It helps AI builders make long instruction blocks easier to review, version, and test.
The browser restructures pasted instructions into headings, bullets, or consistent formatting.
Paste the full instruction block and identify which constraints are mandatory.
Track prompt changes like code when they affect safety, tools, data access, or product behavior.
Formatting happens locally in your browser.

Yes. Even wording and ordering changes can affect model outputs.
Yes when they control production behavior or agent permissions.
Paste scattered role, tool, and output rules to produce a prompt that is easier to review and version.
Reformat policy, context, and response-format notes into tagged blocks for agent experiments.
Normalize wording and headings before comparing behavior across prompt versions or sharing a proposed update.
Move between prompt optimization, reusable templates, variable extraction, few-shot examples, structured-output prompts, schema binding, agent planning, prompt diffs, and system prompt formatting without running an LLM.
