AI agents for business compared: EWE versus ChatGPT, Claude, Gemini, Copilot, Mistral, DeepSeek, Muse and Grok

A chatbot answers. An agent works.

A conversational assistant waits for your question and answers it, in its window, with its vendor’s model. EWE starts from a goal: it plans, acts on your tools, checks the result, reports back — and remembers it for next time.

It acts, it doesn’t just answer

Web, files, documents, messaging apps, business software: EWE carries out the steps itself, in an isolated space, and asks for your approval before any sensitive action. You get a result, not a list of tips to apply.

It remembers, and that memory belongs to you

Decisions, preferences, the context of each project: EWE records them in readable files, on your server. They can be reread, corrected and backed up. Nothing disappears with a cancelled subscription or a change of model.

It learns from every task

When a difficult task succeeds, EWE writes down the method that worked and reuses it next time, improving it if the context changes. The second time, it no longer searches: it applies. The agent becomes an asset that gains value, not a recurring expense.

The right model for each task

A frontier model for reasoning, a fast and economical model for sorting or rewording, a local model for sensitive data: EWE combines them, and switches to another provider if one goes down. When a better model comes out, you adopt it the same day, without rebuilding anything.

Where your teams work, even at night

EWE runs continuously on your server. You mention it in Slack, Teams or WhatsApp like a colleague; it keeps its routines — Monday report, monitoring, watch — even when every computer is switched off.

On your premises, under your control

Installed on your infrastructure, EWE keeps memory, files and history with you; with a local model, nothing leaves. For regulated industries (healthcare, finance, legal, public sector), this is often the condition for moving from pilot to production.

EWE does not oppose the big vendors’ models: it uses them, along with the others. What it refuses is being locked into just one.

In technical terms: EWE is an AI orchestrator: an autonomous artificial intelligence, also known as agentic AI. It combines model-agnostic LLM routing across more than 300 models, the Model Context Protocol (MCP) to plug into any software, a closed learning loop (every successful task becomes a reusable skill) and the automation of complex workflows, on sovereign infrastructure: on-premise, a European virtual machine or a private cloud.

EWE plugs into more than 45 everyday applications, and into any MCP-compatible tool

Example · one customer email, four applications, zero copy-paste

1. Outlook: A customer writes: their order is late.
2. HubSpot: EWE finds their account and the history of their exchanges.
3. SAP: It checks the stock and the new shipping date.
4. Microsoft Teams: It alerts the account manager and drafts the reply.
5. You: You approve in one click. It sends, and remembers.

Illustration: the software varies from one company to another, the mechanics stay the same.

EWE versus eight assistants on the market, on ten sourced criteria

Every model on the market, local ones included

No model is the best at everything, or forever. Being able to take the best from each vendor, task by task, and switch when a new model comes out means never falling a generation behind.

• EWE (● yes): The AIs from OpenAI, Anthropic, Google, Mistral, DeepSeek, Qwen, Llama and many more, or your own AI installed on your servers. You switch model with one command; if a provider goes down, EWE moves to another one on its own.
• ChatGPT (○ no or not documented): ChatGPT only offers OpenAI models, whose catalogue the vendor alone decides. (sources: 1)
• Claude (○ no or not documented): The Claude apps and Claude Cowork run on Anthropic models only. (sources: 16)
• Gemini (○ no or not documented): The Gemini app only offers Google models; Claude is only available on Google Cloud’s developer platform. (sources: 28)
• Microsoft 365 Copilot (◐ partial): Two vendors, chosen by Microsoft. Anthropic models are disabled by default in the EU, EFTA and the United Kingdom. (sources: 18)
• Mistral Vibe (formerly Le Chat) (○ no or not documented): Vibe runs on Mistral models, some of which are open (and usable in EWE). (sources: 38, 39)
• DeepSeek (○ no or not documented): The app offers DeepSeek models. These models are open: EWE can run them on your premises. (sources: 48, 49)
• Meta Muse (○ no or not documented): The Muse agent is built on Meta’s Muse Spark model. (sources: 23)
• Grok (○ no or not documented): Grok Business and Enterprise give access to xAI models. (sources: 24)

Installed on your premises, even offline

An agent that reads your contracts and acts on your tools is part of your information system. Installing it yourself means deciding on its security, its updates and its availability, without depending on a third-party service.

• EWE (● yes): On your server, a rented server, your private cloud or even an air-gapped machine. With an AI installed on your premises, it works without the internet. Its actions run in isolated spaces, and the most sensitive ones wait for your green light.
• ChatGPT (○ no or not documented): Service hosted by OpenAI; no installation on your infrastructure. (sources: 3)
• Claude (○ no or not documented): Service hosted by Anthropic. On the developer side, actions can run on your premises, but the model stays with Anthropic. (sources: 11)
• Gemini (◐ partial): Gemini models available on Google Distributed Cloud, including air-gapped; no installable app for the general public. (sources: 29)
• Microsoft 365 Copilot (○ no or not documented): Microsoft 365 service hosted by Microsoft. (sources: 18)
• Mistral Vibe (formerly Le Chat) (● yes): The Enterprise plan can be deployed on-premise, in a private cloud or on Mistral’s cloud. (sources: 40, 41)
• DeepSeek (○ no or not documented): The app cannot be installed; only the models, published openly, can be installed separately. (sources: 49)
• Meta Muse (○ no or not documented): Consumer agent hosted by Meta. (sources: 23)
• Grok (○ no or not documented): Hosted service; the Enterprise “Vault” plan isolates data in a dedicated space with customer-managed keys, still at xAI. (sources: 24)

Your data in Europe, or on your premises

GDPR, trade secrets, the AI Act: knowing exactly where data resides (and who can access it) determines whether an agent can be used in sensitive industries.

• EWE (● yes): Memory, files and history stay on your infrastructure. Only the requests sent to the chosen model leave it; with a local model, nothing leaves.
• ChatGPT (◐ partial): Data storage in Europe offered on the Enterprise and Edu plans; request processing in Europe for some eligible Business customers. (sources: 3)
• Claude (○ no or not documented): On Anthropic’s platform, data is stored in the United States; EU hosting is only possible through a partner cloud, via the developer offering. (sources: 11)
• Gemini (◐ partial): Data storage in the EU for Gemini Enterprise Standard and Plus; nothing documented for the consumer app. (sources: 30)
• Microsoft 365 Copilot (◐ partial): Microsoft 365 applies its EU Data Boundary, but Anthropic models are excluded from it. (sources: 18)
• Mistral Vibe (formerly Le Chat) (● yes): Data hosted in the European Union by default, with possible temporary transfers depending on sub-processors. (sources: 42)
• DeepSeek (○ no or not documented): According to its privacy policy, DeepSeek collects, processes and stores personal data in the People’s Republic of China. (sources: 47)
• Meta Muse (○ no or not documented): Launched in the United States; no European availability or residency announced to date. (sources: 23)
• Grok (○ no or not documented): No European data residency publicly documented to date. (sources: 24)

A memory that belongs to you

An agent’s memory becomes an asset: decisions, preferences, business context. If it lives with the vendor, it leaves with the subscription. As files on your premises, it can be read, corrected, backed up, and it survives any change of model.

• EWE (● yes): Plain text files on your server, plus an index that finds any past conversation: you read them, correct them and back them up like any document.
• ChatGPT (◐ partial): Memory viewable and deletable in the settings; stored by OpenAI. (sources: 4)
• Claude (◐ partial): Memory viewable and editable, importable and exportable as text; stored by Anthropic. (sources: 12)
• Gemini (◐ partial): Memory of past conversations (personal accounts); can be turned off, corrected by deleting exchanges. (sources: 31)
• Microsoft 365 Copilot (◐ partial): Copilot Memory, viewable and deletable; stored by Microsoft. (sources: 19)
• Mistral Vibe (formerly Le Chat) (◐ partial): Knowledge base viewable, editable and exportable; stored by Mistral. (sources: 43)
• DeepSeek (○ no or not documented): No cross-conversation memory documented to date. (sources: 48)
• Meta Muse (◐ partial): Muse remembers information and can “forget” on request; stored at Meta. (sources: 23)
• Grok (◐ partial): Grok Bot remembers preferences and work history; stored at xAI. (sources: 25)

It writes and improves its own methods

An agent that builds on experience gets faster and cheaper with every task: the second time, it no longer searches, it applies. That is the difference between a tool and a colleague who improves.

• EWE (● yes): After a complex task, EWE writes down the procedure that worked, reuses it, and updates it when the context changes. Human approval can be required for every write.
• ChatGPT (◐ partial): Skills available on business plans; created in conversation then installed by the user. (sources: 5)
• Claude (◐ partial): Skills created in conversation, editable and shareable. (sources: 13)
• Gemini (◐ partial): Gemini creates a skill when asked, applies it when useful and edits it in conversation. (sources: 32)
• Microsoft 365 Copilot (◐ partial): Copilot Cowork includes ready-made skills (calendar, briefing…). (sources: 20)
• Mistral Vibe (formerly Le Chat) (◐ partial): On request, Vibe drafts a skill submitted for your review. (sources: 44)
• DeepSeek (○ no or not documented): No reusable-skills feature documented. (sources: 48)
• Meta Muse (○ no or not documented): No reusable-skills feature documented to date. (sources: 23)
• Grok (◐ partial): Skills saved on request; a skill learned by demonstration remains a draft to refine. (sources: 26)

Where your teams already talk

This is where adoption is won: an agent you mention in Slack, Teams or WhatsApp gets used from day one; a new tool you have to open gets forgotten.

• EWE (● yes): Slack, Microsoft Teams, WhatsApp, Telegram, Discord, Signal, email, SMS… One agent, one memory, on every channel.
• ChatGPT (◐ partial): Web, mobile, desktop and a Slack app (not available for Plus and Pro in the European Economic Area). WhatsApp has no longer been offered since 15 January 2026. (sources: 6, 7)
• Claude (◐ partial): Web, desktop, mobile, Chrome extension, Slack (beta, Team and Enterprise plans) and Microsoft 365. (sources: 14)
• Gemini (◐ partial): Web, mobile, Mac, and a Slack app for Gemini Enterprise. (sources: 33)
• Microsoft 365 Copilot (◐ partial): Teams, Outlook and the Microsoft 365 apps. (sources: 20)
• Mistral Vibe (formerly Le Chat) (◐ partial): Web, mobile and developer tools; its agents report back in Slack and Teams. (sources: 38, 39)
• DeepSeek (◐ partial): Web app, iOS and Android. (sources: 48)
• Meta Muse (◐ partial): Muse app, muse.ai and WhatsApp. (sources: 23)
• Grok (◐ partial): grok.com, X, desktop and mobile apps. (sources: 25)

A team of agents, each on the right model

Having a powerful model orchestrate and an economical model handle repetitive tasks cuts the bill without sacrificing quality.

• EWE (● yes): The main agent splits the work between several agents moving forward at the same time; each can use an AI from a different provider.
• ChatGPT (◐ partial): Several agents in parallel in Codex, its developer tool, on OpenAI models. (sources: 9)
• Claude (◐ partial): Claude Cowork coordinates tasks in parallel, on Anthropic models. (sources: 16)
• Gemini (◐ partial): Gemini Spark runs up to 15 tasks in parallel, on Google models; Spark is not offered in the European Economic Area. (sources: 34)
• Microsoft 365 Copilot (◐ partial): Several coordinated agents in Copilot Studio, with a choice limited to the models offered by Microsoft. (sources: 18)
• Mistral Vibe (formerly Le Chat) (◐ partial): Several tasks and agents in parallel, mainly for code, on Mistral models. (sources: 38)
• DeepSeek (○ no or not documented): No agent team documented in the app. (sources: 48)
• Meta Muse (○ no or not documented): A single personal agent; no agent team documented. (sources: 23)
• Grok (◐ partial): Several bots can work in parallel, on xAI models. (sources: 25)

You decide when to change model

When a vendor retires a model, everything built on it has to follow the vendor’s schedule. Keeping control of that schedule protects months of work.

• EWE (● yes): A model disappears at a provider? You switch to another one with one command, memory and skills intact. An open model hosted on your premises cannot be taken away from you.
• ChatGPT (○ no or not documented): On 13 February 2026, OpenAI retired GPT-4o, GPT-4.1, GPT-4.1 mini and o4-mini from ChatGPT; further shutdowns are scheduled in the developer offering. (sources: 1, 2)
• Claude (○ no or not documented): The models available in the Claude apps are set by Anthropic. (sources: 16)
• Gemini (○ no or not documented): Google publishes the shutdown dates of its models. (sources: 35)
• Microsoft 365 Copilot (○ no or not documented): The models offered are set and enabled by Microsoft and the administrator. (sources: 18)
• Mistral Vibe (formerly Le Chat) (○ no or not documented): Mistral publishes the end-of-life and retirement dates of its models. (sources: 45)
• DeepSeek (○ no or not documented): Models were retired from its developer offering in July and September 2026. (sources: 50)
• Meta Muse (○ no or not documented): A single model, set by Meta. (sources: 23)
• Grok (○ no or not documented): The models offered are set by xAI. (sources: 24)

Routines that run without you

Weekly reports, monitoring, watch: a useful agent also works when nobody is asking it anything. Here, several competitors do the job well.

• EWE (● yes): Routines in plain language (“every Monday at 8 am…”), background tasks and reactions to events, run by the EWE service, with no cap imposed by a vendor.
• ChatGPT (● yes): Scheduled tasks run by OpenAI, even when you are offline; 10 active tasks on Business, 15 on Enterprise and Pro. (sources: 8)
• Claude (● yes): Recurring tasks in Claude Cowork, with the computer off; those touching local files stay local. (sources: 15)
• Gemini (● yes): Up to 10 scheduled actions, run by Google in the background. (sources: 36)
• Microsoft 365 Copilot (◐ partial): Up to 10 prompts scheduled in advance. (sources: 21)
• Mistral Vibe (formerly Le Chat) (● yes): One-off or recurring unattended tasks; 5 on Pro, unlimited on Team. (sources: 46, 41)
• DeepSeek (○ no or not documented): No scheduled task documented. (sources: 48)
• Meta Muse (◐ partial): Muse keeps working on its tasks once the app is closed; no scheduling documented. (sources: 23)
• Grok (● yes): Routines run on a computer in the cloud, laptop closed. (sources: 26)

Your in-house software, through a universal plug

MCP is a kind of universal plug: it connects an agent to your management software, your databases or a tool built in-house, without waiting for a vendor to sign a partnership. Created by Anthropic, it has become the industry standard: here, most players are on board.

• EWE (● yes): Any MCP-compatible software plugs in with a few lines of configuration, on top of the built-in tools.
• ChatGPT (● yes): Full MCP support in the developer mode of the Business, Enterprise and Edu plans. (sources: 10)
• Claude (● yes): Anthropic created MCP in 2024, then handed it over to the Agentic AI Foundation (Linux Foundation). (sources: 17)
• Gemini (● yes): MCP connections in Gemini Enterprise’s workflow tool; in the app, via Spark (outside Europe). (sources: 37, 34)
• Microsoft 365 Copilot (● yes): MCP-compatible software added as actions in Copilot Studio. (sources: 22)
• Mistral Vibe (formerly Le Chat) (● yes): Custom MCP connectors from the Team plan upwards. (sources: 40, 41)
• DeepSeek (○ no or not documented): Nothing documented for the app. (sources: 48)
• Meta Muse (○ no or not documented): No officially documented MCP support to date. (sources: 23)
• Grok (◐ partial): MCP connections offered in the developer offering; not documented in the app. (sources: 27)

When the vendor changes model, who decides?

13 February 2026: OpenAI retires GPT-4o, GPT-4.1, GPT-4.1 mini and o4-mini from ChatGPT. (sources: 1, 2)

Teams that had built their workflows on these models had to follow the vendor’s schedule. For developers, further shutdowns are scheduled, including o4-mini on 23 October 2026.

Illustration: in EWE, one command is enough to change model; memory and skills are kept.

EWE keeps memory, files and history on the company’s infrastructure

With an online assistant, every question, every file and every piece of context goes to the vendor, who decides where it is stored, for how long and with which sub-processors. EWE turns this around: it installs on your premises, and you decide what leaves, down to nothing at all.

Frequently asked questions about EWE

How does EWE protect data compared with ChatGPT?

EWE installs on your premises: memory, files and history stay on your infrastructure, and only the request goes to the chosen AI. By contrast, ChatGPT processes and stores data in OpenAI’s cloud; storage in Europe is only offered on the Enterprise and Edu plans. (sources: 3)

What is a sovereign alternative to ChatGPT Enterprise or Microsoft 365 Copilot?

EWE is an alternative installed on your premises: the agent, its memory and its files run on your infrastructure, with the AI of your choice. By contrast, ChatGPT and Microsoft 365 Copilot remain services hosted by their vendors; among the assistants compared, only Mistral’s Enterprise plan can also be deployed on-premise, with Mistral models only. (sources: 3, 18, 40)

Does EWE work with European AI models?

Yes: EWE uses Mistral’s models, hosted in the European Union by default, and can install open models on your premises. In practice, you choose the provider according to your confidentiality requirements, agent by agent. (sources: 42)

What if an AI provider retires a model or changes its terms?

You switch to another model with one command, memory and skills intact. Factually, OpenAI retired four models from ChatGPT on 13 February 2026; an AI installed on your premises, by contrast, cannot be taken away from you. (sources: 1, 2)
