The new feature delivers fully scripted, natural-sounding conversations between multiple AI voices—ideal for ad agencies, internal comms, training teams, and creative studios.
LONDON, UK – June 3, 2025 – Wondercraft, the AI Audio Studio, today announces the launch of Convo Mode, a major expansion to its platform that enables users to write and produce fluid, lifelike conversations between multiple AI voices—no microphones, no actors, no stitching required.
Built on the same speech synthesis pipeline used to power the popular NotebookLM podcast, Convo Mode now gives full creative control to users across industries: from agencies producing client work to L&D teams building training modules, to marketers scripting brand content and podcast producers developing multi-voice episodes.
“Convo Mode is the Turing moment for AI-generated dialogue. Realistic text-to-speech has been achieved for over a year now, but emulating conversations always stumbled into the uncanny valley—until now.” says Dimi Nikolaou, Wondercraft co-Founder.
Convo Mode lets users write a script like a screenplay, assign voices to different parts, and generate a full conversation with realistic pacing, tone, and emotion. The result is a multi-speaker audio file that feels spontaneous and human—but is fully editable at any stage.

In the sample above, all dialogue was a 1-shot generation, using Convo Mode on Wondercraft.
Unlike typical text-to-speech tools that render one voice at a time, Wondercraft’s Convo Mode processes the entire scene holistically—so voices react in context, and the rhythm of conversation feels natural and cohesive.
Audio Overviews by NotebookLM amazed everyone with their natural conversational rhythm—but they had one drawback: you couldn’t take them much further. Wondercraft, built on the same Gemini-based speech synthesis pipeline, fixes that with Convo Mode, giving you three game-changing benefits:
Perfectly expressive, podcast-style conversations—now with every detail in your hands.
