Private AI: deployment and team size
A dedicated database, customer-managed encryption keys and a server on your own infrastructure describe different controls. Compare application hosting, model endpoints and the minimum size for that exact setup. Deployment details checked on 14 October 2026; sources and qualifications are linked in each comparison. On smaller screens, scroll the table horizontally.
| Provider | Application on your infrastructure | Local models and data flows | Minimum size for the deployment |
|---|---|---|---|
| chifty | Application and knowledge base on your own infrastructure; agree the setup and operating responsibilities individually. | Supported local models by agreement. Fully local processing requires local model endpoints and appropriately configured integrations. | Individually planned for small and midsized companies too. Agree users, hardware, models and implementation in the quote. |
| Langdock | EU cloud as standard; Langdock-managed dedicated hosting, your own cloud and on-premise are Enterprise options. | Check application hosting separately from model processing. Own-cloud or on-premise hosting alone does not establish exclusively local model endpoints. | Langdock-managed single tenant from 2,000 seats; own cloud and on-premise from 5,000 seats according to the security page. |
| amber | Business includes a dedicated environment and database. Clarify customer-owned infrastructure terms in the Enterprise quote. | Multiple AI models; Enterprise lists own LLM keys. Confirm in the quote whether the models can also run entirely on customer-owned infrastructure. | Business from 50 licences; Enterprise from 200 users for individual infrastructure and compliance requirements. This does not establish fully local deployment. |
| Microsoft 365 Copilot | Microsoft 365 Copilot is a cloud offering. The reviewed vendor documentation does not describe a self-hosted application server. | Processing within the documented Microsoft cloud architecture. No documented option using entirely customer-operated AI models. | No documented minimum size for self-hosting because that deployment is not documented. Check cloud licensing requirements separately. |
| Superhuman Mail | Superhuman Mail is hosted on Google Cloud Platform according to its Data Privacy Addendum. No documented on-premise option. | Cloud and AI processing according to vendor documentation. Customer-managed encryption keys for the AI memory layer do not mean customer-operated applications or models. | No documented minimum size for self-hosting because no such option is described. Check Mail plans and Enterprise terms separately. |

There is no single best AI product for every company. Use the same scope and sample tasks to make differences visible. These guides are published by chifty and link to dated vendor information.
Discuss your requirementsDefine the result
An approved email, a sourced answer or work directly in an Office application: select a measurable outcome.
Check the source and access
Name the required systems and roles. Include restricted, outdated and missing information in the evaluation.
Identify the deployment
Distinguish dedicated vendor hosting, your cloud and on-premise. Check model endpoints and minimum seats for the exact option, then include hardware and operations in the quote.
Compare the complete cost
Include seats, mailboxes, base licences, usage, implementation and internal review effort over the same period.
