Why a prompt formatter.
Most prompts people write are messy. A sentence, maybe two, with zero structure. LLMs understand them but the output is always worse than it could be. This tool takes whatever you paste and rewrites it with a clear role, context, task, audience, constraints and output format. Your LLM suddenly knows exactly what you want.
Everything runs in your browser. Nothing gets sent to a server. Your messy prompt stays between you and your clipboard.
Save this inside PromptVault.
The formatted prompt you just got is worth nothing if you paste it, lose the tab and rewrite the same thing tomorrow. PromptVault saves it in a vault you open with Ctrl+Shift+P on any of ten AI platforms. Install it once, use it every day.
