Sayline is a native macOS application designed to replace traditional keyboard typing with voice dictation. It enables users to speak naturally and have their words instantly transcribed into text fields across various applications, offering a more productive way to create content.

The app works with any text field in applications like Gmail, Slack, VS Code, Notes, Canva, Google One, Grammarly, ChatGPT, Obsidian, Claude, Microsoft Word, Notion, Google Docs, Cursor, Linear, Microsoft 365, Outlook, LinkedIn, Todoist, Google, Zoom, Discord, WhatsApp, Telegram, and Superhuman. It features global hotkeys for quick activation and runs entirely on-device, ensuring privacy and security.

Sayline operates by processing voice input locally using NVIDIA Parakeet and MLX technologies. Users simply press a hotkey, speak naturally, and the transcribed text appears instantly in the active application without requiring an internet connection.

The primary benefit is increased productivity, with dictation being up to 4x faster than manual typing. It allows users to create content at the speed of thought, eliminating the bottleneck of keyboard input. Use cases include drafting emails, writing Slack messages, creating AI prompts, and composing documents across various productivity tools.

Sayline targets Mac users seeking to enhance their productivity through voice dictation. It integrates seamlessly with numerous popular applications and emphasizes privacy by keeping all data on-device. The app is available as a native macOS application with plans for future Windows and iOS versions.
