Despite emerging scholarship on applying generative AI (GenAI) in qualitative data analysis, this new area remains underdeveloped. This presentation proposes a Guided AI Thematic Analysis (GAITA), an adapted version of King et al.’s (2018) Template Analysis to help qualitative researchers apply Generative AI in thematic analysis process. Based on the PERFECT procedure, this framework positions researchers as a reflexive instrument and intellectual leader while thoroughly guiding GPT-4 in four stages: data familiarization; preliminary coding; template formation and finalization; and theme development. Additionally, I propose the ACTOR framework, a simple approach to combining different effective prompting techniques when working with GenAI for qualitative research purposes.
