ChatGPT review

ChatGPT is the most complete assistant on this list and very close to Claude for everyday writing. Every plan includes unlimited text chats, and the free tier also offers limited image creation, voice, deep research and memory. Go, at $8 per month in the US, adds more messages, uploads and longer memory, though OpenAI says that plan may include ads. Plus, at $20 per month, brings advanced reasoning models, expanded deep research, Projects, scheduled tasks and custom GPTs, which are useful for saving a house style or a repeated brief. Pro is for heavy research and coding use. For writers, the extras matter less than the core drafting, and here Claude and ChatGPT trade blows. ChatGPT wins if you also want images and voice in the same place. Pro is now sold in three usage tiers, so check the current price before you budget for it.
