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

A SpaceX employee working on Grok Bot says she would never let AI write for her, and the poster uses this to hint at the product's thinking.

After a week of testing Cue, Bot and Muse, the author finds them decent at task execution but far from managing errands and long-term plans as personal life assistants, largely because they lack a world model.

A video walkthrough of the latest Grok Bot updates, the creator's top use cases and setup, and whether it can now run autonomous businesses.

The author calls Muse their favorite personal agent, noting that non-AI-native friends like it too thanks to first-class Meta data access, trust in granting email permissions, and it being free for now.

The author argues the real edge in quant is not generating more strategies but having Grok Bot coordinate a research-backtest-verify-feedback loop with hard rules that reject fake alpha, leaving humans to approve what survives.

Third-party tracking data shows Meta's personal assistant Muse Wonder drew 2.2 times the user spend of the previous-generation Muse Spark 1.3 at the same stage after launch.

Alexandr Wang and Zuckerberg talk for two hours in a pub about Muse's breakout uses, the new Muse Wonder model, agentic commerce and the MSL team.

Meta's CEO acknowledged pledging $100 billion to $200 billion on AI infrastructure without knowing whether it would pay off, and the company has since rolled out the Muse Wonder model and Muse personal assistant.

The author says splitting Grok Bot into six bots burns about 15 times the tokens, and offers six prompts (connectors before browser, stop after three failures, save long results to files) to avoid hitting the weekly limit.

The author built a SCOUT/QUANT/EXEC/RISK layered control so cheap checks run first, avoiding idle overnight runs and irreversible actions.

The developer says their first iOS app was built fully by a Grok Bot plus a Mac mini, has been submitted to App Store review, and declares the app factory is on.

The author mapped Grok Bot to the iPhone Action Button so a press opens voice mode, where they dictate tasks and deadlines for Grok to delegate to bots.
