Steno

Steno is a platform for building "AI Twins" — conversational AI agents modelled on a real person's voice, expertise and perspective. Rather than training a bot on generic documents, Steno's approach is centred on the individual: an interview process captures how that person thinks, speaks and responds, and the resulting Twin answers questions and guides conversations in their familiar style.

The service targets people whose personal brand is the product: experts, coaches, influencers and brands. Publicly, Steno has highlighted twins built for figures such as Tony Robbins and Peter Diamandis, and the site frames the offering around the idea of scaling authentic relationships — being present everywhere at once without being stretched thin. That positioning appeals to anyone whose audience keeps asking the same questions across DMs, communities and support channels.

Steno positions itself as a managed, done-with-you service rather than a self-serve tool. The process moves from design interview to training and fine-tuning to deployment across the channels that matter, after which the Twin runs continuously. Pricing is not published on the site and is arranged through a demo conversation, so interested parties should contact the team for scope and cost.
