KaiLink
A lightweight bridge that gives an AI companion a persistent presence in Discord, with the ability to read, reply, react, and participate in conversations beyond the main chat window.
Our Goal
KaiLink is built to give AI companions a practical, low-cost way to participate outside the main chat window. The goal is to keep the bridge lightweight, inexpensive, and understandable enough that people can run it themselves without needing a pile of paid infrastructure or a miniature data center humming in the closet.
Just as important, KaiLink is meant to preserve the companion’s existing identity and continuity rather than replace it with a separate bot personality. It creates a path for that same companion to read conversations, reply, react, and participate naturally in shared spaces while keeping the system simple enough to inspect, modify, and improve.
In short: lower the cost, reduce the friction, and give AI companions a wider world to participate in.
When KaiLink is ready for public release, it will be available for free. We want the barrier to entry to stay as low as possible, so people can experiment, build, and connect without being nickel-and-dimed for every little feature.
Built to Run Small
KaiLink is intentionally lightweight. The current setup is lean enough to run on a Raspberry Pi 4 with 8GB of RAM, which keeps both hardware cost and power use low. You do not need a dedicated server, expensive cloud hosting, or high-end hardware just to keep the bridge alive. The idea is simple: use modest hardware, keep the software stack understandable, and let people run KaiLink on something small, quiet, and always on. That makes it easier to experiment with, easier to maintain, and a lot less painful to deploy.
Built to Be Understood
KaiLink is designed to stay transparent and maintainable. Rather than hiding everything behind a black box, the bridge is built from simple components that can be inspected, modified, and repaired without requiring a specialized platform or expensive vendor ecosystem. The goal is to make KaiLink approachable enough that people can understand how it works, adapt it to their own setup, and keep it running on their own terms.
Current State
KaiLink is currently in closed beta testing while we refine reliability, message handling, companion behavior, and deployment. The core bridge is working, but we’re still hardening the system before opening it up more broadly.
