GoKawiilKobo launches paid Stack service to sync personal ebooks across devices
Kobo introduced Stack, a monthly subscription letting users upload their own EPUBs and PDFs (up to 200MB) to Kobo Cloud, syncing files, reading progress, highlights and annotations across apps and e-readers. The feature arrives as part of a 6.0 software update, currently in beta, and works on newer devices like the Clara BW, Clara Colour, Libra Colour and Elipsa 2E, with older 2018-2024 models to gain support later.
