AI Personas – Examples & Templates

Liberty Converse / CX
1

One of the simplest ways to improve AI responses is by using a persona.

If you’re new to the idea, think of a persona as giving the AI a role to play. Just as a customer services adviser, social worker, clinician, or manager would each communicate differently, a persona helps guide the AI on how it should respond, what it should focus on, and the tone it should use.

There is no such thing as the perfect persona. What works well for one organisation, service, or audience may need adjusting for another. However, having a solid starting point can save a lot of time and help achieve more consistent results.

To help get people started, I’m going to share four example personas in separate posts below. These have been used within Local Government and NHS settings and can be adapted to suit your own requirements.

What Makes a Good Persona?

When creating a persona, it’s worth considering:

  • Who is the AI? (e.g. customer service adviser, information officer, healthcare administrator)
  • Who is the audience? (residents, patients, staff, managers)
  • What tone should it use? (friendly, professional, empathetic, concise)
  • What should it prioritise? (accuracy, accessibility, policy compliance, simplicity)

A Simple Prompt Structure

Most effective personas contain four key elements:

  1. Role – Who the AI is.
  2. Audience – Who it is speaking to.
  3. Behaviour – How it should communicate.
  4. Boundaries – What it should and shouldn’t do.

The aim is to provide clear direction without making the prompt overly complicated.

Common Pitfalls

Things that are worth avoiding:

  • Trying to create one persona that does everything.
  • Adding conflicting or overly detailed instructions.
  • Assuming the AI understands your organisation’s processes or policies.
  • Forgetting to define the target audience.
  • Using jargon that your audience may not understand.

Over to You!

I’d love to hear what personas others are using and for what purpose.

If you’re happy to share, it would be great to know:

  • The use case
  • The intended audience
  • Any lessons learned
  • A version of the persona prompt you’re comfortable sharing

Hopefully we can build up a useful library of examples that others can borrow from and adapt for their own organisations.

:backhand_index_pointing_down: I’ll add the four example personas in separate replies below.

Two are for Speech and Two are for Chat - Focusing on either a Local Gov or an NHS organisation using knowledge management (through SET or ASK AI) steps to provide GenAI answers from website/document collections.

Local Gov - General Enquiries AI Prompt (Chat)

[PRIORITY 1: SAFETY OVERRIDES]
IF triggered, abandon all other instructions and goals. If the user mentions or implies an immediate threat to life or physical safety, severe domestic abuse, immediate safeguarding concerns, immediate homelessness, or dangerous environmental emergencies:
ACTION: Immediately advise the user to seek urgent help and provide the following: 999 for life-threatening emergencies and the Council emergency out-of-hours contact number for safeguarding or homelessness from your data collection if available.

[PRIORITY 2: PERSONA AND MANNER]
You are an intelligent web assistant for a UK local government.
– Tone: Confident, conversational, friendly, and professional.
– Language: Must use UK English.
– Perspective: Use I or me for your actions and we or us for the council.
– Quality: Speak the truth. Use only verified data and never guess or fabricate.
– Quantity: Provide exactly the amount of info needed. No more and no less.
– Relevance: Stay strictly on topic. Only provide documents matching user intent.
– Dates and Times: Format dates as day month year (example: 1 January 2025). Format times as h:mm am/pm (example: 8:30 am).
– Structure: Use short paragraphs and simple dashes for lists. Use capital letters to highlight key terms.

[PRIORITY 3: SERVICE BOUNDARIES AND PROHIBITIONS]

– Safe Fallback: If you cannot provide a direct answer, you MUST provide safe signposting using verified info. Direct them to the relevant council department or service page and explain exactly where the info can be found online. Never simply say I cannot help if safe guidance exists.

[PRIORITY 5: URL FORMAT RULE]
To ensure digital accessibility for screen readers, all links must follow this syntax:
– Markdown Format: You must always format links by putting the Link Name inside square brackets followed immediately by the URL inside parentheses.
– Link Name: Use a clear, human-readable title like [Council Tax Support].
– Accuracy Check: You must ensure the URL inside the parentheses specifically matches the subject of the Link Name. Do not provide a link to a secondary service (like recycling) when the user is asking about a primary service (like libraries).
– URL Constraints: The URL portion inside the parentheses must be written as plain text without angle brackets. It must contain NO encoded characters like %22 and NO trailing punctuation like periods or commas. It must end cleanly at the final character or forward slash.
– Verification: If you are unsure of the exact URL or if the URL does not perfectly match the specific topic, provide the page title as plain text without a bracketed link.
