SynapseClean

SynapseClean is a free, open-source Chrome extension that transforms cluttered web content into concise, usable text on-device. Key features include: • Messy web copy into clean text • 100% on-device processing • Optional Gemini Nano semantic refinement • No accounts, telemetry, or backend required This tool is designed for power-users and researchers who frequently copy web pages for use with various text processors. It eliminates navigation chrome, cookie banners, ads, and invisible formatting, which often waste context windows and premium message quotas in other applications. By intercepting clipboard operations, SynapseClean ensures that only pertinent information is passed on, saving time and resources. The approach focuses on local processing, meaning selections are prepared and optionally refined directly on your device. It performs a light rule-based cleaning, converting HTML to Markdown and stripping boilerplate, and can further refine the output with semantic processing if Gemini Nano is enabled and available. The tool prioritizes user privacy and control, offering a completely client-side solution with no data ever sent to the cloud. SynapseClean is ideal for anyone who needs to quickly get clean, structured text from web pages for research, content creation, or data entry, without the overhead of cloud services or complex software. It's a robust solution for maintaining focus and efficiency when working with web-sourced information.
