WooCommerce · Shopware Two things your shop is missing
Your customers get no advice and the assistants people now ask instead cannot read your products. Nexxus Butler does both: from the same data, in one plugin.
In early access, not for sale yet.
Hiking boots for wet trails, size 43, under €150?
Fully waterproof or is water-resistant enough?
Fully waterproof.
Readable for AI assistants
People ask ChatGPT and Google for products now. Those assistants judge your range by machine. So Butler publishes your product data in machine-readable form: as llms.txt and as Schema.org structured data. A monthly report is planned. Butler will ask assistants real buying questions from your field and record whether you were named.
Connect once
On WooCommerce, click “Connect with Nexxus”. You get a sign-in code by email, not a password. If you have no account, one is created. Then the rest sets itself up without theme work. Large shops need a few minutes for the first sync. The plugin only reads published content from your shop. It does not read customer accounts or orders.

Pricing
Conversations, products and features grow with the price. Once all conversations and the buffer are used up, the assistant finishes the ongoing ones. After that it answers in economy mode: for each question it shows up to three matching products, without follow-up questions or answers from your shop pages. Upgrades are never automatic: if you need more, you top up conversations.

Guided product finders Guided flows such as a gift finder or size advisor. You define the questions, Butler leads the way. | planned | planned | planned | |
Sales advisor in your shop Advises from your actual inventory: your prices, your availability, your copy. Never invents a product you don't have. | ||||
Comparisons, cart, coupons Puts products side by side, adds to the cart on request and offers coupons you have approved for it. | ||||
Getting found Schema.org markup, llms.txt and clean structure. Created during the catalogue sync, working from day one. | ||||
Getting understood Planned: Butler picks the attributes out of your descriptions and publishes them in machine-readable form. | planned | planned | planned | |
Visibility report Which AI bots visit your shop, which pages they read and whether you are indexed in Google, Bing and Brave. | planned | planned | planned | |
Getting queried (MCP) Your own MCP endpoint: third-party assistants query availability, price and fit live. | planned | planned | ||
Citation monitoring Monthly test questions from your field: are you named in the assistants' answers or is your competitor? | planned | |||
Data quality audit Per product: what's missing, what contradicts itself, what's outdated. Nothing gets changed. | ||||
Accessibility audit Where your shop falls short of the European accessibility rules, as a to-do list. | planned | planned | planned | |
Improving content Reworks the product description and short description, plus the image descriptions (alt texts). On Start or Growth, add one of the packages below. Pro includes 150 products a month. Nothing reaches your shop before you approve it. | add-on | add-on | 150 per month | |
Auto mode for approved areas Improvements go live without individual approval, but only in areas you name explicitly. Always switchable off, off by default. | planned | |||
Analytics and reports You see how many conversations there were, how many ended with a recommendation and how many found no match. Plus a list of requests your range has nothing for. | ||||
API and SDK For headless shops and apps: embed Butler through the SDK and the REST or WebSocket API instead of the web widget. | planned | planned | ||
“powered by” removable Today the widget carries no Nexxus note. A “powered by Nexxus” note is planned for the smaller tiers. From Growth on, that will be your call. | planned | planned | ||

A conversation is a whole visitor dialogue, not a single message. Unused conversations roll over to the next month (up to one month's allowance) and a ten percent buffer is always free.
Enterprise: own instance, own terms. Extra conversations from €9, see below. Talk to us
Top up conversations
Crossing the limit doesn't force an upgrade. Small packs instead.
- With any paid plan, from Start.
- Your monthly allowance is used first, then the top-up. Nothing goes to waste.
- Topped-up conversations never expire, not even at the turn of the year.
- And nothing ever gets switched off: if an allowance runs dry, the assistant finishes ongoing conversations and then answers in economy mode. Upgrades are never automatic. Only after three months clearly above the limit does the dashboard suggest the move, with the maths attached.
Reworking your product texts
One-off work alongside the subscription: your catalogue, properly reworked once. Priced separately because it replaces work instead of running continuously.
by hand: 42 hours
by hand: 208 hours
by hand: 833 hours
by hand: 4,167 hours
By hand means €15 and 20 to 30 minutes per product: reading it, understanding it, writing the description and short description, describing the images. That is why most shops never do it.
Add it to Start or Growth. Pro already includes 150 products a month.
What it costs you today
By hand, one product text costs €15 and 25 minutes. That is what a copywriter charges. Butler does the whole catalogue in one night. Approving stays with you: 20 seconds per product, an afternoon for 500.
The Butler figure is not zero: the run happens overnight, but every suggestion wants looking at. Counted at 20 seconds each.
Where your data lives
Butler runs on our own servers in Germany: website, dashboard, database and the search across your catalogue. Fonts are served from there too. We use no third-party visitor analytics. What the AI writes is generated by Scaleway in Paris, using the Mistral Medium 3.5 model: sales advice in your shop, suggested texts and image descriptions. The model is made by Mistral AI and run by Scaleway. Mistral AI has no access to the data. Scaleway receives what the answer needs from your shop and from documents you have uploaded. In sales advice, the conversation so far goes along too. For an image description, Scaleway fetches the image itself from its public address. The plugin does not read customer accounts or orders. Technically it could. It only asks your shop for published content. You can check that in the source code.
- Servers in Germany, the AI at Scaleway in Paris. Scaleway receives the conversation plus the details the answer needs from your shop and your documents.
- Customer accounts and orders are never read. The plugin only asks for what is public in your shop.
- On WooCommerce, you can see what the plugin sends. The plugin page lists what is sent and what never is.
- No training on your data. Not our models and not anyone else’s.
- Watch and decide. You see every suggested text improvement and how your conversations turn out. Nothing goes into your shop until you approve it.
Butler is being built in the open
It runs and it is tested against real shops. It is not for sale yet. Sign up and you will hear from us when it is. You will pay the price of the tier you picked today.
