Your site's system prompt: train ChatGPT to describe your clinic correctly
Published on October 07, 2026

Can you train ChatGPT to describe your clinic correctly? Yes, in part: a public system prompt on your site, like the llms.txt file, gives explicit instructions that AI models consider when interpreting and summarizing your pages. It's not total control, but it's the most direct way to tell AI who you are.
At Bincoo, while monitoring thousands of clinics, we noticed that models repeat description errors when a site declares no information about itself. Those who declare, err less.
More than 10,000 companies already use Bincoo to be recommended by ChatGPT, Gemini, and other platforms.
What it is and why it works
Every AI model that visits your site tries to summarize what it's about. Without instructions, it improvises based on loose fragments: an old title, generic copy, mismatched mentions. With explicit instructions, it gets a script.
The llms.txt file is the standardized way to publish that script: a simple text at the domain root listing what the site is, whom it serves, and where. Search bots and AI crawlers already look for this file by convention.
What your system prompt needs to contain
- Official name and main specialties, with no ambiguous abbreviations;
- Cities and neighborhoods served, the model needs to link you to the region;
- Services in detail, implants, orthodontics, aesthetics, with the name a patient would use;
- Verifiable differentiators, technology, team, conveniences;
- What the clinic does not do, so the AI doesn't recommend you for the wrong treatment;
- Official channels, site, phone, and correct profiles so it doesn't cite outdated data.
Example structure
| Block | Content | Why it matters |
|---|---|---|
| Identity | Name, legal name, specialties | Resolves name ambiguity |
| Location | City, neighborhood, addresses | Ties the clinic to local queries |
| Services | List with short description | Basis for treatment-based recommendations |
| Team | Names and professional registrations | Verifiable authority |
| Policies | What is not done, limits | Prevents improper citations |
| Contact | Official channels | Blocks outdated data |
Mistakes that cancel the effect
- Declaring one thing and publishing another: if the prompt says 'implant specialists' and the site has no implant page, the model ignores the instruction;
- Empty promotional copy: instructions need to be factual, not slogans;
- Publish and forget: if the address or team changed, the file needs to change too;
- Only the file, no content: llms.txt guides, but the pages are the proof. The two work together;
- Copying a competitor: models detect repeated patterns and devalue them.
The full cycle: declare, publish, and monitor
The system prompt is one piece, not the whole game. The sequence that works in the clinics we track:
- Structure pages per service with real content;
- Publish the instructions file on the domain;
- Standardize name and data across directories and social networks;
- Monitor weekly how the AIs started describing you;
- Adjust what the AI still gets wrong.
Bincoo delivers this cycle ready-made: it generates your clinic's system prompt, the optimized articles, and the weekly report showing how each AI describes you today. With the Essential plan, at R$ 39.00/month, everything is already included.
Conclusion
- A public system prompt guides models to describe your clinic correctly, as long as it's backed by consistent pages;
- Declare identity, services, region, and limits in factual language and keep it updated;
- Measure the effect in monitoring, because AI only improves what you can see.

Frequently asked questions
"What is a system prompt on a clinic's website?"
It is a public block of text, usually in a dedicated file, that guides bots and AI models on how to interpret and describe your site. It works as a permanent instruction for whoever reads the page automatically.
"Does a system prompt guarantee ChatGPT will describe me correctly?"
It doesn't guarantee it, but it influences it. Models give weight to explicit instructions from the site itself, especially when combined with consistent content across pages. On its own, it does not override contradictory mentions on the web.
"Where do I put my site's system prompt?"
In the text file publicly accessible at the domain root, the llms.txt, and reinforced in the page structure. The idea is that any bot visiting the site finds the instructions effortlessly.
"What should I write in that prompt?"
Official name, specialties, cities served, verifiable differentiators, the audience you serve, and what the clinic does not do. Direct language, in bullet points, with no promises the site content can't back up.
"Do I need a developer to implement it?"
To publish the file, yes — it's a simple technical step anyone who manages your site can do in minutes. For the strategic content, Bincoo generates the prompt along with the optimized articles, starting with the Essential plan at R$ 39.00/month.
