The AI Chatbot Question
In 2026, three AI chatbots dominate the conversation: ChatGPT, Gemini, and Claude.
All three are large language models. All three can write, summarize, code, and answer questions. All three have free and paid tiers. So which one should you use?
The honest answer: it depends on what you are doing. ChatGPT is the most versatile. Gemini is the most integrated with Google's ecosystem. Claude is the strongest for long documents and careful writing.
This guide compares them honestly — strengths, weaknesses, pricing, context windows, and the use cases where each one wins. It includes real pricing in INR and USD for Indian businesses.
For organisations building custom AI applications on top of these models, Innovative AI Solutions provides AI development and generative AI services.
