Let skills in Gemini tackle your most repetitive tasksWhat:Today we’re rolling out skills directly into the Gemini chat globally1. Skills are a reusable set of instructions that tell Gemini how to handle specific tasks. Think of them as saved shortcuts to faster prompting.Gemini can now help you build custom skills from your chats and automatically run them whenever you enter a matching prompt. For bigger tasks, you can stack multiple skills together at the same time — like combining a writing style skill with a brand guidelines skill to create on-brand assets in your voice.Skills will soon replace Gems as the tool for tailoring instructions for specific tasks. To make this transition seamless, we will automatically migrate your Gems into skills when Gems go away. You can learn more about how to transition your Gems into skills by visiting ourhelp center.Why:We want to help you spend less time prompting and more time doing. With skills, you can save your most-used instructions once and run them endlessly – so you can skip the repetitive prompting and jump straight to the results.1currently available to 18+ and coming to more users soon.
