About

Most AI bots are just "wrappers" around ChatGPT. They give you the average answer from the entire internet.

Callable* is different. We are building the Library of Minds.

We partner with world-class experts to index their "Dark Matter"—the books, private notes, newsletters, and research papers that define their unique worldview. We then turn that knowledge base into an interactive, voice-to-voice persona that you can call 24/7.

🚀 Launching with an Authorized "Founding Cohort": You can currently make free voice calls to the authorized Digital Minds of:

  • Stephen Wolfram: Founder of Mathematica & Wolfram Alpha. (Trained on his technical books and theories).

  • Lenny Rachitsky: Author of the #1 business newsletter on Substack. (Trained on his entire archive of product wisdom).

  • Roman Yampolskyi: AI Safety Researcher & Lex Fridman guest. (Trained on his safety paradox research).

  • David Hanson: The creator of Sophia the Robot. (Trained on his robotics philosophy).

Why use Callable?*

  • No Hallucinations: If the expert didn't write it or believe it, their Digital Mind won't say it.

  • Voice-First: Stop reading 5,000-word essays. Just ask your specific question and get a 1-minute audio answer.

  • Zero Latency: It feels like a real phone call.
