Chromeウェブストアより

All-in-One AI Assistant powered by AI Models: writing enhancement, quick actions, and smart utilities Omni AI: Your All-in-One AI Writing & Browsing Assistant

Omni AI puts the world's leading AI models directly inside your browser, so you never have to switch tabs again. Highlight any text on any page, whether it is an email you are drafting, a GitHub comment, a research paper, or a foreign article, and get instant AI help right where you are working.

WHY INSTALL IT The AI you already pay for, working on the pages you already use. No new subscription, no copying text back and forth between browser and ChatGPT/Gemini/Claude, and no lock-in to a single provider. Omni AI bolts AI onto your normal workflow instead of pulling you into another tab.

WHAT IT DOES

Fix Grammar & Spelling: polish anything in one click
Rephrase: get fresh, natural wording every time
Summarize: turn a 10-minute read into a 30-second one
Change Tone: Professional, Casual, Friendly, Direct, or Confident presets
Explain: break down jargon, legal text, or technical concepts
Translate: 43 languages, from Spanish, French and German to Hindi, Arabic, Thai, Vietnamese and both Simplified and Traditional Chinese. Set a primary language for one-click translation, or use Smart Translate, which auto-detects the source language for you.
Add Emoji: liven up a message in one click

Works in plain inputs, textareas, and rich-text editors such as TinyMCE. Trigger it from the floating button, the right-click menu, or keyboard shortcuts. A side panel adds one-click Summarize, Smart Translate, and Explain for the whole page you are reading.

THE INTERFACE SPEAKS YOUR LANGUAGE The entire extension interface ships in 52 locales, covering 46 languages. Six of those locales are regional variants: British English, Canadian French, Latin American Spanish, European Portuguese, and Traditional Chinese for Hong Kong and Taiwan. All 52:

Arabic, Bengali, Bulgarian, Catalan, Simplified Chinese, Traditional Chinese (Hong Kong), Traditional Chinese (Taiwan), Croatian, Czech, Danish, Dutch, English, British English, Finnish, French, Canadian French, German, Greek, Gujarati, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Kannada, Kazakh, Korean, Lithuanian, Malay, Malayalam, Marathi, Norwegian, Odia, Polish, Portuguese, European Portuguese, Punjabi, Romanian, Russian, Slovak, Slovenian, Spanish, Latin American Spanish, Swedish, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, Vietnamese.

WHAT MAKES OMNI AI DIFFERENT Most AI extensions lock you into a subscription and a single model. Omni AI does not.

Bring Your Own Key (BYOK): use your own API key for Google Gemini, OpenAI, Groq, or Anthropic Claude. Pay the provider directly for what you actually use, nothing more.
Custom Gateway Support: connect any OpenAI-compatible endpoint, such as DeepSeek, OpenRouter, a self-hosted proxy, or your own gateway.
Universal Editor Support: plain inputs, textareas, and contenteditable rich-text editors across the web.
Clean, Focused UI: a glassmorphic floating button appears where you are working and gets out of the way when you do not need it (it can be turned off entirely in Settings).

QUICK SETUP Omni AI needs one API key to work. Pick a provider:

Google Gemini: aistudio.google.com/app/apikey (free tier available)
OpenAI: platform.openai.com/api-keys
Groq: console.groq.com/keys (fast inference, free tier available)
Anthropic Claude: console.anthropic.com/settings/keys
Custom Gateway: enter your base URL, key, and model in Settings

KEYBOARD SHORTCUTS

Alt+O: Show the Quick Actions menu at the current selection
Alt+R: Rephrase selected text
Alt+T: Smart Translate selected text
Alt+F: Fix Grammar on selected text

Quick Ask, Summarize, and Explain are also available as commands. Assign your own shortcut (and customize any of the above) at chrome://extensions/shortcuts.

USAGE DASHBOARD Settings → Usage shows total actions run, words processed, and words generated, a quick look at how much time Omni AI is saving you.

PRIVACY

No middlemen: your browser talks directly to the AI provider's API. We do not operate a backend that sees your prompts.
No tracking: no browsing history, prompt logging, or identity collection.
Local storage only: your API keys stay in your local Chrome profile.

Install Omni AI and bring AI to every tab you open.
