Description

ReplyMind integrates OpenAI (GPT) and Anthropic Claude directly into your WordPress comment workflow. Generate thoughtful, on-topic replies to reader comments without leaving your admin dashboard. Replies are posted as the actual post author — complete with their avatar and name — making every response feel personal and authentic.

Two reply modes:

Suggestion Mode — The AI drafts a reply. You review it, edit if needed, and publish with one click. Full control, none of the typing.
Auto Reply Mode — Replies are posted automatically as soon as a new comment is approved. Great for high-volume sites.

Key features:

Author-aware replies — replies are attributed to the post author (with their avatar and name), not a generic site name
Supports OpenAI (GPT-4o Mini, GPT-3.5 Turbo, GPT-4o, GPT-4 Turbo, GPT-4) and Anthropic Claude (Haiku 4.5, Sonnet 4.6, Opus 4.6)
Five reply tones: Professional, Friendly, Casual, Empathetic, Formal
Three response lengths: Short (2-3 sentences), Medium (1 paragraph), Detailed (2-3 paragraphs)
Reply language: Auto-detect or choose from 10 supported languages (English, Spanish, French, German, Italian, Portuguese, Hindi, Arabic, Japanese, Chinese)
Custom system prompt to tailor the AI instructions to your brand voice
AI Reply column in the Comments list showing draft status, published status, or errors at a glance
Batch processing — generate AI replies for hundreds or thousands of existing comments with a live progress bar
Bulk publish — publish all pending AI drafts in one click (Suggestion Mode)
Reply log — track every generated reply with timestamp, post, and full reply text
Developer filter replymind_send_comment_data to prevent specific comments from being sent to the AI

FAQ

Does this plugin post replies automatically?

Only if you choose Auto Reply Mode in Settings. The default is Suggestion Mode, which saves a draft for you to review before anything is posted publicly.

Which AI provider should I use?

Both work well. OpenAI’s GPT-4o Mini and Anthropic’s Claude Sonnet 4.6 offer the best balance of quality and cost. If you are unsure, start with GPT-4o Mini.

Can I edit the reply before it goes live?

Yes. In Suggestion Mode, click Edit & Publish on any comment row to open an editable modal pre-filled with the AI draft. Edit freely, then click Publish Reply.

What is the Batch Process tab for?

If you install the plugin on a site that already has hundreds or thousands of comments, the Batch Process tab lets you generate AI replies for all of them at once with a live progress bar. In Suggestion Mode you can then bulk-publish all drafts from the same tab.

Will this break my existing comments?

No. The plugin only adds replies as child comments. It never modifies existing comment content.

Is comment content sent to a third party?

Yes. Comment text is sent to the AI provider you select (OpenAI or Anthropic) to generate a reply. Please review the External Services section above and each provider’s privacy policy. Use the replymind_send_comment_data filter to exclude specific comments from being processed.

Can I use my own system prompt?

Yes. The System Prompt field in Settings lets you provide custom instructions the AI follows for every reply. For example: “You are a customer support agent for Acme Co. Always offer to escalate to human support if the customer is frustrated.”

How are API costs calculated?

Each reply generation is one API call. Token usage depends on comment length, post context, and reply length setting. GPT-4o Mini and Claude Haiku 4.5 are the most cost-effective models.

Whose name appears on the AI reply?

The reply is attributed to the post author: their WordPress display name, avatar, and email are used. If a post has no author, the reply falls back to the site name and admin email. Multi-author blogs work automatically: a comment on Jane’s post gets a reply from Jane, a comment on John’s post gets a reply from John.

I see a provider/model mismatch warning. What do I do?

Go to Settings > ReplyMind and make sure the selected Model matches the selected AI Provider. OpenAI models start with gpt-; Claude models start with claude-.

How can I stop a specific comment from being sent to the AI?

Use the replymind_send_comment_data filter in your theme’s functions.php or a custom plugin:

add_filter( 'replymind_send_comment_data', function( $allow, $comment ) {
    // Return false to skip this comment.
    if ( (int) $comment->comment_post_ID === 123 ) {
        return false;
    }
    return $allow;
}, 10, 2 );
