Learn from others' missteps. These are the most frequent pitfalls when using Claude.
Users assume all AI has current knowledge
Remember Claude's knowledge has a cutoff. Use Perplexity or Gemini for current information, then bring findings to Claude for analysis.
Many users treat each conversation as isolated
Create a Project for each major initiative. Upload relevant documents once, set custom instructions, and build context over multiple sessions.
Claude sometimes seems to refuse helpful requests due to safety training
Rephrase requests to be more specific about legitimate use cases. Claude is helpful when it understands the context isn't harmful.
Users are used to small context limits and don't think to paste entire documents
Paste entire books, long contracts, or full codebases. Claude 3 supports 200K tokens — about 150,000 words.
Claude is good at many things, but not always the best choice
Use Perplexity for research, ChatGPT for coding versatility, Gemini for Google integration, Claude for writing and nuanced analysis.
