<a href="https://codoc.jp" rel="nofollow ugc">codoc</a> is a simple and powerful WordPress paywall plugin that enables creators to sell paid articles, offer Reader Plans (Subscription / Membership), and accept tips.
Originally built for Japanese creators, codoc is also fully compatible with users in the US/EU. 
Payment is processed via Stripe, and buyers worldwide can purchase using a valid credit card (currency: JPY/USD/EUR).
After setup, the plugin adds a codoc block※ to the post editor. 
※Compatible with both Gutenberg and the Classic Editor (TinyMCE).
<h3>How it works</h3>
Content placed below the codoc block becomes the paid section and is hidden from non-buyers. 
Content placed above remains freely available.
The codoc block: 
– displays the purchase interface 
– handles buyer authentication 
– allows per-article settings such as price or Reader Plan availability 
– all revenue/customer management is available on codoc.jp
