Local-only, privacy-first browser extension that fixes UI lag in long conversations. --- 🤔 Why LightSession? Long ChatGPT threads are brutal for the browser: the UI keeps every message in the DOM and the tab slowly turns into molasses — scroll becomes choppy, typing lags, devtools crawl. LightSession fixes that by intercepting API responses and trimming conversation data before React renders it, keeping the actual conversation intact on OpenAI's side. - Fixes UI lag in long chats - Keeps model context intact (only the DOM is trimmed) - 100% local – no servers, no analytics, no tracking Built after too many coding sessions where a single ChatGPT tab would start eating CPU and turn the browser into a slideshow. --- 🎯 Who is this for? - People who keep very long ChatGPT threads (100+ messages) - Developers who use ChatGPT for debugging, code reviews, or long refactors - Anyone whose ChatGPT tab becomes sluggish after a while --- ✨ Features Performance - Fetch Proxy – intercepts API responses and trims JSON before React renders (no flash of untrimmed content) - Message-based counting – counts conversation messages (aggregated by role), not individual nodes, for accurate limits - Automatic trimming – keeps only the last N messages visible (configurable range: 1–100) - Ultra Lean Mode (Experimental) – aggressive CSS optimizations: kills animations, applies containment User experience - Co","default_branch":null,"files":null,"tree":[],"storefront":"/r/11me","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/11me/light-session/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
