Marvin is the AI assistant built into NIZU Cloud. If you are comparing built-in business AI assistants, the main alternatives are the AI layers inside large CRM suites. Here is an honest comparison.
| Assistant | Built into | Self-hosted / private model option | Real data stays off third-party APIs | Per-workspace own database | Typical cost posture | Overall fit for NIZU users |
|---|---|---|---|---|---|---|
| Marvin (NIZU) | NIZU Cloud WorkSpace | Yes — self-hosted by default | Yes — enforced by design | Yes — each workspace isolated | Included with NIZU | 9 / 10 |
| Salesforce Einstein / Agentforce | Salesforce | Limited / enterprise | Depends on configuration | No (shared multi-tenant) | High (add-ons + premium licences) | 7 / 10 |
| HubSpot Breeze | HubSpot | No | No (cloud LLM) | No | Included in core plans; usage fees | 7 / 10 |
| Zoho Zia | Zoho CRM | Partial | No (cloud LLM) | No | Low to moderate | 7 / 10 |
| Freshsales Freddy AI | Freshworks | No | No (cloud LLM) | No | Moderate | 6 / 10 |
The big CRM suites offer broad, mature “agentic” automation across very large product ecosystems. If you already run your whole business inside Salesforce, HubSpot or Zoho, their native assistant will be deeply integrated with that suite. Marvin's advantage is for teams that run on NIZU and want a private, data-isolated assistant without adopting another platform.
