Both tools build interactive funnels. The difference is what's in the box when you open it. Involve.me gates tracking, webhooks, and custom domains behind its top tier. ConvertSite unlocks them progressively, with no submission caps on any plan.
Both tools build interactive funnels. The difference is what's in the box when you open it. Involve.me gates tracking, webhooks, and custom domains behind its top tier. ConvertSite unlocks them progressively, with no submission caps on any plan.
Involve.me is a polished funnel builder with strong design tools and a wide library of interactive elements. The catch: features most marketers need from day one, including Google Tag tracking, webhooks, custom CSS, and A/B testing, are gated behind the $129/month Business tier.
ConvertSite starts with all core components on the Free plan, integrations unlock progressively from $50/month, and no plan charges by submission volume. If your primary use case is pricing calculators and quote flows, ConvertSite is the more direct fit at a significantly lower price.
Outgrow is a content marketing platform built for lead generation campaigns: quizzes, assessments, ROI calculators that attract and capture contacts.
ConvertSite is built for businesses that need to qualify buyers, show real-time pricing, and close sales without a sales call.
If you sell something with variable pricing or complex configuration, ConvertSite is purpose-built for that. If you're running content campaigns and need branded quiz funnels at scale, Outgrow has the depth.
Both build calculators, quizzes, and funnels, but the use cases diverge quickly when you look at what happens after the interaction.

Its core job is helping marketing teams produce interactive funnels at volume: quizzes, surveys, multi-step forms, and payment flows.
The platform is designed around variety and design control, with 300+ templates and strong customisation at each step. You build the funnel, a visitor completes it, you get a contact. What happens with that contact happens outside the tool.
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-act inquiry, without a sales call in between. It's less about capturing contacts and more about what happens when someone lands on your pricing page.

Involve.me's entry price looks low but the features you actually need are locked behind the most expensive plan.
You build for free on the Free plan (250 AI credits, all components, no publishing).
Starter at $25/month unlocks publishing, analytics, and submission emails.
Builder at $50/month adds your own custom domain and Zapier webhook.
Business at $100/month adds full Zapier, HubSpot, and removes ConvertSite branding.

The Starter plan at $29/month is limited to 5 funnels and one user. Google Tag Manager is a paid add-on.
Remove branding requires the Pro plan at $59/month, but you still won't have webhooks or tracking until Business.
Most marketers end up on the Business plan at $129/month before they have what they actually need: webhooks, custom domain, A/B testing, and custom CSS.

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. Involve.me has no equivalent.
For service businesses that currently send quotes manually after every inquiry, this closes that loop entirely.

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.
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.
