SynapseClean
Local markdown prompt compactor for AI power-users
Free open-source Chrome extension that compacts messy web copy into clean AI prompts. 100% on-device. Optional Gemini Nano. MIT.
Hey Hunters! 👋 Clean prompts shouldn't require sending data to another cloud.
Like many of you, I spend my day copying documentation, GitHub issues, and long technical blog posts to chat panels like Claude, ChatGPT, or Gemini. Every single time, I felt like I was fighting the layout: copying sidebars, cookie banners, tracking scripts, and menus. Not only does this waste precious context tokens (which gets expensive or hits rate limits quickly), but it also dilutes the quality of the LLM's answers.
I wanted a tool that would clean my clipboard instantly, format it as clean Markdown, and—most importantly—never send my copied text to yet another server.
That’s why I built SynapseClean: 1. Zero-Trust Privacy: It runs entirely inside your browser. No database, no telemetry, no subscription fees. 2. Deterministic Pruning: It uses local DOM traversal to remove common boilerplates. 3. Optional Local AI: If you enable the "Semantic engine," it accesses your Chrome browser's built-in Gemini Nano to turn the page text into a highly structured semantic outline before writing it to your clipboard.
It is 100% free and open-source (MIT licensed). I’d love to hear your thoughts, feature requests, and feedback on the local compactor!
