Frequently asked questions
What is Plugster?
We make your site readable by AI assistants such as ChatGPT, Claude, Gemini and Perplexity, and add a chat that answers your visitors. If you sell online, we also prepare your catalogue for the assistants’ shopping shelves. Everything starts from your public pages, and everything stays up to date on its own.
What is an llms.txt file?
A markdown index, at the root of a site, that tells an AI assistant what the site holds and where to read each page. We rewrite it at every update of your site, so it never lags behind it.
What is an MCP server?
MCP (Model Context Protocol) is the standard way for an assistant to use tools. Our MCP server gives assistants tools on your site: search, product lookup, live availability, reading a page. You choose which ones are switched on.
What is the chat on my site?
A bubble in your colours that answers your visitors from your pages, and cites them. If it does not know, it says so. It works with your own key at the AI provider of your choice, which bills you for the messages; we take nothing on top. It stays off until you switch it on.
Can my products appear in ChatGPT or Gemini?
Yes, with the Pro and Business plans: we prepare your catalogue in the format of ChatGPT, Google (Gemini, AI Mode, Copilot) and Meta, from your pages. You connect it once in each channel, and it stays up to date. The sale always happens on your site.
Do I need to touch my site’s code?
No. Two lines to paste in the <head> and, where the platform allows it, a redirect of /llms.txt. Nothing else in your pages changes, except the chat bubble if you switch it on.
Which platforms does it work on?
Shopify, Webflow, Wix, Squarespace, PrestaShop, WordPress, and any site where code can be added to the <head>. Each platform has its install page.
Do you change my prices or my content?
Never. We take what your public pages show, without rewriting or inventing anything, and read availability again on the product page at the moment an assistant asks. The chat states nothing your pages do not say.
What do you see of my visitors?
No cookie, no identifier, no profile. When an assistant queries your site, its search is kept as it arrives, with nothing that ties it to a person. For the chat, we never keep the text typed: only a summary without personal data and its theme, erased after 30 days.
How much does it cost?
A free tier to try it, then monthly plans according to the number of pages and sites. What assistants read and ask is never counted; only the chat has a daily message ceiling. The pricing page has the grid.
Can I stop anytime?
Yes. A subscription is cancelled from the profile, with no notice, and ends with the month already paid. Deleting the account purges your sites and their data at once.
Who is Plugster for?
Businesses and professionals: craftsmen, shops, practices, online stores, agencies, networks. We do not serve private individuals.
