Building an AI-Powered Filename Generator Chrome Extension

Introduction

Managing files efficiently can be a challenge, especially when dealing with vague or cluttered filenames. To solve this, I developed the **AI Filename Generator**—a Chrome extension that intelligently renames files based on their content. This blog post will walk you through how I built it using my open-source repository: [chrome-ai-filename-generator](https://github.com/kliewerdaniel/chrome-ai-filename-generator).

You can also install the extension directly from the Chrome Web Store: [AI Filename Generator](https://chromewebstore.google.com/detail/ai-filename-generator/eocbkbnabbmclgneeakdbglicbhbimbj).

By the end of this post, you'll understand the core technologies used, how to set up the extension, and the process of integrating AI into a simple yet effective Chrome tool.

Why Build an AI Filename Generator?

I often download files with generic names like document.pdf, image123.jpg, or scan_2024.png. Instead of manually renaming them, I wanted a tool that could:

• Analyze the file contents (text or metadata)
• Generate meaningful, structured filenames automatically
• Seamlessly integrate into Chrome’s download flow

This extension enhances productivity by making file organization smarter and faster.

Tech Stack Overview

This Chrome extension is built using:

• **Manifest v3** – The latest Chrome extension framework
• **JavaScript & HTML/CSS** – For frontend interactions
• **OpenAI API** (or local AI models) – For intelligent filename generation
• **Chrome Downloads API** – To modify filenames upon download
• **Webpack & Babel** – For modern JavaScript compilation

How It Works

The AI Filename Generator intercepts file downloads and renames them using AI-generated suggestions. Here’s the high-level workflow:

1. **Intercept a File Download** - Using Chrome’s downloads.onDeterminingFilename API, the extension listens for download events. 2. **Analyze File Metadata** - Extracts information like file type, source URL, and content (if accessible). 3. **Send Data to AI Model** - Requests a relevant filename based on context. 4. **Rename the File** - Modifies the filename before saving it to disk.

Setting Up the Extension

Want to try it out or contribute? Follow these steps:

1. Clone the Repository

sh git clone https://github.com/kliewerdaniel/chrome-ai-filename-generator.git cd chrome-ai-filename-generator

2. Install Dependencies

sh npm install

3. Build the Extension

sh npm run build

4. Load the Extension in Chrome

1. Open chrome://extensions/ 2. Enable **Developer Mode** (top-right corner) 3. Click **Load Unpacked** and select the dist/ folder

Key Features Explained

1. **Intercepting Downloads**

javascript chrome.downloads.onDeterminingFilename.addListener((downloadItem, suggest) => { const originalFilename = downloadItem.filename; getAIEnhancedFilename(originalFilename).then((newFilename) => { suggest({ filename: newFilename }); }); });

This snippet listens for file downloads and passes the filename to our AI function.

2. **Generating AI-Based Filenames**

javascript async function getAIEnhancedFilename(originalName) { const response = await fetch("https://api.openai.com/v1/completions", { method: "POST", headers: { "Authorization": Bearer ${OPENAI_API_KEY}, "Content-Type": "application/json" }, body: JSON.stringify({ model: "gpt-4", prompt: Suggest a meaningful filename for: ${originalName}, max_tokens: 10 }) }); const data = await response.json(); return data.choices[0].text.trim(); }

This function calls OpenAI’s API to generate a more descriptive filename based on the original one.

Future Improvements

While the current version is functional, there are some enhancements I plan to explore:

• **Local LLM Support** – Allowing users to run filename suggestions without an internet connection.
• **Content-Based Naming** – Extracting text from PDFs/images to generate even more accurate filenames.
• **Customization Options** – Letting users define filename formats (e.g., date-based, project-based).

Conclusion

The AI Filename Generator Chrome extension is a small but powerful tool that enhances file organization. By leveraging AI, we can automate mundane tasks like renaming files, ultimately improving productivity.
