## Description

<strong>Switch AI tools. Not your progress.</strong>

Moving between ChatGPT, Claude, Gemini, Perplexity, or DeepSeek usually means starting over — re-explaining your project, re-stating your requirements, losing every decision you made.

<strong>ContextBridge fixes that.</strong>

Capture your conversation from any AI tool, compress it into a structured <strong>Context Card</strong>, and inject it into another AI assistant — so you continue exactly where you left off.

How It Works

<strong>1. Capture</strong>
Click once to capture your current AI conversation. ContextBridge extracts your goals, decisions, constraints, requirements, and key discussion points.

<strong>2. Compress</strong>
Using your own Mistral API key, ContextBridge converts long conversations into a compact, structured Context Card — only what matters, nothing that doesn't.

<strong>3. Inject</strong>
Open any supported AI tool, inject the Context Card, and continue without missing a beat.

What's in a Context Card?

Each Context Card preserves:
<ul><li><strong>Goal</strong> — the primary objective of the conversation</li><li><strong>Decisions</strong> — important conclusions and choices made</li><li><strong>Constraints</strong> — requirements and limitations that must carry forward</li><li><strong>Key Discussion Points</strong> — the most important ideas and takeaways</li></ul>
<strong>Supported AI Platforms</strong>

Works across all major AI assistants, including:
<ul><li>ChatGPT</li><li>Claude</li><li>Gemini</li><li>Perplexity</li><li>DeepSeek</li><li>Microsoft Copilot</li><li>Grok</li><li>Poe</li><li>Le Chat</li></ul>
Example Workflows

<strong>Research → Development</strong>
Research a topic in Perplexity, then continue implementation in Claude — with full context intact.

<strong>Planning → Execution</strong>
Build a project plan in ChatGPT, then hand it off to Gemini without re-explaining a single requirement.

<strong>Model Comparison</strong>
Move the same conversation between Claude and ChatGPT to compare outputs side-by-side.

<ul><li>No account required</li><li>No activity tracking</li><li>No analytics or telemetry</li><li>All data stored locally in your browser</li><li>Your API key stays on your device</li><li>You use your own Mistral API key — your data never passes through our servers</li></ul>
Perfect For
<ul><li><strong>Developers</strong> — move debugging sessions, architecture discussions, and coding tasks between AI tools</li><li><strong>Founders</strong> — transfer product planning, market research, and business discussions</li><li><strong>Students</strong> — continue research and learning conversations across different AI assistants</li><li><strong>Writers</strong> — move drafts, outlines, and creative projects between models</li><li><strong>AI Power Users</strong> — use the best AI model for each task without losing context</li></ul><blockquote><em>Your AI conversations should be portable.
