AI Personal Assistants: Muse, Grok Bot, Cue Usage & Comparisons

Meta released Muse, a personal AI agent that can shop online, manage emails and complete tasks with user approval.

Meta's press release describes Muse as an agent that does work across the apps you already use and turns long-term goals into action plans, not just answering questions.

A user reviewing Meta's new personal agent Muse points out that it already has payments and Stripe Link built in, so it can complete order-type actions directly.

Meta's official account posted a video introducing Muse, a personal AI agent it says gets things done across every part of life, with a link to download the app.

When Grok Bot reaches a site that needs an account, it pauses so you can authenticate yourself through a password manager like 1Password or Apple Passwords, then continues the task.

The author used Grok Bot to pull from their calendar and email and print a morning newspaper while they sleep, instead of checking their phone first thing.

A user had their bot order IKEA furniture and book a Taskrabbit for delivery and assembly, and shared a photo of the finished shelves.

Six curated Grok Bot communities on X cover GTM, marketing, recruiting, engineering, product and design, with limited spots requiring an application form.

After the author sent a first cold email via ListKit, a Grok Bot took over the reply, handled the recipient's objection and booked a Thursday 2PM call directly.

On Lenny's podcast, Grok Bot product lead Roman Ugarte explains why it was built fresh instead of inside Cursor, two key bets, manual onboarding of the first users and cutting features before launch.

The author connected Meta Muse Code to a project that manages and coordinates other agent harnesses inside Codex, and says Muse Spark 1.3 Contributor is cheaper than DeepSeek V4 Flash was before its price increase.

A user claims Meta's Muse Spark promotion cropped the faster Gemini 3.8 Flash out of a comparison, questioning its performance claims.
