Simple by design

How OmniKey works

Three steps, zero friction. Works in every app on your computer.

Select any text

Highlight text in any application — emails, documents, code editors, chat apps.

Press a shortcut

Use ⌘E, ⌘G, or ⌘T to trigger the AI enhancement.

AI enhances in-place

The result is automatically pasted back, replacing your selected text. No copy-paste needed.

Keyboard shortcuts

Three powerful commands

Each shortcut maps to a specific AI capability, available in any app on your screen.

⌘E

Enhance Prompt

Rewrite selected text with better clarity, structure, and tone — ideal before sending to any AI tool.

⌘E macOS · Ctrl+E Windows

⌘G

Grammar & Clarity

Fix spelling, grammar, and readability without changing the core meaning of your text.

⌘G macOS · Ctrl+G Windows

⌘T

Custom Task + Agent

Apply your own saved instructions or run the AI agent with real-time web search and terminal access.

⌘T macOS · Ctrl+T Windows

Advanced usage

Unlimited flexibility with @ commands

Prefix your text with @ to give OmniKey specific instructions on the fly.

⌘E

Enhance a Prompt

Select any text in any app and press ⌘E (macOS) or Ctrl+E (Windows). OmniKey rewrites it with better clarity, structure, and tone — ideal before sending to an AI tool.

⌘G

Fix Grammar & Clarity

Select text and press ⌘G / Ctrl+G. OmniKey corrects spelling, grammar, and readability without changing your meaning.

⌘T

Run a Custom Task

Set up your own task instructions in the Task Instructions tab in the menu bar app. Then select any text and press ⌘T / Ctrl+T to apply them.

Ask OmniKey Anything

Start your text with @omnikeyai followed by any instruction. Select it and press any OmniKey shortcut — OmniKey takes action based on what you write and pastes the result in place.

@omnikeyai write this text into valid markdown format

🤖

Run the AI Agent

Start your instructions with @omniAgent, select them, and press ⌘T / Ctrl+T. The agent gathers context from your terminal and the web, combines your saved task instructions if configured, then completes the task and pastes the result.

macOS & Windows

Authenticated Browser Session Reading

OmniKey reads content directly from your live browser tab — including pages that require login. The @omniAgent can work with private dashboards, internal docs, and authenticated tools without any copy-pasting.

Works with: Chrome, Brave, Edge on Windows · Chrome, Brave, Edge, Arc, Vivaldi, Opera, Chromium, Safari on macOS.

Recommended: one command does everything

omnikey grant-browser-access

The CLI detects your installed browsers, creates a dedicated Omnikey debug profile stored at ~/.omnikey/browser-debug-profiles/, finds a free debug port, registers a permanent login startup entry, and verifies the connection — all in one guided flow.

Because a fresh profile is used, you sign in to your accounts once inside it. Your main browser profile is never touched, and the debug profile persists between sessions.

After setup, reopen the browser with its Omnikey debug profile any time using:

omnikey browser open

Manual setup

Remote Debugging Port (CDP)

Modern Chrome no longer allows --remote-debugging-port with your existing user profile. You must point --user-data-dir at a dedicated, separate directory.

Create a folder for the Omnikey debug profile — e.g.:

mkdir "$env:USERPROFILE\.omnikey\browser-debug-profiles\chrome-default"

Close all Chrome windows completely (check Task Manager → Details for any remaining chrome.exe processes).

Launch Chrome pointing at the new profile — paste into PowerShell:

& "C:\Program Files\Google\Chrome\Application\chrome.exe" `
  '--remote-debugging-port=9222' `
  "--user-data-dir=$env:USERPROFILE\.omnikey\browser-debug-profiles\chrome-default" `
  '--no-first-run' '--no-default-browser-check'

A fresh Chrome window opens. Sign in to your accounts — this profile persists, so you only do this once.
Confirm the port is active: http://127.0.0.1:9222/json
To auto-start on login, add this command as a Registry Run value under HKCU\Software\Microsoft\Windows\CurrentVersion\Run.

Edge: replace chrome.exe with msedge.exe. Brave: use brave.exe.

Remote Debugging Port (CDP) — Chrome, Brave, Edge, Arc, Vivaldi, Opera, Chromium

Modern Chrome requires a separate --user-data-dir for remote debugging — using your existing profile is no longer supported.

Create a folder for the Omnikey debug profile:

mkdir -p ~/.omnikey/browser-debug-profiles/chrome-default

Quit the browser fully (⌘Q).

Launch it from Terminal pointing at the new profile:

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
  --remote-debugging-port=9222 \
  --user-data-dir="$HOME/.omnikey/browser-debug-profiles/chrome-default" \
  --no-first-run --no-default-browser-check

A fresh browser window opens. Sign in to your accounts — this profile persists between sessions.
Confirm the port is active: http://127.0.0.1:9222/json
To auto-start on login, create a launchd plist at ~/Library/LaunchAgents/com.omnikey.browser-debug.plist with RunAtLoad = true pointing to the same command.

Replace the app path for Brave (Brave Browser.app), Edge (Microsoft Edge.app), etc. Use a different folder name per browser.

Chrome, Brave, Edge, Arc, Vivaldi, Opera, Chromium

In the menu bar go to View → Developer → Allow JavaScript from Apple Events.
Make sure it is checked, then restart the browser.

Safari

Go to Safari → Settings → Advanced and enable "Show features for web developers".
Then go to Develop → Allow JavaScript from Apple Events and make sure it is checked.

No separate profile or port needed — Omnikey reads your existing open tabs directly. This is a permanent one-time setting.

Automation

Scheduled Jobs

Run prompts automatically on a recurring schedule or at a one-time date and time.

App

Use Scheduled Jobs in the Desktop App

Open Scheduled Jobs from the OmniKey menu bar (macOS) or system tray (Windows). You can:

Create recurring jobs using weekday/day selection and time
Create one-time jobs for a specific date and time
Run jobs immediately with Run Now
Enable/disable jobs with Activate and Deactivate
Inspect the last execution with Last Run

CLI

Manage Scheduled Jobs from the CLI

Use the schedule command group to add, list, remove, and trigger jobs:

omnikey schedule add
omnikey schedule list
omnikey schedule remove
omnikey schedule run-now <job-id>

The add flow is interactive and supports multiline prompt input, recurring cron schedules, and one-time jobs.

Quick setup

Up and running in minutes

Four simple steps to get OmniKey working on your machine.

Install the CLI

Install the OmniKey CLI:

brew install GurinderRawala/omnikey/omnikey-cli

npm install -g omnikey-cli

Onboard & configure your AI provider

Run the interactive setup to pick your LLM provider and enter your API key:

omnikey onboard

Supports OpenAI, Anthropic, and Google Gemini. You can also optionally configure a web search provider. Supported web search providers: DuckDuckGo, Serper, Brave Search, Tavily, SearXNG.

Start the daemon

omnikey daemon

On macOS this registers a launchd agent. On Windows it registers a Task Scheduler task.
