AI Prompt Generator for ChatGPT, Midjourney and Sora

About this AI Prompt Generator

Writing a good prompt is often the difference between a generic output and a result that feels truly useful. This AI Prompt Generator is designed to help you structure clear, detailed instructions for popular tools like ChatGPT, Midjourney, and modern video generators such as Veo and Sora. Instead of starting from a blank page, you fill in a few key fields (goal, subject, context, style, constraints), and the generator produces a ready-to-use prompt you can paste directly into your favorite AI.

The idea is simple: a strong prompt usually answers “what you want”, “what it should look like”, and “what must not happen”. For text assistants, this means defining the role (expert, teacher, copywriter), the objective, the audience, and the required format (bullet list, steps, code, tone). For image generation, it means describing the subject, environment, lighting, composition, and style — and optionally adding constraints such as aspect ratio or negative elements you want to avoid. For video generation prompts, clarity matters even more: the scene, actions, camera movement, pacing, mood, and duration should be explicit. This tool guides you toward that structure without forcing you to learn a complex prompt framework.

Practical examples include: creating marketing copy for a landing page, generating a clean logo concept, writing a job description, building a study plan, drafting an email, producing a cinematic short video idea, or describing a hyper-realistic product photo. If you switch the “Mode”, the generator adapts the prompt layout for the target AI. You can also choose the output language, which is useful when you want English prompts for better model compatibility, or French prompts for local content and communication.

Everything runs locally in your browser. This page does not call external AI APIs and does not upload your inputs. It simply helps you craft better prompts, faster. If you want to iterate, try changing only one field at a time (style, detail level, constraints) and generate several variants — that small habit usually improves results more than rewriting everything from scratch.

Tip: if you are using video generators, always include format constraints like “9:16”, “8 seconds”, and whether you want subtitles, voice-over, or on-screen text. Consistent constraints reduce randomness.
