Comparison
All three are available to you today. Most teams should start in the middle column — the right-hand column is the advanced build, and it assumes the middle one is already in place.

Nexus — AI Employees Advanced build |
|
|---|---|---|---|
| What it is | One person, one assistant | A super assistant for the whole team, fully wired and deployed | A fleet of AI employees with real roles |
| Identity | Runs as the person using it | Runs as the person using it | Each employee has its own accounts and seats — own email, Slack handle, and CRM login |
| Connections | Whatever ships in the box | Off the shelf, plus custom connectors for your internal and no-API tools, shared across the team | All of that, pre-authorized and grouped per role, so each one carries only what it needs |
| Skills | Each person builds their own, from scratch | Shared library — managers decide the best practices everyone runs | Shared library, grouped by role, so each employee is focused and easy to hand off |
| Rules | Each person sets their own, if they bother | Set once by managers, enforced for everyone | Set per role — the finance employee's limits aren't the sales employee's |
| Data lookups | Re-fetched every time — slow and expensive | Cached in a central searchable store | Cached centrally, scoped per role |
| Where you use it | The vendor's chat window or CLI | The vendor's chat window or CLI | Slack, email, your project management tool, or an app of your own |
| Managing the work | A list of recent chats | A list of recent chats | Your project management tool, so work has a state and an owner |
| Recurring work | The vendor's cloud scheduler, with its limits | The vendor's cloud scheduler, with its limits | Recurring tasks, webhooks, and a central scheduler |
| Model | One model, one vendor | One model, one vendor | Model- and harness-agnostic, including self-hosted |
| Cost | Subscription, plus overages, plus cloud costs | Subscription, plus overages, plus cloud costs | Auto model routing and leaner context, on subscriptions you already pay for |
| Internal apps | Throwaway apps that run on one laptop | Throwaway apps that run on one laptop | Built, hosted, and permissioned for the whole team |
Off-the-shelf integrations and cloud schedulers both have real limits — they aren't equivalent to running against your own systems. That gap is most of what the middle column is for.
