Capabilities
Your own model
that controls your Mac.
One sentence in, a real action out. Every card below is a tool family in tools.json — verified, not aspirational.
Calendar & Scheduling
Check your day, create events, find free slots, spot conflicts. Handles relative dates and recurring meetings.
Files & Finder
Spotlight search, open files, read documents, check storage. Finds the PDF even when you forgot its name.
Mail & Messages
Drafts and sends mail, checks unread, resolves contacts by name — and asks when there are two Daisys.
Music & Podcasts
Play, pause, skip, queue, volume. Search by artist or mood without leaving whatever you're doing.
System Controls
Volume, brightness, dark mode, Focus modes, battery, lock, sleep. Plain English in, settings out.
Multi-step chains
One sentence triggers calendar, mail, and reminders in sequence — the follow-through Siri never shipped.
Why Macaw
Everything Siri can't do.
Macaw does.
Same Mac, different brain. And unlike the waitlisted "coming soon" assistants, Macaw is live today with the source in the open.

How it works
Running in
three steps.
Install the app
Clone the repo, swift build, done. No installer to hunt for.
Press ⌥ Space
The floating bar opens from any app, any window, any time.
Type what you need
Plain English or fragments. Macaw picks the tool, runs it, returns the result.
Receipts
Measured, on an M2.
We measure without mercy. bench.py, one request per capability, top-12 retrieval — no hand-tuning between rows.
Compatibility
Runs on your Mac.
Not theirs.
Live today. Open source. Yours.
Weights on Hugging Face, code on GitHub, runs fully local. No waitlist, no pricing-at-launch.
The small print
Honest asterisks.
Base model is LFM2.5; the app injects a system prompt so it presents as Macaw.
MLX runs on Metal. BF16 weights run anywhere Transformers does.
LFM Open License v1.0 caps commercial use at $10M revenue. The code is MIT.
Code is MIT; weights inherit the LFM Open License v1.0 from LFM2.5. MLX: aa045fad…e238 · BF16: 966d2066…8be0.
