GroundSlate

The ultimate AI companion for creators on macOS

Point it at your footage. It indexes every frame, face, word and place on your Mac, then hands the library to your AI assistant as a backend that cuts the video.

Turn your AI agent into a video powerhouse

It finds the footage, cuts it, mixes it, creates graphics, generates what is missing, and produces finished videos.

The workspace

The workspace

Your assistant drives it, but the library is yours to open. Everything it indexes is here to inspect, correct and cut from.

You decide what your AI is allowed to know.

Where do you want to work?

GroundSlate does the work. Your AI app is where you ask for it. Pick the ones you use and it wires itself in.

What should your AI know about people?

What your agent gets

Connect the one you already use. This is what it can do the moment you do.

It watches everything

Enrich your metadata for video, photos, and audio.

Face detection, scene description, text, and transcription all with open source local models that run on your Mac. Powered by Google Gemma and other AI tools or bring your own model for vision and reasoning through Ollama.

Hours, not clips

Long recordings can be indexed at all

Most tools cap you at a clip length. This takes a two hour recording whole, and a reprocess lets you choose standard, detailed or maximum sampling.

External drives

Find the shot on old drives

Index a drive once and everything on it stays searchable by thumbnail and metadata with the drive sitting on a shelf. Plug it back in when you want to make something with it. Your media never moves, and watch folders keep indexing in the background.

Fast rendering

Renders run through hardware acceleration on your Mac Silicon

Every asset runs on your own tools and pipeline. A graphics render that takes 42 seconds in a cloud sandbox finishes in 8 here, and the gap compounds with every video.

Instant recall

Save up to 43x on AI cloud tokens per clip

Indexed once on your Mac, a clip answers from 511 tokens of text instead of the 22,128 it costs for a cloud AI to sample, and the text carries the speech, which frames cannot.

Scoped access

Your agent reaches exactly as far as you allow

You grant folders one at a time, read-only or writable. An assistant cannot add one itself, and everything outside them is unreachable.

Privacy mode

Tokenized names to reduce AI visibility

Switch on privacy mode and the names in your People catalog become tokens to your AI agent. People are referenced by ID only, increasing anonymity while keeping your ability to search for individuals in your footage. Biometrics are never shared with your AI.

Host or bridge

The library on one Mac, your AI apps on another

The host Mac holds the library and does all the indexing and rendering. A bridge is a second Mac running the same app as a menu bar agent: pair it over your network with a six digit code, and the AI apps on it drive the host's library, with finished renders fetched back to its own Movies folder. No separate licence for a bridge.

Avatar kits

A brand kit for your virtual influencers

Your Mac becomes a provider agnostic repository of your people and characters, holding their images, video, voice and backstory. Easily reference AI people or characters to generate new AI content, and download every generation into a local catalog that can be used to build long form videos.

Prompt library

Your AI Image prompts stop living in chat windows

Your agent generates wherever you already have an account, then pulls the file down to your Mac with the prompt, the references, the model and the seed recorded beside it.

GroundSlate is optimized to take advantage of the shared memory of the CPU and the GPU on Apple silicon. That architecture allows your M-series Mac to run advanced AI locally, with privacy, speed, and lower costs.

Local processing

It all happens on your machine.

Your footage
Processed on your own silicon

Indexing, transcription and rendering all run on the Apple silicon in the Mac you already own.

Faces
Biometric data stays put

Created on your machine, kept on your machine. Privacy Mode tokenizes the names you have catalogued.

Us
A licence, and a benchmark if you send one

No analytics or telemetry. We hold your login and license key, and a machine identifier when you activate. A speed test of the app's own sample files reaches us only when you press Send to COEY. We process no content at all.

For agencies and brands
Your NDA already answered this

A client's unreleased footage cannot go to a cloud service. Here it stays on the Mac it landed on.

For everyone else
It is your whole life in there

Ten years of everywhere you went, and everyone you went with. Searchable on your own machine.

What you send your assistant is between you and whoever runs it. All of it is written down in the privacy supplement.
