🛠️ Installation & Quick Start Guide 🛠️

📦 Installation (Let's Get This Party Started!)

Alright, since this isn't (yet?) on the Chrome Web Store (because who has time for reviews? 🙄), you gotta load it manually like a true tech wizard (or someone who can follow instructions).

Grab the Goods 🛍️: Download the extension files. Either clone the repository or download the ZIP and unzip it somewhere you won't accidentally delete it later. Let's call this magical place the ai-rewriter-extension folder.
Open Chrome's Secret Lair 🚪: Open Google Chrome, type chrome://extensions in your address bar, and hit Enter. Spooooky!
Flip the Super Secret Developer Switch 🕵️‍♀️: Look for a toggle labeled "Developer mode" (usually in the top right corner). Click it. If it's on, you're basically a hacker now. Congrats.
Shove the Folder at Chrome 욱: Click the "Load unpacked" button that magically appeared. A file browser window will pop up.
Point and Shoot 👉: Navigate to and select that ai-rewriter-extension folder (the one containing the manifest.json file, not the zip file!). Click "Select Folder" or "Open".
Bask in the Glory (or fix errors) 🙏: If all went well, you should see the "AI Text Rewriter Pro" extension card appear on the page! If you see angry red errors, you probably messed up step 5. Go back and try again, champ. 💪
Pin for Easy Access: Click the puzzle piece icon in Chrome's toolbar and pin the AI Text Rewriter Pro extension for quick access.

🎉 Ta-da! The extension icon should appear in your Chrome toolbar!

🚀 Quick Start Guide

1. Initial Setup

Click the extension icon or right-click → "Settings"
Get your API key from OpenAI Platform
(Optional) Add custom base URL for OpenAI-compatible APIs
Paste your API key and test the connection
Customize your settings (models, modes, shortcuts)
Save and start rewriting!

2. Using the Extension

Right-Click Method:

Select text in any editable field
Right-click on the selected text
Choose "✨ Rewrite with AI" → pick your desired mode
Watch the magic happen!

Keyboard Shortcuts:

Ctrl+Shift+H - Humanize selected text
Ctrl+Shift+P - Professional tone
Ctrl+Shift+Z - Undo last rewrite

⚙️ Configuration: The Golden Ticket 🔑

Okay, here's the slightly annoying part. This extension needs YOUR OpenAI API Key to actually talk to the AI. Think of it like needing a password to get into the cool AI club.

Why? Because accessing powerful AI models costs money (or at least has usage limits), and OpenAI needs to know who's asking! This extension makes requests directly from your browser using your key.

Where to Snag This Magical Key? 🤔

Go to the OpenAI Platform. You'll need an OpenAI account.
Click "Create new secret key" or "+Create new secret key".
Give your key a name (like "AI Rewriter Extension").
COPY THIS KEY! 📋 It starts with sk- and is a long string of random characters. Treat it like a password. Don't share it publicly!
Important: You won't be able to see this key again, so save it somewhere safe!

Alternative: OpenAI-Compatible APIs

You can also use other compatible APIs:

Vercel AI Gateway: Unified access to multiple AI providers - set base URL to https://ai-gateway.vercel.sh/v1
- Get your API key from Vercel Dashboard
- Use models in provider/model format (e.g., meta/llama-3.1-8b, anthropic/claude-sonnet-4.5)
- Access OpenAI, Anthropic, Meta, Google, Amazon, and more through one endpoint!
LM Studio: Run models locally - set base URL to http://localhost:1234/v1
Ollama: Local models - typically http://localhost:11434/v1
Any OpenAI-compatible endpoint: Just set the custom base URL in settings

Plugging in the Power Cord 🔌

Click the AI Text Rewriter Pro extension icon 🧩 in your Chrome toolbar. This should open the modern Options page.
- Alternatively: Go back to chrome://extensions, find the AI Text Rewriter Pro card, click "Details", then "Extension options". So many clicks!
You'll see a field labeled "OpenAI API Key". It's a password field, so you won't see the key as you paste (oooooh, security! ✨).
PASTE your copied API key into this box.
(Optional) If using a compatible API, enter the base URL in the "Custom Base URL" field.
Click "Test API Key" to verify your connection works. 🧪
Click the glorious "Save Settings" button. 💾
You should see a happy green message saying "Settings saved successfully!". ✅ If you see an angry red message, well... Houston, we have a problem. 🚀 (Did you paste the whole key?).

❗ IMPORTANT NOTE ABOUT YOUR KEY ❗

Keep it Secret, Keep it Safe! 🔒 Don't commit it to public code, don't paste it in random chat rooms. It's linked to your OpenAI account.
Usage Costs $$$! OpenAI charges for API usage based on tokens. Check their pricing page! You are responsible for the usage associated with your key. Start with GPT-4o-mini for cost-effective rewrites. Don't blame us if you rewrite War and Peace and get a bill. 💸
Free Alternative: Use local models with LM Studio or Ollama for completely free, private AI rewriting!

✨ How to Use (The Fun Part!) ✨

Okay, installed? ✅ API key saved? ✅ Ready to rock? ✅ Let's rewrite!

Find a Victim... I Mean, a Text Box 🎯: Go to any website with a text input field (<textarea>, some <input> fields). Think email drafts, comment boxes, social media posts, online notepads... you get the idea.
- Heads Up: This probably won't work on super fancy custom editors like Google Docs or Notion directly, as they do weird things. It definitely won't work on chrome:// pages (like the extensions page itself) for security reasons! Stick to normal web pages (http/https).
Type Your Soon-to-be-Glorious Words ⌨️: Write something. Anything! Pour your heart out, or just type "the quick brown fox jumps over the lazy dog".
Highlight the Chosen Ones ✨: Select the text you want to transform using your mouse or keyboard.
Invoke the Menu! Right-Click Pow! 🖱️💥: Right-click directly on the selected text.
Behold! The Menu! 🤩: Hover over the "✨ Rewrite with AI" option in the context menu that pops up.
Pick Your Mode 🎭: Choose one of the 17 available modes from the sub-menu (Humanize, Professional, Creative, Technical, etc.).
Patience, Grasshopper... 🌱: A sleek notification will appear showing the progress. The extension sends your text and chosen mode to the selected Gemini AI model. Response time depends on text complexity and your selected AI model. 🐹
Witness the Transformation! 🪄: If the AI gods smile upon you, the selected text will be replaced with the rewritten version! 🎉

🤔 Troubleshooting (When Things Go Sideways) 🤔

Yeah, sometimes technology just says "NOPE". 🙅‍♂️ Here's a comprehensive guide:

Common Issues

😭 It's Not Working AT ALL!

API Key: Did you actually save your API key correctly in the options? Is it the right key? Double-check!
Reload Extension: Go to chrome://extensions and click the little refresh icon 🔄 on the AI Text Rewriter Pro card. Sometimes extensions get sleepy.
Reload Page: Try refreshing the webpage (F5) you're trying to use it on.
Check Console (Background): Go to chrome://extensions, find the AI Text Rewriter Pro card, and click the "Service worker" link. Look for RED ERROR MESSAGES in the console window that pops up after you try to use the extension. Copy/paste these if you need help!
Check Console (Page): On the webpage where it's failing, right-click anywhere, select "Inspect", and go to the "Console" tab. Try using the extension again. Any RED ERRORS there?

"API Key not working"

Verify key is correctly copied from the AI provider
Check if your account has API access enabled
Test connection in Settings → General → Test API Key

🚫 Error: Cannot access chrome:// URL

You're trying to use the extension on a Chrome settings page (like chrome://extensions). For security reasons, Chrome blocks extensions from messing with these pages. Use it on a regular http:// or https:// website.

"Cannot rewrite on this page"

Extension only works on regular websites (http/https)
Won't work on Chrome internal pages (chrome://)
Ensure you're in an editable text field

"Text not replacing"

Click in the text field before selecting text
Try refreshing the page and attempting again
Check browser console for detailed error messages

✨ Weird Output (Options, Asterisks *, Emails when you didn't ask?)

The AI can be a bit... creative. We've tried to tell it very sternly in the prompts to JUST give the rewritten text and nothing else (no markdown like *emphasis*, no "Option 1:", etc.).
If you still get weird formatting or unexpected content (like a full email for "Professional Tone"), the AI might be ignoring instructions. We added some cleanup code, but it's not perfect. Prompt engineering is hard! 🤷‍♂️

🚦 Error: Content blocked by API...

The AI's safety filters might have flagged your original text or the requested rewrite (especially possible with "Cheeky"). Try rephrasing your original text or using a different mode.

"Too many requests"

Built-in rate limiting prevents API overuse
Wait 60 seconds and try again
Consider upgrading your plan for higher limits

📉 API Errors (4xx/5xx Status)

400 Bad Request: Often means the model name is wrong or the request format is broken. Try switching AI models in settings.
401 Unauthorized / 403 Forbidden: Almost always an API Key problem. Is it correct? Is it enabled? Does your project have the API enabled?
404 Not Found: The API endpoint URL might be wrong.
429 Too Many Requests: You might be hitting rate limits. Slow down!
500 Internal Server Error: The servers are having a hiccup. Try again later. ☕

Getting Help

Check the browser console (F12) for detailed error messages
Test your API connection in the settings
Try different AI models if one isn't working
Report issues with specific error messages

🔐 Privacy & Security

Your API Key: Stored locally in your browser, never shared
Your Text: Sent directly to the AI provider's servers, not stored by us
Usage Data: Optional analytics stored locally only
No External Tracking: No third-party analytics or tracking
Open Source: Inspect the code to verify privacy practices

📈 Performance Tips

Choose the Right Model:
- Gemini 1.5 Flash: Fastest, most cost-effective

- Gemini 2.0 Flash: Latest features, experimental
Optimize Text Length:
- Keep selections under 2000 characters for best speed

Hey, if you have ideas to make this less buggy or more awesome, or if you found a hilarious bug (like it rewriting everything into pirate speak 🏴‍☠️ - which would be kinda cool, actually), feel free to:

Open an issue on the GitHub repository (if this is on GitHub... otherwise, uh... tell the developer?).
Fork it, fix it, and submit a pull request (again, GitHub stuff).

We appreciate the help making this thing slightly less likely to explode. 🔥

📜 License (The Legal Mumbo Jumbo) 📜

This extension is licensed under the MIT License.

Basically, this means you can do almost whatever you want with this code (use it, copy it, modify it, sell it - though good luck with that!), as long as you include the original copyright and license notice.

BUT, there's NO WARRANTY. If this extension accidentally deletes your masterpiece novel, formats your hard drive, or makes your coffee cold... tough luck. Use at your own risk! 😉
