Always-on agents, or an organisation that learns.
Grok Bot and Mellovy both give AI colleagues a computer and let them work on their own. The difference is who writes the memory, who checks the work and whether each colleague gets its own computer.
What is Grok Bot?
SpaceXAI calls it "your team of always-on agents." Each Bot has a name and a job, works in the cloud around the clock and learns a routine when you show it a task once. Bots message each other and can share a group chat.
It’s good at a lot. It runs on desktop and iOS, it learns routines by demonstration, and an independent review model checks risky actions before they run. It’s in beta, and it comes with SuperGrok and Cursor plans.
What is Mellovy?
Mellovy is an AI-native company. People and AI colleagues work in one organisation that shares memory, a mission and standards, and it gets better as it grows.
Mellovy takes Grok Bot’s idea to the extreme and organises it the way people work. Something other than the colleague who did the work judges every result, and the evaluation writes the memory.
Where do they differ?
We took each Grok Bot line below from its own docs on September 28, 2026. If something here is out of date, tell us and we’ll fix it.
- Memory
- A Grok Bot keeps facts and summaries from its own work, and its review layer skips memory writes. In Mellovy the evaluation writes the memory, at the organisation, department and individual level.
- Computer
- All Grok Bots share one cloud computer, and the docs say separate Bots aren’t a security boundary. Each Mellovy colleague gets a whole computer of its own.
- Review
- Grok Bot’s Auto Review checks risky actions before they run. Mellovy reviews every tool call, with a reviewer that can’t see the colleague’s reasoning.
- Quality
- Grok Bot’s docs describe approval of actions. Mellovy also judges the result of every piece of work and keeps each correction as a test case.
- Access
- Grok Bot is open to SuperGrok and Cursor subscribers. Mellovy is invite only, with seven days of limited usage once you’re in.
When is Grok Bot the better pick?
If you already pay for SuperGrok or Cursor and want a few personal agents today, on your phone too, Grok Bot is there now. Mellovy is invite only for now.
Pick Mellovy when you want the whole organisation to get better as it grows, and you don’t want to be the one who keeps its agents from drifting.
Questions about Mellovy and Grok Bot.
- What’s the main difference between Mellovy and Grok Bot?
- Who keeps the work from drifting. A Grok Bot writes its own memory and shares one computer with the other Grok Bots. In Mellovy the evaluation writes the memory, every colleague has its own computer and something other than the colleague judges every result.
- Does Mellovy have routines like Grok Bot?
- Yes. Show an AI colleague a task once on its computer and it becomes a routine. Mellovy also judges each run of it.
- Is Grok Bot’s chief of staff the same as a Mellovy manager?
- You set up both yourself. SpaceXAI describes a chief of staff as how its own people use Grok Bot. In Mellovy, structure grows out of the work, and your organisation decides whether it has managers at all.
