10 Must-Have Codex Plugins: From Animated Videos & Mobile Apps to Office Automation

Introduction

Many people use AI coding tools only for Q&A. But in reality, by installing the right plugins, AI capabilities can be multiplied several times over—it can create product animations, lifestyle videos, web games, mobile apps, and even automatically operate your computer and browser.

This article provides hands-on demonstrations of 10 high-value plugins on the Codex platform, broken down into three categories: Video & Animation, Product Development, and Universal Tools—helping you quickly find the right AI efficiency solution. Other AI coding tools can also look for equivalent Skills or plugins to use.

Video & Animation Plugins: Generate Professional-Grade Videos with Code

Hyperframe — A Powerhouse for Creative Animation & Visual Packaging

Hyperframe leans toward creative animation and visual packaging, making it ideal for product promos, title cards, motion graphics, and soft video animations—content that emphasizes visual expression.

Videos generated purely through code already achieve remarkably smooth and polished results. Without prior disclosure, they could easily pass as work from professional teams. For example, one user created an Apple phone clean room animation effect with Hyperframe that looked extremely professional.

Target audience: Content creators, marketers, and growth professionals who want to quickly produce eye-catching videos—Hyperframe is your go-to.

Remotion — Engineered Video & Batch Automated Generation

Remotion leans toward engineered video and automated generation, making it suitable for data-driven videos, ranking videos, reusable templates, and content that needs to be batch-generated through code.

For example, data-driven videos like national box office rankings can be efficiently template-produced using Remotion. If you want to create reusable templates and data videos while streamlining your content production pipeline, Remotion is the better fit.

Technical Background: Remotion is a programmatic video generation tool built on the React framework, with the core philosophy of "describing video with code." Unlike traditional video editing software, Remotion treats each frame as the render output of a React component, using timeline parameters to control animation states, with a headless browser (Headless Chrome) capturing frames one by one to compose the final video. This architecture makes data-driven video production possible—simply swap the data source and templates automatically generate fresh content, naturally suited for batch production of rankings, reports, news broadcasts, and similar scenarios. This also explains why Remotion is popular among developers: video logic can be version-controlled, reused, and collaborated on just like code.

Key difference between the two: Hyperframe emphasizes creative expression; Remotion emphasizes engineering efficiency. We recommend everyone working in content, conversion, or growth invest time learning both.

Product Development Plugins: From Design Mockups to Published Apps

Figma Plugin — AI-Powered Rapid Design Mockups

The first step in building a product is creating design mockups. The Figma plugin helps you draw prototypes, turning a vague idea into a complete set of product pages.

As the most mainstream collaborative design tool today, Figma's plugin ecosystem is built on the Figma Plugin API, allowing third-party developers to directly manipulate the node tree of design files. AI design plugins typically convert natural language descriptions into structured UI component parameters, invoke pre-trained layout models to generate page structures that comply with mobile design specifications (such as iOS Human Interface Guidelines or Material Design), and then write them to the Figma canvas via API. This workflow compresses what traditionally takes hours of prototype design into minutes, making it especially suitable for quickly validating concept feasibility in the early stages of product development.

For example, input "create a cute-style fitness plan App" and it will deliver complete mobile interfaces—today's workout, organized plans, in-progress training pages—with unified color schemes and component styles. While relatively simple overall, it already provides the complete product structure needed for an App, which can be further refined for interactions or used directly as a foundation for development.

Web App / iOS / Android Development Plugins

Once you have design mockups, the next step is actually building the product:

• For web apps: Choose the web development plugin
• For iOS apps: Choose the iOS development plugin
• For Android apps: Choose the Android development plugin

In the hands-on demo, inputting "Please help me create a simple and fun AI tool matching game web page—click two matching AI tool cards to eliminate them" triggered the AI to start developing automatically. The final result included not only game logic but also designed sound effects and animations, with impressively high completion quality.

For iOS apps, simply invoke the corresponding plugin to convert the web game, wait a moment, and you'll receive an installation package. The same applies for Android apps.

Universal Tool Plugins: Complete Office Automation Coverage

These plugins are useful for virtually everyone, covering high-frequency scenarios like office work, research, organization, and reporting.

Spreadsheet Plugin — Data Analysis in One Sentence

Processing data, running analyses, and writing reports are nearly impossible without the spreadsheet plugin. For example, prepare a household bill for analysis, and it will list core metrics, categorical summaries, spending charts, and optimizable amounts—with negative cash flow balances highlighted in red.

If you did the cleaning, categorizing, statistics, and charting yourself, it would take at least half a day. With the spreadsheet plugin, one sentence produces complete results.

PPT Plugin — Auto-Generate Reports and Reviews

Building on spreadsheet analysis, the PPT plugin can further organize key points. For example, analyzing "where did all the money go" will:

1. Provide an overall spending overview for April
2. Break out major expense categories (dining, transportation, daily necessities)
3. Separately highlight small but frequent expenses (work meals, rides, coffee)
4. Offer saving suggestions and optimization plans

The overall completion quality is very high—clear structure, focused highlights, with both data conclusions and specific action recommendations. Perfect for routine report reviews, data analysis, and project presentations.

Computer Use — The All-Purpose AI Assistant That Takes Over Your Computer

Computer Use can directly take over your computer, access your logged-in browser, operate local software and files—moving the mouse, clicking buttons, typing text, switching windows, opening software, processing files, and even completing cross-application operations.

Technical Background: Computer Use originated from Anthropic's Claude computer use capability released in October 2024, marking an important leap from "language understanding" to "embodied operation." Its underlying principle works by taking screenshots to perceive screen states, combining visual understanding models to identify UI element positions, then outputting operation sequences like mouse coordinates and keyboard commands, forming a closed loop of "perception-decision-execution." The fundamental difference from RPA (Robotic Process Automation) is that traditional RPA relies on pre-defined fixed scripts that break when interfaces are redesigned; Computer Use can understand natural language instructions and dynamically adapt to interface changes without pre-recording operation flows, significantly lowering the threshold and maintenance cost of automation.

Any workflow you normally perform sitting at your computer can be handed off to AI—it can completely replace various automation tools that were previously popular.

Browser Use — Browser Automation & Information Extraction Expert

Browser Use lets AI control the browser, specifically handling web-based tasks: opening pages, reading content, extracting information, and organizing materials.

Technical Background: Browser Use is essentially an AI-enhanced automation tool built on headless browser frameworks like Playwright or Puppeteer. Compared to traditional crawlers, its biggest advantage is handling modern web pages that require JavaScript dynamic rendering, as well as scenarios requiring login states and CAPTCHA verification. More importantly, it introduces an LLM as an "understanding layer," no longer relying on fragile hard-coded rules like XPath or CSS selectors, but instead reading page content like a human to extract needed information—significantly reducing maintenance costs caused by website redesigns breaking scripts. This is also the most fundamental division of labor between it and Computer Use: Browser Use focuses on "understanding web content," while Computer Use focuses on "controlling the local environment."

A clever use case is an auto-updating personal knowledge base: bookmark valuable content on social media, then set up a scheduled task for AI to automatically scrape that content daily, extract core information, organize it into Markdown and store it in knowledge management software. Meanwhile, the AI also combines project goals for daily reviews, generating new knowledge strategies and action recommendations. Over time, this knowledge base becomes a personal brain that understands you better and better.

How to Choose Between Computer Use and Browser Use?

Scenario	Recommended Plugin
Requires local login state, desktop software, cross-application operations	Computer Use
Browsing web pages, scraping information, organizing materials	Browser Use
Concerned about permissions, don't want AI to take over the entire computer	Browser Use
