Unconfirmed: An X account with more than 80,000 followers has circulated claims that a Meta-linked Muse AI Chrome extension is available for testing, which Automatica has not verified.
The X account @testingcatalog said on 13 November 2026 that Muse, which it tagged as a Meta product, has a Chrome extension "already" available for testing.@testingcatalog on X1 The post opens with the label: "META 🔥: Muse is getting a new Chrome extension that can operate on open web pages."
In the same post, @testingcatalog attributed several feature descriptions to what it called a Chrome Web Store listing, quoting text that describes Muse as "Your personal AI agent in Chrome" that can "take everyday tasks off your plate, from filling out forms to comparing prices and following up on refunds," operate in "Chrome’s side panel," and maintain an activity log while requiring users to "Approve actions before they happen" and allowing them to "revoke any connector anytime."@testingcatalog on X1 The quoted description does not identify a publisher, list requested permissions, or name any back-end AI service.
@testingcatalog concluded the post by asserting, "It's already available for testing; check it out below!"@testingcatalog on X1 In the retrieved text, no Chrome Web Store URL, version number or publisher name appears, and the referenced listing itself is not included in the material reviewed.
The retrieved material consists only of this single post; it contains no separate listing URL, documentation or publisher statement beyond what @testingcatalog quotes. Automatica has not independently checked the Chrome Web Store and has not seen any statement from Meta about a Muse Chrome extension.
Evidence that would confirm or disprove the circulating claim would include a verifiable Chrome Web Store listing matching the quoted description, official documentation from the identified publisher, removal or renaming records that can be tied to that listing, or a statement from Meta about Muse and any associated Chrome extension. None of this is present in the material reviewed, so this article reports only what @testingcatalog posted and does not assert that the described extension exists, functions as claimed, or is safe to install.
