“AI Chrome extension” covers two different things: tools that change the inside of ChatGPT, Gemini, Claude or Grok, and sidebars that chat with several models from any page. This guide names the best of each, per platform, and says plainly where a competitor wins.
Free plan, no account. Premium $9.99/month or $99 once per module, $199 once for all four. Any Chromium browser.

Two categories
Most “best AI extension” lists rank these together and end up comparing folders to chat panels. Decide which category you need first; many people run one of each.
Modify the native interface of one AI assistant.
A separate panel that talks to several providers.
Picks by platform
AI Toolbox is one install with a module per platform, so it is the top pick four times, with the free limits stated and the strongest alternative named on each. Every feature listed is in the shipping extension.
ChatGPT, chatgpt.com
The most complete module. ChatGPT has Projects but no folders, no full-text search of message bodies and no bulk export, so this is where the extension adds the most.
Plan: Free: 2 root folders with unlimited subfolders, 5 search results per query, 5 chats per bulk batch, TXT export.
Also worth a look
Gemini, gemini.google.com
Gemini's own search matches titles and recent turns. The module indexes message bodies locally, adds folders, and strips the watermark from generated images.
Plan: Free: 2 root folders, 5 search results per query, TXT export, watermark removal. Bulk actions are Premium.
Also worth a look
Claude, claude.ai
Claude keeps Projects behind paid plans and has no bookmarks, no folders and a title-only search. The module adds all three plus a vault for every artifact Claude generates.
Plan: Free: 2 root folders, 5 search results, bookmarks in 2 conversations, 5 artifacts, TXT export. No default search shortcut on Claude, assign one in chrome://extensions/shortcuts.
Also worth a look
Grok, grok.com and x.com
Grok has a flat history on two surfaces. The module works on grok.com and inside X, and most Grok extensions on the store are export-only.
Plan: Free: 2 root folders, 5 search results, TXT export. Bulk actions are Premium, and Premium is keyed to your X handle.

Side by side
AI Toolbox values are the shipping extension. The other two columns describe the category; where only some tools in it have a feature we mark it partial.

Head-to-head numbers against Superpower, AIPRM, Sider and Monica are on the main comparison. The full list is on the features page.
Multi-AI sidebars
None of these change the native ChatGPT, Gemini, Claude or Grok interface, and none add folders, history search or export. They are a good pick when the job is comparing models or using AI on other websites.
Pricing
Every sidebar and single-platform tool in this guide is subscription-only or free with no upgrade path. AI Toolbox has a free plan with usage caps, Premium per module, and one lifetime price across all four modules. Not an AI subscription: you keep using your own accounts.

FAQ
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 4.7/5 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.
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.
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.
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.
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.
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.
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.
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.
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.
