Building and refining AI voice agents can be tricky. Every word, phrase, and branch of logic impacts your agents’ performance and, in turn, your customers’ experience.

Until now, adjusting these prompts meant requesting managed updates from our team, which guaranteed effective optimization but slowed down testing and iteration.

Many of our customers wanted direct control, without worrying about breaking agents or investing in changes that didn’t improve business outcomes.

That’s where our all-new telli Prompt Editor comes in.

Check out our launch video for a quick look inside the new Prompt Editor.

Meet the telli Prompt Editor

This user-friendly tool empowers you to refine conversation design and instantly test changes, accelerating the path to higher-performing agents.

With the Editor, you can:

• Define complex conversation rules with guardrails in place
• Receive AI-generated suggestions for tone, flow, and clarity
• Edit prompts manually through an intuitive, structured rich text editor
• Review and approve changes on your terms (either individually or all at once)

The Prompt Editor gives you full control over your scripts, while providing real-time, AI-powered guidance to ensure every update actually improves performance. This powerful combination of automation and human oversight reduces the optimization cycle from days to minutes.

Your built-in, AI-powered conversation coach

The core innovation of the Prompt Editor is a conversational AI assistant that partners with you on your edits.

This could include:

• Asking it to make an agent friendlier and more engaging
• Instructing it to shorten a section of the script for conciseness
• Requesting complete flow updates, such as disqualifying irrelevant leads and politely wrapping up the call

The AI assistant suggests language tweaks and flow adjustments based on its observed best practices, so you never have to guess at how to phrase something or where to place a prompt.

Maximize your performance

Success means something different for every team, and the Prompt Editor helps you adapt your agents to meet those unique goals. Some teams aim for higher conversion rates and smoother human handoffs, while others seek improved data capture and enhanced customer qualification.

Whatever your goal, telli’s AI assistant instantly shows you how to realize it by providing the tools to adjust flow, messaging, and logic on the fly.

How it works

The optimization workflow is easy and intuitive, so you can start making edits and improving agent performance in a matter of minutes:

1. Log into the telli dashboard, and click “Agents” followed by “System Prompt”
2. Enter your editing request (as informally phrased as you’d like) into the chat
3. Receive guidance from the Prompt Editor on better conversation flow, correct question placement, and optimized language for tone, clarity, and conciseness
4. Review all suggestions, and accept or reject the changes (either individually or all at once)
5. Optional: Make any additional manual changes in the rich text editor, such as inputting variables (like a customer name placeholder) and tools (like a calendar for scheduling)

‍

Rapid iteration with better results

The faster you iterate, the faster you boost appointment bookings, improve call transfers, and build customer trust. It’s that simple.

The Prompt Editor enables you to iterate as quickly as your business needs evolve. Whether that means testing a new sales objection handler, updating a compliance disclaimer, or reworking an agent’s rapport-building strategy, you have the power to do so whenever you want.

‍

Manual control when you need it

AI suggestions streamline your workflow, but sometimes you know exactly how to fine-tune.

Unlike a raw LLM editing environment, our rich text editor provides a clear and structured view of the prompt, making it easy to modify individual words or adjust the script’s logic.

With this transparency, you’re always in control. No prompt engineering expertise required.
