The 20 people you can chat with, and how we compiled them

Timbre’s library now holds 20 people. Each profile is compiled from public recordings of the person speaking: podcasts, interviews, talks, lectures and Q&A. Together that is about 1,300 hours across more than 1,500 recordings, split into more than 80,000 timestamped passages. Here is who is in the library, how we built each profile, and how to start a conversation.

Who is in the library

We chose the 20 profiles with the deepest public record we had already indexed, measured in hours of recordings where the person is speaking. Depth matters because an answer can only cite what the recordings cover. A profile built from hundreds of hours can follow a question further than one built from a single interview. We also left out profiles where the collected recordings mixed up different people who share a name.

The list is ordered by hours of recordings as of October 29, 2026, and the numbers grow as new appearances are added. The suggested questions are editorial starting points, not promises that the recordings answer every one.

How we compiled each profile

Compiling starts with discovery. Timbre searches for the person’s public talks, podcasts, interviews, lectures and Q&A, then ranks what it finds before downloading anything. Recordings from the person’s own channel and official sources come first, followed by media appearances. Edited compilations are held back, and each channel has a cap on how much of a profile it can supply, so a profile reflects many conversations rather than one outlet’s selection.

Each recording’s transcript is read with its timestamps. Transcripts are fingerprinted, so a re-upload of something already indexed is skipped, or replaces the earlier copy when it is the full episode or the better upload. A speaker check then confirms the person is actually the one speaking. Recordings where they are not, such as commentary about them, are set aside.

We are also labelling every line of each transcript by speaker: the person, someone else, or unclear. Passages are then cut so none spans two speakers. Once a recording is labelled, search reads only the person’s own turns, so an interviewer’s question is never cited as their answer, and an answer uses the year a recording was made, when it is known, rather than its upload date. Labelling has started, and several profiles are already fully labelled.

Every passage keeps its original timestamps. When you ask a question, Timbre retrieves the relevant passages and cites them, so you can open the recording at the moment an answer draws on. Recurring reasoning patterns are kept only when several separate recordings support them.

Profiles keep growing. Each one is checked about once a day for new public appearances, which go through the same checks before they are added.

How a conversation works

Choose a person from the library and ask about a decision, idea or problem you are working on. You talk with a clearly labelled AI simulation grounded in that person’s recordings. Answers separate what is documented, under From the record with citations, from reasoning applied to your situation, under Applied to you.

Ask follow-ups, push back on a point, or open a citation to hear the passage in context. You can also bring several people into one group chat and compare their perspectives on the same question. A few ways to start:

  • 01Ask the Alex Hormozi simulation what to check before raising your prices, then open the recordings it cites.
  • 02Put Jamie Dimon, Jane Fraser and Brian Moynihan in one group chat and compare how each frames risk.
  • 03Ask Jensen Huang and Lisa Su how they would explain a long technical bet to a team.
  • 04Ask the Steve Jobs simulation which features to cut, then check the year of each recording it cites.

How much of each archive you can use

Every plan can talk with all 20 people. What changes is how much of each archive a conversation draws on. The free Listener plan uses the newest 6 hours of recordings per profile, Studio the newest 24 hours, and Roster the full verified archive. For someone with a long public record, like Joe Rogan or Alex Hormozi, the full archive reaches much further back.

What a simulation is, and isn’t

The people in the library are not participating in these conversations, and a profile does not mean they endorse Timbre. Every answer is generated by AI from public recordings. It can miss context, misread a passage, or apply an idea to a situation the person never discussed.

A profile reflects the recordings indexed so far, not everything a person has said. Steve Jobs’s profile, for example, is built entirely from archival footage. An answer is not financial, legal or investment advice. Open the source before relying on it. If you are one of the people profiled, or represent them, you can ask for a profile to be removed.
