Who each workflow fits

Muse is aimed at personal, consumer tasks. Chords is aimed at work that belongs to a project on a computer you control. The overlap is the background assistant model, not the tools each one can reach.

Lyre may fit when you…

  • Want the assistant inside a repository, terminal and toolchain on your own computer.
  • Want to choose the model and provider rather than using the vendor’s model.
  • Need project files to remain in place and editable outside Lyre.
  • Want interactive app previews and App-only sharing for paired devices.

Muse may fit when you…

  • Want help with everyday consumer tasks across Gmail, Calendar, Instagram and shops.
  • Want the agent to keep working without your computer being awake.
  • Prefer a managed app with a free tier and no host to configure.
  • Are in a market where Muse and its connectors are available.

Meta designed Muse to act across the consumer internet from its own cloud computer. Lyre designed Chords to keep working where your project and tools already are.

When Muse is the better choice

  • Your tasks are personal and consumer-facing rather than repository work.
  • You want the vendor to manage the computer, credentials and security boundary.
  • You want a free tier for everyday use and do not want to configure a host.
  • You need the agent to continue while your own computer is closed.

Lyre does not replace Muse, and Muse’s connectors are not available in Lyre. If your work mostly happens in consumer apps, Muse is the closer fit.

Questions people ask before choosing

Is Lyre’s Chords the same thing as Muse?

No. Muse is Meta’s personal AI agent, built around a secure cloud computer and consumer apps and websites. Chords is Lyre’s early-access system of background assistants that run in projects on your own computer.

Where does each one keep my data?

Chords keeps project files and agent processes on the computer you select; prompts and selected context go to the model provider you configure. Meta says Muse runs on Muse Secure VM, a dedicated cloud computer that stores connected-service credentials.

Can a Chords bot shop, book or send messages for me?

A Chords bot does what its configured tools and permissions allow on your computer and through connected services. Lyre does not include Muse’s consumer connectors, and a Chords bot cannot act outside the permissions you approve.

Do I need an account to use Chords?

Local use of Lyre does not require a Lyre account. A model provider account is still required, and hosted features, remote viewing and Lyre AI follow their own plan facts.

Does a Chords bot keep running when I close my laptop?

No. The host must remain awake and reachable. Muse is designed to keep working in Meta’s cloud, which is the main availability difference between the two.

Muse, Meta, Instagram and other product names belong to their respective owners. This comparison reflects public documentation checked in November 2026 and may not match later releases or availability in every market.
