ContextCapsule

Compress ChatGPT, Claude, DeepSeek, Grok, & Gemini conversations into token-efficient context briefings.

ContextCapsule is the ultimate tool for developers and power users who frequently switch between different AI models and chat sessions. Manually rebuilding context from massive conversation histories wastes time and eats up your LLM token limits. ContextCapsule solves this by instantly analyzing and compressing your current AI conversation into a dense, structured briefing that is highly optimized for a fresh AI session to understand. Stop over-explaining and pasting huge chat transcripts. With one click, ContextCapsule extracts the conversation directly from the page and uses the Gemini API to generate an AI-to-AI optimized <CONTEXT_CAPSULE> detailing the core objective, tech stack, current state, known constraints, critical code snippets, and immediate next steps. 🚀 Key Features: 5 Supported Platforms: Works seamlessly on ChatGPT (chatgpt.com), Claude (claude.ai), DeepSeek (chat.deepseek.com), Grok (grok.com / x.com/grok), and Gemini (gemini.google.com). 1-Click Extraction: Bypasses manual copying and server-side scraping blockers by automatically extracting the conversation directly from the browser DOM. This means whatever you see on your screen is what gets summarized! 90%+ Token Reduction: Shrinks sprawling, multi-thousand token chats down into focused, 250-500 token briefings. Save your context window limits for what actually matters! AI-Optimized Output: The resulting summary is intentionally written in a dense, telegraphic style designed specifically for LLMs to read, eliminating conversational filler and fluff. Privacy First, Zero Storage: Your data stays private. The application is completely stateless. It extracts the conversation, processes it entirely in memory during transit, and returns the summary. Absolutely ZERO bytes of your conversation history or code are ever saved to a database. 🛠 How it works: Navigate to any active conversation or public share link on a supported AI platform. Click the ContextCapsule extension icon in your browser toolbar. Click "Summarize Conversation". Review the token savings and click "Copy Briefing". Paste the briefing into a new chat session (even on a different platform!) to instantly port your context over and continue working without missing a beat. Transform the way you port context between AI sessions and stop repeating yourself today! (Note: Free usage is currently capped at 15 summarizations per day per IP address to ensure fair usage and prevent abuse).
