One Extension for Both ChatGPT and Claude: What Actually Works (2026)

Is there one extension that works for both ChatGPT and Claude?
Yes — but the list is much shorter than you’d expect. Out of the dozens of “AI chat organizer” extensions on the Chrome Web Store, only a handful genuinely support both chatgpt.com and claude.ai: Easy Folders, ChatGPT Folders by Wimeki, and our own NorthLab Folders. Most of the big names, including Superpower ChatGPT, work on OpenAI’s site only.
Full disclosure before we go any further: we make NorthLab Folders, so we’re a participant in this comparison, not a neutral referee. What we can promise is the same standard we applied in our roundup of the best ChatGPT folder extensions: checkable facts, published privacy policies, and honest notes on where our own product falls short.
If you use both assistants daily — ChatGPT for one kind of work, Claude for another — this post covers which tools actually span both, what “supports both platforms” should mean in practice, and how to judge the privacy trade-offs of giving one extension access to two AI accounts.
Which kind of “works with both” extension do you actually need?
“An extension for both ChatGPT and Claude” describes four different categories of tool, and the right pick depends entirely on which problem you’re solving. Chat organizers (folders, pins, search, export) are what this post compares — NorthLab Folders, Easy Folders, and ChatGPT Folders by Wimeki are the genuine dual-platform options there. Side-by-side comparison tools like ChatHub send one prompt to several models at once — a different job entirely. All-in-one AI sidebars like Sider, Merlin, and Monica put an AI assistant on every webpage, which means they route your prompts through their own servers and request browser-wide permissions. And prompt managers focus on saving and reusing prompt libraries across platforms.
If your problem is a chaotic sidebar and un-findable old conversations, you want a dedicated organizer — the narrower scope is a feature, because it comes with narrower permissions. If you want to compare model outputs or summon AI on arbitrary websites, an organizer isn’t the tool, and we’d rather say that plainly than win an install that doesn’t fit.
Why running two separate organizers doesn’t work
The obvious workaround is to install one folder extension for ChatGPT and a different one for Claude. I tried this before building our own tool, and it fails for a mundane reason: you end up maintaining two incompatible organizational systems for what is really one body of work.
Your projects don’t split cleanly along platform lines. A typical week for me involves debugging in Claude, drafting in ChatGPT, and research spread across both. With two organizers you get two folder trees with different names, two search boxes that each see only half your history, and two export formats. The mental overhead of remembering which AI you asked becomes its own problem — and that’s precisely the problem folders were supposed to solve.
There’s also a quieter cost: every additional extension with host access to an AI site is one more party you have to trust with visibility into your conversations. Two organizers means two privacy policies to audit, two permission grants, and two developers who could push a bad update. One well-scoped extension is a smaller attack surface than two.
Which extensions actually support both platforms?
Three folder extensions offer real, first-class support for both ChatGPT and Claude as of July 2026. Here’s how they compare on the criteria that matter — platform coverage, privacy architecture, and what the free tier actually gives you:
| Extension | ChatGPT | Claude | Safari | Local-first | Free tier | Price |
|---|---|---|---|---|---|---|
| Easy Folders | Yes | Yes | No | Free tier only | 3 folders | ~$9/mo |
| ChatGPT Folders (Wimeki) | Yes | Yes | No | Yes | 4 folders | Pro for more |
| NorthLab Folders | Yes | Yes | Yes | Yes | 3 folders | $4.99/mo · $39/yr · $79 lifetime |
| Superpower ChatGPT | Yes | No | No | Mostly | Uncapped folders | ~$15–19/mo |
Easy Folders is one of the more established options and supports both platforms cleanly. The catch is the privacy model on its paid tier: to enable cross-device sync, it transmits your folder names, conversation titles, and conversation URLs to its servers. The developers state they don’t read conversation contents, but chat titles alone can reveal what you’re working on. The free tier stays local but caps you at 3 folders. We’ve written a fuller comparison in our Easy Folders alternative guide.
ChatGPT Folders by Wimeki advertises Claude support alongside ChatGPT and stores data locally. It’s a basic but functional option, with a free tier capped at 4 folders and a roughly 3.9-star average rating from its reported 10,000 users.
Superpower ChatGPT deserves a mention precisely because so many people assume it covers Claude — it doesn’t. It’s a feature-rich overhaul of the ChatGPT interface with a large user base, but it is ChatGPT-only, and its published privacy policy discloses collection of names, email addresses, and IP addresses.
What “works with both” should actually mean
Plenty of extensions technically load on two websites. Genuine cross-platform support is a higher bar. Before installing anything, check for four things.
First, native integration on both sites. The extension should dock into each platform’s own sidebar rather than floating a foreign panel over the page. If it looks bolted-on in Claude but polished in ChatGPT, Claude support was an afterthought — and it’ll be the first thing to break when Anthropic ships a UI change.
Second, permissions scoped to exactly two domains. A ChatGPT-and-Claude organizer needs host access to chatgpt.com and claude.ai, and nothing more. Any request to read data on all websites is unjustifiable for a folder tool. This one check filters out the data-hungry all-in-one sidebars we cautioned about in our extensions roundup.
Third, search that spans both platforms. This is the feature that makes a single extension worth it. If you still have to remember which AI a conversation happened in, the tool has unified your folders but not your history.
Fourth, a consistent export path. Whatever you can export from ChatGPT you should be able to export from Claude, in the same format. Our guide to exporting ChatGPT and Claude chats to Markdown covers why Markdown is the format worth standardizing on.
How NorthLab Folders handles both platforms
We built NorthLab Folders around one design rule: both platforms are first-class citizens. One install adds a folder sidebar inside the native UI of both chatgpt.com and claude.ai — folders, depth-1 subfolders on Pro, pinned chats, date stamps, and one-click Markdown copy work identically on both sites. Cross-chat search spans your conversations on both platforms from a single search box.
The privacy architecture is strictly local-first. Your conversation content never leaves your browser: local storage holds only folder names and the conversation IDs that map chats to folders, never message text. We run no servers that touch your prompts. The only network call the extension makes is a license-key check with our payment processor when you activate Pro.
It’s also, as of mid-2026, the only tool in this market that runs on Safari — via a signed, notarized macOS app — alongside Chrome, Edge, Brave, Arc, and Opera. If you’re on a Mac, we’ve written up the details in ChatGPT folders on Safari.
The honest limitations: we’re a newer entrant without the install base of older competitors, and because we enforce local-first storage, your folder layout lives only on the device where you set it up — there’s no cloud sync of it, by design. If cross-device sync matters more to you than keeping metadata off third-party servers, Easy Folders’ paid tier is the trade-off to consider.
What about Gemini and other AI platforms?
NorthLab Folders supports ChatGPT and Claude today — not Gemini, Grok, or other assistants. Some competitors advertise broader coverage, and if you live in three or more AI tools, that breadth might genuinely serve you better.
But it’s worth being skeptical of very wide platform lists. Every additional supported site is another host permission the extension holds and another UI the developer has to track. In our experience maintaining just two integrations, AI vendors ship interface changes constantly; an extension claiming to support five platforms is making a big maintenance promise. Check the reviews for “broke after the update” complaints before trusting a long compatibility list.

Frequently asked questions
Is there one extension that works for both ChatGPT and Claude?
Yes. A small number of folder extensions genuinely support both chatgpt.com and claude.ai — Easy Folders, ChatGPT Folders by Wimeki, and our own NorthLab Folders, which docks into the native sidebar of both sites from a single install. Most popular organizers, including Superpower ChatGPT, remain ChatGPT-only.
Is it safe to give one extension access to both chatgpt.com and claude.ai?
It can be, if the permissions are scoped correctly. A cross-platform organizer should request host access to chatgpt.com and claude.ai only — nothing else. If an extension asks to “read and change all your data on all websites”, that’s a red flag. Local-first tools add a second layer of safety: your conversation content never leaves the browser.
Do I have to set up my folders twice, once per platform?
With NorthLab Folders you install once and the folder sidebar appears on both chatgpt.com and claude.ai automatically. Each site gets its own folder sidebar in its own native UI, and cross-chat search spans your conversations on both platforms, so finding an old chat doesn’t require remembering which AI you asked.
Does any ChatGPT-and-Claude extension work on Safari?
As of mid-2026, NorthLab Folders is the only ChatGPT and Claude folder extension that ships a signed, notarized Safari app for macOS. Every other tool in this market is Chromium- or Firefox-only, so Mac users who prefer Safari are otherwise locked out.
The bottom line
If you use both ChatGPT and Claude, you don’t need two organizational systems — but you do need to pick a tool where both platforms are genuinely first-class. Check that it integrates natively on both sites, requests permissions for only those two domains, searches across both histories, and exports from both consistently.
We built NorthLab Folders to be exactly that tool, and the free tier — 3 folders, pins, Markdown copy, single-chat export, on both platforms — is enough to judge for yourself whether one extension for everything beats juggling two.
