Meta now says its personal agent Muse owes most of its design to OpenClaw, the open source project built by Peter Steinberger. Nat Friedman, head of product at Meta Superintelligence Labs, calls it an inspiration he fully owns after using the tool in January. The app passed 500,000 users in seven days.
Key Takeaways
- Muse crossed 500,000 users and 250,000 daily actives in the week following its September 8 launch.
- Nat Friedman confirms the product carries over OpenClaw’s design, down to system file names and the contents of SOUL.md.
- Meta claims the code was written from scratch and aims at a scale the open source project cannot reach alone.

ChatGPTA Launch Curve Steeper Than ChatGPT’s Mobile Debut
Meta shipped Muse on September 8. Seven days later the personal agent counted more than 500,000 users, over 250,000 of them daily, and more than two million prompts entered. The app climbed to the top spot on the US App Store with more than 31,000 ratings.
The benchmark that matters inside those numbers is ChatGPT’s own mobile debut. On comparable platforms and comparable market availability, Muse is growing faster than the app that opened the consumer market for conversational AI. Meta is drawing on an installed base its rivals still have to win one user at a time.
The traction lands on a product that already shipped with a wide functional perimeter. The agent sends emails, books travel and completes purchases on its owner’s behalf, with a capped free tier and two paid plans at 20 and 100 dollars a month.
Meta is pushing a second variant that runs directly on the user’s own machine. Muse Glimmer executes its tasks locally, which answers the main objection from users who refuse to hand their credentials to a remote service.
The Muse brand now spans several pieces inside Meta, from image generation already wired into Instagram and WhatsApp through to the personal agent.
What Meta Lifted From OpenClaw, File by File
OpenClaw is an open source personal agent created by Peter Steinberger, who previously founded PSPDFKit. The project lives on a public repository the community has been growing for months, built around a simple idea: run the assistant on the user’s own hardware and plug it into the messaging apps they already open every day.
Users opened Muse’s configuration files and found the same system file names OpenClaw uses. SOUL.md, the file that defines the agent’s personality and behavioural rules, carries nearly identical contents across both products. The resemblance spread widely before Meta said anything official.
Nat Friedman answered in public. The head of product at Meta Superintelligence Labs, formerly chief executive of GitHub, wrote that Muse was built from scratch while being heavily inspired by OpenClaw as a product. Asked about the matching file names, he owned it: the team decided Peter Steinberger had got those specific things exactly right.
Friedman recounts using OpenClaw in January, then buying hundreds of Mac minis so his team could work with it daily. He calls Steinberger a genius and describes the original harness as pioneering from day one. The stated goal was to take that approach and make it safe and simple enough to reach billions of people.
The licence decides everything else here. A public repository allows the reuse of the code and the conventions it carries, provided its terms are respected. The objection raised by the community lands less on the legality of the move than on the gap between what a listed company takes from a volunteer project and what it gives back.
One detail sharpens the whole sequence. Peter Steinberger joined OpenAI in early 2026, after his project broke out. Meta is therefore drawing on work whose author now sits on the payroll of its most direct competitor.

Personal Agents Turn Into Contested Ground
For the user, account access remains the central question. An agent that handles email, bookings and payments demands permissions almost nobody granted a third-party service two years ago. Muse adoption mostly measures how fast that reluctance is dissolving.
The market is settling around two opposing models. On one side sits the free or 20 dollar agent chasing volume. On the other sits the premium tier Meta is preparing with Hatch, its 200 dollar monthly agent aimed at long professional tasks.
On the competitive side, the pressure just moved up a notch. OpenAI is reportedly working on its own personal assistant, which would put the company against a product derived from a project whose author it hired. The timing of that response will show whether Meta gained real ground or only a news cycle.
Distribution stays the structural advantage. Meta already places its assistant inside private messages on Threads, and the same logic applies to Muse: the agent never needs to be downloaded if the company pushes it into apps that billions of people open daily.
What happens to OpenClaw now is the open question. An open source project that sees its architecture absorbed by a company this size gains a spectacular technical endorsement and loses its home-field advantage. The coming weeks will tell whether the community accelerates or cedes the ground to industrial agents.
