This guide covers everything you need to manage your NP Chat plugin. If something isn’t working or you’re not sure what to do, contact Alex at Nörtti paikalle — details at the bottom.

What the plugin does

NP Chat adds a floating chat widget to your WordPress website. Visitors can open it and have a conversation with an AI assistant that knows about your company, services, and pricing. When a visitor shows interest, the assistant collects their contact details and sends you an email with everything you need to follow up.

The assistant runs on Claude (made by Anthropic). It only knows what is in your knowledge files and settings — it does not invent information.

Prerequisites

Before you start:

• A self-hosted WordPress website (WordPress.com does not support custom plugins)
• Administrator access to the WordPress dashboard
• An Anthropic account with billing enabled
• An SMTP plugin installed and configured (e.g. WP Mail SMTP, Postmark) — this ensures lead notification emails are delivered reliably

Getting an Anthropic API key

Create an account

1. Go to console.anthropic.com and sign up
2. Add a payment method under Billing
3. Navigate to API Keys and click Create Key
4. Copy the key immediately — it is only shown once

Billing and cost

You are charged per message sent and received. For a typical small-business website with moderate traffic, costs are usually well under €5/month. Anthropic provides a usage dashboard so you can monitor spend.

Auto-reload: Under Billing → Auto Reload, set a threshold (e.g. when credit drops below €5, reload €20). This prevents the widget from going offline if your credit runs out.

If the widget goes offline

If your Anthropic credit runs out, the widget silently disappears from your website until the account is topped up. Set up auto-reload to avoid this.

Plugin installation

1. Download the np-chat.zip file provided by Nörtti paikalle
2. Log in to your WordPress dashboard
3. Go to Plugins → Add New → Upload Plugin
4. Select the zip file and click Install Now
5. Click Activate Plugin

The plugin will not appear on your website until an API key is entered.
