In short_
Landingi helps marketers build, publish and optimise landing pages. It combines a drag-and-drop editor with AI generation, forms and campaign-testing tools.
ConvertSite builds interactive sites and pages that work for your business. Calculators, configurators and quote flows help each visitor get an answer or offer. The whole interactive flow uses native building blocks, with editable inputs, formulas and conditions in a visual DIY builder. Analytics, funnels and A/B testing are built in.
Both provide visual page editing. Choose ConvertSite when your team needs to manage the business rules behind the customer journey as directly as the design.
In short_
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.

What's missing_
The feature Landingi does not have
The page design is only one part of an interactive customer journey. Your rates, options and conditions determine what each visitor sees and what the offer becomes.
ConvertSite gives your team visual controls for that logic. Change a formula, add a selectable option or adjust a follow-up question, then test and publish from the same builder. Built-in analytics, funnels and A/B testing help you improve the same journey.
Landingi also has a visual page builder. Bespoke calculations and advanced interactions can use custom scripts or embedded tools; their rules need to be maintained in that implementation.
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.
