What is Midsummerr?

Midsummerr is an AI audiobook production platform for authors, publishers and audio studios. Midsummerr produces audiobooks in 56 languages as a single narrator, a full cast with a distinct voice for every character, or a cinematic full production with music and sound effects.

Martin: Martin is Midsummerr’s AI audio director. Ask in plain words, such as “let her whisper the last line,” and Martin adjusts the delivery, voice, pacing, pronunciation, music or sound effects. Midsummerr is the only audiobook platform with an AI audio director.
Price: On Midsummerr a 90,000-word book costs $135 (single narrator), $337.50 (full cast) or $450 (full production). The first 5,000 words are free.
Speed: Midsummerr generates a full novel in a few hours. How long you refine it is up to you; a finished audiobook can ship in days.
Publishing: Midsummerr exports masters formatted for Apple Books, Spotify, Kobo and Google Play.
Rights: Authors keep the rights to their manuscript and own the finished audiobook.
Narrators: Midsummerr turns a human narrator’s recording into a full cast, keeping the narrator’s narration.

Meet your new director.

Every book deserves a director, someone that will help you get every scene as you imagined it, without tedious editing. Just ask him!

The Last Ferry217

She had rehearsed it all the way down the hill, every word of it, and now that he stood in front of her none of it would come.

“Go on,” she said. “I won’t stop you.”

He picked up the case. He set it down again.

Somewhere below them the ferry sounded its horn, twice, the way it always did, and neither of them looked towards it.

“It’s only a year,” he said.

She nodded, because it was easier than saying that a year was exactly the length of time in which everything could change.

she’s almost crying
