Octane AI vs Building Your Own Quiz
You want full control. Phoenix gives you most of it on day one: it builds the quiz from your Shopify catalog, checks every path, tracks revenue per answer and exposes an API. The part you keep is the part worth keeping.
The real cost of building your own
Custom quiz builds sound appealing until you add up the true costs. Here is what brands typically spend when building in-house:
Development
Quiz pages, branching logic, product matching and the storefront embed
Design
Quiz flow, results page and mobile views, then every restyle after
Integrations
Shopify catalog and customers, Klaviyo, Attentive, Postscript, analytics
AI
Catalog-aware recommendations, copy that adapts to answers, image analysis
Testing and QA
Every answer path, every browser, every out-of-stock product
Ongoing maintenance
Bug fixes, catalog changes, Shopify API changes
And that is before opportunity cost, bug fixes, or the features you did not know you needed until launch.

Think about what you are actually building
A product recommendation quiz is not a form. It is branching logic, four ways to pick products, order matching that runs for weeks, and a profile store your marketing tools read from.
Developer time adds up fast
At $150/hour (agency rate), that is $133,500 in development costs alone.
When does custom make sense?
We believe in being honest. Here are the rare cases where custom might be the right call:
Enterprise with unique requirements
If you have proprietary systems, compliance needs and a dedicated engineering team, custom might make sense. Even then, the REST API, webhooks, storefront JS API and MCP server on Plus and Enterprise cover most of what teams build around a quiz.
You need something we do not do
If you need a quiz for something outside ecommerce, like medical diagnostics or industrial applications, we are probably not the right fit. For Shopify stores, we have seen it all.
For everyone else: Octane AI
For most Shopify brands, Octane AI ships more than a custom build would, the same day, at a fraction of the cost. We handle updates, Shopify API changes and security, so your team can focus on the brand.
