But most of them are using completely the wrong tool for the wrong job. They're cutting bread with a spoon and then wondering why it's such hard work. I went through it myself at the start. When we at LK Media began implementing AI, it was pure chaos. We paid for pointless subscriptions, tested through the night, sometimes cheered and quite often cursed like sailors.
Today I know where to reach. Are you looking for the best AI chatbots for your business, or just a companion for experiments at home? This is the reality of the market in 2026. No marketing fluff.
The quick summary
Can't be bothered to read the whole thing? Fair enough. In a nutshell it goes like this: for writing copy and flawless Czech, Claude 4.6 absolutely rules — it even beats ChatGPT. The best free AI chatbots for Czech right now are Gemini (huge limits) and DeepSeek (you get the full model for free, but watch out for the Chinese servers). Anyone who needs research and facts has to go to Perplexity, because it doesn't make things up and it cites sources. And for the corporate world, where GDPR is the name of the game, you want Copilot or the European Mistral. For premium versions you'll pay roughly $20 a month these days.
9 AI chatbots that handle Czech (and how they really stack up)
The market has shuffled incredibly since last year. Forget the idea that OpenAI is all there is.
ChatGPT (OpenAI) — the all-rounder that sometimes bores you
Good old ChatGPT now runs on the GPT-5.4 model. Over a billion people fire it up monthly (MAU) and it's still an incredible all-rounder. They recently poured in a "computer use" feature, which scored 75% on the OSWorld benchmark. It sounds complicated, but in practice it means the chatbot can actually move your mouse and click around your computer.
Its Czech is grammatically perfect. The style is another story. In a blind test (a survey by the magazine Živě.cz, judged by 134 people) ChatGPT won just one of 8 rounds. It still sounds somehow... robotic. You have to hammer it with a very strict prompt to stop it writing like a bureaucrat. The free version is fine, the Go version costs $8. Plus costs $20 and for connoisseurs there's Pro at $200. A Swiss army knife. You can open a can with it, but you won't carve a roast.
You know what happened in February 2026 in America? OpenAI quietly rolled ads into the free version there. You type in a question about a recipe and before the bot spits it out, you have to sit through a visual banner for a new blender or a sponsored link. It's only creeping into Europe so far, but it clearly shows where this market is inexorably heading. The era of "everything free and no nagging" is definitively ending. The future is uncompromising: either you pull twenty bucks a month out of your wallet for premium access, or you'll be staring at ads like on commercial TV. Nothing in between. For businesses it means one thing – if your people run on free versions, they'll soon spend more time clicking away sponsored products than doing actual productive work.
Claude (Anthropic) — my absolute love
If I could take just one single tool to a desert island, it's Claude. The Opus 4.6 and Sonnet 4.6 models are currently the best this planet has to offer. I'm probably a little in love with it (and I'm not ashamed of it). In the aforementioned Živě.cz test it comfortably won 4 of 8 rounds and it sits steadily at the top of the global Chatbot Arena.
The tool simply understands language. It writes so well that you have absolutely no chance of telling it was generated by artificial intelligence. It swallows up to 1 million tokens at once — that's roughly 15 average-length books. In programming (it scored 80.9% on the SWE-bench test) it flat-out outclasses most of the junior developers I know. And thanks to MCP (Model Context Protocol) I can hook it up directly to our company data and it sucks context out of it. Anthropic was actually founded by defectors from OpenAI, and this revenge is really working out for them. The base is free, the Pro version costs $20 and the Max version $100–200. If you write copy or build code, look no further.
Personally, though, what got me most are the Claude Code and Projects features that Anthropic recently rolled out. That's the real game-changer for teams. In Projects you simply create a closed workspace, upload your brand's detailed style guide, past successful campaigns, complete documentation and chunks of source code. Claude reads it all diligently and from that moment works like your new, highly competent colleague who has everything at their fingertips and remembers every previous decision you made. That's exactly why giants like Shopify and Airbnb are now switching en masse from ChatGPT to Claude. They found that when they put Claude Code in the hands of their engineers and marketers, the tool genuinely walks through their vast repositories, proposes logical edits itself and fixes bugs in the context of the whole huge project, not just in one isolated file. For small and mid-sized teams it's like gaining a top-tier digital colleague you pay barely twenty bucks a month.
Gemini (Google) and Copilot (Microsoft) — the corporate war
Google has stepped up incredibly with Gemini this year. The Gemini 3.1 Pro model has such an absurd memory that you can upload an hour-long video meeting, five annual reports, and it remembers it all. Interest in it in the Czech Republic grew by 399%. That's because it's wired straight into Google Workspace. This year they added the Veo 3.1 model for generating video right inside the chat and, crucially, cut hallucinations from last year's 88% to 50%. The free version is generous, AI Pro costs $19.99 and Ultra around $42.
There's one thing you have to keep an eye on with Gemini, though. Sure, they boast that they've dragged hallucinations from last year's insane numbers down to today's 50%. Sounds like progress, right? But try translating that into plain terms and everyday practice. It really means that every second fact, every second number or historical name this chatbot confidently serves up in your text can be complete nonsense. It just sucked it out of thin air to please you and not leave a blank. When Gemini does research for an important client presentation or pulls data into a report for your boss, you have to sit over it like a hawk and manually verify every other sentence via a classic search engine. Otherwise you'll embarrass yourself horribly in the meeting.
Microsoft goes at it through security with Copilot. It runs on OpenAI's GPT-4o. If you have a corporate license, the data stays in the EU and nobody trains on it. For public authorities and corporations, a must. In David Kapler's independent quality test it came second. It costs $20, the Enterprise version $30.
Perplexity — this will kill classic Google for you
For finding facts I use nothing else. Perplexity has 45 million users today. It's not a chatterbox, it's a search engine. You ask, it scours the web and writes an answer with clickable citations. The Deep Research feature can produce the groundwork for a market analysis in a few minutes. In the paid version ($20) you also switch the models running under the hood. Enterprise costs $40–325.
The hard truth is that if you play in the higher league and have the budget for it, this year Perplexity introduced the Enterprise Max plan. It costs a brutal $325 per seat, but you get the so-called Perplexity Computer for it. This is no longer just a smart search engine, it's pure agentic automation taken to the extreme. Imagine having 19 different top-tier AI models under the hood in a single interface. You give it a complex task, for example "do a deep analysis of the commercial real-estate market in Brno, compare it with the trend in Prague over the last three years and find hidden investment opportunities", and Perplexity Computer picks for itself which model is best for crunching numbers, which for reading through the land registry and which for neatly writing up the final result. It flips between those models in the background in a flash, tasks them itself, checks their outputs and, after an hour, spits out a finished, formatted document at the level of a senior analyst from a Big Four firm.
DeepSeek — the cheap Chinese dragon
Damn, I have mixed feelings about this one. DeepSeek V3.2 is up there on performance, but it's COMPLETELY free. No limits. The API for developers costs a laughable $0.42 per million tokens. The competition is ten times pricier. The catch? China. Privacy protection is zero. Before you upload code or company strategy there, slap yourself. But for school reports, it's a gem.
Mistral (Le Chat)
The French. They have servers in Paris and meet strict GDPR. It costs $14.99. Look, with Mistral I'm not entirely sure how much the base model is actually used in the Czech Republic among ordinary people, but for companies paranoid about American servers it's a lifesaver.
Grok and Meta AI — the rebel and the social assistant
Elon Musk's Grok 4.1 has real-time data from the X network and handles 2 million tokens. It likes to make things up, it's meant to be "anti-woke" and it costs $30. Meta AI with the Llama 4 model is integrated into WhatsApp for $10. But in the EU it's a pain because of the legislation and you often have to turn on a VPN. I'd rather avoid both in a corporate setting.
The comparison table (the essentials)
Chatbot | Price (Free/Premium) | Czech | Best for | Memory |
Claude | Free / $20 | ⭐⭐⭐⭐⭐ | Copywriting, code | 1 million tokens |
ChatGPT | Free / $20 | ⭐⭐⭐⭐ | General use | 1 million tokens |
Gemini | Free / $19.99 | ⭐⭐⭐⭐ | Google Workspace | Millions of tokens |
Copilot | Free / $20 | ⭐⭐⭐⭐ | Microsoft 365 | 128k tokens |
Perplexity | Free / $20 | ⭐⭐⭐⭐½ | Research, analysis | Depends on the model |
DeepSeek | FREE, no limits | ⭐⭐⭐½ | Low budget | 128k tokens |
Which AI chatbot is free?
You don't want to pull out your credit card. Fair enough. If you type "free AI online" into Google, a ton of junk pops up. But realistically?
Gemini gives you the most for nothing. Google's access to the large-memory model is incredibly generous. If you need to polish Czech copy and emails, go for the free version of Claude. After a few messages it'll kick you out and you'll have to wait a couple of hours, but the output is so good you'll forgive it. Perplexity in its base form is completely enough for everyday information hunting, for free. And DeepSeek released the very best fully free — again, though, I'll say it, only for unimportant data.
Personally? I combine free Perplexity for searching and free Claude for writing.
How we pick tools for clients (a decision matrix)
Here's how it usually goes with us: a client comes to me saying they want to start writing articles, newsletters and emails in the company. I push Claude on them straight away. Nothing beats it for Czech style.
When their IT department then chimes in that they need to speed up development, we deploy Claude Code or GitHub Copilot for them. As soon as the CFO comes to me, someone who lives in spreadsheets and worries about data, we uncompromisingly order Copilot for Microsoft 365, because they have it in the EU and it saves them hours in Excel. For market analysis we fire up Perplexity. We build customer support via the API on ChatGPT (which, by the way, we do very often). And when a student comes along saying they really have no money, I show them DeepSeek.
The pitfalls: Shadow AI, security and lying
This gives IT directors hives.
The data is clear — 57% of employees routinely copy sensitive company data into unapproved AI tools (data: Microsoft AI Diffusion Report). It's called Shadow AI. An accountant takes a spreadsheet of salaries, drops it into free ChatGPT, asks for a nice chart, and in that instant an American model is training on your company's salaries. That's exactly why companies are switching to the aforementioned Mistral (Paris) or paid Copilot.
And then there's the notorious making-things-up. AI lies and looks perfectly self-assured doing it. GPT-5.4 hallucinates in about 22% of trickier queries. Gemini 3.1 is at 50%. Grok makes up even more. Always — always! — ask for sources.
How much you'll pay for AI a year — a price calculator
I hear this all the time in consultations. "Lucie, are we supposed to pay for yet another subscription? We already pay for Office, for the accounting system, for graphics, for hosting..." So let's talk about real numbers, so we're clear on it and not making it up as we go. How much will this fun really cost you a year?
Free tier ($0 a year)
You run on free ChatGPT, occasionally fire up Gemini. It doesn't cost you a cent. Great. But you pay another way – with your time and your nerves. You keep hitting invisible message limits, it cuts you off halfway through an important task, and soon (as I said in the intro) annoying ads will start popping up at you. For a student it's a great starting point, but the moment you need reliability for everyday business, you'll sooner or later hit a hard wall with the free option.
One premium tool (~$240 a year)
You pick one main tool. Say Claude Pro or ChatGPT Plus. It costs you roughly twenty bucks a month, so about $240 over a year. Does that sum make you queasy? Then put it in context. For the price of one nicer dinner out with friends a month, you have unlimited access to the absolute best artificial intelligence in the world. To an assistant who never sleeps, never takes sick leave, never talks back and writes dozens of emails a day for you. Try hiring a live part-timer for twenty bucks a month. Good luck.
A multi-AI stack for pros (~$780 a year)
This is the option for those who take digitalization seriously and AI genuinely puts food on their table. You pay for Claude for premium copy and coding, Perplexity for deep research, and on top of that you have Copilot paid for within your company's Office suite for safely handling sensitive data. Monthly you're flying at around sixty-five bucks, which comes to some $780 a year per head. Sounds like a lot of money, I know. But from our data we clearly see that this "stack" saves an average manager roughly 10 to 15 hours of mind-numbing routine work a month. Just try converting that to your usual hourly rate. You'll suddenly find these tools pay for themselves financially before you can even blink.
Trends 2026
Artificial intelligence stopped being just a chat window long ago. If you treat it as merely a better calculator for text, you'll hit a hard wall.
This year AI agents are steamrolling everything. You no longer chat. You give a command ("Process the invoices from my email and drop them into the accounting system") and the agent simply does it itself. On top of that came MCP (Model Context Protocol). Thanks to it you connect AI to your Slack or company drive, so the chatbot knows your internal policies. Ads are starting to pop up at us from the free versions (servers cost something, right). And nobody runs just one tool anymore. Claude writes the code, Perplexity finds the documentation, GPT checks it. A multi-AI workflow.
But the absolute biggest turning point happening this year, the one changing the rules of the game, is so-called "Computer Use". The GPT-5.4 model no longer needs you to serve everything up to it on a silver platter in the chat window. It simply knows how to control your computer. On the demanding OSWorld benchmark, which precisely tests an AI's ability to actually work in an operating system, GPT-5.4 hit an incredible score of 75%. Just for comparison – the average human scores 72% on this test. AI is now demonstrably better at clicking around a computer than your auntie from accounting.
What does that mean in practice? In the morning you come to work, sit at your desk and tell the chatbot: "Go through my emails from yesterday, download all the PDF invoices from messages from suppliers, open our accounting program, create a new card for each invoice and copy in the amounts and reference numbers." And then you just watch the monitor open-mouthed as the mouse runs across it on its own, browser windows open, forms fill in and programs launch. You can drink your coffee and read the news while it does.
Hand in hand with that goes the enormous memory. A context window of 1 million tokens (and more) has become the absolute standard, and it means one thing. You no longer have to laboriously and tediously explain to the AI how things work at your company. You simply take your entire company wiki, all the security policies, the onboarding manuals for newcomers, a year's worth of customer communication history, and upload it all at once in one big bundle. The AI reads it in three seconds, understands the connections, and from that moment thinks and answers in the context of your whole company.
5 of my tips for Czech
You can have the most expensive model paid for, but if you give it a lousy prompt, it spits out lousy text.
- Role. Never start with "Write me". Give it context.
Sample prompt: "You are a senior B2B copywriter for a logistics company. Your tone is cheeky, direct and highly expert. Write me..."
- Clichés out. AI loves filler. In my prompts I flatly ban phrases.
Sample prompt: "In your text, absolutely leave out phrases like 'in today's world', 'in conclusion it can be said' and 'it's important to realize'. Get straight to the point."
- Examples. Copy it two paragraphs of your own text. Let it see your style.
Sample prompt: "Write a new LinkedIn post. Use exactly the same sentence structure and specific humor as in my sample text here: [paste your old text]."
- Iteration. Don't expect perfection right away. Let it write a skeleton. Criticize it. Have it rewrite it.
Sample prompt: "This is too boring, dry and formal. Rewrite the same text, cut it by half and add a bit of healthy sarcasm."
- Context. The more information you give it up front, the less nonsense it'll make up.
Sample prompt: "You're writing an email to a client who's owed us $2,000 for two months. We've already called three times. We want the money, but we don't want to annoy them, they're a VIP. Propose a payment schedule."
Conclusion: what now?
Ninety percent of companies want AI this year. Most buy one tool across the board, people stop using it within a month, and management writes it off as a loss.
At LK Media we don't make rocket science of it. We build AI assistants for clients tailored precisely to their needs. We find the places where you're burning money and time, and put a robot there. Thanks to the right AI workflow, one of our clients cut the time from a customer's visit to sending out a quote from 5 weeks to 1 hour. From five weeks to an hour. You read that right.
If you feel this train is leaving without you, don't force it. We can arrange an introductory consultation where I'll show you practical tips for your specific company, so you know exactly where to reach. And if you'd rather play and create, take a look at our AI video course. We teach things there that you probably never even dreamed of.
FAQ
Which AI is the best in 2026?
There's no single winner. Writing and coding = Claude 4.6. Research = Perplexity. An all-rounder for everything = ChatGPT with GPT-5.4.
Which AI chatbot is free and handles Czech?
The most generous free tier with big limits is Google Gemini. Completely free is the Chinese DeepSeek V3.2 (but beware of your data). Claude and ChatGPT have free versions too, they just cut you off sooner.
How much does ChatGPT cost per month?
Plus comes to $20 a month. There's also a stripped-down Go plan for $8.
Is it safe to use DeepSeek?
For generating little poems or translating a public article from CNN? Sure. For company code, contracts or client data? Not a chance. The operator sits in China.
Which chatbot is best for businesses?
For companies on Microsoft I recommend Copilot (because of the EU servers). For companies on Google Workspace, Gemini is a good fit. And if you want to write copy that sells, buy licenses for Claude Pro.
