RelayCard places cards _inside_ your content at heading boundaries — after enough context has been built, before the next section begins. Cards only fire when a post has a featured image, keeping quality consistent. **Features:** * **Image-dominant by design** — the image stops the scroll, the title closes the click * **Heading-aware injection** — counts H2/H3/H4s and scales card placement automatically. Short posts get 1 card, long posts get 2. Nothing gets forced. * **5 card styles** — Split, Overlay, Cinematic, Minimal, Story * **3 font categories** — Sans-serif, Monospace, Script * **3 image ratio presets** — 50/50, 60/40, 70/30 * **AI hook title generation** — optional BYOK (Gemini, ChatGPT, Claude). Rewrites post titles into punchy hook titles automatically. * **Card title custom field** — override the title per post with your own hook * **SEO plugin aware** — detects RankMath, Yoast, AIOSEO titles automatically * **Live admin preview** — see your card render in real time before saving * **Zero setup friction** — CSS auto-enqueues on activation, no shortcodes needed * **Featured images required** — cards only fire when a post has a featured image, keeping quality high **Card Title Priority Stack:** 1. `card_title` custom field (manual override) 2. SEO plugin title (RankMath Yoast AIOSEO) 3. AI generated hook title (optional, BYOK) 4. Post title (always available fallback) **Card Styles:** * **Split** — image left, text right. Classic editorial card. *** Overlay** — full bleed image with gradient overlay and title on top. High visual impact. * **Cinematic** — wide image, centered title overlay. Maximum eye candy.*** Minimal** — no image, styled text card with accent border. Clean and fast. * **Story**— image top, text below. Mobile-first vertical layout. **AI Hook Title Generation (optional):** Bring your own API key from any of these providers: * Gemini (Google AI Studio — free tier available) * ChatGPT (OpenAI) * Claude (Anthropic) No key required. Cards work without AI. AI just makes the titles punchier. ### External Services This plugin optionally connects to third-party AI providers to generate suggested card titles.

Upload the `relaycard` folder to `/wp-content/plugins/` 2. Activate the plugin through the Plugins screen in WordPress 3. Go to **Settings RelayCard** to configure your card style, colors, and optional AI title generation 4. Cards will automatically appear in single posts with 4 or more headings and featured images ## FAQ ### Does RelayCard work without AI? Yes. AI hook title generation is completely optional. Cards fire on all qualifying posts using the post title (or SEO title if a plugin is detected) as the card title. ### What counts as a qualifying post? A post must have at least 4 headings (H2, H3, or H4) and a featured image for cards to fire. Posts with fewer headings or no featured image are skipped. ### How many cards appear per post? Posts with 4-5 headings get 1 card. Posts with 6 or more headings get 2 cards. The plugin scales automatically — nothing is hardcoded. ### Where exactly do the cards inject? Cards inject _before_ trigger headings — not after them. This means the card acts as a visual break between sections, not a disruption right after a heading. Mid- content, between sections, exactly where a reader pauses. ### Can I set a custom title per card? Yes. Add a custom field named `card_title` to any post. That value takes priority over everything else including AI generation. ### Which SEO plugins does RelayCard detect? RankMath, Yoast SEO, and All in One SEO (AIOSEO) — checked in that order. ### Will RelayCard slow down my site? No. The related posts query uses `no_found_rows` and `ignore_sticky_posts` for performance. CSS is only enqueued on single post pages. AI title generation uses a short 8-second timeout and fails gracefully with no impact on page load. ### Does RelayCard add nofollow to links? Cards link to your own posts — these are internal links and do not need nofollow. The attribution link to engineeredai.net is a standard dofollow link. ### Can I remove the attribution? The attribution (`// built with RelayCard — engineeredai.net`) is present on the free version and cannot be removed. It is minimal, monospace, and low-opacity — most readers won’t notice it. A premium version with attribution removal may be available in the future. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “RelayCard — Inline Related Post Cards” is open source software.
