Cobalt launches app platform for Kobo

Cobalt is compelling infrastructure for turning inexpensive, distraction-resistant hardware into specialized AI terminals, but its narrow device support and hobbyist installation keep it firmly experimental.

• –Separate unprivileged processes and capability checks provide a stronger security model than ad hoc Kobo shell integrations
• –AI Chat, audiobook generation, arXiv reading, and Claude Code/Codex control demonstrate genuinely useful e-ink workflows
• –Independent app and platform releases make the ecosystem easier to evolve than traditional sideloaded Kobo hacks
• –The Rust SDK and browser simulator lower the barrier to building device-native apps without handling framebuffer or refresh logic
• –NickelMenu, KOReader, and limited tested hardware remain serious constraints for broader adoption
