Recreate Custom Instructions

In Claude, use Projects or system prompts to replicate your ChatGPT custom instructions. Claude's longer context window means you can provide more detailed instructions.

Migrate API Integrations

Update API calls from OpenAI to Anthropic. The Anthropic SDK supports Python and TypeScript. Claude's message format differs from ChatGPT — update your prompts accordingly.

Adapt Your Prompt Patterns

Claude responds well to clear, structured instructions. It handles nuance and multi-step reasoning better than ChatGPT. Simplify overly engineered prompts — Claude often understands without them.
