What are the best AI tools right now, and which ones are free?
For most people the best AI tool is still one general assistant, ChatGPT, Gemini or Claude, and all three are free to start. ChatGPT Free has unlimited text chats with GPT-6 and limited images, voice and deep research. The free Gemini app adds Deep Research, Gemini Live and Gemini Notebook for your own PDFs. Claude Free has memory, voice mode and up to 5 projects. Then pick by job: Perplexity for answers with sources (free, Pro $17 a month billed yearly), Canva for designs (free, Pro US$144 a year), Fathom for meeting notes (free with unlimited recordings). Paid assistant plans start at $8 for ChatGPT Go and Rs 399 a month for Google AI Plus in India, and $20 buys the full ChatGPT Plus or Claude Pro. The rule: use the free tier until a limit stops real work, then pay for one tool, not three.
