The reading app in a night
Juan wanted to read a book (Tynan Sylvester's Designing Games), Julia said 'why don't you listen to it', and his mind jumped: make an app of the book. It landed because he already had leverage. Ten months earlier he'd built Koby, a tool to extract highlights and reading stats from his Kobo e-reader, and it still has a small monthly community, so this wasn't starting from zero, it was adding a feature to a foothold that already exists. The gap he saw: no audiobook system lets you easily highlight, and reading-and-listening at once, at 5 or 6x, makes you comprehend far faster. By Sunday night he had an MVP, proven when Julia sat listening-and-reading for three to four hours straight. It uses the device's built-in accessibility text-to-speech (free, works offline), with a Pro tier for cloud sync, better voices, and locked-screen playback. He's explicit that it isn't reinventing the wheel, just improving services that exist, and this time he'll ship it MVP-lean with a price tag from day one, the test (per Sam Altman) for whether a service has real value: build it and charge something.
// trace: where this idea came from
- ↳ video diary @ 40:43 (aprovechando que ya tengo Koby con comunidad, ¿por qué no hacer la app? ya tengo el leverage, no empiezo de cero)
- ↳ video diary @ 42:00 (leer y escuchar a la vez, a 5-6x, hace entender mucho más rápido)
- ↳ video diary @ 55:53 (el test de Sam Altman, para probar si un servicio tiene valor hazlo y ponle un pago)
- ↳ Entry 249-2: Reading, reconsidered (la misma reconsideración de cómo leemos, ahora vuelta producto)
Juan wanted to read a book, Tynan Sylvester’s Designing Games, Julia said “why don’t you listen to it”, and his mind jumped straight to: make an app of the book. It landed because he already had leverage. Ten months earlier he’d built Koby, a tool to extract highlights and reading stats from his Kobo e-reader, and it still draws a small monthly community, so this wasn’t starting from zero, it was adding a feature to a foothold that already exists, “ya tengo la patica adentro” ▸ 40:43. The gap he saw is that no audiobook system lets you easily highlight, and that reading and listening at once, at 5 or 6x, makes you comprehend far faster ▸ 42:00.

By Sunday night he had an MVP, and the proof it worked was Julia sitting listening-and-reading for three to four hours straight. It leans on the device’s built-in accessibility text-to-speech, free and offline, with a Pro tier for cloud sync, better Gemini voices with real intonation, and locked-screen playback. He’s explicit that it isn’t reinventing the wheel, just improving services that already exist ▸ 55:14. And this time he’ll ship it MVP-lean with a price tag from day one, the test he attributes to Sam Altman for whether a service has real value: build it and charge something ▸ 55:53. The cheapest way to find out if anyone wants a thing is to ask them to pay for it…
