JMS Chat Lightener

Lighten heavy ChatGPT chats, archive sessions locally, and continue with a memory bridge.

JMS Chat Lightener keeps long ChatGPT conversations fast, light, and recoverable — without losing any context. If you use ChatGPT for coding, research, writing, or long projects, you've felt it: the page gets slow, typing lags, and the browser struggles to keep up. JMS Chat Lightener fixes that directly from your browser toolbar. ——— MAIN FEATURES ——— ⚡ Performance Mode (PRO) Reload-safe mode that prevents old messages from re-rendering after a page reload. ChatGPT stays light even in sessions with hundreds of messages. Set it once — it runs automatically. ✂️ Hard Trim (PRO) Saves older messages to a local archive, then removes them from the active page. The conversation feels new without losing any history. 🌉 Fresh Chat + Full Bridge (PRO) Archives the full session, copies a structured Session Memory Bridge to your clipboard, and opens a clean ChatGPT tab. Continue exactly where you left off — with full context, zero lag. 📋 Copy Latest Bridge Instantly copy your most recent memory bridge and paste it into any new chat to restore context. 📁 Folder Hub (PRO) Save all archives, bridge memory, and chat JSON to a local folder you choose. Everything stays on your device — nothing is uploaded. 🧩 Soft Lock (PRO) Hide older messages without deleting them. Lightweight visual cleanup — restore anytime. ——— PRO PLAN ——— PRO includes Performance Mode, Hard Trim, Fresh Chat + Full Bridge, Soft Lock, Folder Hub, AI Summary, Optimized Bridge, and custom keep-last settings (1–200 messages). One device per license. ——— PRIVACY ——— JMS Chat Lightener is a local browser tool. Your chat content never leaves your device. Archives are saved only to your chosen local folder. The only external connection is to our licensing server to validate your PRO key — no chat data is ever transmitted. This extension is not affiliated with, endorsed by, or connected to OpenAI or ChatGPT.
