How it works

Three steps. Literally.

No app-switching or manual copy-pasting. Flash works silently in the background, right where your cursor is.

01
Fn

Hold Fn

Just press a single key. Whether you have Slack, a code editor, or a browser open, the app instantly starts listening.

02

Just speak

Speak completely naturally, pause whenever you want, and use your industry jargon. The assistant intelligently removes any stutters and flawlessly handles a smooth mix of languages.

03

Release and done

Formatted, ready-to-send text instantly appears in your active window. Say goodbye to manually fixing typos and missing commas forever.

Features

More than just dictation.

Flash is an intelligent writing assistant that understands the context of your work, learns your vocabulary, and saves you hours of monotonous typing.

Pro

An always-present assistant

Instead of searching for information in separate browser windows, just ask your assistant out loud. Flash will analyze the context of what’s on your screen, then generate and paste a thoughtful, ready-made answer directly into your text editor or messenger.

Edit text with your voice alone

Editing text has never been this intuitive and fast. Simply select any passage, press a key, and tell the assistant to translate a sentence, shorten a paragraph, or give it a more formal tone. In a split second the polished result replaces the old text on your screen.

Floating Teleprompter

Video recording and presenting become completely stress-free thanks to a built-in prompter that intelligently follows your voice. The floating screen auto-scrolls text at your natural pace, and AI can pre-enrich your script with suggestions for breathing pauses and word emphasis.

Your custom dictionary

You can easily teach the app your unique jargon by adding regular client names, tricky medical terms, or specific corporate abbreviations. From that point on, the assistant always spells them correctly, saving you precious time on manually fixing the same words over and over.
