Prompt Builder

Fill the 5-part skeleton — Role / Task / Context / Rules / Bans — and get a structured prompt that outperforms vague asking. Scenario presets included. Runs 100% in your browser.

Scenario presets (click to fill, then adapt)

① Role — give the AI a professional identity ② Task — one verb + one deliverable ③ Context — your facts (facts, not conclusions)

④ Requirements — checkable items, one per line ⑤ Bans — what NOT to do (highest-leverage field)

Skeleton completion: 0 / 5 — simple tasks need 3 fields; complex tasks deserve all 5.

Why structure fixes robotic outputs

Mediocre AI output is almost always an input-density problem: a missing role makes it pull from the wrong knowledge base, missing context makes it answer with "the internet's average," and no bans let it pad with safe filler. The 5-part skeleton translates "here's what I want" into language it can execute.

A self-check: hand the generated prompt to someone who doesn't know your goal. If they could carry out the task from it alone, the prompt is good — the AI is no different.

FAQ

Is what I type sent anywhere?: Not by this tool. But once you copy the generated prompt into a chatbot, that service's privacy policy applies — anonymize sensitive details (client names, internal data) before pasting.
My scenario isn't in the presets — now what?: Presets are starters. Clear and fill the skeleton by hand; after three uses you'll have the skeleton memorized and the tool becomes optional.
Why a "Bans" field?: Telling the AI what NOT to do raises quality faster than adding requirements. Three near-universal bans: don't invent data, no filler phrases, cap the paragraph length.
