Best AI chatbots for businesses in 2025

You are probably already using an AI chatbot.


But is it the best one?


We have compared the best AI chatbots for business in 2025.


Please note that in this comparison, our ranking is based on the best usage of AI chatbots for businesses, not on the underlying LLM model itself (if you are curious about this, read our articles on LLM evaluations). Below, the tools are assessed based on usability, features, and pricing.


Best AI chatbots for businesses 👇🏼



ChatGPT AI chatbot interface

ChatGPT offers a highly intuitive interface with support for text, voice, and image input. Features like "Projects" for organizing conversations and a phone service for voice interaction improve accessibility. It loses a point for occasional interface limitations, such as difficulty managing complex workflows.


Its LLMs (GPT-4o)  is best in class on several benchmarks. GPT-4o scores highly across benchmarks like MMLU (80.5%) and HumanEval (90.2%), showcasing strong reasoning and coding capabilities. Its multilingual performance is competitive but slightly behind Claude. However, its context window is limited to 128,000 tokens, which can be restrictive for handling large-scale inputs compared to Claude.


With a free plan, $20/month for Plus, and $200/month for Pro, ChatGPT offers scalability for individual and enterprise use. It loses points for high pricing at the Pro tier compared to competitors with similar capabilities.


Ayfie AI chatbot interface

Ayfie’s interface is simple and easy to use. The platform is designed for document search and management. 


Key features include smart document classification, generative AI for interactive engagement, and flexible deployment options (SaaS, hybrid, cloud). A highly functional option for industries like legal, technical, and insurance.


Ayfie is multimodular and the user can use different LLMs based on their liking, including GPT-4o, Claude 3.5 Sonnet, Gemini, Grok, and more.


Ayfie’s customizable pricing plans are a strength, but the lack of upfront transparency and potential high costs for advanced features make it less accessible for smaller businesses.



Claude AI chatbot interface

Claude’s interface is designed for long, complex conversations and includes features like "Artifacts" for document and dashboard creation. However, daily message limits in the free version may constrain some users, reducing its usability score.


Multimodal input, extended context windows, and "computer use" for desktop interaction make Claude a powerful tool. Experimental features are still being refined, which slightly impacts its overall feature score.


Its LLM (Claude 3.5 Sonnet) is also very good, excelling in reasoning and long-form tasks due to its 200k-token context window.


While it offers a flexible pricing model with free and premium plans, the lack of transparency in detailed pricing for advanced tiers makes it harder for businesses to plan.



Perplexity AI chatbot interface

Perplexity’s simple interface and real-time answer synthesis make it highly accessible. Features like follow-up question suggestions and mobile apps enhance usability, though it struggles with complex or nuanced queries.


Real-time web search, inline citations, and collaborative tools like Spaces are valuable features. However, the absence of advanced multimodal capabilities and limitations in handling specialized tasks keep it behind competitors.


Perplexity AI utilizes a combination of advanced large language models (LLMs) to deliver accurate and real-time answers to user queries. Its proprietary models, such as pplx-7b-online and pplx-70b-online, are built upon open-source foundations like Mistral-7B and Llama2-70B, and are fine-tuned to access and integrate real-time web information, ensuring up-to-date responses.  Additionally, Perplexity Pro subscribers have access to the latest AI models from OpenAI and Anthropic, providing a diverse range of advanced AI capabilities. 


The free plan is robust, and the $20/month Pro plan offers great value with advanced models and unlimited uploads. The $40/seat enterprise plan adds flexibility for businesses. Transparent and scalable pricing earns a high score.



Gemini AI chatbot interface

Gemini offers natural language interaction, multimodal input, and seamless integration with Google's ecosystem, which improves usability. However, performance inconsistencies and feature gaps compared to legacy systems like Google Assistant reduce its overall score.


While Gemini includes multimodal integration, advanced reasoning ("Flash Thinking"), and agentic task execution, its current features are still evolving and less mature compared to competitors, impacting its versatility and robustness.


Gemini 1.5 Pro achieves moderate scores: MMLU (74.1%) and HumanEval (71.9%), indicating it is suitable for basic reasoning and coding tasks but not as robust as Claude or GPT-4o. The 1,000,000-token context window stands out for scalability, but lower scores in benchmarks for coding and specialized reasoning lower its comparative rank.


Competitive tiered pricing starting with a free plan and scaling up to $19.99/month for advanced features like extended token contexts and developer tools. Its flexibility remains a strong point.
