Steno.ai is a platform for creating AI Twins — hyper-realistic digital versions of a person or brand that can hold one-on-one conversations with audiences at infinite scale. Built for experts, coaches, influencers, and brands, it transforms the traditional one-to-many content model into direct, personal relationships between creators and their followers through text, voice, and video interactions.

The process starts with a structured interview that shapes how the Twin thinks, speaks, and responds. Steno's team fine-tunes and trains the model on the creator's voice, style, and expertise until the Twin accurately reflects its subject. Voice cloning is included — creators simply upload a few minutes of audio to their dashboard and the Steno Twin Engine generates a realistic voice model instantly.

Once live, an AI Twin operates continuously across any channel. It can be deployed on a creator's website, inside a mobile app, or through any screen via the Steno SDK. The platform supports monetization, allowing brands to structure free trial access, upsell to paid subscriptions, and track engagement. A credit-based system powers all interactions, including text messages, real-time voice calls, and video calls.

Plans are available at four tiers — Starter, Growth, Scale, and Enterprise — with monthly or annual billing. Add-ons such as iOS and Android mobile apps and Pro Voice are available separately. The platform includes a dashboard where creators have full creative control over their Twin's personality and behavior. Data and trained models are kept strictly separate per customer, with full intellectual property ownership retained by the creator.
