By September 18, CEO Mark Zuckerberg was already handing the keys to outside developers.\n\nThe move opens a new developer submission portal at muse.ai/platform, where third parties can build and submit custom connectors for review. New connectors went live the same day Zuckerberg made the announcement.\n\n## What Muse actually does\n\nThink of Muse as a personal assistant that sits on top of your digital life. It connects to apps like Gmail, [Google](https://cryptobriefing.com/markets/alphabet/) Calendar, and Spotify, then acts on your behalf across them.\n\nThe key design choice is individual authorization: users approve each connection separately, rather than granting blanket access to everything at once.\n\nMuse runs on iOS, Android, and the web through muse.ai, with WhatsApp support already in place and AI glasses on the roadmap. Meta is pricing the service in tiers, with a Power plan at $20 per month and a Maximum plan at $100 per month, each offering progressively higher usage limits.\n\n### AI, tech, and the markets they move—in one daily briefing.\n\nDaily. Free. Join 34,000+ readers across crypto, finance, and policy.\n\n## Why opening the connector ecosystem matters\n\nDevelopers submitting connectors must meet Meta’s functional, security, and legal requirements before anything goes live.\n\nWhat remains undisclosed is everything developers actually need to plan around: agreement terms, fees, revenue sharing arrangements, and how long the review process takes.\n\n## The competitive picture\n\nThe research indicates that Stripe is involved as a payment facilitation layer, which points toward a future where Muse connectors could enable transactional capabilities, not just read-and-summarize functions.\n\n**Disclosure:** This article was edited by Editorial Team.
