A **Smart Event** is any product **or** user behaviour you want to track—clicks, page states, errors, banners, onboarding steps, you name it. Think of it as flexible, AI-driven analytics you configure **without code changes** or manual work. ## How Smart Events Work Decipher’s AI watches every user session replay. Each time the page changes *or* the user does something, the AI checks whether that moment matches any Smart Event definitions you created. When it does, it tags the replay with the event—retroactively and going forward. ## What Can You Do With Them? * **Quantify** how many users triggered an event and spot trends over time. * **Jump straight into replays** for people who met—or missed—an event. * **Drop events into Funnels** to see exactly *where* and *why* users drop off. ## Examples * User clicked **Submit** and saw an **error banner** * User **visited** the dashboard page * A notification appeared: *“No more tokens”* * User **completed** the **third onboarding task** Imagine you’re asking an intern to tag replays—spell things out. * Mention **where** on the page a button lives (e.g., *“blue **Save** button in the top-right corner”*) * Include **exact text** that might appear on a banner or dialog Define **lots** of Smart Events — cover key activation steps, new-feature usage, and common issues. Smart Events + Funnels surface high-impact insights in minutes. *** *Doc v2025-05-16 Rev 1*
