Prompt optimizer for Conversations AI: test, tune, and launch better chat agents

What changed

If you have set up a Conversations AI agent, you can now see how it will behave in real customer chats before you turn it loose on your live traffic. EveryCatch now lets Prompt Optimizer work directly with Conversations AI, so you can validate and improve your agent with confidence before customers interact with it.

Prompt Optimizer creates realistic customer scenarios, runs full chat conversations against a cloned version of your agent, evaluates what happened, highlights where the agent fell short, and then suggests an updated prompt designed to perform better. Your live agent configuration stays unchanged until you decide to review the changes and apply the improved prompt yourself.

How it works

1. Configure - build your test plan

• Auto-generated scenarios: The AI creates contextual test scenarios from your agent’s prompt, language, knowledge base, appointment configuration, and actions. Each scenario includes a customer persona, an opening message, expected behaviors, and a priority level so you can focus on what matters most.
• Reuse past scenarios: You can load and reuse scenarios from earlier test runs instead of recreating them each time.
• Multi-language support: Scenarios, evaluations, and optimized prompts all follow the language your agent is configured to use, so you can test in the same language your customers see.
• Usage visibility: You can see how many free daily messages you have used and how many are left, along with a pre-run checklist so everything is ready before you start testing.

1. Test - real chats, real actions

• Real conversations, not simulations: Prompt Optimizer sends natural, customer-style messages to your cloned agent and waits for its real responses, so the test behaves like an actual conversation.
• Action tracking: You can see when the agent triggers Appointment Booking, Human Handover, Workflow Triggers, Bot Transfer, Stop Bot, Auto Follow-up, Contact Field Updates, and Knowledge Base Queries during each conversation.
• Full transcripts with AI scoring: Every chat comes with a full transcript and an AI evaluation that checks the outcome against expectations and explains what passed, what failed, and why.
• Runs in the background: You can leave the page while tests run and return later to view the completed results.

1. Improve - AI-guided prompt optimization

• One-click Improvise: With a single click, the AI reviews failed chats, identifies the root causes, generates an updated prompt, and tests it against your scenarios.
• Auto Optimize: You can let Prompt Optimizer run several optimization attempts automatically until your target accuracy level is reached.
• Prompt diff viewer: Before you apply any update, you can compare the new prompt against the current one and see exactly what text has changed.
• Best Variation tag: The most accurate prompt version is clearly marked as the best variation, and you can review the full history of every optimization attempt.

Safe by design

• All testing runs against a cloned agent, so your live Conversations AI agent stays unchanged until you click “Use Prompt” to apply an update.
• Temporary test contacts are created for each run and then removed automatically, which keeps your CRM clean from test-only data.

Good to know

• AI evaluations can vary slightly between runs, so use the accuracy scores as directional guidance rather than an exact measure.
• Real actions such as bookings, workflows, and human handovers do execute during testing. Where possible, connect your agent to test calendars, test pipelines, and test workflows before you run optimization.
• Long or stuck test conversations are automatically timed out so that every run can finish and return results.
