Best AI chatbots & assistants

We compared the leading AI assistants on writing, reasoning, research, integrations, privacy and price to help you choose the right one.

AI chatbots, also called AI assistants, are general-purpose tools you talk to in plain language. They can draft and edit text, answer questions, analyse files, write code, search the web and increasingly complete multi-step tasks on your behalf.

The market is led by ChatGPT, Claude and Gemini, with strong options from Microsoft, Mistral, xAI and DeepSeek. Most offer a capable free plan and a paid tier around $20 per month.

How to choose the right chatbots & assistants tool

Match the ecosystem you useIf your work lives in Google Workspace or Microsoft 365, the built-in assistant (Gemini or Copilot) saves the most time.
Test on your real tasksGive each assistant the same three prompts from your work and compare how much editing the answers need.
Check privacy settingsLook for options to stop training on your data, and use business plans for company information.
Consider limits, not just pricePaid plans differ mainly in usage limits and access to advanced reasoning, research and agents.

Free vs paid

Free plans are enough to learn and for occasional use. Upgrade to a $15–20 per month plan when you hit limits daily or need deep research, agents or file creation. $100–200 plans are only worth it for very heavy professional use.
