Steno AI

Steno.ai builds AI "Twins" — voice and chat-based agents that clone a real person's voice, tone, and expertise so they can hold one-on-one conversations with an audience at scale. Creators upload a few minutes of audio and complete an interview describing how they think and speak; the Steno Twin Engine uses that to produce a voice clone and a personality model, which the site says works across 23+ languages even when trained only on English audio. The product is aimed at experts, coaches, and influencers who want to answer audience questions without doing it live every time, and at brands that want a branded conversational agent. A dashboard lets owners fine-tune personality and set guardrails so the Twin stays on-brand, and Twins can be deployed to websites, apps, and other channels through an SDK. The company also publishes developer documentation, suggesting technical teams can integrate a Twin beyond the hosted dashboard. Pricing starts at $500 per month for a Starter tier with one Twin and a monthly credit allowance, putting it out of reach for casual users and squarely aimed at professional creators and companies with an existing audience. The site names public figures like Tony Robbins and Peter Diamandis as users, but doesn't offer independent verification of voice-clone accuracy beyond its own marketing claims.
