"Which AI should I use?" This is the question most SMB leaders ask when they want to get started. The answer isn't simple, because all three major tools (ChatGPT, Claude, Microsoft Copilot) excel in different areas. In this article, we compare all three in detail so you don't waste time experimenting — you can pick the best one for your needs right away.
AI tools evolve quickly. This comparison reflects the state of things as of February 2026. Prices are given in Hungarian Forints for easier comparison (1 USD = approx. 390 HUF). Features and prices may change, but the main differences and our recommendations should remain valid for months to come.
The Three Contenders in Brief#
Here's each tool in one sentence:
- ChatGPT (OpenAI): The best known, the most versatile, the largest ecosystem. If you can only have one tool, make it this one.
- Claude (Anthropic): The best text quality, especially in Hungarian. If you write a lot, this is your tool.
- Microsoft Copilot: If your company uses Microsoft 365 (Word, Excel, Outlook, Teams), this is the simplest integration.
Now let's look at the details.
ChatGPT: The Swiss Army Knife#
Versions and Pricing#
| Version | Monthly fee | Best for |
|---|---|---|
| ChatGPT Free | HUF 0 | Trying it out, occasional use |
| ChatGPT Plus | ~HUF 8,000/person | Individual users, daily regular use |
| ChatGPT Team | ~HUF 10,000/person | Teams (2+ people), business data privacy |
| ChatGPT Enterprise | Custom pricing | 50+ person companies, admin dashboard, SSO |
Strengths#
Versatility. ChatGPT is good at virtually everything: text writing, analysis, coding, image generation (DALL-E), file processing, web search. One tool that covers most needs.
Custom GPTs. Starting from the Plus version, you can create custom GPTs: upload your company data, set its personality, and get a purpose-built tool. For example, a "Proposal Writer GPT" that knows your pricing, services, and tone of voice. Or a "Newsletter Writer GPT" for the marketing team.
Massive ecosystem. Thousands of plugins, integrations, and third-party tools are built on it. Make.com, Zapier, Slack, Google Workspace: all connectable. If you want to automate, the ChatGPT API is the most widely used.
GPT Store. Browse Custom GPTs built by others: SEO analyzers, email writers, data analysts, HR assistants. You don't have to build everything yourself.
Weaknesses#
Hungarian language quality. Good, but not perfect. With longer texts, it sometimes gets tangled up, struggles with word order, and doesn't always understand idioms. Excellent for short, instruction-type tasks. For literary-quality text, Claude is better.
Data privacy in the free version. In the Free and Plus versions, your data may be used for AI training (can be turned off in settings, but it's on by default). Not an issue with Team and Enterprise versions.
Response quality fluctuation. Sometimes brilliant, sometimes superficial. The GPT-4o model is more consistent, but it occasionally falls back to older models.
Best For#
- General office work (emails, documents, summaries)
- File processing (PDF, Excel, image analysis)
- Building automations (API, integrations)
- Image generation (DALL-E integration)
- If you want one tool for everything

Claude: The Text Master#
Versions and Pricing#
| Version | Monthly fee | Best for |
|---|---|---|
| Claude Free | HUF 0 | Trying it out, limited use |
| Claude Pro | ~HUF 8,000/person | Individual users, daily use |
| Claude Team | ~HUF 12,000/person | Teams (2+ people), admin, business data privacy |
| Claude Enterprise | Custom pricing | Large enterprises, SSO, audit log |
Strengths#
Hungarian language quality. This is Claude's biggest advantage from an SMB perspective. Hungarian texts are more natural, word choice is more accurate, and tone-matching is better than ChatGPT. If you write a lot in Hungarian (proposals, marketing copy, client communication), Claude delivers noticeably better results.
Long document handling. Claude works with a 200,000 token context window. That's roughly 150,000 words — a complete book. You can load a 50-page contract and ask questions about it. Or upload 10 financial reports at once and request a comparative analysis. This works with ChatGPT too, but Claude is more consistent with long texts.
Data privacy. Anthropic (Claude's developer) specifically focuses on AI safety. With Claude Pro, your data is not used for training by default. This isn't just a promise — the company's business model is built on it.
Instruction following. If you give detailed, complex instructions (e.g., "write a 1,000-word article with this structure, in this tone, with these keywords"), Claude follows them more precisely. Fewer "going off script" moments.
We wrote about Claude Code, the developer tool, in more detail in the Claude Code in everyday business article.
Weaknesses#
Smaller ecosystem. No GPT Store, no built-in image generation, fewer third-party integrations. If you want to automate, the ChatGPT API is more widely supported.
No built-in web search. Claude can't search the internet in real-time (ChatGPT can). If you need fresh data, you'll need to handle that manually.
Less well-known. Your team has probably heard of ChatGPT, but not necessarily Claude. This means a bit more education is needed during implementation.
Best For#
- Hungarian-language text writing (proposals, marketing, emails)
- Long document analysis (contracts, reports, grant applications)
- Following detailed, complex instructions
- When data privacy is a top priority
- Coding and development (Claude Code)
Microsoft Copilot: The Office Extension#
Versions and Pricing#
| Version | Monthly fee | Best for |
|---|---|---|
| Copilot Free | HUF 0 | Trying it out, limited features |
| Copilot Pro | ~HUF 8,000/person | Individual users + M365 integration |
| Copilot for Microsoft 365 | ~HUF 12,000/person* | Teams, full Office integration |
*Available as an add-on to Microsoft 365 Business Standard/Premium, so the M365 fee (HUF 5,000-9,000/month per person) is on top of this.
Strengths#
Native Office integration. This is Copilot's real power. It works directly in Word, Excel, Outlook, Teams, and PowerPoint. No need to copy text between windows. Ask for a summary of a Teams meeting, and it appears in Teams. Ask for a chart from Excel data, and it places it in PowerPoint.
If you already use Microsoft. If your company already uses Microsoft 365 (and most Hungarian SMBs do), Copilot is the path of least resistance. No new tool to learn, no new interface to get familiar with.
Enterprise-grade data privacy. Microsoft 365 Copilot operates within your company's tenant. Your data stays in your M365 environment. This is the strongest enterprise security guarantee of the three tools.
Teams Meeting summaries. If you have a lot of meetings, this alone is worth it: Copilot automatically takes notes during Teams meetings, summarizes the main points, and highlights decisions and deadlines.
Weaknesses#
High total cost. If you don't already have an M365 subscription, Copilot is an expensive entry point. M365 Business Standard (~HUF 5,000/month per person) plus Copilot (~HUF 12,000/month per person) totals ~HUF 17,000/month per person. For a 10-person team, that's HUF 170,000/month.
Hungarian language. Copilot's Hungarian language quality is the weakest of the three. It works, but you can tell English is the primary language. Especially noticeable in text writing and creative tasks, where it falls behind ChatGPT and Claude.
Locked to the Microsoft ecosystem. If you use Google Workspace, Copilot isn't relevant. If you have a mixed environment (e.g., Google Drive + Outlook), Copilot only works on the Office side.
Less flexible. For custom prompt writing and following complex instructions, ChatGPT and Claude are better. Copilot is brilliant for simple tasks within Office, but more limited when you step outside that frame.
Best For#
- If your company already uses M365 and doesn't want to introduce a new tool
- Word documents, Excel analyses, PowerPoint presentations
- Automatic meeting notes in Teams
- Outlook email summaries and reply drafts
- If IT security is a top priority (enterprise tenant)

Which One Should You Pick? Specific Scenarios#
The table is useful, but the decision always depends on the specific company's situation. Here are the most common scenarios:
"I have a sales team, we write proposals and emails"#
Recommendation: Claude Pro or ChatGPT Plus
In proposal writing and client communication, text quality matters most. Claude's Hungarian texts are more natural and tone-matching is more precise. But if you also need to load files (Excel price lists, PDF specs), ChatGPT is more flexible. Both are good choices — try both for a week using your own proposals.
"We have lots of admin work, creating documents and reports"#
Recommendation: Microsoft Copilot (if you use M365) or ChatGPT Plus
If your team works in Word and Excel every day, Copilot is the most convenient: it helps right on the interface you're used to. If you don't have M365, or need it for more varied tasks, ChatGPT Plus is the better choice.
"We're a marketing team, we create content"#
Recommendation: Claude Pro (text) + ChatGPT Plus (images + analysis)
For content creation, Claude produces the best Hungarian text. But if you also want to generate images or do SEO analysis, ChatGPT is useful as a complementary tool. Most marketing teams we work with use both: Claude for writing, ChatGPT for everything that isn't text.
"I'm a solo operator, I need one tool for everything"#
Recommendation: ChatGPT Plus
If you can only have one subscription and need it for everything (email, proposals, analysis, images, search), ChatGPT Plus is the most versatile. Not the best at anything, but good enough at everything. For an SMB leader working alone or with a small team, this is the most practical choice.
"Data privacy is paramount, we're in a regulated industry"#
Recommendation: Microsoft Copilot for M365 or Claude Team
If you work in healthcare, finance, or legal, data privacy takes priority. Copilot for M365 stores data within your own Microsoft tenant, which is the strongest guarantee. Claude Team is also a good choice because Anthropic doesn't use your data for training by default.
"We're a development team, we need it for coding too"#
Recommendation: Claude Pro (Claude Code) + GitHub Copilot
For coding, Claude is currently the strongest, especially with the Claude Code tool. GitHub Copilot (a Microsoft product, but independent from ChatGPT) is also excellent for code completion. We wrote about this in detail in the Claude Code in everyday business article.
Most companies we work with use 2 tools in parallel. The most common combination: ChatGPT Plus (for general tasks) + Claude Pro (for text writing). That's HUF 16,000/month per person, and it covers most needs. Don't think "either/or" — think "which is best for what."
How to Test in 1 Week#
You don't have to decide blindly. Here's how to test all three tools in just 5 business days:
Monday: Register for all three free versions
Signing up for ChatGPT Free, Claude Free, and Copilot Free takes 10 minutes total. No commitment, no credit card.
Tuesday: Same task on all three
Pick a specific task from your daily work (e.g., writing a proposal, replying to an email, summarizing a report). Do it on all three with the same prompt. Compare the results: which was best in quality, speed, and usability.
Wednesday: Hungarian text writing test
Ask all three for a 300-word Hungarian text on your company's topic. Which sounds the most natural? Which would need the least editing?
Thursday: Document analysis test
Upload a PDF (e.g., a report or contract) into all three and ask for a summary. Which highlights the key points? Which is accurate? Which handles Hungarian text better?
Friday: Decision
Based on the week's experience, select the tool (or tools) that worked best for your tasks. Subscribe to the paid version and start using it regularly.
Cost Comparison for a 10-Person Team#
Because in the end, this matters too. Let's see how much it costs when 10 people use each tool:
| Configuration | Monthly cost (10 people) | What you get |
|---|---|---|
| ChatGPT Plus (10 people) | HUF 80,000 | General AI, files, images, Custom GPT |
| ChatGPT Team (10 people) | HUF 100,000 | Same + business data privacy, admin |
| Claude Pro (10 people) | HUF 80,000 | Best text, large documents |
| Claude Team (10 people) | HUF 120,000 | Same + business features, admin |
| Copilot Pro (10 people) | HUF 80,000 + M365 | Office integration (M365 separate!) |
| Copilot M365 (10 people) | HUF 120,000 + M365 | Full Office AI (M365 fee: +50-90K HUF) |
| ChatGPT Plus + Claude Pro (10 people) | HUF 160,000 | The two strongest, covers everything |
If 10 people each save 30 minutes daily with AI, that's 100 hours saved per month. At an average hourly cost of HUF 3,000, that's HUF 300,000 worth of freed-up capacity per month. Any of the above configurations easily pays for itself in the first month. The question isn't "is it worth it" — it's "which one will get you the biggest impact."
What to Expect in the Second Half of 2026#
The AI market is changing fast. These trends are already visible and will become increasingly important in the coming months:
Prices will continue to drop. Competition is driving prices down. In 2024, ChatGPT Plus was $20/month — it still is, but you get much more for it. Claude and Copilot also offer increasingly better value. By end of 2026, some of today's paid features may become free.
Hungarian language will keep improving. All three tools continuously improve non-English language support. In 2024, Hungarian text often sounded odd. In 2026, it's natural. In the second half, this will be further refined, especially for specialized terminology (legal, financial, technical).
Integrations will expand. Today, you still need to copy-paste in many places. But more and more software is building native AI: Notion, Slack, HubSpot, Salesforce have all started down this path. By end of 2026, most business software will have built-in AI, and the question won't be "should I use AI?" but "which built-in AI should I use?"
Agent-type AI will emerge. This is the next big step: AI not only answers your questions but independently executes tasks. For example: "Prepare a monthly report from sales data and email it to management." Today, you do this with AI's help. Soon, AI will do it on its own, under your supervision.
What's True for All Three#
Before you decide, it's important to know what's tool-independent:
An AI tool is only as good as how well you use it. All three can produce both amazing and catastrophic results. The difference lies in prompt quality. If you learn to give good instructions, you'll get good results with any of them. If you don't, you won't with any.
Human review is always needed. Whichever tool you use, always check the output. AI can make mistakes, misunderstand context, or provide outdated information. AI is an assistant, not a decision-maker.
Data privacy is your responsibility. All three tools offer better data privacy in their paid versions than the free ones. But internal regulation (what data can be entered) is your job. In the context of the EU AI Act, this is also a legal obligation.
All three evolve quickly. What I write today will be partially outdated in 6 months. The core insights (which is best for what) won't change, but the details will. It's worth checking quarterly for relevant updates.
Summary: In 3 Sentences#
ChatGPT: If you can only have one tool, this should be it. The most versatile, the largest ecosystem, good enough for everything.
Claude: If Hungarian text writing or document analysis is your main need, Claude is the best. Especially for proposals, marketing, and client communication.
Copilot: If your company uses Microsoft 365 and the goal is improving efficiency within Office, Copilot is the most convenient path.
If you still can't decide, book a 30-minute consultation. We'll discuss your tasks and which tool would deliver the highest ROI. And if you've already decided and want to roll it out to your team, our AI tool implementation service supports the entire process: from tool selection to team training.
