A step-by-step way to work
Transcribe and make it queryable
Use transcription so you can later ask 'where did people mention pricing?' across all sessions — you analyse instead of typing.
Cluster across interviews
Ask AI to find themes spanning multiple sessions, with mention counts, then verify each against the raw quotes.
Hunt for disconfirming evidence
Ask 'what did people say that contradicts the emerging theme?' — AI is useful for finding the counter-examples you're motivated to ignore.
Critique your technique
Paste a transcript and ask where you led the witness, asked a closed question, or missed an obvious follow-up.
Keep quotes sacred
Never accept a 'cleaned up' quote. The exact words are the data.
Real prompts, and what good output looks like
My emerging theme is 'users find the reporting feature too complex.' Across these 6 transcripts [pasted], what evidence contradicts that theme?
2 of 6 actively praised the depth of reporting ('I switched from a competitor because their reports were too basic').
1 said complexity wasn't the issue — discoverability was ('once someone showed me, it was fine').
So the theme may be too broad: the friction could be 'hard to discover' rather than 'too complex', and a power-user segment values the depth. Worth segmenting before concluding.
Review this transcript excerpt and tell me where I, the interviewer, made mistakes [excerpt pasted].
You asked 'so the slow load time was annoying, right?' — leading; it suggested the answer. Better: 'how did the load time affect what you were doing?'
When they said 'it was fine I guess', you moved on — a missed follow-up. A simple 'tell me more about 'I guess'' might have surfaced a real reservation.
Otherwise your open-ended openers were strong.
A prompt you can reuse
Fill in the highlighted parts and paste it into your AI tool of choice. Edit the output — it's a starting point, not a finished answer.
Help me synthesise advanced discovery interviews. Treat clusters as drafts to verify, and never alter a quote. Transcripts / observations from [N] interviews: [paste] Please: 1. Cluster observations into themes that span multiple interviews; label each and give mention counts. 2. Explicitly list evidence that CONTRADICTS each emerging theme. 3. Flag any theme supported by only one participant. 4. Suggest where I should segment rather than generalise. Keep all quotes verbatim.
What AI gets wrong here
Confirmation bias, amplified
If you prompt toward your hoped-for theme, AI will helpfully find support for it.
Tidied quotes
Summarising can silently reword what participants said.
Premature generalisation
AI will state a theme as universal when it's really one segment's view.
Synthesis is the heart of discovery, and it's where a confident AI summary can do the most damage — merging distinct issues, smoothing over contradictions, generalising from a couple of voices. AI earns its place by transcribing, counting, and surfacing counter-evidence faster than you can. The insight — deciding what the research actually means — comes from your own reading of the words people really said.
