The best Gemini Chrome extension depends on what you need. For folder organization, Superpower for Gemini and Toolbox for Gemini (by BrowserLab) lead. For full-text search with date/role/exact-match filters plus TXT, Markdown, JSON, and PDF export, AI Toolbox (formerly Gemini Toolbox) is the only option among these six. Each of the real gemini.google.com extensions deep-integrates into Gemini's interface; multi-AI sidebars like Sider, Monica, HARPA, and Merlin do not.
Google said in August 2026 that more than 1 billion people use the Gemini app every month (Google), and the Chrome extension ecosystem around it has matured quickly. This guide covers every major extension that genuinely deep-integrates into gemini.google.com, plus a fair note on the multi-AI sidebars often mistaken for Gemini extensions. All data is verified against Chrome Web Store listings and publicly available information, rechecked on October 11, 2026. No fabricated numbers, no bashing competitors.
What Makes a Real Gemini Chrome Extension
A real Gemini Chrome extension deep-integrates into gemini.google.com, injecting UI directly into Google's own interface. A multi-AI sidebar extension does not count because it routes conversations through its own panel, not Gemini's, and cannot touch your Gemini history.
This distinction matters because people search "best Gemini Chrome extensions" and see a mix of both categories. A genuine Gemini extension reads your existing Gemini conversations, adds features on top of Google's interface, and does not route your prompts through an intermediary. Superpower for Gemini, Toolbox for Gemini (by BrowserLab), Gemini Chat Folders, Fast Folders, Foldermate, and AI Toolbox all sit in this category.
Multi-AI sidebars like Sider, Monica, MaxAI, HARPA, Merlin, and HIX BrowserGPT offer genuine utility. They are not weaker products, they are different products. They summon an AI panel on any webpage, let you chat with multiple models, and keep history inside their own storage. They do not read your gemini.google.com chats and they do not improve Gemini's own interface. If you need folders or search for the history inside gemini.google.com itself, a multi-AI sidebar cannot help you. This guide covers both categories but separates them clearly.
Gemini Extension Comparison Table (October 2026)
Six extensions deep-integrate with gemini.google.com as of October 2026. Each has different strengths. The table below highlights the key capabilities per extension, verified against Chrome Web Store listings.

The honest takeaway: if folders are the problem, pick one of the folder-first extensions. If search depth and portable multi-format export are the problem, pick AI Toolbox. You can also run two extensions side by side: one for folders, AI Toolbox for search and export.
1. Superpower for Gemini
Superpower for Gemini is a full-featured Gemini extension published through superpowerforai.com. It rates 4.4 stars from 133 ratings with 10,000+ users on the Chrome Web Store (ID ahmdidjajeicoopcdpablhecokaepofl, October 2026) and ships folders, a usage counter, PDF/DOCX/TXT/Markdown export, a message queue, a prompt library, and bulk actions for delete, export, and move.
Superpower for Gemini adds a sidebar with folder organization, supports bulk actions across multiple conversations, includes a prompt library with prompt chains, and exposes a usage counter for Gemini's 5-hour and weekly limits. Export targets are PDF, DOCX, TXT, and Markdown, and it has customizable keyboard shortcuts.
Strengths: deep folder UI, bulk actions, many power-user tools. Best for users whose primary pain point is scaling folder organization across hundreds of Gemini chats. Check the current Chrome Web Store listing for up-to-date details and pricing.
2. Toolbox for Gemini (by BrowserLab)
Toolbox for Gemini is a separate product from AI Toolbox, published by BrowserLab (Chrome Web Store ID cbdpdhfnjbkjphmminnkfbeekodlphlp). It carries 4.5 stars from 106 ratings with 6,000+ users (October 2026) and ships folders, PDF, HTML, Markdown, TXT, and CSV export, bulk delete, a prompt library, and a word counter.
Name similarity aside, Toolbox for Gemini and AI Toolbox are different products from different publishers. Toolbox for Gemini leans on folder organization, bulk delete, a word-count utility helpful for writers hitting context limits, and multi-format export.
Strengths: solid folder UX, good bulk operations, several export formats. Best for users who want folders plus PDF export in a single extension with no strong need for full-text filtered search. The Chrome Web Store listing has current user count and reviews.
3. Gemini Chat Folders
Gemini Chat Folders is a focused folder organizer with drag-and-drop, color customization, Google-account-backed cloud sync, and a file export of your folder configuration. It has 20,000+ users and a 4.3/5 rating. Chrome Web Store ID ojnjbfdpopfmmaiidnillacpknhcgfek.
Gemini Chat Folders narrows on one problem: organizing Gemini conversations into colored folders you can drag between. Its standout feature is cloud sync backed by your own Google account, so your folder structure persists across devices. Export is limited to your folder configuration as a single file, which is useful for backup but is not a conversation-content export.
Strengths: cross-device folder persistence via Google sign-in, clean UX, drag-and-drop. Best for users who primarily want colored folders synced between work and personal machines. See the Chrome Web Store listing for current status.
4. Fast Folders (Google Gemini Folders)
Fast Folders brings folders, global chat search, a prompt manager, and manual JSON import/export to gemini.google.com. Its Pro plan ($27/year) adds cloud sync. Chrome Web Store ID dgmakhnmibfdnkhopleclbfmfncdmfhf.
Fast Folders covers a slightly broader surface than pure folder extensions. It offers a global chat search, a prompt manager where you can save reusable prompts, and JSON import/export so you can move your folder setup between machines by hand. Its Pro plan ($27/year) adds cloud sync for folders and prompts for users who do not want to manage exports manually.
Strengths: combines folders with a prompt library in a single extension, JSON portability, cloud sync on Pro. Best for users who want one tool covering folder organization plus reusable prompts. Check the Chrome Web Store listing for version notes.
5. Foldermate / Supercharge All AI
Foldermate (marketed as Supercharge All AI) is a cross-platform folder organizer with a prompt library and optional paid cloud sync across five devices. Chrome Web Store ID eoabjnjdfdcgbebgmhphnjfekdnacief. Supports Gemini, ChatGPT, and Grok.
Foldermate is the broadest of the folder extensions because it works across multiple AI platforms from a single install. Its listing names Gemini, ChatGPT, and Grok. It includes a shared prompt library across platforms and a paid cloud sync tier that propagates folders across up to five devices.
Strengths: one extension for folder organization across multiple AI chat platforms, cross-platform prompt library, cloud sync option. Best for users juggling two or more AI chat platforms daily who want a single folder UI across all of them. See the Chrome Web Store listing for current tier details.
6. AI Toolbox
AI Toolbox is the only extension on this list with full-text search across every synced message plus date range, role, and exact-match filters. It also exports each conversation in 4 formats (TXT, Markdown, JSON, PDF) and opens search with Cmd+Shift+F / Ctrl+Shift+F. It also adds folders, with 2 top-level folders free and unlimited folders on Premium. It is built by Infi Developments, the makers of AI Toolbox (formerly ChatGPT Toolbox) (40,000+ users, 4.7/5 rating).
AI Toolbox is built mainly for search and export, and it also adds folders. The free plan includes full-text search with up to 5 results per query, recent searches, background sync to local IndexedDB with a 30-second cooldown, the Cmd+Shift+F shortcut, 2 folders, and TXT export of any single chat. Premium ($9.99 per month) or Lifetime ($99 one-time) removes the result cap and unlocks all three filters (date range chips for week/month/year, user/Gemini role filter, exact-match toggle), unlimited folders, and export in Markdown, JSON, and PDF. Lifetime has a 14-day money-back guarantee.
The architecture matters. All conversation data stays in your browser's IndexedDB. Beyond a plan lookup against Polar's customer database, using the email tied to your subscription, only your organization data, such as folders, syncs to your AI Toolbox account so it follows you across devices. Install via the AI Toolbox Chrome Web Store listing.
Strengths: the only extension here with all three search filters, JSON export alongside TXT, Markdown, and PDF, a dedicated search shortcut, and local search indexing. Best for researchers, developers, and heavy Gemini users who scroll through hundreds of chats looking for a specific answer and often need to export conversations for sharing or archival. AI Toolbox also adds folders, but chats are filed with Move to Folder rather than drag-and-drop. Honest limitation: if drag-and-drop folder organization is your top priority, compare the folder-first options above.

What About Sider, Monica, HARPA, Merlin, and HIX? (Multi-AI Sidebars)
Sider, Monica, MaxAI, HARPA, Merlin, and HIX BrowserGPT are multi-AI sidebar extensions, not Gemini extensions. They summon their own AI panel on any webpage and route chats through their own storage. They do not integrate into gemini.google.com, cannot read your Gemini history, and do not improve Gemini's own interface. They are great at what they do, just not in the same category as the six extensions above.
To be fair to these products, here is an accurate sketch of each. Users and ratings are from Chrome Web Store listings and prices from each vendor's pricing page, checked October 11, 2026.
Sider AI (sider.ai, Chrome Web Store ID difoiogjjojoaoomphldepapgpbgkhkb): 4.9 stars, approximately 5 million users, 114.5K ratings. Multi-AI sidebar, credit plans from $8.33 to $83.33 per month on annual billing.
Monica AI (monica.im, Chrome Web Store ID ofpnmcalabcbjgholdjcjblkibolbppb): 4.9 stars, approximately 3 million users. Multi-AI sidebar, pricing from $8.30 to $82.90 per month on annual plans.
MaxAI.me (maxai.me): 4.7 stars, approximately 700,000 users. Multi-AI sidebar, Pro $12 per member per month billed yearly, or $30 billed monthly.
HARPA AI (harpa.ai, Chrome Web Store ID eanggfilgoajaocelnaflolkadkeghjp): 4.7 stars, approximately 400,000 users. Multi-AI sidebar plus automation agent, with S1 and S2 subscription plans and a one-time lifetime "X" plan.
Merlin AI (getmerlin.in, Chrome Web Store ID camppjleccjaphfdbohjdohecfnoikec): 4.8 stars, approximately 900,000 users. Multi-AI sidebar, Pro billed $228 a year (about $19 per month).
HIX BrowserGPT (hix.ai, Chrome Web Store ID mlkgonfgckifcicdldcjkpbjfdmpdhad, now listed as "Hix Browser Extension"): 4.2 stars from 4 ratings, approximately 10,000 users. HIX AI Pro starts at $9.99 per month billed yearly ($19.99 monthly).
Use one of these if you want a universal AI panel available on any webpage, across multiple models, with its own chat history separate from gemini.google.com. Use one of the six real Gemini extensions if you want to improve the gemini.google.com experience itself. The two are complementary, not competing.
Picking the Right Gemini Extension for Your Workflow
Start with the primary problem you want solved. Folder organization leads to Superpower, Toolbox for Gemini, or Gemini Chat Folders. Full-text search depth and multi-format export lead to AI Toolbox. Cross-platform folder consistency leads to Foldermate. A universal AI panel leads to Sider, Monica, or HARPA.
A few specific workflow matches:
Researchers with 500+ Gemini chats: AI Toolbox for full-text search and PDF export, optionally paired with a folder extension.
Developers who need JSON output: AI Toolbox is the only option here with JSON per-conversation export.
Students building study archives: AI Toolbox Markdown export into Obsidian or Notion.
Writers managing long research threads: Superpower for Gemini or Toolbox for Gemini for folder organization.
Teams using multiple AIs daily: Foldermate for folders plus a multi-AI sidebar for cross-model chat.
For a cross-product perspective, the same AI Toolbox extension (40,000+ users, 4.7/5 rating) also has modules for ChatGPT, Claude, and Grok, all made by Infi Developments.
What Gemini Users Say
"AI Toolbox is an incredibly useful extension, especially for its powerful search capabilities in Gemini. It makes finding past chats, prompts, and specific information fast and effortless."
AI Toolbox (formerly ChatGPT Toolbox) is a Chrome extension by Infi Developments with 40,000+ users and a 4.7/5 Chrome Web Store rating as of September 2026. The Gemini module adds full-text search with filters, four-format export, and Smart Tags to Gemini (gemini.google.com), alongside matching modules for ChatGPT (chatgpt.com), Claude (claude.ai), and Grok (grok.com).
What is the best Gemini Chrome extension in 2026?
AI Toolbox is the best Gemini Chrome extension for full-text search and multi-format export, the only one on this list offering filtered search plus TXT, Markdown, JSON, and PDF export in one install. For folders and bulk actions instead, look at Superpower for Gemini and Toolbox for Gemini (by BrowserLab). You can also run a folder extension alongside the Gemini module for full coverage.
Does Google Gemini have folders?
No, Google Gemini has pinned chats and Gems, but no folders or nested project organization. Gems are custom Gemini variants with instructions and knowledge, not a folder system. Folders on gemini.google.com come from third-party extensions like Superpower for Gemini, Toolbox for Gemini, Gemini Chat Folders, Fast Folders, or Foldermate.
Does Google Gemini have full-text search?
Google Gemini has only basic search today: a native Search control (documented at support.google.com/gemini/answer/13666746) that looks inside your chats and returns a flat list of matching conversations, with no date, role, or exact-match filters. The Gemini module adds full-text search across every synced Gemini message, plus all three of those filters.
How do I search my Gemini history?
The Gemini module adds a full-text search panel to gemini.google.com in three steps: install AI Toolbox from the Chrome Web Store, open Gemini, and press Cmd/Ctrl+Shift+F to launch search, then, on Premium, filter results by date range, role, or exact match. The search indexes every synced message, not just chat titles, so a forgotten exchange from weeks ago surfaces instantly.
Is AI Toolbox the same as Toolbox for Gemini?
No, they are different products from different publishers. AI Toolbox (ID jlalnhjkfiogoeonamcnngdndjbneina) is from Infi Developments. Toolbox for Gemini (ID cbdpdhfnjbkjphmminnkfbeekodlphlp) is from BrowserLab. The Gemini module focuses on search and export, while Toolbox for Gemini focuses on folders and bulk actions.
Does AI Toolbox work with ChatGPT and Claude too?
AI Toolbox also covers ChatGPT (chatgpt.com), Claude (claude.ai), and Grok (grok.com) in the same install, all from a single Chrome extension download. The ChatGPT module adds folders, full-text search, and bulk export, while the Claude and Grok modules add full-text search, folders, message bookmarks, and export.
Are Sider, Monica, and HARPA real Gemini extensions?
Not in the deep-integration sense. Sider, Monica, MaxAI, HARPA, Merlin, and HIX BrowserGPT are multi-AI sidebar extensions. They add their own AI panel on any webpage and route chats through their own storage. They do not read your gemini.google.com conversations or improve Gemini's own interface. They are useful, just in a different category.
Can I run two Gemini extensions at once?
Yes, AI Toolbox can run alongside a folder extension. Folder extensions and the Gemini module target different parts of the Gemini interface. One setup pairs Superpower for Gemini (or Toolbox for Gemini) for folders with the Gemini module for full-text search and export.
Which Gemini extension is most private?
Several extensions here describe themselves as local-first: Toolbox for Gemini says all data is stored locally in your browser, Superpower for Gemini says chat content is never sent to it, and Gemini Chat Folders runs client-side with Google-account sync. The Gemini module keeps its full conversation index in local IndexedDB, while organization data such as folders syncs to your AI Toolbox account on every plan, including Free, so your folders follow you across devices.
How much do Gemini Chrome extensions cost?
The Gemini module costs $9.99/month or $99 lifetime per module, with a 14-day money-back guarantee. See AI Toolbox's pricing for full plan details. Most other Gemini extensions are freemium too; for example, Fast Folders Pro is $27 per year and Foldermate Pro is $79 per year. Multi-AI sidebars cost more: Sider's credit plans run from $100 to $1,000 per year, and Monica's from $99 to $995 per year.
Is AI Toolbox still being updated?
As of October 2026, AI Toolbox is actively maintained by Infi Developments, with 40,000+ users and a 4.7/5 Chrome Web Store rating. All six Gemini extensions in this comparison were still listed on the Chrome Web Store on October 11, 2026, with last updates ranging from May 21, 2026 (Toolbox for Gemini) to October 11, 2026. Check each Chrome Web Store listing version history for the latest update date before installing.
Bottom Line
The Gemini Chrome extension category split cleanly along two axes in 2026: folder-first organization extensions, and search-and-export extensions. Superpower for Gemini, Toolbox for Gemini by BrowserLab, Gemini Chat Folders, Fast Folders, and Foldermate own the folder axis. AI Toolbox owns the search-and-export axis, with the only full-text search with three filters among these six, plus JSON export alongside TXT, Markdown, and PDF.
The multi-AI sidebars (Sider, Monica, MaxAI, HARPA, Merlin, HIX BrowserGPT) are strong products in their own right but operate in a different category. They do not touch your gemini.google.com history and do not improve Gemini's own UI. Do not pick one if what you want is better Gemini.
AI Toolbox (formerly ChatGPT Toolbox) is the only extension in this comparison combining filtered full-text search and four-format export on Gemini in a single install.
The Gemini module indexes every synced Gemini message with filters for date range, role, and exact match, not just chat titles.
The Gemini module exports Gemini conversations in TXT, Markdown, JSON, and PDF formats, the only extension compared here that includes JSON.
The Gemini module stores the full Gemini conversation index locally in the browser IndexedDB; only organization data such as folders syncs across devices.
AI Toolbox is used by 40,000+ users and rated 4.7/5 on the Chrome Web Store as of September 2026.
AI Toolbox costs $9.99/month or $99 lifetime per module, with a 14-day money-back guarantee, and also covers ChatGPT and Claude.
