Manual interviews deliver rich insight but cost $200-500 per session when accounting for recruiting, scheduling, conducting, transcribing, and analyzing. AI-moderated interviews change this equation: they deliver comparable qualitative depth at 10-20% of the cost and time.\n\n## The Scale Problem in User Research\n\n| Cost Component | Manual Interview | AI Interview |\n|---------------|-----------------|---------------|\n| Recruiting and scheduling | $50-100 per participant | Link sharing (no scheduling) |\n| Interviewer time | $100-200/hour | $0 (AI conducts) |\n| Transcription | $25-50 per session | Automatic |\n| Analysis per interview | 2-3 hours | Automatic (themes, quotes) |\n| Total cost per interview | $200-500 | $1-3 |\n| Total time per interview | 4-6 hours | 15-30 min (review only) |\n\n## When AI Interviews Match Human Interviewers\n\nAI interviewers perform well for:\n- **Structured research** with defined questions and probing paths\n- **Customer feedback** where respondents share experiences and opinions\n- **Discovery research** exploring problem spaces and behaviors\n- **High-volume qualitative** where you need 20-100+ conversations\n- **Consistent methodology** where every interview must follow the same framework\n\n## When You Still Need a Human\n\n- **Sensitive topics** requiring empathy and emotional intelligence\n- **Highly technical domains** where the interviewer needs subject matter expertise\n- **Executive interviews** where rapport and status dynamics matter\n- **Exploratory research** in completely uncharted territory\n- **Prototype testing** requiring screen sharing and real-time observation\n\n## How to Scale With AI Interviews\n\n### Step 1: Convert Your Interview Guide\nIf you have existing interview questions, convert them instantly:\n- Visit [koji.so/kojify](/kojify)\n- Paste your questions as text\n- Koji maps them to interview format with probing\n\n### Step 2: Configure Probing Depth\n- Set critical questions to 2-3 follow-ups\n- Set screening questions to 0-1 follow-ups\n- Add custom probing instructions for domain-specific topics\n\n### Step 3: Choose Text or Voice\n- **Text interviews:** Best for convenience, async responses\n- **Voice interviews:** Best for depth, natural conversation feel\n\n### Step 4: Distribute\n- Share the interview link via email, Slack, or embed\n- No scheduling needed -- respondents complete at their convenience\n- Set capacity limits to control sample size\n\n### Step 5: Analyze\n- Koji automatically generates per-interview summaries\n- Cross-interview theme analysis identifies patterns\n- Executive reports synthesize findings with supporting quotes\n\n## Getting Started\n\nThe fastest path from 0 to scaled research:\n1. Take an existing survey or interview guide\n2. Convert it at [koji.so/kojify](/kojify)\n3. Run 10-20 AI interviews as a pilot\n4. Compare depth and quality to your manual process\n5.
