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

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.

The bot held an ongoing conversation with human customer support, checked in with the user at key points, then followed up by email, getting a same-day refund for a service the user forgot to cancel.

A user had Grok Bot read through a rejected email thread, then draft and send a reply, and ultimately got the refund back from Anthropic.

The author open-sources his Grok Bot setup, which manages tasks in a local SQLite database, spins up subordinate bots, and keeps improving their memory and instructions.

A leak says the Grok 4.7 model slug has appeared in Grok Bot with today's date, suggesting a 2.1T-parameter model could launch today.

A user shares a screenshot suggesting Grok 4.7 is already accessible in Grok Bot, indicating an official release is near.

The author plugged Wannalead into an agent to prep LinkedIn prospect lists daily, still approves every first touch, and booked 3 meetings in a week.

According to its App Store listing, Muse looks more like a proactive assistant that tracks your goals, schedule, and tasks, and it has moved into closed or limited alpha with invite codes now going out.
