About 9AnimeToSimkl

**Never manually track anime episodes again.** 9AnimeToSimkl bridges the gap between 9animetv.to and Simkl, automatically syncing your watch history as you watch. No buttons to click, no forms to fill—just pure automation. **What makes this different?** Most anime trackers require you to manually search for shows, select episodes, and click "mark as watched" after every episode. That's tedious. This extension does all of that in the background while you focus on what matters: watching anime. **How it works:** The moment you start watching an episode on 9animetv.to, the extension springs into action. It identifies the anime, determines which episode you're watching, finds it on Simkl, and marks it as watched—all in seconds. Your Simkl profile stays perfectly synced without any effort from you. **Key Features:** AUTOMATIC DETECTION The extension monitors your 9animetv.to activity and detects when you visit an episode page. No manual input required. SMART EPISODE MAPPING 9anime uses internal episode IDs that don't match standard episode numbers. The extension fetches the complete episode list for each anime and accurately maps IDs to the correct episode numbers. INSTANT SYNC Episodes are marked as watched on Simkl within seconds of detection. Your watch history is always current. PRIVACY FIRST Your credentials stay on your device. The extension only communicates with Simkl's official API—no third-party servers, no data collection, no tracking. PERSISTENT AUTHENTICATION Set it up once and forget about it. Your authentication persists across browser restarts and system reboots. You'll never need to re-authenticate unless you choose to disconnect. LIGHTWEIGHT & EFFICIENT Minimal resource usage. The extension only activates when you're on 9animetv.to, and uses Chrome's built-in APIs for maximum efficiency. **Perfect for:** - Anime fans who watch on 9animetv.to and track on Simkl - Anyone tired of manually updating their watch lists - Users who want seamless integration between streaming and tracking platforms - People who value automation and efficiency **Setup takes 5 minutes:** 1. Create a free Simkl developer app to get your Client ID (one-time setup) 2. Paste the Client ID into the extension settings 3. Connect your Simkl account using the secure PIN flow 4. Done. The extension handles everything from here. **Technical transparency:** This extension uses Simkl's official OAuth PIN flow for authentication. Your access token is stored locally in Chrome's encrypted storage and never transmitted to any third party. The extension requires permissions for 9animetv.to (to detect episodes) and api.simkl.com (to sync your history). That's it. **Open source:** The complete source code is available on GitHub. You can review exactly what the extension does, how it works, and verify that it respects your privacy. **Support:** Having issues? Check the troubleshooting guide in the extension settings or visit the GitHub repository for detailed documentation and support. [ https://github.com/OrosmanAS/9AnimeToSimkl/tree/main ]
