Both tools build calculators and quizzes. The difference is what happens after someone uses one. Outgrow captures a lead. ConvertSite qualifies a buyer.

The real purpose_
What each tool is actually built for
Both build calculators and interactive tools, but the use cases diverge quickly when you look at what happens after the interaction.
Outgrow started as an interactive content marketing tool.
Its core job is helping marketing teams create engaging, branded experiences (quizzes, assessments, polls, ROI calculators) that attract and capture leads.
The platform is designed around lead volume and content production: 1,000+ templates, deep analytics, marketing integrations, and a builder that lets teams produce multiple content pieces quickly.
ConvertSite is built around a different problem.
Most small and mid-size businesses lose sales because their website can't answer the most important question a buyer has: how much will this cost me?
ConvertSite turns your site into something that calculates prices, qualifies leads in real time, books appointments, and delivers a ready-to-convert inquiry, without a sales call in between. It's less about content volume and more about what happens when someone lands on your pricing page.

Outgrow
The Freelancer Limited plan at $22/month only allows quiz-type content.
Most businesses end up on the Essentials plan at $95/month before they have what they actually need: integrations, custom domains, and unlimited content.
The Business plan at $720/month is enterprise territory.

What's missing_
The feature Outgrow doesn't have
ConvertSite's Documents add-on (available now, $50/month) lets you automatically generate branded PDFs from calculator submissions: custom proposals, quotes, and cost breakdowns that get emailed to the visitor the moment they complete the tool. Outgrow has no equivalent.
For service businesses that currently send quotes manually after every inquiry, this closes that loop entirely.

The key difference_
What happens after the interaction
With Outgrow...
The interaction captures a lead (name, email, quiz result) and hands it to your CRM or email sequence. The lead is warm but unqualified in terms of buying intent. Your sales team still has to do the work of understanding what the person wants and what it will cost them.
With ConvertSite...
The interaction is the qualification. By the time someone submits, they've seen their price, selected their options, answered the qualifier questions, and made a decision. The inquiry that arrives is pre-qualified, price-aware, and ready to move. With the Documents add-on they already have a branded proposal in their inbox. That's a fundamentally different sales motion.
