ochiwa
Apps that earn their
place on your screen.
A small studio crafting native macOS software and AI-powered web tools. Made with care, shipped when they're ready, built to last.
The apps
Two products. Zero filler.
Each app is built around one sharp idea — a better way to read on Mac, and a faster way to ship video on TikTok Shop.
RealBook
A tactile PDF reader that turns pages like a real book. Weight, paper grain, binding thread — reading that feels alive.
- 3D page flips with physics-aligned easing and real-time shadows
- Book thickness breathes as you read — left/right stacks redistribute
- Four themes: Classic Leather, Dark Library, Navy Binding, Forest
- Sticky notes powered by on-device AI for instant page summaries
HookCraft
Paste a product description, get scroll-stopping TikTok Shop hooks, a 30-second script, and tuned hashtags in eight seconds.
- Three first-3-second hooks, optimized for the algorithm
- Full 30-second script broken into timed visual and audio cues
- Hashtag set tuned for the TikTok Shop discovery feed
- Free, anonymous, zero signup — single-page studio
How we build
Craft over volume.
ochiwa is small on purpose. We ship fewer things, and we ship them well.
Native first
When a tool belongs on a Mac, it's built in Swift — not wrapped in a webview. Real pixels, real menus, real responsiveness.
Private by default
No accounts, no tracking, no ads. Your files stay on your device, your prompts stay between you and the model.
Ship when ready
No artificial release cadence. We launch when the product is genuinely good — and keep polishing after.
Say hello.
Feedback, ideas, or just curious — we'd love to hear from you.
