What counts as an AI chatbot company?
In this guide, an AI chatbot company is one that trains its own large language model (LLM) and sells a chat assistant built on it. That is different from a customer-service chatbot vendor, which usually rents a model from one of these labs.
The difference matters when you buy. Model makers decide what the AI can do, how much it costs and how your data is handled. Platform vendors add workflows, inboxes and integrations on top.

The leading AI chatbot companies, one by one
1. OpenAI (ChatGPT)
OpenAI started the boom with ChatGPT in late 2022 and still leads on usage. ChatGPT offers Free, Go, Plus and Pro plans for individuals, plus Business and Enterprise plans for teams. Its GPT models also power many third-party apps through the OpenAI API.
Limitations: the cheaper plans have message caps on the newest models, and plan details change often. Check the official ChatGPT pricing page before you subscribe.
2. Google (Gemini)
Google renamed Bard to Gemini in 2024. Gemini now sits inside Google Search, Gmail, Docs and Android phones. The Google AI plans run from Free to AI Plus ($4.99), AI Pro ($19.99) and AI Ultra (from $99.99 a month).
Best for people who already live in Google Workspace. Watch out for features that roll out to the US first.
3. Anthropic (Claude)
Anthropic was founded in 2021 by former OpenAI staff and focuses on AI safety research. Its Claude assistant is popular for long documents, careful writing and coding. According to the Claude pricing page, Pro costs $20 a month ($17 billed yearly), and Max starts at $100.
Limitations: usage limits reset over time windows, so heavy users can hit caps on Pro.
4. Microsoft (Copilot)
Microsoft turned Bing Chat into Copilot in late 2023. The consumer Copilot app is free, and Microsoft 365 Premium bundles Office apps with higher Copilot limits for $19.99 a month. Microsoft 365 Copilot for business is a separate per-user add-on.
Copilot uses OpenAI models plus Microsoft’s own models. It is strongest when you want AI inside Word, Excel, Outlook and Teams.
5. Meta (Meta AI and Llama)
Meta AI is free inside WhatsApp, Instagram, Messenger and Facebook. Meta also releases Llama models with open weights, which other companies can run on their own servers.
Watch out: chats inside Meta’s apps are tied to your social accounts, so read the privacy settings first.
6. xAI (Grok)
xAI, Elon Musk’s AI company, merged with X in 2025 and is now part of SpaceX. Grok is built into X and also has standalone apps. SuperGrok costs about $30 a month, and a higher Heavy tier costs much more.
Grok’s selling point is live access to posts on X. Its weak spot is consistency: it has faced repeated criticism over offensive or inaccurate answers.
7. Mistral AI (Le Chat)
Mistral AI is a Paris-based company and Europe’s best-known LLM maker. Its Le Chat assistant has a free tier and a Pro plan of about $14.99 a month. Many of its models are released with open weights.
It is a good choice for EU businesses that want a European provider. Its consumer app is less polished than ChatGPT or Gemini.
8. DeepSeek
DeepSeek is a Chinese lab that surprised the industry in early 2025 with strong, low-cost models. Its app is free, and its open-weight models are widely used by developers.
Who should not use it: businesses with strict data rules. Its servers are in China, and some governments have restricted its use on official devices.
9. Perplexity
Perplexity is an AI search engine more than a model maker. It routes questions to several models and shows sources for each answer. It is useful for research, but it relies on other companies’ models.
Which AI chatbot company should you choose?
Use this quick decision guide instead of picking the biggest name:
- You want one all-round assistant: ChatGPT Plus or Gemini (AI Pro).
- You write long reports or code: Claude Pro.
- Your work happens in Microsoft Office: Copilot via Microsoft 365.
- You need EU data hosting: Mistral Le Chat.
- You want free AI in messaging apps: Meta AI.
- You are a developer on a budget: open-weight models from Meta, Mistral or DeepSeek.
- You want a bot on your website: pick a chatbot platform instead. See top chatbot companies like Intercom and Zendesk.
Five things to check before you pay
- Usage caps: “unlimited” plans still limit the newest models.
- Data training: check whether your chats are used to train models and how to opt out.
- Team plans: business plans usually exclude your data from training by default.
- Yearly lock-in: annual billing saves money but is hard to refund.
- Integrations: the best model is useless if it does not connect to your tools.
What changed since 2024
The 2024 version of this page listed Google Bard and Microsoft Power Virtual Agents. Both names are retired. Bard is now Gemini, and Power Virtual Agents became Microsoft Copilot Studio.
The market also shifted from “chatbots” to “AI agents” that can browse, run code and complete tasks. Prices for standard plans stayed near $20, but new premium tiers appeared at $100–$300 a month.
Limitations of AI chatbots in general
- They can still make up facts (“hallucinate”), so check anything important.
- Answers vary between runs, which makes them hard to audit.
- Model names and limits change every few months.
- Sensitive data should not go into consumer plans.
For marketing teams, AI chatbots work best as helpers inside a clear plan. Our guide on how to create a digital marketing strategy shows where they fit.
