Subpage is a lead capture gating system solving the silent list-building killer most content marketers ignore: valuable whitepapers, checklists, templates, and business cases getting consumed without capturing a single email address. Most marketers create lead magnets like PDFs, checklists, or guides then share them as direct downloads or open web pages—meanwhile thousands of visitors consume the content without joining their email list because there’s no friction forcing the opt-in, turning potentially valuable lead generation assets into traffic that vanishes without a trace. Subpage fixes this by converting any content into interactive multi-tab gated pages with a Notion-like editor requiring zero design skills, offering flexible gating options including full content locks, partial previews that require email for the rest, pop-ups, top bars, and file download gates, using AI to generate complete multi-tab lead magnets in minutes from simple prompts instead of manually formatting content, providing custom domain support and white-label branding so gated pages match your site perfectly, and integrating with Zapier, ConvertKit, and webhooks to route captured leads directly into your CRM or email platform without manual exports. Content creators sharing ungated guides that get thousands of views but zero subscribers, B2B marketers with whitepapers hosted as open PDFs losing qualified leads daily, and course creators giving away valuable resources without capturing contact information use Subpage to stop bleeding potential subscribers from high-traffic content assets that should be building their lists.

Gate any content type including whitepapers, checklists, templates, and business cases with flexible options from full locks to partial previews requiring email for complete access.

Generate professional gated content pages with AI in minutes by describing what you want instead of manually formatting and designing everything from scratch.
