Which AI assistant is best overall?

No single best choice: it depends on your needs. ChatGPT for versatility, Claude for long-form work, Gemini for Google ecosystem integration. Try all three free tiers to find your preference.

Is ChatGPT worth paying for?

Yes, if you use AI daily. ChatGPT Plus ($20/month) offers GPT-4 access, faster responses, and plugins. Free tier is still capable. Value depends on usage frequency.

Which is best for coding?

ChatGPT and Claude excel at coding. ChatGPT handles more languages. Claude better for reviewing and analyzing code. Gemini adequate but weaker. Try both for your language.

How do they differ in privacy?

All collect usage data by default. OpenAI doesn't use free tier conversations for training (can be disabled). Claude is privacy-focused. Gemini integrates with Google ecosystem. Check privacy settings for each.
