Make sure Developer Mode is enabled. Check for errors in the extension card on chrome://extensions. If you see "manifest" errors, ensure you selected the correct folder (the one with manifest.json inside).
1. Is Ollama running? Check with ollama list in terminal.
2. Did you set OLLAMA_ORIGINS=*?
3. Is the URL correct? Default: http://127.0.0.1:11434
4. Try http://localhost:11434 instead.
Some extensions use the Side Panel (SideScribe, Mail Craft, CodePeek, Page Chat). Click the extension icon in the toolbar. If nothing happens, right-click the icon and check if "Open Side Panel" is available.
Extensions like Textbaustein and Sprach Buddy inject scripts into web pages. They won't work on chrome:// pages or the Chrome Web Store. Try on a regular website like google.com.
Double-check your key is correct and has credits. OpenAI requires a payment method. Anthropic requires a funded account. Gemini has a free tier but may require billing setup.
No! The first 8 extensions work completely offline without any AI. The AI extensions have built-in fallbacks (SideScribe, Clip Genius) or clearly show when AI is needed.
Yes. All data stays in your browser's local storage. Nothing is sent to external servers unless you explicitly configure a cloud AI provider. With Ollama, even AI processing stays on your computer.
Absolutely. Each extension is independent. You can install all 13 and they won't interfere with each other.
Yes! They work in Microsoft Edge, Brave, Opera, Vivaldi, and any Chromium-based browser that supports Manifest V3.
Replace the files in the extension folder, then go to chrome://extensions and click the refresh icon on the extension card.
