AI Chat Speed Booster 作者： Noah Thiering

Long AI chat conversations slow your browser to a crawl. AI Chat Speed Booster fixes this by only rendering the most recent messages and loading the rest on demand. It's also fully open source and actively maintained https://github.com/Noah4ever/ai-chat-speed-booster.

Works with: ChatGPT, Claude, Gemini

How it works:
• Only the last 3 messages are shown when you open a conversation (configurable)
• Caches up to 5 trimmed conversation responses with an LRU cache for faster switching between recent conversations
• Older messages are hidden before the browser renders them, so there's zero layout cost
• A "Load More" button appears at the top. Click it to reveal older messages in batches (also has Auto Load to automatically reveal older messages when scrolling to the top)
• New messages follow FIFO: when a new message arrives, the oldest visible one is hidden automatically
• Reduces the amount of chat data before rendering for even faster load times
• Track weekly requests to manage subscriptions better

Settings:
• Visible messages: how many messages to show at a time (default: 3)
• Batch size: how many messages to reveal per "Load More" click (default: 3)
• Fast Mode: intercept and trim chat data before it reaches the renderer
• Hide old messages: toggle DOM hiding on or off (useful if a site has its own virtualization)
• Auto Load: automatically reveal older messages when scrolling to the top
• Status indicator: show/hide and reposition the floating in-page badge
• Weekly request limit: set a threshold to help monitor subscription usage
• Theme: light or dark
• Enable/disable toggle: turn the extension on or off without uninstalling

Privacy:
• No message content is ever read, stored, or transmitted
• No analytics, telemetry, or external network requests
• All settings stay in your browser's local storage
• Open source
