A council of models.
One answer.
Several models running on your own Mac argue one question out, and one of them writes the answer. Offline by default.

It all happens on your Mac.
Chat, a coding agent, images and dictation.
No account, no cloud, no telemetry.
A Roundtable: two seats argue, the chair writes the answer.
Made for people who already run their own models.
One model is a guess. A room is an answer.
Give a hard question to several models with different roles, run a few rounds of disagreement, then hand a chair model the transcript to weigh the arguments and write the reply. It is the one thing a single model, and the tools that only run one, cannot do.
- Pick the seats, assign roles, set the rounds
- Local seats by default, add a cloud seat only if you want one
- Watch the debate, keep the synthesis
"Design a rate limiter for our API."
Three seats debate, the chair synthesizes
Seven surfaces, one native app.
Each one otherwise means a separate tab or a separate purchase. Slate keeps them side by side, and keeps the work on your machine.
Roundtable
Seat several local models, give them roles, and let them argue across a few rounds. Then one chair model reads the whole transcript and writes the answer.
- Pick the seats & roles
- Local by default
- Keep the synthesis
Chat
Open a focused conversation with any GGUF you bring, drop in a file or an image, and let it read your own documents on device before it answers.
- Any local model
- On-device file chat
- Editable memory
Code
Point Slate at a project. Ask reads only, Edits proposes diffs you approve, Auto runs the loop, and a checkpoint rolls you back when the plan beat the patch.
- Ask / Edits / Auto
- Checkpoints & Git
- Per-project memory
Image
Run local diffusion models with the prompt kept on the machine. Start from text, rework a source frame, hold a seed to iterate, then drag the result onward.
- Text & image to image
- Seed control
- Fully on device
Voice
On-device speech in and out, with turn detection and interruption handling, so it feels like a conversation instead of a dictation box. Nothing hits a cloud transcriber.
- Local STT & TTS
- Turn detection
- No cloud
Flow
Dictate into whatever app already has focus. Slate transcribes locally, cleans the result, and drops it at your cursor, in German or English, with your own vocabulary.
- Push-to-talk anywhere
- Local cleanup
- DE / EN + vocab
Slate Remote
Pair your iPhone with a QR code and chat with your Mac's models from the couch. Every token streams live over an encrypted link — home Wi-Fi only, nothing leaves your network. The iPhone app is not released yet; the Mac side ships today.
- Pair by QR
- Live streaming
- Home network only
Local by default. Open by design.
"Your work stays on your Mac" is only worth saying if you can check it. So the engine is open: read it, build it, and confirm there is no hidden call home.

Cloud by choice

Free to run. Worth paying for.
The everyday workspace is open source and free. One payment unlocks the rest, forever. No subscription, no account. What running it costs you in electricity.
The local workspace, in the open. Bring a model and start; no key, no card.
- Local chat with any GGUF you bring
- Chat with your files, on device
- Roundtable with two seats
- Code in Ask mode, read-only
Every surface unlocked, on up to three Macs. One payment, yours to keep.
- The full Roundtable, deeper synthesis
- Flow dictation, system-wide
- Agentic coding, images and voice
- Memory, model compare, local tools & MCP

Open it
No account, no licence key, no sign-in. It is signed and notarized by Apple, so it opens on a double-click.
Take the model it suggests
Slate bundles no models, so it reads your Mac's memory and recommends one that fits: about 7 GB on a 16 GB Mac, 10 GB on 24 GB, 16 GB on 32 GB. One button, downloading in the background. Or pick your own from Hugging Face. See what fits your Mac, or the honest version for an 8 GB machine.
Ask it something
The answer is computed on your Mac. Nothing is sent anywhere unless you add a cloud key yourself, and Silent Mode blocks even that.
Needs macOS 26 on Apple silicon. On an Intel Mac or an older macOS it will not run, and we would rather you knew that now than after the download.
