The Build Experience

It's even easier to build an agent now

Taking too long to build an agent from scratch?

No problem. Launching Teacher AI. Let our AI build it for you.

  1. Tough to build a nuanced agent? Not anymore

    Describe the agent in your own words

    Tell Teacher AI who to call, what to say, and what counts as success, in plain language. You don't need prompt engineering or flowcharts. One sentence is enough to start.

  2. Agents breaking on the questions nobody thought to ask?

    Answer a few clarifying questions

    Teacher AI asks about what's missing: languages, objections, qualifying criteria, and handoffs. Each answer tightens the agent before it ever makes a call.

  3. Stitching voice, language and tools together takes time?

    Watch it build in seconds

    The prompt, voice, language mix, and tools come together live, with a readiness score as it goes. You get a deployment-ready agent, not a draft to finish.

  4. One prompt tweak quietly breaks a live agent?

    Review the prompt diff, then accept

    See exactly what changed, with recommended settings for latency, voice, and turn-taking. Nothing is saved until you approve it.

  5. Every small change starting the build over?

    Keep refining by chat

    Ask Teacher AI to change the tone, add a language, or handle a new objection on an existing agent. It updates the same way, with a diff to review.

  6. That’s it. Your agent is ready for its first call.

Automated call screening leading to connectivity issues?

Solved!
