Anthropic's Claude series (including Claude 3.5 Sonnet and Opus) is famous for its massive context window. So why would you ever need a Claude prompt splitter? The answer lies in the difference between "reading" and "following instructions."
The "Lost in Context" Challenge
Even though Claude can read an entire book in one prompt, its ability to follow complex, multi-step instructions decreases as the prompt length increases. This is especially true for tasks like data extraction, code refactoring, or detailed analysis. By using a splitter, you focus Claude's "attention" on smaller, manageable segments.

Use Claude SplitterBenefits of Splitting for Claude
- Higher Precision: Smaller chunks mean Claude is less likely to skip over fine details or ignore specific constraints.
- Structured Responses: Feeding text in parts allows you to get a summary or analysis of each section before moving to the next.
- Sequential Processing: Perfect for long documents where the later parts depend on the logic established in earlier ones.
How to Use the Claude Splitter
- Set your limit: While Claude can handle more, we recommend 20,000 characters for maximum instruction following.
- Use the "Wait" Prompt: Tell Claude at the start: "I will provide a long document in parts. Please acknowledge each part with 'OK' and do not begin the analysis until I send the final part."
- Consolidate: Once all parts are in, give your final instruction.
