What is the best Chrome extension for Claude?
AI Toolbox (formerly ChatGPT Toolbox) is the most complete Chrome extension for claude.ai in 2026, with 40,000+ users and a 4.6/5 Chrome Web Store rating. Its Claude module adds full-text search with exact match, folders with unlimited subfolders, message bookmarks, an Artifact Vault, Smart Tags, Context Mentions, a Context Meter, a prompt library with chains, and export as TXT, Markdown, JSON or PDF. The free plan needs no credit card.
Is the AI Toolbox Claude module free?
Yes, with no time limit. The free plan includes 5 search results per query, 2 root folders with unlimited subfolders, bookmarks in 2 conversations, Smart Tags on 50 chats, 5 saved artifacts, 3 Context Mentions a day, the Context Meter and single-chat TXT export. Premium is $9.99 per month or $99 once for a Lifetime licence and removes the limits, adding bulk actions and Markdown, JSON and PDF export.
Does AI Toolbox work with Claude Pro, Max and Team?
Yes. It works with every Claude plan, including free, because it sits on the claude.ai interface rather than the model. Your Claude subscription and your AI Toolbox plan are independent.
How is this different from Claude for Chrome, Anthropic's browser agent?
Claude for Chrome is Anthropic's agent that browses websites and completes tasks for you. AI Toolbox does not automate browsing; it organises and searches your own conversations on claude.ai and gives you folders, bookmarks, artifacts, prompts and export. The two can be installed side by side.
Does AI Toolbox search Claude conversations I had before installing it?
Yes. On first run the Claude module indexes your existing conversations into a local database in your browser, so search, Smart Tags and the Artifact Vault cover the history you already have. New conversations are indexed as you create them.
Does AI Toolbox send my Claude conversations anywhere?
No. Conversation content is stored and searched locally in your browser and is never stored on our servers. Only what you build in the extension (folder names, bookmarks, prompts, tags, settings) syncs to your account, encrypted at rest. PDF export renders on our server and returns the file without keeping a copy. AI Toolbox is GDPR compliant and passed Chrome Web Store security review.
Is there a keyboard shortcut for search on Claude?
Not by default on Claude. You can assign one in Chrome at chrome://extensions/shortcuts. The cross-platform search that looks across ChatGPT, Gemini, Claude and Grok at once has its own global shortcut, Ctrl+Shift+Period (Cmd+Shift+Period on Mac), once you switch it on.
Which languages does the Claude module support?
The extension interface is available in 10+ languages, including Arabic and Hebrew with right-to-left layout. Search, folders, bookmarks and export work in any language Claude does.
Which browsers can I use it on?
Chrome, Edge, Brave, Opera, Arc and any other Chromium-based browser, from a single Chrome Web Store install. Firefox is not supported.
