What it is

Grammarly

A browser extension, desktop app and keyboard that checks and rewrites your writing wherever you type. The company behind it is now called Superhuman; the product keeps the Grammarly name.

Wispr Flow

A system-wide dictation tool for Mac, Windows and phones. Speak naturally and it removes filler words, fixes grammar and formats the text in whatever app you are typing into.

Best for

Grammarly

Coaches who write a lot of client messages, especially in a second language. It catches the typo in a welcome email before a new client does.

Wispr Flow

Coaches who think faster than they type. Dictating session notes right after a call captures far more than typing them later.

Watch out for

Grammarly

Accept its rewrites and your messages start to sound like everyone else's. Use it as a proofreader, and keep your own voice for the actual coaching.

Wispr Flow

Dictation is processed in the cloud. Be as careful about speaking client details into it as you would be about pasting them.
