Prompt Bridge

Prompt Bridge is a free Chrome browser extension built by Atharv-110 that solves the context-switching problem when working across multiple AI platforms. It lets users capture full conversations from one AI tool and inject them into another with a single click, keeping all data stored locally on the device with no cloud sync or sign-up required.

What It Is

Prompt Bridge is a browser extension in the productivity and AI workflow category. Its core job is to make AI context portable — when you switch from ChatGPT to Claude, or from Gemini to Grok, you no longer need to manually copy, paste, or re-explain your conversation history. The extension captures, compresses, and re-injects conversation context across supported platforms automatically.

Supported Platforms and Browsers

Prompt Bridge works on Chrome, Edge, and Brave browsers. It supports the following AI platforms out of the box:

• ChatGPT (OpenAI)
• Claude (Anthropic)
• Gemini (Google)
• Grok (xAI)
• DeepSeek
• Microsoft Copilot

The extension auto-detects the active AI platform when you switch tabs, requiring zero manual reconfiguration.

How Context Transfer Works

The workflow has three steps:

1. One-Click Capture — Save any full conversation from a supported AI platform directly from the extension popup.
2. Smart Compression — An AI-powered summarization step condenses long conversations into tight summaries, which the product page notes can cut token costs dramatically.
3. Instant Bridge / Inject — With one click, the saved (and optionally compressed) context is injected into the input box of whichever AI platform is currently active.

Privacy Architecture

A central design principle of Prompt Bridge is that no data leaves the user's device. There are no servers, no cloud storage, and no account required. All captured conversations and compressed summaries are stored in local browser storage. The product page highlights this as a key differentiator for privacy-conscious users.

Current Status

Prompt Bridge is live on the Chrome Web Store and is listed as free with no sign-up required. The project is open on GitHub under the Atharv-110 account. A demo video is noted on the homepage as "coming soon," indicating the product is in an early but publicly available stage.
