When to use ChatGPT
ChatGPT has the largest user base and broadest third-party integration ecosystem. Its web browsing feature, image generation (DALL-E), and plugin marketplace make it the most versatile general-purpose AI assistant. For tasks like drafting interview questions, summarizing press releases, generating data visualizations, or writing code for scraping projects, ChatGPT is a solid default. OpenAI's training data practices and past security incidents mean you should never input confidential source material.
When to use Claude
Claude is the strongest choice for document analysis. Its 200,000-token context window can process roughly 500 pages in a single conversation. Upload a court filing, financial disclosure, or leaked dataset and ask questions about it. Claude tends to be more cautious about unsupported claims than ChatGPT, which is useful for journalism. Anthropic built Claude with a focus on reducing harmful outputs. Disclosure: this site was built with Claude.
When to use Perplexity
Perplexity is purpose-built for research. Every response includes source links, making it faster to verify claims and follow citation trails. For backgrounding a story, checking facts, or exploring what has already been published on a topic, Perplexity is the most efficient starting point. It searches the live web, so it can surface recent developments that other AI tools miss due to training data cutoffs.
The privacy problem with all three
All three services are cloud-based. Your prompts are transmitted to and processed on their servers. All three retain conversation data by default. Never input confidential source information, unpublished investigation details, or sensitive documents into any cloud AI service. For sensitive analytical work, use Ollama to run open-source models locally on your own hardware.
Frequently asked questions
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.
