How to Customise an AI Model So It Actually Works for Your Business
Hook: You’ve just paid for an AI subscription that promises to save hours each week. Yet when you ask it about your company’s latest policy or your industry’s jargon, it gives you a blank stare—or worse, a made-up answer. What if you could shape that AI into something that speaks your business’s language?
Start with a clear goal
Before you touch any settings, ask yourself: What one task do I want this AI to do better than a generic version? Pick something specific. For example:
- summarise your weekly team reports in 3 bullet points
- draft emails that match your company’s tone
- extract key dates from contracts automatically
Write that goal down. Every customisation step from here will ladder up to it.
Give the AI your documents to read
Most AI models are trained on public data. They don’t know your internal style guide, product names, or compliance rules. Fix that by uploading your key files.
- Gather the documents you want the AI to learn from (SOPs, brand guides, past customer emails, product specs).
- Convert them to plain text or PDF. Avoid scanned images—AI can’t read those yet.
- Upload them to the platform’s “knowledge” or “memory” section. In ChatGPT, it’s called “Custom Instructions” or “My Files.” In other tools, look for “RAG” (retrieval-augmented generation) settings.
Tip: Start with three to five core documents. Too many files can confuse the AI.
Teach the AI your language
Every industry has its own acronyms and shortcuts. Teach the AI to use them correctly.
- Create a short “glossary” file with terms like “PO” (purchase order), “NPS” (net promoter score), or your product’s internal code names.
- Add a few example sentences that show how your team uses these terms in real messages.
- Upload the glossary as a separate file or paste it into the “custom instructions” box.
The AI will now mirror your terminology instead of guessing.
Set guardrails so it stays on-brand
Even a well-trained AI can go off-script. Prevent that by adding rules.
- In the AI’s settings, look for “response style” or “tone of voice.” Select “professional,” “concise,” or “friendly” to match your brand.
- Add a short style guide snippet: “Use active voice. Avoid jargon unless the user asks. Never mention competitors.”
- For sensitive topics (pricing, legal clauses), add a disclaimer: “If unsure, say ‘I don’t have that information—please contact [team].’”
Test the AI by asking it to draft a reply to a customer complaint. Does it sound like your team? Adjust the style guide until it does.
Wrap-up
Customising an AI isn’t about turning it into a robot clone of your team. It’s about giving it enough of your context to handle the 80% of routine tasks that slow everyone down. Pick one goal, feed it your documents, teach it your language, and set gentle guardrails. In a few hours, you’ll have an assistant that actually understands your business—not just the internet. Try it today: open your AI tool, upload one file, and ask it to summarise a recent memo in your company’s tone.
