Noi is a free, open-source browser designed to consolidate access to AI services like ChatGPT, Claude, and Gemini from a single interface. Instead of managing multiple tabs and logins, users can interact with different AI models side by side.
One Browser App for ChatGPT, Claude, Gemini, and More
Noi primarily targets users who frequently engage with multiple AI models, such as developers, researchers, and power users. It’s designed to reduce "AI Fatigue" by streamlining workflows. Specific use cases include quickly cross-referencing responses from different AI services, efficiently managing and reusing AI prompts, and handling multiple accounts for the same AI service without login conflicts. The tool excels at enabling simultaneous interaction with various AI models, speeding up comparison and analysis.
Tab Management, Quick Commands, and Multi-Model Chat
Noi functions as a custom browser designed specifically for AI interactions. It allows users to access and manage services like ChatGPT, Claude, and Gemini from one application. Key features include:
- Multi-Window Management: Organize and view multiple AI interfaces simultaneously.
- Noi Ask: Send a single prompt to several AI models concurrently and compare their responses in one view.
- Prompt Management: A native system for saving, tagging, and reusing prompts, offering a more organized approach than external notes.
- Multi-Account Mode: Utilize cookie isolation to manage different accounts for the same AI service without login conflicts.
- Caching Mode: Quickly switch between links with cached content in the sidebar for enhanced efficiency.
- Customization: Personalize the browsing experience by adding any URL and choosing from customizable themes.
Noi supports a wide array of AI models, including ChatGPT, Claude, Gemini, Bard, Copilot, Ollama, Perplexity, Qwen, DeepSeek, Grok, HuggingChat, and Suno. It also allows for the addition of arbitrary URLs, making it highly adaptable.
Electron-Based Desktop App with Cross-Platform Support
Developed by lencx and primarily written in TypeScript, CSS, and JavaScript, Noi is available for Windows, macOS, and Linux operating systems. It includes a built-in terminal for local commands and a noi CLI command for integration with other tools. The browser emphasizes local-first data storage, ensuring that history, prompts, and settings remain on the user’s device. This design choice, along with cookie data segregation, aims to enhance user privacy.
Free and Open-Source on GitHub
Noi is a free and open-source tool. There are no subscription fees or costs associated with using the application itself. Users are responsible for any costs or usage limits imposed by the individual AI models (e.g., ChatGPT, Claude, Gemini) they access through Noi, as the application acts as a unified interface to their web versions.
Requires Own API Keys, No Built-in Models
While Noi aims to simplify AI interactions, some services within it may still require users to have existing accounts and log in. Although Noi emphasizes local-first data storage, general concerns have been raised about the privacy of "AI browsers" due to their potential access to browsing data. Users should verify how their data is handled by individual AI services accessed through Noi. Some users also express skepticism about the utility of AI browsers, viewing them as mere "wrappers" for existing AI services, and technical issues have been reported by some users, though the developer maintains a dedicated support team.
