Best Microsoft Edge Extensions for ChatGPT and Copilot

TL;DR: Microsoft Edge has no built-in ChatGPT the way it has built-in Copilot, so if you want ChatGPT features inside the browser you need an extension, and several genuine ones exist on the Edge Add-ons store. We verified AIPRM for ChatGPT, WebChatGPT, and others directly, checked Edge's own Manifest V2 phase-out timeline against Chrome's, and covered installing a Chrome extension in Edge for anything that isn't listed natively, including our own extension.

Is Microsoft Copilot the same thing as ChatGPT?

No, and this is worth settling before anything else in this post, because the keyword that brought a lot of readers here, "copilot extension edge," usually means one of two very different things.

Microsoft Copilot is Microsoft's own AI assistant, built directly into Edge. It lives behind the sidebar icon, ships with the browser, and needs no install, no account setup beyond signing into Windows or Edge, and no trip to any add-ons store. If your Copilot icon has gone missing, that's a settings or managed-device policy problem, not a missing extension, and searching the Edge Add-ons store for "Copilot" won't fix it, because Copilot was never something you install from there in the first place.

ChatGPT is OpenAI's product, and Edge has no native version of it. You reach ChatGPT either by going to chatgpt.com directly or by installing a third-party extension that adds shortcuts, prompt storage, or other conveniences around it. Nothing about ChatGPT ships with Edge itself.

GitHub Copilot is a third product again, mostly living in code editors like VS Code and JetBrains IDEs and on github.com, not as a general-purpose Edge browsing extension. If a search result promises "GitHub Copilot for Edge," check carefully whether it's actually GitHub's product or a third party that has simply put "Copilot" in an unrelated extension's name, which happens more often on Edge's store than you'd expect (more on that below).

The confusion is easy to fall into because Microsoft itself uses "Copilot" as a brand name across several genuinely different products: the assistant built into Edge, a Microsoft 365 add-in inside Word and Excel, and a security-focused Copilot for IT admins, on top of GitHub's separately-owned Copilot for code. None of them share a codebase, and none of them are the same thing as ChatGPT, even though all of them are large language model chat assistants doing broadly similar work. When a search result promises a "Copilot extension for Edge," it's worth asking which Copilot, and whether it's actually a Microsoft product at all rather than a third party that borrowed a popular word for its own listing title (see the naming-collision section further down for two real examples of exactly that).

So: Copilot needs no extension. ChatGPT needs either a browser tab or a genuine extension. GitHub Copilot mostly needs neither, since it belongs to your editor. Keeping those three straight before you search the Edge Add-ons store saves you from installing the wrong thing entirely.

Is Manifest V2 being phased out of Edge the way it was in Chrome?

Only on a slower timeline, and conflating the two is an easy mistake to make right now. Chrome's own developer documentation marks 31 August 2026 as the date when, in its own words, "All remaining Manifest V2 extensions are removed from the Chrome Web Store." Anything already installed on an older Chrome build stops receiving updates from that point on. That happened three days before this was written.

Microsoft Edge's own documentation and its extensions team describe a different pace. Microsoft's developer docs list August 2026 as the point where a Manifest V2 deprecation warning starts appearing in Partner Center, with enterprise deprecation "expected to begin" in early 2027, and no fixed date yet for when Partner Center stops accepting updates to Manifest V2 extensions at all. The Microsoft Edge Blog is more specific about the consumer side: starting in August 2026, a subset of users with Manifest V2 extensions installed began seeing notices on the Manage Extensions page and on Edge Add-ons product pages, with Manifest V2 extensions being "gradually turned off by default" over the following months, rolling from the Canary, Dev, and Beta channels out to Stable, with the stated goal of "completing the consumer transition by the end of 2026."

The same post puts a number on how much of the ecosystem has already moved. In its own words: "there are only 58 MV2-based extensions in the Edge Add-ons website with any meaningful usage. Of these, only three don’t have a publicly available MV3-based extension already available." So the practical takeaway for a reader choosing an extension today is not "Edge just did what Chrome did." It's that Edge is mid-rollout rather than finished, an extension that vanished from Chrome on 31 August hasn't necessarily vanished from Edge on the same date, and every extension in the table below is Manifest V3, so this phase-out doesn't affect any of them either way.

Which extensions for ChatGPT did we actually verify on the Edge Add-ons store?

Every row below comes from that extension's own listing on the Edge Add-ons store, checked directly on 3 September 2026. We did not install and test each one end to end; where a listing states a capability, that's what's reported here, and we're not stating star ratings, review counts, or install numbers, since those change constantly and several already-published numbers on other sites are wrong the day someone reads them.

AIPRM for ChatGPT adds a library of curated prompt templates on top of ChatGPT, organized by category (SEO, sales, support, and more), plus custom lists and writing-tone presets on its paid tier. It's the most actively maintained of the group here and was already a well-known name on Chrome before it reached Edge.

WebChatGPT takes a different angle: instead of managing prompts, its own listing describes it as adding "relevant web results to your prompts to ChatGPT for more accurate and up-to-date conversations." That's essentially live search grounding bolted onto ChatGPT, plus a smaller built-in prompt library on the side.

Anything Copilot is the one worth reading carefully rather than assuming from the name. Its own listing describes it as a "universal shell" for the Edge sidebar: it doesn't provide an AI model of its own, but lets you open ChatGPT, Gemini, Microsoft Copilot, or several other AI sites inside a sidebar or popup, with no login or account required for the basic version. Useful if what you actually want is a place to keep several AI chat sites open side by side, less useful if you specifically wanted a prompt manager.

AI Workspace Pro and Promptory are both far smaller by any measure we can state (we're not citing install counts, but the gap between these two and AIPRM or WebChatGPT is large). AI Workspace Pro bills itself as a ChatGPT prompt manager and sidebar workspace for organizing prompts, chats, and notes. Promptory's pitch is narrower and, notably, cross-platform: its listing says it auto-saves every message you send to "ChatGPT, Claude, Gemini, Perplexity, Grok, or Copilot" in the background, which makes it one of the few extensions here that explicitly names Copilot (almost certainly Microsoft's copilot.microsoft.com, based on the company it's listed alongside) as a platform it captures from, rather than just borrowing the word for its own title.

What permissions should you check before installing one of these?

Every one of the extensions above needs to read and modify the ChatGPT page to do its job, which means it's asking for real permissions, not a formality. Taking AIPRM's own published manifest as a concrete example (the same manifest data that produced the version and Manifest V3 status in the table above): it requests activeTab, contextMenus, scripting, and storage, plus declarativeNetRequestWithHostAccess and webRequest, scoped specifically to chat.openai.com. That combination is roughly what you'd expect from a tool that injects buttons into the ChatGPT page, saves data locally, and reacts to network requests on that one site. It isn't asking for your bookmarks, your browsing history on other sites, or your downloads folder.

The general check that applies to any of these, not just AIPRM: open the extension's permissions before installing (Edge shows this at install time, and again any time from edge://extensions) and ask whether the list matches what the extension claims to do. A prompt manager asking for access to ChatGPT and nothing else is normal. The same extension asking for access to every site you visit, or for permissions like reading clipboard content unrelated to its stated feature set, is worth a second look before you click Allow.

Can you install a Chrome extension in Microsoft Edge instead?

Yes, and Microsoft documents this directly rather than leaving it as a workaround. Microsoft's own support page states plainly: "Extensions designed for Google Chrome can also be used in Microsoft Edge." The steps, per that same page: open the Chrome Web Store from inside Edge, find the extension, open its product page, and select Get extension. If you haven't already approved it, Edge shows a prompt to "Allow extensions from other stores" — select Allow, review the requested permissions, and select Add extension to finish.

That single sentence in Microsoft's own documentation is also the honest caveat: Chrome extensions aren't necessarily tested against Edge, because the two browsers run separate review processes even though they share the same Chromium engine underneath. In practice this rarely breaks anything for a typical ChatGPT-focused extension, but it's why an extension with a dedicated, actively maintained Edge listing (like the ones in the table above) is generally the safer default over sideloading a Chrome one, when both options exist for the same job.

This is also the path for comparing prompt manager extensions more broadly: most of the tools reviewed for Chrome across that kind of roundup are installable in Edge the same way, even without a separate Edge-native listing.

Is Prompt Architects available for Microsoft Edge?

Not as a dedicated Edge Add-ons listing, as far as we could find after checking directly on 3 September 2026. Prompt Architects is published on the Chrome Web Store and on Firefox Add-ons, and the Chrome Web Store version installs into Edge through the same "Allow extensions from other stores" flow covered above. If you're on Edge and want to use it, that's the path today: open the Chrome Web Store listing from inside Edge and install it from there rather than searching Edge's own store for it.

Which one should you actually pick?

If prompt templates and a curated library are what you're after, AIPRM is the most established name here and the one most likely to already have what you're looking for. If you want ChatGPT answers grounded in live web results rather than prompt storage, WebChatGPT is built specifically for that. If your real complaint is juggling too many AI chat tabs, Anything Copilot's sidebar is solving a different problem than either of those, worth knowing before you install it expecting a prompt manager.

And if what you actually want is one tool that also works the same way on Chrome and syncs your prompts, variables, and library across more than just ChatGPT (Claude and Gemini included), that's the gap none of the Edge-native options above are built to close, and it's why we build Prompt Architects the way we do.
