## FAQ

### Do AI chatbots store my prompts?

By default, yes. ChatGPT, Claude, and Perplexity all store conversation history. ChatGPT and Claude allow you to opt out of training data usage in settings. For sensitive work involving sources or confidential documents, use Ollama to run models locally -- no data leaves your machine.

### Which AI tool is best for analyzing long documents?

Claude has the largest context window at 200,000 tokens (roughly 150,000 words), making it the strongest choice for analyzing lengthy court documents, financial filings, or leaked datasets in a single session. ChatGPT supports up to 128,000 tokens. Perplexity is designed for search, not document analysis.

### Can I trust AI-generated facts for journalism?

No. All large language models can generate plausible but incorrect information (hallucinations). Never publish AI-generated facts without independent verification. Use AI for research acceleration, summarization, pattern identification, and drafting -- not as a primary source. Perplexity's citations help but still require verification.

### Is there a private alternative to cloud AI tools?

Yes. Ollama lets you run open-source language models (Llama, Mistral, Gemma) entirely on your local machine. No data leaves your device. Performance depends on your hardware -- models run slower than cloud services but your prompts and documents remain completely private. See our Ollama review for setup details.

### Which AI tool is best for real-time research?

Perplexity is purpose-built for research with live web search and source citations on every response. ChatGPT can browse the web with its search feature. Claude does not have real-time web access in its base product. For research that requires current information, Perplexity is the strongest choice.
