect 6–8 hours of setup. There's no pre-built quiz for any specific vertical.
At $50/month for the entry tier (capped by responses), Octane AI is priced for stores doing meaningful volume. The Klaviyo sync is the strongest in this list — quiz takers sync as segments, allowing email flows to reference quiz answers ("You said you're a hot sleeper — here's what that means for your pillow choice").
RevenueHunt's "Shop Quiz" app competes directly with Octane AI in the general-purpose tier, with one key differentiator: its analytics dashboard. Where Octane AI focuses on the quiz-building experience and Klaviyo integration, RevenueHunt gives you detailed per-question drop-off rates, recommendation click-through, conversion attribution, and A/B test results at the quiz level.
For teams that want to optimize quiz performance over time — testing question order, answer copy, recommendation logic — RevenueHunt's analytics make iteration faster. Setup time is similar to Octane AI (build logic from scratch), but the reporting payoff is stronger for data-focused teams.
RevenueHunt integrates natively with Klaviyo, Mailchimp, Attentive, and Drip. The entry plan at $39/month is slightly cheaper than Octane AI, though both scale with response volume. There's no free tier on either.
Tolstoy is a fundamentally different product: instead of text-based questions, it uses short TikTok-style videos where customers tap answers to navigate to product recommendations. The format works well for visually-driven product categories — fashion, beauty, home decor — where showing the product in context is as important as describing it.
For sleep brands, Tolstoy is a harder fit. Sleep product decisions are driven by comfort attributes (firmness, temperature, fill), not visual appeal. A customer choosing a pillow needs to know it's right for side sleepers who run hot — that's more clearly communicated with text questions than with a video of someone sleeping.
If you're a sleep brand considering Tolstoy for aesthetic differentiation, the tradeoff is worth examining: video production overhead per quiz variant, lower compatibility with sleep-attribute product tagging, and no automatic checkout discount. The starting price is lower at $19/month, but production costs for quality video content add up quickly.

Regardless of which app you install, five criteria determine whether a quiz actually drives conversions or just sits on your store unused:
1. Quiz length under 7 questions. Completion rate drops sharply above 7 questions. The data shows 68% average completion for 5–7 question quizzes and under 40% for 10+ question quizzes. If your quiz needs more than 7 questions to make a useful recommendation, the underlying recommendation logic is too complex — simplify the attribute matching first.
2. TAE architecture (async loading). Apps that inject render-blocking JavaScript into the page head add 100–400ms to LCP. In a PageSpeed-sensitive store, this matters. Theme App Extensions load asynchronously after the main page renders. Ask each app vendor how their widget loads before installing on a speed-optimized store.
3. Recommendation confidence, not just recommendation. The quiz result shouldn't just say "we recommend this pillow." It should tell the customer why: "Because you're a side sleeper who runs hot, you need a pillow with high loft and a cooling fill." Confidence in the reason drives add-to-cart. Apps that show a product card without explanation underperform apps that show a reasoning statement.
4. Automatic checkout discount (if applicable). Most quiz apps stop at the recommendation. If you want the quiz to also drive higher AOV — by rewarding customers who buy multiple recommended products together — you need either a quiz app that includes checkout discounts (Sleepmaxing via Shopify Functions) or a separate bundle app that integrates with the quiz app's logic.
5. Email capture on quiz results. The quiz result page is the highest-intent moment in a shopper's session. Every quiz app on this list can gate the result behind an email opt-in, or show the result with an optional email capture. For stores building their list, placing the email capture before the result (gated) converts at 20–30%. Placing it after (ungated, with incentive) converts at 12–18% — but produces higher-quality leads who've already seen their recommendations.
Frequently Asked Questions
Which Shopify quiz app is best for sleep brands?
Sleepmaxing is built specifically for sleep brands. It includes a pre-built sleep quiz (sleep position, temperature preference, firmness, fill type), automatic product tagging by sleep profile, and Shopify Functions-powered bundle discounts at checkout. Other general quiz apps require you to build the quiz logic from scratch and don't include sleep-specific recommendation logic or bundle discounts. See the setup guide →
How does a product quiz increase Shopify conversion rate?
Product quizzes lift conversion by removing purchase uncertainty — the main reason shoppers abandon without buying. For high-consideration products like mattresses, pillows, and sleep accessories, customers can't try before buying. A quiz recreates the in-store expert consultation, giving customers confidence before they add to cart. Research benchmarks show quiz-guided visitors convert 3–5x higher than unguided visitors. BedGear documented 490% conversion lift after implementing a sleep quiz.
What is the difference between Sleepmaxing and Octane AI?
Sleepmaxing is vertical-specific: it's a pre-built sleep quiz with sleep-attribute product tags and automatic Shopify Functions bundle discounts — built for sleep brands, ready to install and publish in under an hour. Octane AI is a general-purpose quiz builder for any DTC brand — you build quiz logic from scratch, configure integrations, and connect to Klaviyo manually. Octane AI is more flexible; Sleepmaxing is faster and more opinionated for sleep brands.
Do quiz apps slow down Shopify stores?
It depends on architecture. Apps that inject render-blocking scripts into the page head will add 100–400ms to LCP and hurt PageSpeed scores. Theme App Extensions (TAE) load asynchronously after the main page renders — zero LCP impact. Sleepmaxing uses TAE architecture. Check each app's technical docs before installing on a store optimized for speed.
Can a Shopify quiz app trigger automatic discounts at checkout?
Most quiz apps stop at the recommendation — they show which product to buy but don't automatically apply a discount when the quiz-recommended products are added to cart together. Sleepmaxing integrates with Shopify Functions to trigger an automatic bundle discount at checkout when quiz-recommended products are purchased together (e.g., pillow + mattress topper + sleep mask). This turns the quiz into an AOV driver, not just a recommendation engine. How Shopify Functions discounts work →
