ConvApparel
A human-AI conversation dataset and evaluation framework aimed at closing the realism gap in LLM user simulators. Useful for PMs building agents and conversational products that need better simulation and evaluation.
Key Highlights
- ConvApparel is a Google Research dataset and evaluation framework focused on measuring realism in LLM-based user simulators.
- It helps teams identify when simulated users diverge from real conversational behavior, reducing false confidence in offline testing.
- AI PMs can use its approach to improve agent evaluation, simulator design, and launch readiness for conversational products.
- The project is especially relevant for teams building assistants, support bots, and other products that depend on synthetic interaction testing.
Overview
ConvApparel is a human-AI conversation dataset and evaluation framework from Google Research designed to measure and reduce the “realism gap” in LLM-based user simulators. In practice, it helps teams compare simulated users against real human conversational behavior, making it easier to understand where synthetic interactions are too clean, too predictable, or otherwise unlike production usage.
For AI Product Managers, ConvApparel matters because many agent and conversational product decisions depend on offline testing, synthetic data generation, and simulator-based evaluation. If user simulators are unrealistic, teams can overestimate agent quality, miss failure modes, and ship products that perform well in test environments but poorly with real users. ConvApparel is useful as both a dataset and a framework for improving evaluation rigor when building assistants, support bots, and other conversation-driven products.
Key Developments
- 2026-04-10 — Google Research introduced ConvApparel as a human-AI conversation dataset paired with an evaluation framework to quantify and bridge the realism gap in LLM-based user simulators.

Relevance to AI PMs
- Improve offline evaluation quality: PMs can use ideas from ConvApparel to pressure-test whether simulator-based benchmarks actually reflect real user behavior before relying on them for launch decisions.
- Design better user simulators: Teams building agents, copilots, or support workflows can use ConvApparel-style datasets and realism metrics to make synthetic users less scripted and more representative of edge cases.
- Reduce product risk in conversational launches: By identifying gaps between simulated and real conversations, PMs can prioritize testing, guardrails, and iteration on the scenarios most likely to fail in production.
