Speechly

Speechly.io is a native macOS speech-to-text dictation application built to help professionals, agencies, and developers convert their spoken thoughts into polished text. Rather than serving as a standard, turn-taking virtual assistant or generating a raw, unrefined voice transcript, Speechly functions as a background copilot. Users simply hold down the spacebar to speak naturally across more than 150 compatible apps, and the underlying AI instantly converts that verbal stream into structured, usable writing.

The application goes beyond simple word-for-word voice typing by applying natural language understanding to your spoken sentences. It features a specialized "Email Mode" alongside various selectable formatting tones—such as professional, casual, friendly, assertive, or gentle. When you speak, the system automatically cuts out repetitive phrasing and awkward pauses, fixes grammatical errors, and transforms the raw dictation into a well-organized layout featuring natural greetings, clean paragraphs, and clear calls to action.

To balance speed, safety, and correctness, the application allows users to route their voice processing across three distinct AI execution layers:

Cloud Engine: Engineered for maximum processing speed, delivering ultra-low latencies (under 50 milliseconds) where words appear instantly as you speak.

Local Engine: Runs completely on your Mac's internal Apple Silicon neural hardware. It requires no active internet connection, providing total data confidentiality because your audio never leaves your physical device.

Neural & Neural Advanced Engines: Optimizes transcribing accuracy by using advanced deep-learning models that automatically pick up on your unique voice nuances, contextual industry acronyms, and custom vocabulary over time.

Speechly.io is built using 100% native code optimized specifically for macOS systems (running cleanly on Apple Silicon M1, M2, and M3 chips). Because it runs globally at the system level, it integrates into your workflow without requiring you to constantly toggle back and forth between different browser tabs. It works seamlessly within standard business environments like Slack, Notion, Microsoft Outlook, Apple Notes, Gmail, and code editors.
