What is a paywall?
A paywall is a monetisation mechanism that restricts access to content or features until a user pays or subscribes.
The types
- Hard. Nothing is accessible without payment. Maximum revenue per user, minimum reach and no organic discovery.
- Soft or freemium. A useful free tier with paid features above it. The dominant model in software.
- Metered. A number of free uses, then payment. Common in publishing, and increasingly in AI products.
- Dynamic. The threshold varies by user, based on predicted willingness to pay.
The trade-off
A paywall trades reach for revenue per user, and where you set it determines which business you are in.
Set it too tight and growth stalls — nobody discovers the product, nothing gets shared, and organic acquisition disappears. Set it too loose and the free tier satisfies most needs, so nobody upgrades. The right threshold is where the free tier is genuinely useful and the paid one is genuinely necessary for the user's actual job.
Paywalls for AI products
AI products face a harder version of this than most software, because the free tier has real marginal cost. Every free query consumes inference, so a generous free tier is a direct and growing expense rather than a near-zero one.
That pushes AI products toward metering — a number of free messages or a rate limit — rather than feature gating, because the cost scales with usage rather than with which features are unlocked.
The complication is that advertising and paywalls interact. Advertising on the free tier offsets its cost, and may either motivate the upgrade or annoy the user into leaving before they consider it. Both effects are real and they run in opposite directions, which is why the free-tier playbook and monetizing free-tier users without killing retention are worth reading before setting either.
Common questions
Do paywalls hurt SEO?
Hard paywalls do, because crawlers see nothing. Metered and soft paywalls generally do not, provided the accessible content is genuinely indexable and you are not showing crawlers something users cannot see.
Should an AI app run ads and a paywall?
Commonly yes — advertising on the metered free tier, ad-free above it. The design question is whether the advertising motivates upgrades without driving churn first, which is measurable on the same cohort.
