Best AI Chatbots & Assistants 2026 - Frequently Asked Questions
What is the difference between ChatGPT and Claude?▾
ChatGPT (OpenAI) and Claude (Anthropic) are both capable general-purpose assistants. Claude tends to have a longer context window and excels at nuanced writing and instruction-following. ChatGPT has a larger plugin/tool ecosystem. Both offer free and paid tiers — try both to see which fits your workflow.
Can AI chatbots be used for customer support?▾
Yes. AI chatbots handle FAQs, order lookups, and basic troubleshooting 24/7 at scale. Platforms like Intercom Fin and Zendesk AI sit on top of your help center and resolve tickets without human agents. Complex or sensitive issues still require escalation to human support.
What is a system prompt?▾
A system prompt is an instruction set given to an AI chatbot before the conversation starts — defining its role, tone, constraints, and knowledge focus. It is invisible to end users but shapes every response. Building a good system prompt is key to deploying a chatbot that behaves consistently.
