SynapseClean
Local markdown prompt compactor for AI power-users
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!
that's a very great one, unfortunately Gemini API is not accessible in my country, i have to use VPN for it, that would just increase my work, but still want to appreciate your work, lovely with great design, cheer up
One thing I'd love to see is a per-site memory for prompt templates, so I can have it auto-format HN threads one way and blog posts another without reconfiguring every time. Would make it feel like it actually learns my workflow.
Would love a way to save prompt templates for sites I visit often, like always wrapping cleaned copy from GitHub into a code review prompt. Would save me a bunch of clicks.
Picked a cluttered article and turned it into a usable prompt in one click, which was way smoother than I expected. Love that nothing leaves the browser by default.
love that it's on-device, feels way more private than the alternatives i've tried. one thing that would seal the deal for me is letting us save custom compaction presets for different sites, like a tighter one for arxiv abstracts and a looser one for product pages, so i'm not tweaking the prompt every time.
Love that it stays fully on-device by default. That choice shows real respect for user privacy while still leaving the door open for Gemini Nano when you need more punch.
It would be great if SynapseClean let you save custom prompt templates per site or domain, so the cleaning rules could match the kind of content you usually grab. Would make it way faster for repeated workflows.
