Talk a book into existence. It will not write a word of it.

Say it out loud and it is written down. Tiro reads over your shoulder: he cuts, he structures, he tells you when a paragraph is you clearing your throat. He does not write your prose and he cannot — every word that ends up in your book came out of your mouth.

He answers in the margin, never in the manuscript

Make this into a chapter for me.

No. There are two ideas here and you have not decided which one you believe. Everything before “we keep the sound and lose the room” is you clearing your throat. Shall I cut it?

What happens while you talk

It writes down what you said. Words land about half a second behind your voice, punctuated, in the paragraph your cursor is in.
He cuts, moves and titles. Say what you want done. Anything he puts on the page has to be liftable from a sentence you actually spoke, and that is checked in the code rather than promised here.
He shows you where to keep going. Ask him to scaffold a chapter and he marks what is missing and names it. Press a mark and your cursor is there, waiting for you to say it.
It reads the draft back to you, aloud, which is how you hear the sentence that does not work.
You can take the manuscript as PDF, Word, EPUB, LaTeX or plain markdown, whenever you like — and all of it at once if you are leaving.

What it costs

Free	nothing	1 hour of fast transcription a month, 20 instructions
Writer	€12 a month	10 hours, 200 instructions — a book a quarter
Author	€29 a month	40 hours, 600 instructions — dictating most days
Custom	tell me	Your work does not fit the three above — a thesis with citations, a script, a language it has never heard. Say what you need and we will talk about building it.

Run out and nothing stops. Dictation carries on with the transcriber on our own machine, which is slower and punctuates less well and costs nothing to run. There is no bill for going over, and no sentence interrupted to sell you something. If you want more instructions before the month turns, a hundred more cost €7 and do not expire — bought when you decide to, never charged automatically.

The fool’s cap above is a real watermark, from a sheet of paper made in 1677. Paper carrying it was called foolscap, and the name outlived the mark.
