Claude Prompt for Proofreading a Text

Proofreading text is one of Claude's most powerful uses. Whether you are a writer, student, professional, or content creator, spelling, grammar, and syntax errors can undermine the credibility of your writing. Claude excels at identifying and correcting these errors thanks to its deep understanding of the French language, including complex agreements, irregular conjugations, and typographic subtleties. Unlike a simple autocorrect tool, Claude understands the context of each sentence, allowing it to detect errors that standard tools miss: false cognates, anglicisms, awkward repetitions, or register inconsistencies. By using a well-structured prompt, you get not only a corrected text but also explanations for each modification, helping you improve your language skills. This approach transforms correction into continuous learning, tailored to your level and specific needs.

Sora Prompt for Writing a Video Script

Sora, the artificial intelligence model developed by OpenAI, is not limited to generating videos from text. It is also a powerful tool for structuring and writing compelling video scripts. By leveraging its contextual understanding and content generation capabilities, you can obtain complete scripts with scene-by-scene breakdowns, visual instructions, dialogues, and narration. Whether you produce content for YouTube, advertisements, corporate videos, or short films, a well-constructed prompt allows Sora to generate a script that respects the narrative codes of the video format. The challenge is to provide enough context — tone, target audience, duration, goal — for the model to produce a document that can be directly used by a production team. In this guide, we offer an optimized main prompt as well as three variants adapted to your expertise level, to turn your ideas into professional video scripts ready to be shot.

Midjourney Prompt to Write a Blog Post

Midjourney is primarily an AI-powered image generation tool, not a text writer. However, it plays a strategic role in creating blog posts by producing original, impactful visuals perfectly suited to your content. A post illustrated with unique images generated by Midjourney immediately stands out from competitors who use generic stock photos. Custom visuals increase time on page, improve click-through rates from social media, and reinforce your blog's visual identity. Whether you need an eye-catching cover image, stylized infographics, abstract concept illustrations, or mood visuals to accompany your sections, Midjourney allows you to create exactly what your article needs. In this guide, we offer optimized prompts for generating professional illustrations to enrich your blog posts, regardless of your field: technology, lifestyle, marketing, travel, or personal development. Each prompt is designed to produce consistent images with a professional editorial tone.

ChatGPT Prompt to Write a Press Release

Press releases remain an essential communication tool for any company wishing to disseminate information to the media. Yet their writing follows very specific codes—inverted pyramid structure, factual tone, calibrated quotes—that even PR professionals take time to master. ChatGPT changes the game by enabling the production of a structured, professional, ready-to-send press release in minutes. By providing the model with key information (who, what, when, where, why), you get a first draft that respects journalistic conventions: a catchy headline, a concise lead, a developed body with quotes and data, and an "About" paragraph for the company. The AI particularly excels at maintaining the neutral and informative tone expected by journalists, while incorporating storytelling elements that capture attention. Whether announcing a product launch, a funding round, a strategic partnership, or an event, the following prompts will guide you to produce a press release that meets professional PR standards.

Prompt ChatGPT for Writing Prospecting Emails

Email prospecting remains one of the most powerful levers for business development, but writing messages that grab attention and generate replies is a real challenge. Between ignored subject lines, overly generic messages, and overly aggressive approaches, most prospecting emails end up in the trash. ChatGPT changes the game by allowing you to generate personalized prospecting emails structured according to the best practices of commercial copywriting. By providing the model with the precise context of your offer, your target, and your value proposition, you get emails that respect the codes of modern prospecting: punchy hook, recipient personalization, clear value proposition, and non-intrusive call to action. Whether you're prospecting B2B or B2C, cold or follow-up, ChatGPT helps you industrialize writing while maintaining a human and engaging tone. No more writer's block or hours spent rephrasing the same message: you can now produce entire email sequences tailored to each segment of your audience in minutes.

Gemini Prompt for Writing an Internal Memo

Writing an internal memo is a delicate exercise that requires clarity, conciseness, and a tone adapted to the company culture. Whether it's announcing a reorganization, a new partnership, or an HR policy update, every word counts to maintain employee trust. Gemini, Google's AI, excels at this type of task thanks to its ability to structure information hierarchically and adapt language register to context. By providing a well-constructed prompt, you get a professional memo that respects corporate communication codes: clear subject, concise context, highlighted main message, and explicit call to action. Gemini's advantage lies in its fine understanding of tone nuances—it distinguishes a neutral informative memo from a mobilizing announcement or a crisis communication.

Claude Prompt for Writing a Video Script

Writing a video script requires creativity, structure, and a sense of pacing.

Claude excels at this task thanks to its ability to understand format constraints, adapt tone to your audience, and structure a compelling narrative from the opening hook to the final call to action. By providing Claude with precise information about your topic, target, desired duration, and style, you get a script ready to be read on camera or sent as voiceover. The AI naturally handles transitions, sequence breakdowns, and the alternation between informative and emotional moments. Whether you're a solo content creator or leading a production team, using Claude for your video scripts lets you go from idea to filming in a fraction of the usual time, while maintaining a consistent professional quality level.

DALL-E Prompt for Translating Text

DALL-E, OpenAI's image generation model, offers an often underestimated capability: embedding translated text directly into visuals. Instead of translating text in a conventional way, DALL-E allows you to create images containing text in a target language, which is particularly useful for localizing visual content, creating multilingual posters, marketing mockups, or educational materials. By combining translation with visual generation, you get a finalized visual with the translated text embedded in a single step, perfectly styled and contextualized. This approach is ideal for content creators, international marketers, and language teachers who want to quickly produce multilingual visual materials without using a translation tool and then a design software separately. Mastering the right prompts helps achieve precise results where the translated text is legible, well-positioned, and consistent with the overall design of the image.

Midjourney Prompt for Writing an Internal Memo

Midjourney is an artificial intelligence image generation tool that can transform your internal memos into impactful visual materials. Rather than sending a plain block of text that no one reads, you can create professional accompanying visuals that capture your colleagues' attention the moment they open the message. Whether illustrating a restructuring announcement, an internal policy change, a company event, or the launch of a new project, Midjourney lets you produce custom images that reinforce your message and reflect your organization's visual identity. Studies show that internal communications paired with relevant visuals achieve a 65% higher read rate compared to text-only messages. In this guide, you'll find optimized prompts for generating illustrations suited to every type of internal memo: official announcements, executive memos, HR communications, and newsletters. Each prompt is designed to produce visuals with a controlled corporate tone, avoiding the pitfalls of overly whimsical images disconnected from a professional context.

By providing the context, recipient, and goal of your message, you get a structured email, tailored to the desired register, and ready to send.
