Two popular form builders compared on the same 25-row feature matrix and pricing, with FormBuilder shown as a third column so you can see another option to consider.
Overview
Fillout is a newer form builder built around one idea: your form should live on top of the database you already use. Connect an Airtable base, Notion database, HubSpot object, Salesforce record or Google Sheet, and Fillout maps fields both ways — it can prefill from existing records, create new ones, and update them on submit. For teams running operations out of Airtable or Notion it is often the missing "front door" for their data.
The builder itself is polished and quick, with a large field catalogue (50+ types including payments, scheduling, signatures and PDF generation), conditional logic, calculations, multi-page flows, quizzes and a growing set of AI features for drafting forms. It also supports login-gated forms, partial-submission capture and PDF output, which pushes it toward internal tools and client portals as much as public forms.
involve.me (originally brandquiz) is not a general form builder so much as an interactive-content builder. Its "funnels" are multi-step experiences — personality and product-recommendation quizzes, price and ROI calculators, lead-magnet surveys, payment and booking flows — that live on a hosted landing page, embed, or pop-up and push leads into your CRM or email tool. Outcome logic, answer scoring, calculators and A/B testing are core, and 350+ templates are built around marketing outcomes rather than form types.
The pricing reflects that focus. Plans are metered on live funnels and seats: Start (3 live funnels, 1 user), Grow (5 live funnels, 2 users, branding removed, 1 custom domain), and Scale (25 live funnels, 5 users, 3 custom domains, A/B testing, Salesforce), with Enterprise from $499 / month. On annual billing that is $29, $69 and $139 a month; month-to-month is roughly $49, $99 and $199. A free account allows 2 live funnels and 50 submissions or 500 visits a month with 30-day retention and no exports, integrations or logic jumps.

Fillout is a fast, modern form builder whose signature trick is writing responses straight into Airtable, Notion, HubSpot, Salesforce and Google Sheets — with a very generous free plan. involve.me is a marketing-first builder for quizzes, calculators, lead funnels and surveys — priced per live funnel and aimed squarely at lead generation rather than everyday forms. Fillout is best for teams that run on Airtable, Notion, HubSpot or Salesforce and want forms that write directly to those records; involve.me is best for marketers building lead-qualification quizzes, product finders and calculators.
FormBuilder is worth a look if you want an AI generator that drafts forms from a sentence, 100 free responses a month with overflow held rather than lost, Stripe payments with no platform fee, and a flat $39 / month Pro plan for 10,000 responses.
