Personal AI agent vs ChatGPT vs Copilot: choose
Short answer
ChatGPT suits analysis, writing and work with files. Microsoft 365 Copilot is the natural start for a company working in Word, Excel, Outlook and Teams. A dedicated agent makes sense when a repeatable process runs through unusual systems and needs its own rules, approvals and history of actions. Start with a ready tool. ChatGPT Business costs $20 per person with annual billing.

Three tools in one table
| Axis | ChatGPT | Microsoft 365 Copilot | A dedicated agent |
|---|---|---|---|
| Main environment | ChatGPT, files and connected apps | Microsoft 365 apps and data | Chosen systems, a server and channels |
| Best start | Analysis, writing, search | Work in the Microsoft suite | A repeatable process of one role |
| Actions | Features of the product and apps | Features of the suite and the administrator's agents | A list: read, draft, act after approval, forbidden |
| History | The product's rules and controls | Controls, audit and tenant rules | Its own process history |
| Purchase | Subscription, from $20 per person | A licence tied to Microsoft 365 | A build plus running costs |
The comparison is about the work environment, permissions and responsibility. It is not a ranking of model quality.
Many companies combine these routes. The team works in ChatGPT or Copilot, and one repeatable process, for example preparing quotes from several systems, gets a dedicated agent. Such a split usually costs less than trying to do everything with one tool.
When to start with ChatGPT
ChatGPT is a sensible start when the work fits into analysis, writing, files and connected apps. Features and limits depend on the plan, so check the terms on the ChatGPT Business pricing page. A separate system has no justification when it would only write, analyse files or search for information in a similar window.
When Microsoft 365 Copilot is the right choice
Copilot is the natural choice when the company already works with Microsoft 365 documents, mail, meetings and permissions. The data protection documentation describes how it works within the existing permissions, labels, retention and audit. Microsoft states that prompts, responses and data from Microsoft Graph do not train the foundation models. The administrator is still responsible for access, apps and agents.
What you buy in a dedicated agent
A dedicated agent is a configured process with its own permissions and a record of actions.
- Named sources it may read
- Tools and actions available for the specific task
- Levels: read, draft, act after approval
- Situations in which work stops and goes to a person
- Memory with a set retention
- A history of sources, decisions and actions
- A person responsible for updates, failures and costs
Three scenarios for the choice
A founder analyses documents, writes and looks things up
ChatGPT or Claude
from $20 per person
A director works in Outlook, Teams, Word and Excel
Microsoft 365 Copilot
by plan
A daily review from five sources, custom APIs, every action after approval
an agent for the process
from €3,000
In the first two scenarios we help with a team rollout from €1,150 net: accounts, rules for working with data and training on real tasks. The choice between ChatGPT and Claude is covered in Claude or ChatGPT for business.
Cost and day-to-day work

Per person a month with annual billing, $25 with monthly billing. A team rollout from €1,150.
Microsoft 365 Copilot
by plan
The price depends on the market and the base plan. Count the base Microsoft 365 plan in the full budget.
A dedicated agent
from €3,000
An agent for one process. On top come the server, the models and care, counted before the contract.
A subscription includes some elements that you pay for separately with a dedicated agent. The comparison should cover a whole year and the time of the person who uses the system. We count the full Copilot budget in the article on Copilot pricing.
Permissions and approvals
Whatever you choose, settle which sources the tool sees, which actions it may take, what needs approval and where it records its history. Contracts, payments, publishing, deleting files, changing permissions and mass communication should be switched off or need separate approval.
Start with a ready product that fits the company's data and apps. Consider a dedicated agent for a process that needs switching between systems, manual workarounds or its own approval rules. The free process review can end with a simple recommendation: stay with ChatGPT, Copilot or another ready tool.
„I already use AI.”
Your people too. Just no rules.
From our conversations with companies
5 na 10 employees paste sensitive data into private AI accounts: contracts, invoices, customer data.
In ESET survey (2026)
1 na 10 admits this in the survey.
Customer data pasted into a private AI account without an data processing agreement is a violation of the GDPR.
Don't worry, we won't tell anyone :)
What do we see in companies that "already use"
- Only ChatGPT or Claude accounts, without plugins, skills, integrations and MCP servers with company tools.
- Company programs are not connected to AI. People still click through systems and Excel, and enter chat data manually.
- Lack of company standards: everyone writes instructions in their own way, no one shares what works.
- No rules for personal data, GDPR and company secrets.
- No limits and no visibility: no one knows who uses AI, how much and for what.
62% Polish employees use AI at work · 27% companies have written rules for working with AI.

ChatGPT or Claude space review
Accounts, permissions, rules for working with data and 5 tasks set for the team. 1 day.
€450 net
Company accounts, rules of working with data and team training in 2 weeks, from €1,150 net.View implementation for the team →
„Is my data safe?”
Yes. You choose where they go: from your company account to the model on your server.
00Employee's private account
Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.
01ChatGPT or Claude corporate account
The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.
02API with zero retention (ZDR)
The provider processes the request and does not save anything. It requires his consent, we prepare the application together.
03Processing in the EU
Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.
04Model at your place
The open model runs on your server or in your cloud in the EU. The data does not go outside the company.
What we do with every implementation
- Confidentiality agreement and data processing agreement before we receive any data.
- You choose the cases for the prototype and we anonymize them upon request.
- The data stays in the EU and we delete it after the test.
- Corporate accounts with an administrator on your side.
When data cannot leave the company
The open model runs on your server or in your cloud in the EU. To choose from:
- White-tailed eagle
- Polish model, SpeakLeash and ACK Cyfronet AGH
- PLLUM
- Polish model, HIVE consortium commissioned by the Ministry of Digitization
- Qwen
- Alibaba
- GLM
- Zhipu AI
- DeepSeek
- DeepSeek
We select a model for the task and check it on your cases. We run it, tune it and maintain it.

Do you have a lot of your own data? We will fine-tune the small model.
- 1 Your examples
- 2 tuning
- 3 test on new cases
- 4 model at your place
When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.
Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

Worked example · Scenario
How we count the payback: board meeting notes
We run the same count for your team's tasks: how many there are, how long they take, what the licences cost.
€1,309
a month for writing notes after 50 meetings
Payback: 1.4 mo.
Our assumptions are 45 minutes for the note from a board meeting and the update of the task list, and checking in 25% of the old time. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Licence: ChatGPT Business or Claude Team at 20 USD per person a month on annual billing, about €17.85 at the ECB rate of 1.1205 USD per euro on 22 October 2026. We count the whole licence against notes here, although the team also uses it for other work. Rollout: from €1,150 for up to 10 people, from €2,300 for 11 to 40 people.

A dedicated agent or ChatGPT?
Start with ChatGPT if the work fits into analysis, writing, files and connected apps. A dedicated agent makes sense for a repeatable process that runs through unusual systems, with its own rules and approvals.
When should we choose Microsoft 365 Copilot?
When the company works with Microsoft 365 documents, mail, meetings and permissions. Copilot works within the existing permissions, labels and retention. You check the price in the company tenant on the day you buy.
How much does a ChatGPT, Claude or Copilot rollout cost?
A rollout for a team of up to 10 people costs from €1,150 net at Syntalith, and up to 40 people from €2,300. The company buys licences directly from the vendor. An agent for one process costs from €3,000 net.
Which actions should no assistant take by itself?
Signing a contract, a payment, a public post, deleting files, changing permissions and mass communication. These actions should be switched off or need a person's separate approval.
