LLM Batch Request Builder
Local formatting only: this tool builds JSON text in your browser. It does not send prompts anywhere and does not connect to any provider or account.
How to use this tool
- Enter one prompt per line, then press Generate.
- Copy the JSON array. Each entry has an id and the prompt text.
- Use Load sample for two example prompts.
Worked example
For the prompts “Summarise this paragraph” and “List three tips”, the tool builds a JSON array with two entries: id “req-1” with the first prompt, and id “req-2” with the second.
What this tool does not do / Limits
This tool only formats text into JSON. It does not send requests, check prompt quality, or guarantee that any provider accepts this exact format; adapt the JSON to your provider's documented format.
Frequently asked questions
Does this send my prompts to an AI provider?
No. Everything stays in your browser; the output is text for you to use in your own workflow.
Can I add extra fields?
Not in this tool. Copy the JSON and add fields such as model or temperature in your own editor.
