Meta AI Muse Spark upgrade moves assistant into workplace tasks

Meta AI Muse Spark is moving the company’s assistant closer to everyday office work, with new features that can connect to email and calendars, conduct web research, generate presentation slides and complete multi-step tasks, Meta said in a July 24 announcement. The upgrade, powered by a new model called Muse Spark 1.1, comes as Meta has spent more than $100 billion on AI infrastructure and faces investor scrutiny over when that outlay will produce returns.

Meta said the assistant is beginning to “take action on your behalf,” describing a move from answering prompts toward following through on tasks over time. The features are being introduced in select markets through the Meta AI app and meta.ai, with WhatsApp integration expected in the coming weeks, according to the company.

The shift extends Meta’s AI push beyond advertising tools, WhatsApp business features and Ray-Ban smart glasses. It also follows a restructuring of the company’s research operation around what Chief Executive Mark Zuckerberg has called “personal superintelligence.”

What can Meta AI Muse Spark do?

Muse Spark 1.1 is the model behind Meta AI’s latest task-oriented functions, according to Meta. The assistant can use connected email and calendar access, produce slide decks, perform web research and handle recurring or multi-step requests with less repeated prompting.

Those functions overlap with the core uses of workplace AI products. Microsoft has positioned Copilot around productivity software, while Google has built Gemini into Workspace. Meta’s route is different because its assistant already reaches consumers through Facebook, Instagram, WhatsApp and Messenger.

Absolute Geeks reported that Meta also presented consumer examples, including a mood board built from Facebook Marketplace listings for a kitchen renovation and a week-by-week half-marathon training plan. The email, calendar and presentation features, however, place the assistant nearer to the software employees use during the workday.

Distribution gives Meta a scale advantage, but workplace adoption depends on trust as well as reach. A consumer may try an assistant inside a social app without granting it access to a work inbox or calendar.

How does Meta compare with workplace AI rivals?

Recon Analytics data on the U.S. enterprise AI market found that ChatGPT converts 83.1% of paid subscribers who have workplace access to their preferred AI platform. Microsoft Copilot converts 35.8%, according to the same data.

Recon Analytics also found that Copilot’s share among paid AI subscribers declined from 18.8% in July 2025 to 11.5% in January, a 39% contraction, despite its integration with Windows and Microsoft 365. The figures show that bundling does not by itself guarantee regular use by employees.

Meta is scheduled to report second-quarter results on July 29. In its first-quarter report, the company raised its full-year capital expenditure guidance to $125 billion to $145 billion, from a previous range of $115 billion to $135 billion, citing higher memory costs and more data centre capacity, PYMNTS reported.

PYMNTS also reported that Meta said it had consistently underestimated its own computing needs. The Muse Spark upgrade gives the company a broader product story to discuss with investors: AI spending that supports user-facing assistant functions, not only improvements to advertising systems or internal efficiency.
