Split long text into token-estimated chunks with overlap for retrieval and AI knowledge bases.
Generator
Describe the goal, constraints, and format, then produce copy-ready output that can be refined or saved.
Describe the outcome, format, or constraints.
Create a structured draft or package.
Copy, edit, or save the output.
Paste source text, then choose chunk size and overlap in tokens.
Review chunk cards, token counts, and copy JSON or Markdown chunks.

Prompt, options, and generated output
Turn prompt planning into a package you can copy into an AI tool, API request, or prompt library.
Use RAG Chunking Tool when you need to split long text into token-estimated chunks with overlap for retrieval and AI knowledge bases.
It focuses on deterministic tasks such as token estimates, prompt structure, context budgets, chunking, costs, and structured-output instructions.

Token budget -> context plan -> chunks -> cost -> safety check.
Check whether the prompt leaves room for examples, retrieved context, and output.
Reserve space for instructions, user content, tool messages, and final answer.
Split long source material into overlap-aware chunks for RAG or knowledge workflows.
Estimate API cost and scan untrusted text for prompt-injection patterns.
A: No. It prepares chunk text and metadata you can send to your own embedding pipeline.
A: Start with 400 to 800 tokens for general documents, then adjust based on retrieval quality and answer length.
Estimate AI tokens, words, characters, context usage, and remaining budget for GPT-style prompts.
Plan prompt, retrieved context, reserved instructions, and expected output inside an AI context window.
Convert JSON Schema into copy-ready AI prompt instructions with required fields and output constraints.
Estimate AI tokens, words, characters, context usage, and remaining budget for GPT-style prompts.
Build structured system and user prompts from role, task, context, constraints, examples, and output format.
Plan prompt, retrieved context, reserved instructions, and expected output inside an AI context window.
Estimate per-request, daily, and monthly AI API costs from token usage and custom per-million-token prices.
Build repeatable checks for AI relay or aggregator model claims, then score pasted responses and metadata for mismatch risk.
Analyze pasted AI relay logs for token cost, latency bands, error rate, and model fallback signals.
