What is the best Chrome extension for AI chat?
It depends on the job. To add folders, full-text search, bookmarks and export inside ChatGPT, Gemini, Claude or Grok, AI Toolbox (formerly ChatGPT Toolbox) is the only extension with a dedicated module for all four in one install, rated 4.6/5 by 40,000+ Chrome Web Store users. For a shared prompt-template library on ChatGPT, AIPRM. For chatting with several models from any webpage, a multi-AI sidebar like Sider or Monica.
What is the difference between a deep-integration extension and a multi-AI sidebar?
A deep-integration extension injects features into the native interface of one AI assistant: folders in the ChatGPT sidebar, bookmarks on Claude messages, watermark removal on Gemini images. A multi-AI sidebar is a separate panel that sends your prompt to several providers and shows the answers in its own UI. Sidebars cannot change chatgpt.com, gemini.google.com or claude.ai, and deep-integration tools do not run on other websites, so the two categories complement each other.
Is there one Chrome extension that works with ChatGPT, Gemini, Claude and Grok?
Yes. AI Toolbox (formerly ChatGPT Toolbox) is one install with four modules, one each for chatgpt.com, gemini.google.com, claude.ai, and grok.com plus Grok inside x.com. Each module is toggled from the extension popup. Folders, search, bookmarks, prompts, chains and export behave the same way on every platform, with a few platform-specific extras such as the media gallery on ChatGPT, watermark removal on Gemini and the Artifact Vault on Claude.
Does ChatGPT have folders built in?
No. ChatGPT has Projects, which group chats with files and instructions, but no folder tree and no subfolders. The AI Toolbox ChatGPT module adds nested folders to the sidebar, filled by searching for a chat name rather than dragging. The free plan includes 2 root folders with unlimited subfolders; Premium removes the cap.
Which Gemini extension removes the image watermark?
The AI Toolbox Gemini module removes the AI watermark from images generated on gemini.google.com automatically, as soon as the image renders, and the feature is free. Other Gemini extensions we compared, including Superpower for Gemini, Chat Lens and Gemini Exporter, do not include it.
What does the Claude module add that Claude does not have?
Folders and subfolders on every Claude plan, message bookmarks with scroll-to highlight, exact-match full-text search of message bodies, an Artifact Vault that collects every artifact Claude generates, smart tags, @@ context mentions, a context window meter, prompts, chains and export as TXT, Markdown, JSON or PDF. Claude natively offers Projects on paid plans and a title-level search only.
Can I run AI Toolbox together with Sider, Monica or AIPRM?
Yes. AI Toolbox only runs on the AI platforms' own domains and adds controls to their interfaces; sidebars live in their own panel. Two extensions that both rewrite the ChatGPT sidebar, such as AI Toolbox and Superpower ChatGPT, can overlap visually, so most people keep one of those and pair it with a sidebar or a prompt tool.
How much does AI Toolbox cost?
There is a free plan on all four modules with usage caps, no account required. Premium is $9.99/month or $99 one-time per module. All Access Lifetime is $199 one-time for ChatGPT, Gemini, Claude and Grok plus every future module, $197 less than four single Lifetimes. A 14-day money-back guarantee applies to a first purchase; renewals are not refundable. It is not an AI subscription: you keep using your own ChatGPT, Gemini, Claude and Grok accounts.
Which browsers does AI Toolbox support?
Any Chromium browser that installs from the Chrome Web Store: Chrome, Microsoft Edge, Brave, Arc, Opera and Vivaldi. There is no Firefox or Safari version.
