Frequently Asked Questions

Is ChatGPT or Claude better in 2026?

It depends on the task. ChatGPT has more features (image generation, code execution, voice). Claude consistently produces better writing quality and follows complex instructions more precisely. Most serious AI users subscribe to both and use each for its strengths.

What is Claude's context window?

Claude Opus 4.6 has a 200,000-token context window — equivalent to roughly 150,000 words or 600 pages of text. This makes it uniquely capable for analyzing entire books, large codebases, or lengthy research documents that would exceed other models' limits.

Are AI apps safe to use for sensitive information?

All major AI apps warn against sharing sensitive personal, financial, or confidential business information. Prompts are typically used to improve models. For confidential work, use enterprise API access with data protection agreements or self-hosted models. Consumer AI apps are not appropriate for truly sensitive data.
