About

Local-first software, built by one developer who uses it.

MultiAgentAI is the home of MultiAgentOS and a family of native Mac apps built by Luke Kevin McLaughlin. The common thread across everything here: the software runs on your own machine, your data stays with you, and you are not renting access by the month.

Who builds this

These products are built by Luke Kevin McLaughlin, an independent developer working across on-device AI, native macOS apps, and data and AI engineering. You can find more at his personal site and on GitHub. Sister projects include LLM Browser, Jobomate, Math Logic Code, and Constructing Language.

What we make

The flagship is MultiAgentOS, a local-first desktop AI agent for Mac and Windows: plug in a cheaper provider API or a private local model and put it to work with a full desktop tool harness. Around it is a growing family of focused, native Mac apps, each doing one job well and on-device:

  • VideoNotes turns lecture videos into source-cited study notes.
  • Lectern transcribes meetings on-device and keeps a searchable archive.
  • Shorts builds a short-form first cut from a brief; Broadcut streams and edits in one app.
  • Sift declutters photo libraries; SpaceLens maps and cleans your disk.
  • Recast converts files locally; Tidyset cleans spreadsheets; Alembic prepares AI datasets.

What we believe

Three principles run through all of it:

  • On-device by default. Your lectures, meetings, photos, files and data are processed on your Mac, not uploaded to someone else's server.
  • Own it, don't rent it. On this website every app is a fully activated download supported by a donation, with no subscription and no account.
  • Deterministic and inspectable. Pipelines replay identically, actions are reviewable, and removals are recoverable. Software should be predictable and honest about what it does.
