zimplico

zimpliScribe brings AI-assisted writing directly into the WordPress editor — proofread existing copy, translate to your target language, expand or shorten passages, or generate drafts from a prompt. Works in the Gutenberg sidebar, on a dedicated admin page, and as a Quick Capture widget for jotting ideas straight from your dashboard or your phone.
No AI provider keys in WordPress. The plugin connects to the zimplico.de API service, which holds the provider credentials server-side. You register your site once via a domain-ownership challenge (the same pattern Let’s Encrypt uses — no API keys to copy around), and you’re done.
Per-credit billing. Each request costs one credit. New sites get 25 welcome credits (these never expire) plus 5 free credits every month. Top up via the billing portal — no charges happen without your explicit action.
<h4>Features</h4>
<ul>
<li>Content Tool — text + intent prompt + suggestion chips (Proofread, Translate, Make shorter / longer). Combine chips as you go.</li>
<li>Quick Capture — a simplified, voice-friendly box (Memo · Proofread · Translate, then Save Draft) as a Dashboard widget and the default view on mobile. Record quick drafts from anywhere, hands-free with your keyboard’s dictation.</li>
<li>Image input — attach any image from the WordPress media library, or upload directly (mobile camera supported via OS picker). Sent alongside your text.</li>
<li>Insert image — adds attached images to the result as Markdown links; resolves to real <code><img></code> tags when saved.</li>
<li>Maximize mode — give the result panel the full width when you’re reviewing long output.</li>
<li>Save as Draft — create a WordPress post or page directly from the result.</li>
<li>Gutenberg sidebar — work on selected blocks: Send to AI, Replace Block, Insert After.</li>
<li>Per-site credits widget — current balance and renewal date in the admin header.</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Install and activate the plugin.</li>
<li>Visit WP admin → zimpliScribe → Register Site. The plugin generates a one-time challenge token.</li>
<li>The API verifies the token by calling back to your site’s public REST endpoint — same approach as Let’s Encrypt’s HTTP-01 challenge.</li>
<li>Your site goes active with 25 welcome credits plus 5 free every month.</li>
<li>Use the Content Tool tab or the Gutenberg sidebar.</li>
</ol>
No API keys are stored in WordPress at any point. The plugin holds an opaque <code>site_id</code> that the API validates per-request against the registered domain via the browser’s <code>Origin</code> header.
<h4>Privacy</h4>
Text and images submitted via zimpliScribe are sent to the zimplico.de API and forwarded to the AI provider for processing. Content is not stored long-term by zimplico.de — see the privacy policy at https://zimplico.de/privacy.html for specifics on retention, processing, and provider details.
<h4>External services</h4>
This plugin relies on external services to provide its functionality. No data is sent before you actively register your site, and no AI request is sent until you submit one.
zimplico.de API (https://api.zimplico.de/zimpliscribe) 
* Purpose: site registration, credit accounting, AI request proxying, and billing portal links. 
* Data sent: site URL (during registration), opaque per-site token (on every request), the text and any images you submit for processing. 
* When sent: registration is triggered when you click Register Site. AI requests are sent only when you click Send to AI or Generate page. 
* Terms of service: https://zimplico.de/terms.html 
* Privacy policy: https://zimplico.de/privacy.html
xAI Grok (https://api.x.ai) 
* Purpose: AI model that processes your text and image prompts. zimplico.de forwards your request to xAI on your behalf — the plugin does not call xAI directly and no xAI credentials are stored in WordPress. 
* Data sent: the text and any images included in your AI request, plus an internal system prompt. 
* When sent: only when zimplico.de receives an AI request from your site. 
* Terms of service: https://x.ai/legal/terms-of-service 
* Privacy policy: https://x.ai/legal/privacy-policy
<h4>Data we do NOT store</h4>
<ul>
<li>No AI provider API keys are ever held in WordPress.</li>
<li>No personal data about WordPress users (authors, admins, commenters) is sent — only the content you explicitly submit in the plugin UI.</li>
</ul>
