VOICE
Paste a few things you have written and this will measure the rhythm underneath them — sentence length, how much it varies, where you run short. The counting runs in the page itself, so the reading appears as you type and needs no account.
Rather talk than dig?
Eight questions, about ninety seconds each. We transcribe what you say, you read it back, and the answers become the writing behind your profile. The audio is thrown away as soon as the text exists.

What you paste stays in this tab — it is measured here and never sent anywhere. Saving a profile sends the measurements only, and not the writing they came from, unless you ask below for the piece itself to be kept.
Mix a few kinds of writing — an email, a couple of Slack messages, a post. One long document measures that document; several shorter ones measure you. Around 1,500 words gives a stable reading, and a few hundred is enough to see the shape.
