GitHub Copilot Prompt for Translating a Text

GitHub Copilot, the AI development assistant created by GitHub and OpenAI, is not limited to code generation. Integrated directly into your editor (VS Code, JetBrains, Neovim), it can also serve as a powerful translation tool for your multilingual projects. Whether you need to translate localization files (i18n), code comments, technical documentation, or user interfaces, Copilot understands your project context and produces translations consistent with your existing terminology. Its main advantage lies in its ability to maintain source code formatting intact — HTML tags, interpolation variables, JSON keys — while translating only the textual content. This editor-integrated approach avoids back-and-forth with external tools and ensures your translations respect your codebase's technical conventions. Here is an optimized prompt to fully leverage GitHub Copilot in your translation tasks.

DALL-E Prompt to Correct Text

DALL-E, OpenAI's image generation model, offers a little-known feature: the ability to correct text directly embedded in an image. Whether you've generated an image containing a typo, a misspelled word on a poster, or illegible text on a marketing visual, DALL-E allows you to intervene using its editing tool (inpainting). By selecting the area containing the erroneous text and providing a precise prompt, you can ask the model to regenerate only that portion with the corrected text. This approach avoids recreating the entire image and preserves the original style, colors, and composition. However, it's important to note that DALL-E remains an image generator and not a word processor: typographic rendering can vary, and long or complex texts sometimes require several attempts. To maximize your chances of success, use structured prompts, specify the desired font, and limit the amount of text to correct in a single pass. This guide provides you with the optimal prompts for achieving reliable text corrections in your DALL-E generated images.

GitHub Copilot Prompt for Summarizing a Document

GitHub Copilot, the AI assistant developed by GitHub and powered by OpenAI models, is not limited to code generation. Integrated directly into your editor (VS Code, JetBrains, Neovim), it also excels at summarizing technical documents, specifications, README files, or any documentation in your project. Summarizing a document is a common task for developers who need to quickly understand the content of a documentation file, a detailed bug report, an RFC, or a lengthy changelog. By using Copilot Chat with a well-structured prompt, you can get a clear, hierarchical summary in seconds without leaving your development environment.
