A prompting technique where, before asking an LLM to summarize or analyze something, you explicitly assign it a role or persona — e.g., 'you are a product manager at Glean' — rather than issuing a generic instruction. Framing the request from a specific perspective narrows the model's implicit criteria for what's relevant, producing more targeted output than an unframed prompt. Cited by Tamar Yehoshua (Glean) for tasks like summarizing competitor news or comparing PR angles. Complements AI-Assisted Competitive-Analysis Research and Chat PRD (Templatized AI PRD Tool) as a lightweight technique for getting structure out of general-purpose chat models.
