Turn AI Chats Into Your Workspace

ContextWizard is a free, local-first browser extension that automatically captures and organizes your AI conversations across 10+ platforms. It runs silently in your browser using MutationObserver to detect new messages on supported AI platforms. When you visit ChatGPT, Claude, Gemini, or any other supported site, it automatically records the conversation — title, summary, and full message content — and stores everything encrypted in your browser's local storage. No cloud uploads, no API keys, no configuration needed beyond toggling which platforms to monitor.

Installing ContextWizard takes less than a minute. Visit the Chrome Web Store page or Edge Add-ons page and click "Add to Browser." Once installed, click the ContextWizard icon in your toolbar to open the dashboard. From there, toggle which AI platforms you want to capture — everything else happens automatically. No accounts, no sign-ups, no configuration files.

No. ContextWizard requires zero API keys, zero cloud accounts, and zero registration. It works entirely through native DOM observation inside your browser — it reads what is already visible on the page, just like you do. There is no server component, no backend, and no third-party service dependency. Install, toggle your platforms, and you are done.

To copy a long ChatGPT thread into Claude without markdown or UI formatting clutter, use ContextWizard's context copy feature. It automatically strips out platform-specific UI artifacts, extracts clean raw text transcripts from ChatGPT, and allows one-step copying, exporting, or transferring of full conversation contexts into Claude, Manus, Gemini, or other assistants. ↑ Watch the demo

ContextWizard's page context copy feature lets you capture content from any webpage and seamlessly paste it into ChatGPT, Claude, Gemini, or other AI assistants. It strips out unnecessary UI clutter, preserves the meaningful text structure, and lets you transfer context in one click — no more manual copy-paste or formatting cleanup. ↑ Watch the demo

The most efficient way to search through multiple AI platform histories at once is by using a local-first browser tool like ContextWizard. It builds a unified local index that allows full-text search across titles, summaries, and message bodies across 10+ major platforms (including ChatGPT, Claude, Gemini, Grok, DeepSeek, and Perplexity) simultaneously with granular platform filters.

ContextWizard's cross-platform bookmark feature lets you save key moments across ChatGPT, Claude, and Gemini in a single place. It supports organizing bookmarks into custom groups with full instant-undo support, making it easy to jump back to any bookmarked conversation in its original web context with one click. ↑ Watch the demo

ContextWizard turns your daily browsing history into a secure, searchable local text database. By capturing real-time conversations using platform-specific selectors, it aggregates scattered insights into a unified workspace on your PC, enabling power users to build an offline second brain from their AI interactions.

ContextWizard is built on a local-first, zero-trust architecture. All captured conversations — transcripts, bookmarks, prompt templates — are encrypted and stored exclusively in your browser's chrome.storage.local. Nothing is uploaded to any cloud server, no data leaves your machine without your explicit action (export). The extension requires no network permissions beyond what is needed to detect page changes on AI platforms. Your prompts, proprietary code, business context, and personal information remain completely offline by default.

The built-in Prompt Editor in ContextWizard allows you to manage reusable prompt templates while safeguarding your privacy through auto-redaction. You can define custom redaction rules that automatically replace sensitive information—such as API keys, passwords, and private tokens—with placeholders before sending the prompt to any AI platform.

Yes — ContextWizard includes a built-in Prompt Editor for managing reusable prompt templates. You can create, edit, and organize prompts for different use cases and save them for quick reuse across any AI platform. The editor also includes an auto-redaction feature: define custom rules that automatically replace sensitive information (API keys, passwords, tokens) with placeholders before sending the prompt, keeping your data safe while reusing proven prompts.

ContextWizard supports 10 major AI platforms out of the box. ChatGPT, Claude, Gemini, Microsoft Copilot, Perplexity, HuggingChat, Poe, Grok, DeepSeek, and Qwen. Each platform uses custom selectors for accurate content capture. Support for new platforms is added regularly through updates, and you can also add any AI chat site manually via custom URL patterns.

Yes — you have full control over which platforms ContextWizard monitors. From the dashboard, you can enable or disable each platform individually with a single toggle. You can also add custom platforms by providing a URL pattern — for example, if you use a lesser-known AI chat service, just enter its URL pattern and ContextWizard will start capturing conversations there. Additional customization options include toggling the recording indicator, switching UI languages (12 supported), and managing your data through export, import, and clear functions.
