Value proposition
Eliminates copy-paste and context-switching between AI chatbots and desktop apps. IrukaDark understands on-screen context and writes directly into any application with a single keystroke, preserving workflow continuity.
Products and solutions
IrukaDark (flagship desktop Super-Sub AI), Amaroad (MDX slide deck builder for developers), JPGP (Japan Pro Global Platform - freelance engineer marketplace), Cerememory (brain-inspired memory database for AI agents), Copelf (AI workflow tool learning from screen recordings), Tomorrow X 2.0 (AI-developed health supplement)
Unique value
"Super-Sub AI" philosophy — works as a permanent secondary layer on the desktop, separate from primary AI tools. Understands on-screen context automatically, writes into any app, supports 16 languages, and lets users choose their preferred AI model on the fly. No bot-required meeting notes, in-place rewrite/translation, and creative generation (image/video) from the desktop edge.
Target customer
Knowledge workers, enterprise teams, developers, designers, marketers, project managers, executives, students — anyone who does daily PC work across multiple apps.
Industries served
Technology, Business/Enterprise, Consulting, Design, Marketing, Education
Technology advantage
Screen context capture & direct text injection into any application; stacked clipboard with multi-item history; bot-free AI Notetaker for meetings (Zoom, Meet, Teams); multi-model support (users can switch between AI models); Cerememory brain-inspired memory database (open-source); 16-language support; shortcut-first design with 16+ keyboard shortcuts.
How they differentiate
Unlike general AI chat apps that require opening a separate browser tab, IrukaDark works in-place — it understands the screen you're viewing and writes directly into the app you're using. It's positioned as a "Sub-AI" (secondary layer) rather than a primary AI, focused on eliminating the small friction of everyday PC tasks rather than heavy reasoning or complex workflows. It also supports choosing from multiple AI models on the fly.
Main competitors
