Capture context from supported AI chats
The privacy policy says the extension reads AI conversation text from the DOM of supported sites when the user clicks Capture, rather than collecting it passively.
Prompt Bridge
Freemium
Prompt Bridge is a Chrome extension that helps users carry AI conversation context across supported AI platforms, so they can continue threads without starting over.
What is Prompt Bridge?
Prompt Bridge is a Chrome extension that helps users move AI conversation context between supported chat platforms. Its core purpose is to avoid restarting a thread when switching between tools or continuing work later.
The site describes the product as free, with no sign-up required, and compatible with Chrome, Edge, and Brave. Its privacy policy says the extension works locally on the device and only sends text to a third-party AI provider when the user explicitly triggers a summarization action.
What can Prompt Bridge do?
Store conversation threads locally
Captured threads are stored in browser IndexedDB on the user’s device, which keeps conversation context available for later reuse without relying on a publisher server.
Summarize through configured AI providers
The extension can send text to a provider the user has configured for summarization, with listed options including OpenAI, Anthropic, Google Gemini, DeepSeek, and xAI.
Transfer context into another chat
The privacy policy states that user data is used to support the user-facing feature of injecting captured context into another supported AI chat.
Keep API keys on the device
API keys for configured providers are stored encrypted at rest in chrome.storage.local, with the encryption key generated locally on first install.
Work without account sign-up
The homepage states that Prompt Bridge is free and does not require sign-up, which lowers the setup overhead for individual users.
Use Cases
“Continue a long research thread”
A user can capture a conversation from one AI chat and move that context into another platform instead of re-explaining the full background and constraints.
“Switch between different model strengths”
Someone comparing responses from different AI providers can preserve the same prompt history while moving the work into another supported chat interface.
“Resume work after closing a browser session”
Because threads are stored locally, users can return later, retrieve the saved context, and continue from the same point without rebuilding the conversation.
“Summarize before handing off a prompt”
A user can trigger summarization through a configured provider to condense a longer exchange before injecting that context into a new chat.
“Manage personal prompt archives”
The local storage model and export/delete controls make the extension suitable for users who want to keep or clear their own AI conversation history on demand.
