How I Turn User Interview Transcripts into a PRD Using AI
A practical workflow for going from raw research to a structured product requirements doc, without losing your design judgment along the way.
User research synthesis is slow. You do 8 interviews, get 8 transcripts, spend two days on sticky notes, and another day writing it all into something a PM can read. Most of that time isn't thinking. It's just reading and moving text around. Claude handles that part now.
What You Need
- Interview transcripts (Otter.ai, Rev, or just manual notes work fine)
- Claude Pro (the context window matters for long transcripts)
- Somewhere to write the final PRD: Notion, Google Docs, whatever you use
Step 1 — Get Your Transcripts Clean Enough
You don't need perfect transcripts. Auto-generated ones from Otter or Fireflies work. Just do a quick pass to fix names and remove filler words. 10 minutes per transcript is enough.
Step 2 — Pull Themes Out of the Transcripts
Paste one transcript at a time and ask Claude to extract the signal:
Here is a user interview transcript. Extract:
- The top 3-5 pain points the user mentioned
- Any workarounds they described
- Direct quotes that capture frustration or confusion
- Features or changes they asked for explicitly
Keep each point to one sentence. Flag anything that seemed emotionally charged.

Step 3 — Find Patterns Across All Interviews
Once you have all the extracted points, paste them together and ask Claude to find the common threads:
Below are pain points and quotes from 8 user interviews about [product/feature].
Group them into recurring themes. For each theme:
- Give it a short name
- Write one sentence describing the problem
- List which users mentioned it (by number if names aren't included)
- Pull the strongest quote that represents the theme

Step 4 — Turn Themes into User Needs
Themes tell you what people complained about. User needs tell you what they actually require. Ask Claude to reframe:
Here are the research themes from our interviews:
[paste themes]
Rewrite each one as a job-to-be-done statement:
"When [situation], I want to [motivation], so I can [outcome]."
Then rate each need as High / Medium / Low based on how many users mentioned it and how emotional their language was.Step 5 — Draft the PRD Structure
Now give Claude everything it needs to write a first draft:
You're a senior product designer. Based on the user needs below, write a PRD outline with these sections:
1. Problem statement (2-3 sentences)
2. User needs (from the research, formatted as a table: Need / Priority / Evidence)
3. Success metrics (3-4 measurable outcomes)
4. Scope: what's in, what's out
5. Open questions that need stakeholder input
User needs:

Keep it concise. This is a working draft, not a final doc.
Step 6 — You Fill In the Judgment Calls
This is the step Claude cannot do for you. Go through the draft and add:
- Business context and constraints Claude doesn't know about
- Priority decisions based on your team's current goals
- Technical feasibility notes from conversations with your dev team
- Anything politically sensitive that shouldn't live in a shared doc as-is
What This Actually Saves
Before this workflow, a full research-to-PRD cycle took me 3 to 4 days. Extract themes from transcripts, run an affinity mapping session, write up insights, draft the requirements doc, review and clean it up. All manual.
Now steps 2 through 5 take about 2 hours. Step 6 takes another hour. The research and interviews still happen in person. The thinking still happens with my brain. The text-moving part is gone.
What AI Gets Wrong
- It misses tone. A user saying something reluctantly reads differently than saying it confidently. Claude can't feel that
- It over-surfaces explicit requests. Users saying 'I want X' gets weighted higher than body language or workarounds, which often reveal more
- It doesn't know your product history. Claude has no idea what you already tried and why it failed
Quick Summary
- Get transcripts cleaned up (10 min each)
- Extract pain points and quotes per transcript (2 min each with Claude)
- Group into themes across all interviews (3 min)
- Reframe themes as job-to-be-done user needs
- Ask Claude to draft the PRD structure from those needs
- Add your judgment, business context, and priorities to the draft
The research still needs a real human in the room. But everything after the interviews can be cut from days to hours.
