LongChat Lite: Fix Slow Long Chat Lag in Claude & Gemini (ChatGPT in Pro)

Long chat lag fix: hides older turns so slow Claude & Gemini chats stay fast. Pro: ChatGPT, AI Studio, Chat Handoff. No tracking.

Long Claude or Gemini thread getting slow? Typing lags, scrolling stutters, and sometimes the tab freezes. That long chat lag happens because the browser keeps every message of a huge thread rendered at once. LongChat Lite is a simple slow chat fix for long threads. It keeps only your most recent turns on the page and hides older ones locally, so a laggy thread feels light again. Nothing is deleted: click "Load more" or "Show all" any time, or switch it off and the full thread is back. WHAT IT DOES • Shows the last 30 messages and hides the rest on your screen only • A slim bar shows how many earlier messages are tucked away, with Load more, Show all and Collapse • Keeps your scroll position when you load older messages • New replies arrive normally; the visible window just slides forward • Toolbar popup with visible/hidden counts and an on/off switch • Self-check: if a site changes its layout, LongChat Lite pauses itself instead of breaking the page FREE AND PRO Free, no account: one site of your choice (Claude or Gemini), last 30 visible. Pro, $5/month or $39/year with a 7-day free trial: • Both free sites together, plus ChatGPT and Google AI Studio (opt-in) • Choose how many stay visible, from 2 to 500 • Prompt navigator to jump to any of your prompts • Search across hidden turns • One-click Markdown export • Chat Handoff: one click copies a handoff of the current conversation (your prompts plus the latest replies, trimmed to a size you set) and opens a fresh one, ready to paste or pasted for you. You still press Send PRIVACY • Runs entirely in your browser. Your conversations are never collected or sent anywhere • Chat Handoff is built locally; the text only goes to your clipboard and the new conversation you open • No analytics, no tracking, no ads, no remote code • Stores only your settings and license status FAQ Will it make the AI answer faster? No. It speeds up the page in your browser (typing, scrolling, rendering), not the model's replies, and it doesn't change usage limits. Does it delete or change my conversations? No. Everything stays in your account. Turn the extension off and everything shows again. Does the AI still see the whole conversation? Yes. Hiding is visual only, so the conversation's context is unchanged. Does the free plan work on ChatGPT or AI Studio? No. Those are part of Pro and stay off until you enable them and allow access to that site. Do search, export and handoff include hidden turns? They cover everything loaded on the page, hidden or not. If a site loads older messages lazily, scroll up or use "Show all" first.
