What's New
We've fully redesigned Prompt Builder and rebuilt it from the ground up for speed, with Instructions, Improve your prompt, Follow-up prompts, Additional context, and Versioning.
We're hard at work on a brand-new landing page and a Chrome extension, both landing in just a few days.
Pick the right type for your task: Standard, Research, Writing, Planning, Agent, Image, Video, Code, or Automation. Prompt Builder tunes the output to the type you choose, or Auto detects the best one for you.

Save reusable instructions for voice, context, and constraints, and have them applied to every prompt you generate. No more re-explaining yourself each time.

Answer up to three quick clarifying questions and Prompt Builder regenerates a sharper, more complete prompt tailored to exactly what you meant.

After each build you get contextual next-step suggestions, from variations to wild-card ideas, so you can keep exploring with a single click.

See the assumptions the engine made while writing your prompt. Full transparency into how your idea became a finished prompt.

Every refine is tracked on a timeline. Compare where you started, and revert to any earlier version whenever you want.

Already have a prompt you use? Paste it into the Optimizer and Prompt Builder analyzes it, asks up to three quick questions, and rebuilds it stronger.

Jump in and turn your next idea into a ready-to-use prompt in seconds.
