How to Write an Effective AI PRD: Checklist for AI Product Managers

In traditional internet product development, a PRD ensures predictable behavior by detailing processes, use cases, and interfaces. However, in the AI era, the inherent uncertainty of models makes this approach ineffective. Product managers must shift from "locking processes" to "defining frameworks": specifying behaviors that must be stable, areas allowing flexibility, and evaluation criteria. Delegate execution to the model while retaining control over decisions and error-handling to ensure the PRD's guidance and reliability.
Avoiding the "Intelligent" Trap: Practical Implementation of Embedded AI
Embedded AI (such as smart summaries or automatic recommendations) is a common starting point, but many PMs use vague terms like "intelligent generation" or "automatic optimization," leading to team confusion and patchwork fixes during development. To avoid this, break down tasks into highly specific steps: instead of "help users understand content," specify "extract core themes from input text, generate 2-3 bullet point key points + a summary no longer than 50 words."
Next, scrutinize data like an editor: in the PRD, list the fields, context, and historical records fed to the model, and evaluate their reliability and structure. Crucially, predefined "risk preferences" for users—when data is insufficient, opt for a conservative output like "unable to generate" or an aggressive one like "based on limited data, for reference only." This determines product usability and user trust.
Case: A short-video platform's "smart clip summary" feature initially produced irrelevant content, prompting user complaints about "off-topic summaries." The team redefined the task in the PRD as: "Extract core events from the first 30% of the video, generate a title no longer than 15 words + 3 bullet points, each with corresponding video timestamps." The fallback strategy: if confidence is below 0.7, return "Unable to generate high-quality summary; suggest watching the original video." After launch, summary satisfaction rose from 61% to 87%, and average playtime increased by 9% as users trusted the system more.
From Drawing Processes to "Training People": Rethinking Agent-Type AI
Agent-type AI (like chatbots or smart assistants) is more complex—don't rush into system architecture diagrams. First, consider its role in the business. The PRD should act like an "employee onboarding manual," clearly defining authority boundaries: which issues must be directly answered, which only suggested, which require human review, and which principles to prioritize in gray areas.
Avoid technical jargon like "long-short term memory"; use business language to define what it can "see" and "remember" for how long. For example, can it reference a user's return record from a year ago? These decisions directly impact privacy risks and user trust. Only when permissions, obligations, and paths are clearly documented will the agent's behavior remain consistent across model updates.
Case: An e-commerce AI customer service agent initially had "unlimited memory" access, leading it to say during a new order query, "Your return last year was due to oversized fit; I'll recommend a larger size this time," resulting in complaints and a 31% negative feedback rate. The team redefined: access only recent 90-day records; require user consent for historical references (e.g., "Do you need me to refer to your previous return records?"); prohibit mentioning sensitive info without authorization.
Redefining "Qualified": Systematic Evaluation and User Experience
Refer to my previous share on "AI Product Evaluation Framework" In AI products, the evaluation section goes beyond simple "pass/fail" because experiences often fall between "slightly better" and "slightly worse." You must use evaluation sets (Golden Sets) and quantitative metrics to measure overall performance. For instance, in designing an AI customer service, specify in the PRD: expect the first version's first-query resolution rate to match a certain percentage of human levels, with negative feedback not exceeding a threshold, and explain the rationale.
To enable continuous AI evolution, the PRD must include a closed-loop UX feedback system. Beyond explicit feedback like likes, track implicit behaviors such as adoption rates or secondary edit rates. These data points are not just metrics but key fuel for subsequent model fine-tuning.

In the AI product era, many PMs have tried using LLMs to write PRDs. But competent PMs treat models as "brainstorming tools"—first think through problem definitions, boundary settings, and evaluation standards yourself, then use them for polishing. AI product success often hinges on edge cases: extreme users, gray scenarios, data gaps. These are your real battlegrounds.
