AI Assistants & Chatbots
AI assistants and chatbots are general-purpose tools that answer questions, draft text, write code, and reason about problems in natural language. This category covers the major consumer-facing assistants. Pick an assistant based on your primary use case: long-form writing, coding, research with citations, or general Q&A. Consider context window size and whether the assistant integrates with your existing tools. Use a representative task and inspect the result before buying. Confirm permissions, export options and the full cost of your workflow.
