## AI Code Preview

AI coding assistants hand you code as text, and checking whether that code actually works usually means copying it into a separate editor or a throwaway page. AI Code Preview removes that step. As soon as an AI response contains a code block, the extension detects it and gives you a live preview of what the snippet renders, directly alongside your conversation.

The extension supports the formats developers hit most often when working with AI tools: HTML, CSS, and JavaScript, plus React components and Vue single-file components. From the same panel you can copy the code or download it, and snippets run in an isolated sandbox so testing AI-generated output does not interfere with the rest of your browsing.

It is a free Chrome Web Store extension with a small, dedicated following and strong ratings. It is best understood as a focused verification tool — a way to confirm that AI-generated markup, styles, and components behave as intended before you commit them to a project.

**Pricing & Plans:** AI Code Preview is free. It is a free Chrome Web Store extension with no listed paid tier.

- **Real-time code preview:** See the rendered output of a code snippet immediately, without copying it into a separate editor or sandbox.
- **Multi-language support:** Preview HTML, CSS, and JavaScript together, as well as React components and Vue single-file components.
- **One-click copy and download:** Copy a snippet to your clipboard or download it as a file straight from the preview panel.
- **Smart code-block detection:** The extension recognizes fenced code blocks and their syntax automatically, so previews appear without manual setup.
- **Sandboxed execution:** Code is executed in an isolated sandbox, so you can test AI-generated snippets without risking your environment.

**Strengths:** Free Chrome Web Store extension with no paid tier; Live preview of HTML, CSS, JS, React, and Vue snippets; Sandboxed execution keeps testing isolated; Quick copy and download straight from the preview

**Limitations:** The listing was last updated in 2024, so very new frameworks may not yet be covered; Focused purely on previewing snippets — it is not a full IDE or project-level build tool

## ERNIE Comate

ERNIE Comate, known in Chinese as Wenxin KuaMa, is Baidu's entry into the crowded AI pair-programming market. Rather than a standalone chat app, it is designed as an in-editor companion: after installing the plugin, developers get inline suggestions, whole-function generation from a natural language comment, and context-aware answers without leaving their working file. The underlying ERNIE model is tuned for code, so the assistant can handle everything from boilerplate scaffolding to unfamiliar legacy modules.

The tool covers the full inner development loop. Beyond autocompletion, it generates unit tests, drafts docstrings and comments, proposes refactors, and can flag questionable patterns during code review. It also accepts non-code context such as documents and images, which helps when you need to translate a design mock or a written requirement into working code. Baidu positions the assistant as a way to compress the repetitive parts of engineering work so that developers spend more time on design and problem solving.

Deployment options span personal use through to enterprise environments, with a freemium model: a free tier for casual use and paid or enterprise arrangements for teams that need higher quotas, administrative controls and support. Because the product lives inside the IDE and works across hundreds of languages, adoption does not require teams to change their existing toolchain.

**Pricing & Plans:** Freemium. A free tier is available for individuals, while paid individual plans and enterprise licensing add higher usage quotas, team administration and support. Check the official site for current tiers and regional pricing.

- **Inline code completion:** Context-aware suggestions appear as you type, completing lines, functions and whole blocks in the style of the surrounding codebase.
- **Natural language to code:** Describe what you need in plain language and Comate drafts the implementation, from single helper methods to full module skeletons.
- **Test, comment and docstring generation:** Automatically produce unit tests, explanatory comments and documentation for existing functions to raise coverage and readability.
- **Code review and refactoring:** Scan changes for potential defects, suggest simplifications and refactor legacy code while preserving intended behaviour.
- **Broad language and IDE support:** Works across hundreds of programming languages and integrates with mainstream IDEs and editors, so teams keep their current workflows.

**Strengths:** Deep integration with the ERNIE model family and Chinese-language code and comment understanding; Covers the whole loop: completion, generation, testing, commenting and review in one plugin; Freemium entry point makes it easy to trial without procurement

**Limitations:** Documentation and community discussion are concentrated in Chinese, which can slow adoption for non-Chinese-speaking teams; Advanced quotas and administrative features sit behind paid or enterprise plans; Best model quality is tied to Baidu's own ecosystem rather than letting you bring any external model
