Why Multivac

A calmer way to work with many models.

Send one prompt to every model at once. See speed, tokens, and cost next to each answer — pick the best.

Conversations and keys live on your disk, never our servers. Run fully offline with local models.

Pay providers directly at cost — no markup, no subscription. Track spend per model in real time.

Privacy

Multivac is a desktop app. There’s no account, no telemetry, and nothing leaves your machine except the API calls you choose to make.

Local-first SQLite storage you can read and export

Keys encrypted in your OS keychain

$ multivac status
