AI Toolbox 3.0 is the latest version of the browser extension that adds search, folders, and export to ChatGPT, Claude, Gemini, and Grok, and the headline change is that search now runs across all four platforms at once instead of one at a time. It's a free Chrome extension with paid tiers starting at $9.99/month for anyone who outgrows the free limits.
Short answer: AI Toolbox 3.0 is a Chrome extension that adds cross-platform search, folders, and export to ChatGPT, Claude, Gemini, and Grok. The free plan covers 2 folders and 5 search results per query; Premium is $9.99/month or $99 lifetime per platform, and $199 covers all four platforms for life. New in 3.0: unified search, a prompt library, and a Claude artifact vault.
I went straight to the vendor's own site and its Product Hunt launch page rather than trusting secondhand roundups, since a version-number launch is exactly the kind of post that picks up rounded-off or stale numbers fast. When I checked ai-toolbox.co directly, the free-tier limits, the per-platform lifetime pricing, and the four supported platforms all matched what the extension advertises on its own pricing page — the user counts and star rating below are the company's own Chrome Web Store numbers, not an independent audit, and I've flagged them as such.
What you'll need
You need Chrome, Edge, Brave, or another Chromium-based browser — AI Toolbox installs from the Chrome Web Store, with a separate listing for Edge add-ons. No account or card is required for the free tier; it works locally in your browser the moment you install it. Beyond that, you just need an active login to whichever of ChatGPT, Claude, Gemini, or Grok you want it to organize — the extension attaches to those sites directly rather than requiring its own separate account.
Step-by-step: setting up AI Toolbox 3.0
1. Install the extension
Add AI Toolbox from the Chrome Web Store (or the Edge add-ons page if you're on Edge). It installs like any other browser extension — no sign-up screen blocks you from using the free tier right away.
2. Open any of the four supported AI platforms
Visit chatgpt.com, claude.ai, gemini.google.com, or grok.com (or x.com/i/grok). The extension activates automatically on each of these and adds its search and folder panel to the page.
3. Try the new unified search
Press Cmd/Ctrl+Shift+F, or open the search panel, and run one query. This is the 3.0 headline feature: instead of searching just the tab you're on, it searches your history across all four platforms in one pass. The free tier caps this at 5 results per query.
4. Set up your first folders and a saved prompt
Create a folder to group related chats, and save a prompt you use often so you can drop it in later with the "//" shortcut. The free plan caps you at 2 folders and 2 saved prompts, which is enough to test the workflow before deciding if you need more.
5. Decide if you need Premium
If you're bumping into the 5-results or 2-folders ceiling within a week of real use, that's the signal to upgrade rather than a fixed timeline — see the pricing breakdown below for what each tier actually unlocks.
Example prompts and searches you can copy
AI Toolbox isn't a chat interface itself, so "prompts" here means the saved-prompt and search patterns that get the most out of the 3.0 update:
- Save a prompt like "Rewrite this in a more direct, less hedgy tone" under
//toneso it's one keystroke away in any of the four platforms. - Search
budget proposalacross all four platforms at once to find which AI you asked about it last, instead of checking each app's own history separately. - Use a
{{placeholder}}prompt template like "Summarize {{document}} in 3 bullet points for a non-technical reader" so you're filling in one variable instead of retyping the instruction. - On Claude, open the Artifact Vault after a coding session to pull every generated file into one downloadable batch instead of clicking through each artifact.
- Chain a saved prompt with a folder export: run your research prompt, drop the results in a dedicated folder, then export that folder to Markdown at the end of the week.
Common mistakes to avoid
The first mistake is judging the free tier by the 5-search-result cap alone — it's genuinely usable for light lookups, but if you're the type who has 50+ chats spread across two or three AI platforms, you'll hit that ceiling in the first real search. Second, buying the $99 single-platform Premium Lifetime plan when you actually use two or more of the four supported AIs regularly — the $199 All Access Lifetime tier covers all four for barely double the price, and switching later means paying twice. Third, assuming the export formats are interchangeable: only the paid tiers unlock PDF, Markdown, and JSON export, so if you're archiving chats for compliance or documentation reasons, confirm your plan covers the format you actually need before you rely on it. Fourth, skipping the permissions read on install — AI Toolbox markets itself as local-first, meaning your conversation content stays in the browser rather than hitting its servers, but it's worth confirming that claim against the extension's own privacy notes rather than taking a marketing line at face value. Fifth, forgetting the 14-day refund window exists — if a paid tier doesn't fit your workflow, that window is there specifically so you're not stuck.

I confirmed these tiers directly on AI Toolbox’s pricing page on September 6, 2026. Pricing pages for young products move fast, so check the live page before you buy, especially around a version launch — Product Hunt listings for AI Toolbox 3.0 also showed a limited-time launch-week discount code on the All Access Lifetime tier, which won't still be live by the time most people read this.
Tools that make this easier
AI Toolbox is a layer that sits on top of the AI platforms you're already using rather than replacing any of them, so it's worth knowing what each underlying platform does well on its own. My how to use ChatGPT agents guide covers task automation inside ChatGPT itself, which is a useful comparison if you'd rather stay in one assistant than manage a cross-platform layer. If Claude's Artifact Vault is the feature that sold you, how to use Claude AI walks through what Claude generates in the first place. Gemini users should read how to use Gemini AI for the platform-side setup AI Toolbox's Gemini watermark-removal feature depends on. If you're deciding between Grok and ChatGPT as your main platform before you even add an organization layer, Grok vs ChatGPT breaks that down directly. For the broader landscape of AI writing tools this extension organizes output from, see best AI writing tools, and if you're evaluating this as one of several tools for a small team, best AI tool for small business compares it against wider-scope platforms.
My take
The 3.0 update's cross-platform search is the feature that actually matters here — searching four AI histories in one pass instead of four separate tabs is a real time save if you genuinely split your work across ChatGPT, Claude, Gemini, and Grok. What I can't verify from outside a paid account is how the search holds up at real scale, past a few dozen saved chats; the company's own numbers (40,000+ Chrome Web Store users, a 4.6/5 rating) are Chrome Web Store metrics, not an independent benchmark of search quality. The pricing is fair for what it unlocks: $9.99/month is reasonable if you're on one platform daily, and the $199 All Access Lifetime tier is the better deal the moment you use two or more of the four supported AIs, since paying twice for two single-platform lifetime licenses would cost more. Start on the free tier for a week of real use before paying anything — the 5-search-result and 2-folder caps will tell you fast whether you need more.
Frequently Asked Questions
Is AI Toolbox 3.0 free?
Yes, to start. The free plan covers 2 folders, 2 saved prompts, 5 search results per query, and TXT export, with no account or card required. Premium tiers begin at $9.99/month once you need unlimited folders, more export formats, or full prompt chaining.
How long does it take to set up AI Toolbox 3.0?
Installing the extension and using it on your first supported platform takes under two minutes — it's a standard Chrome Web Store install with no separate sign-up. Setting up your first folders and a saved prompt or two adds another five minutes if you're doing it thoughtfully rather than just clicking through.
What's the easiest way to try AI Toolbox 3.0?
Install it, open whichever of ChatGPT, Claude, Gemini, or Grok you use most, and run one cross-platform search before doing anything else. That single search is the clearest way to feel whether the 3.0 update's headline feature is worth paying for once you hit the free tier's 5-result cap.
Should I buy Premium Lifetime or All Access Lifetime?
All Access Lifetime ($199) is the better deal unless you're certain you'll only ever use one of the four supported platforms. A single-platform Premium Lifetime license is $99, so two of them already costs more than covering all four platforms for life under All Access.
Is my chat data safe with AI Toolbox 3.0?
AI Toolbox describes itself as local-first, meaning your actual conversation content is stored and searched in your browser rather than sent to its servers, with only account metadata synced. That's the vendor's own description of its architecture — read the extension's privacy notes yourself before connecting it to anything sensitive, the same way you would for any third-party browser extension with access to your AI chat history.
