The real purpose_
What each tool is actually built for
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.

What's missing_
The feature Outgrow does not 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.
What a customer actually experiences
A visitor completes your pricing calculator, sees their quote on screen, then immediately receives a branded PDF proposal in their inbox: itemised, on-brand, and ready to share with their team. No manual follow-up. No "we'll send a quote within 24 hours." The sale moves faster because the buyer has everything they need the moment they finish the tool.

The key difference_
What happens after the interaction
With Outgrow...
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.
