✨ Features

1 Visual Model Support

LobeChat now supports OpenAI's latest gpt-4-vision model with visual recognition capabilities, a multimodal intelligence that can perceive visuals. Users can easily upload or drag and drop images into the dialogue box, and the agent will be able to recognize the content of the images and engage in intelligent conversation based on this, creating smarter and more diversified chat scenarios.

This feature opens up new interactive methods, allowing communication to transcend text and include a wealth of visual elements. Whether it's sharing images in daily use or interpreting images within specific industries, the agent provides an outstanding conversational experience.

2 TTS & STT Voice Speech

LobeChat supports Text-to-Speech (TTS) and Speech-to-Text (STT) technologies, enabling our application to convert text messages into clear voice outputs, allowing users to interact with our conversational agent as if they were talking to a real person. Users can choose from a variety of voices to pair with the agent.

Moreover, TTS offers an excellent solution for those who prefer auditory learning or desire to receive information while busy. In LobeChat, we have meticulously selected a range of high-quality voice options (OpenAI Audio, Microsoft Edge Speech) to meet the needs of users from different regions and cultural backgrounds. Users can choose the voice that suits their personal preferences or specific scenarios, resulting in a personalized communication experience.

Note

In the process of implementing this feature, we found that there was no satisfactory TTS (Text-to-Speech) frontend library available on the market. As a result, we invested a lot of effort, including data conversion, audio progress management, and speech visualization, among other tasks.

Important

Therefore, we decided to refine our implementation and make it open source, hoping to assist developers who wish to implement TTS. @lobehub/tts is a high-quality TTS toolkit developed in TypeScript, which supports usage both on the server-side and in the browser.

  • Server-side: With just 15 lines of code, you can achieve high-quality voice generation capabilities comparable to OpenAI's TTS service. It currently supports EdgeSpeechTTS, MicrosoftTTS, OpenAITTS, and OpenAISTT.
  • Browser-side: It provides high-quality React Hooks and visual audio components, supporting common functions such as loading, playing, pausing, and dragging the timeline. Additionally, it offers a very rich set of capabilities for adjusting the audio track styles.

3 Function Calling Plugin System

The plugin ecosystem of LobeChat is a significant extension of its core functionalities, greatly enhancing the practicality and flexibility of ChatGPT. By leveraging plugins, ChatGPT can perform real-time information retrieval and processing, such as automatically fetching the latest news headlines to provide users with immediate and relevant information. Moreover, these plugins are not limited to news aggregation but can also extend to other practical functions, such as quick document retrieval, e-commerce platform data access, and various third-party services.

Tip

To aid developers in joining this ecosystem, we provide comprehensive development resources in the 🧩 Plugin System section. This includes detailed component development documentation, a fully-featured software development kit (SDK), and template files—all designed to simplify the development process and lower the barrier to entry for developers.

Important

We welcome developers to use these resources to unleash their creativity and write feature-rich, user-friendly plugins. With collective efforts, we can continuously expand the boundaries of chat applications and explore a more intelligent and efficient creativity platform.

5 Progress Web App

Utilize the Progressive Web Application (PWA) technology to achieve a seamless CoolAI experience on your computer or mobile device. We deeply understand the importance of providing a seamless experience for users in today's multi-device environment. Therefore, we have adopted Progressive Web Application (PWA) technology, a modern web technology that elevates web applications to an experience close to that of native apps.

Through PWA, LobeChat can offer a highly optimized user experience on both desktop and mobile devices while maintaining its lightweight and high-performance characteristics. Visually and in terms of feel, we have also meticulously designed the interface to ensure it is indistinguishable from native apps, providing smooth animations, responsive layouts, and adapting to different device screen resolutions.

Note
If you are unfamiliar with the installation process of PWA, you can add CoolAI as your desktop application (also applicable to mobile devices) by following these steps:

  • Launch the Chrome or Edge browser on your computer.
  • Visit the CoolAI webpage.
  • In the upper right corner of the address bar, click on the Install icon.
  • Follow the instructions on the screen to complete the PWA Installation.

4 Theme Mode Selection

CoolAI offers two unique theme modes - Light Mode and Dark Mode, as well as rich color customization options to meet your personalized needs. By default, our themes will intelligently switch based on your system settings, but if you prefer manual control, you can easily switch in the settings.

6 Mobile Device Adaptation

We have carried out a series of optimization designs for mobile devices to enhance the user's mobile experience. Currently, we are iterating on the mobile user experience to achieve smoother and more intuitive interactions. If you have any suggestions or ideas, we welcome you to provide feedback through GitHub Issues or Pull Requests.

7 Theme Mode Selection

As a design-engineering-oriented application, LobeChat places great emphasis on users' personalized experiences, hence introducing flexible and diverse theme modes, including a light mode for daytime and a dark mode for nighttime. Beyond switching theme modes, a range of color customization options allow users to adjust the application's theme colors according to their preferences. Whether it's a desire for a sober dark blue, a lively peach pink, or a professional gray-white, users can find their style of color choices in LobeChat.

[!TIP]

The default configuration can intelligently recognize the user's system color mode and automatically switch themes to ensure a consistent visual experience with the operating system. For users who like to manually control details, LobeChat also offers intuitive setting options and a choice between chat bubble mode and document mode for conversation scenarios.

What's more

Beside these features, LobeChat also have much better basic technique underground:

  • 💨 Quick Deployment: Using the Vercel platform or docker image, you can deploy with just one click and complete the process within 1 minute without any complex configuration.
  • 🌐 Custom Domain: If users have their own domain, they can bind it to the platform for quick access to the dialogue agent from anywhere.
  • 🔒 Privacy Protection: All data is stored locally in the user's browser, ensuring user privacy.
  • 💎 Exquisite UI Design: With a carefully designed interface, it offers an elegant appearance and smooth interaction. It supports light and dark themes and is mobile-friendly. PWA support provides a more native-like experience.
  • 🗣️ Smooth Conversation Experience: Fluid responses ensure a smooth conversation experience. It fully supports Markdown rendering, including code highlighting, LaTex formulas, Mermaid flowcharts, and more.

✨ more features will be added when LobeChat evolve.

Deploy with Vercel Deploy with Zeabur

Keep Updated

If you have deployed your own project following the one-click deployment steps in the README, you might encounter constant prompts indicating "updates available." This is because Vercel defaults to creating a new project instead of forking this one, resulting in an inability to detect updates accurately.

Important
We suggest you redeploy using the following steps, 📘 Maintaining Updates with CoolAI Self-Deployment.


B Deploying with Docker

We provide a Docker image for deploying the CoolAI service on your own private device. Use the following command to start the CoolAI service:
