Spark Industries

Building Say2PDF solo. Paper meets AI.

About

Solo founder of Spark Industries, based in Tokyo. After decades in a day job, I rediscovered the excitement I felt as a kid the first time I touched a computer — this time through AI. Say2PDF is our first product: a voice-triggered scanner that turns any book into a PDF just by saying "Yes." Our mission is simple — connect centuries of human knowledge, still trapped in paper, with tomorrow's intelligence. More products on the way.

Say2PDF - Say "Yes" to scan. No buttons, no AI needed.

Say2PDF turns any book into a PDF just by saying "Yes" as you turn the page. No shutter button, no waiting for auto-capture. Most scanning apps make you press a button or wait for automatic detection. Say2PDF captures the moment you say "Yes," so scanning happens at your own pace, hands-free. Each spread is auto-split into left/right pages and compiled into one PDF. Works with Google Drive, Dropbox, and your own server. Free 5-day trial, no card required.
