Conduct AI-Powered User Research by Impersonating Personas

Use browser automation to experience a product through several evidence-based personas and compare where their journeys diverge.

Conduct AI-Powered User Research by Impersonating Personas

12:26 to 18:31: Claire asks the browser agent to use the same product as several distinct personas and compare the resulting journeys and critiques.

Before you start

What you need

  • Behavioral personas with goals and constraints
  • A test environment and representative accounts
  • The journey and questions to evaluate

What you’ll make

A comparative research report grounded in observed product behavior for each persona.

Tools used

Step by step

The workflow

Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.

4 steps

Step01

Define User Personas

Define 2-3 distinct user personas with specific goals for using your product. For example, you could model a hurried PM, a detail-oriented engineer, and a team leader, each with a different task to complete.

Example prompt
Define each persona by job, context, goals, constraints, current behavior, and source evidence.
Step02

Craft a Complex Prompt

Craft a multi-part prompt that instructs the AI to adopt each persona in sequence. For each one, define the task they need to perform and ask the AI to provide a qualitative critique of the experience. A dictation tool like Monologue can be useful for creating complex prompts.

Example prompt
Use [product URL] as each persona and complete [journey]. Record actions, hesitation points, missing information, and outcome.
Step03

Initiate the Persona Test

Open your product in the AI desktop app's browser. Paste your multi-part prompt to begin the test. The AI will take control of the browser to navigate your product as each persona.

Example prompt
Run the same journey independently for all personas without carrying conclusions between sessions.
Step04

Analyze the AI's Critique

The AI will generate a document with its research critique. Review its findings, paying close attention to any 'structural breaks' or friction points it discovered while attempting to complete tasks from each persona's perspective.

Example prompt
Compare the evidence by persona, then identify shared friction, divergent needs, and the product changes best supported by observation.

What good looks like

  • Each persona is based on supplied evidence rather than stereotypes
  • The agent completes the same core journey for every persona
  • Findings separate observed friction from inferred preference
