## O que é Shift?

Shift is a text and code editing tool that works across applications on a Mac. It lets users highlight content, invoke the app with a double-tap of the Shift key, and ask an AI model to rewrite, generate, or refine the selected text without switching apps.

The product is built for people who want in-place editing in tools they already use, including code editors and common office apps such as Word, PowerPoint, and Excel. It also supports reusable contexts, chat-style follow-up, custom shortcuts, and prompt libraries for more structured workflows.

## O que Shift pode fazer?

### Quick Edit Mode

Select text in any application, double-tap the right Shift key, enter a prompt, and have the rewritten output replace the selected text directly in place.

### Context

Add up to four context blocks, keep them across prompts, and optionally clear them after each prompt so longer tasks can preserve relevant background.

### Chat Mode

Hold the right Shift key or use the chat icon to switch into a conversation-style workflow, with local chat history and optional memory retention.

### Advanced Shortcuts

Create unlimited custom shortcuts in Settings using double-press, two-key, or three-key combinations, and map them to a model, prompt template, or library selection.

### Library

Store reusable prompts, organize them into categories, and attach documents for longer instructions that need to be reused across tasks.

### Custom API Key Support

Use your own API keys for supported providers, including OpenAI, Anthropic, and Google, with cost and usage control handled in the app.

## Casos de uso

### In-place writing edits

Revise sentences, paragraphs, or drafts directly in the app where they were written, which is useful when you want to polish copy without copying it into another tool.

### Code assistance inside editors

Prompt an AI model to explain, transform, or rewrite code while staying in your editor, reducing context switching during development work.

### Context-aware prompt chains

Keep source material in a context block when a prompt depends on earlier text, such as notes, requirements, or a longer passage that needs continuity.

### Chat-style follow-up

Maintain a running conversation about selected text when the task needs back-and-forth refinement rather than a single rewrite.

### Reusable prompt workflows

Save recurring instructions or specialized prompts in the library so repeatable workflows can be launched from custom shortcuts.
