The real purpose_
What each tool is actually built for
Interactive content for your marketing campaigns
Outgrow helps marketing teams launch interactive campaigns using a broad template library and lead-generation integrations. It supports personalised results, campaign landing pages and ways to pass customer data between experiences.
It is a strong fit when you want to add a quiz, assessment or calculator to the website and marketing setup you already use.
The website and the buying experience, built together
A home-improvement business could explain its services, let visitors select the work they need and show an estimated price before they request a quote. Your team manages the service pages and pricing rules in the same builder.
Start with one useful interaction or build the complete site. As your offer changes, update the explanation, options and calculation together.

What's missing_
The feature Outgrow does not have
A calculator can answer one question, but visitors may also need to understand your service, explore their options and decide what to do next.
ConvertSite lets you build those pages alongside the interactive experience. The team responsible for the offer can update the content and the rules behind the result in the same builder.
Outgrow can connect experiences and pass customer data between them. The reason to choose ConvertSite is the ability to build and manage the complete website around that journey, not a claim that Outgrow's tools must work in isolation.
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.
