Ghostwriter

Your AI teammate for building and improving agents.

Build

Empower your customer experience teams to build agents, whatever their technical expertise.

  • Prompts, not clicks

    Build or modify agents by describing how you want them to behave. Update workflows, systems integrations, guardrails, tone, and style with simple prompts.

  • Build from what you have

    Upload SOPs, raw transcripts, or even audio interviews of subject matter experts to create customer journeys from scratch.

  • Complete transparency

    See exactly what Ghostwriter built before anything goes live so you can review, approve, and ship with confidence.

Test

Guarantee agent quality at every stage of development.

  • Auto-generate simulations

    Proactively run tests with every build or update, so each change is validated before it reaches you.

  • Built for edge cases

    Identify and tests edge cases beyond the obvious scenarios, so your agent is ready for whatever customers throw at it.

  • Move failures forward

    Diagnose what went wrong and propose the next change for your team to review.

Improve

Proactively find and advance the next improvement, working alongside your team.

  • Find what deserves attention

    Monitor conversations, metrics, releases, and experiments, using your goals and guardrails to separate signal from noise.

  • Collaborative from signal to result

    Bring your team the evidence in Slack or Teams and a proposed next step, then follow the result after release.

  • Bring ideas, not just answers

    Build on customer context and your team’s feedback to uncover unmet needs and opportunities you may not have known to look for.
