## What is Tiekai Guardian?

Tiekai Guardian is an AI operations doctor for your servers. It connects over SSH to inspect your hosts, read logs, and find problems, then performs repairs only after you approve each step.

Unlike tools racing to be "all-powerful", Guardian is deliberately restrained: by default it only does maintenance, and anything that modifies your server pauses and waits for your tap to approve. That is exactly why you can trust it on real production.

FOR OUR SERVICE CUSTOMERS
Guardian is the companion app for Tiekai's server hosting and maintenance service. You activate it once with the license key we issue to you. There is no in-app purchase and no subscription; nothing is sold inside the app.

THE AI IS KEPT ON A SHORT LEASH
Maintenance-first by design: it will not delete data, change environment variables, deploy new code, or scale services on its own. Read-only diagnostics run automatically. Every write action needs your per-command approval, and higher-risk commands carry an extra warning.

WORKS WITH YOUR SERVERS AND YOUR CLOUD
- SSH hosts: any Linux server you can reach over SSH
- Railway, Render, Fly.io, Heroku, Zeabur, Vercel, Netlify, DigitalOcean App Platform, Koyeb
- GitHub repositories: browse and read files, open pull requests, check Actions runs
Every platform goes through the same per-command approval gate.

WHAT IT DOES
- Health checks: load, memory, disk, and service status
- Reads system and application logs to find the actual cause
- Restarts services, with your approval
- Colour-coded risk labels on every command before it runs
- A full audit log of what was proposed, approved, denied, and executed

YOUR CREDENTIALS, STORED SAFELY
Server connection credentials live only in your iPhone's secure storage (iOS Keychain), and the SSH connection goes directly from your device to your own host. AI analysis runs through Tiekai's secure gateway, so you never need an AI key of your own and the app never contains one.

BUILT TO BE UNDERSTOOD
A plain-language in-app tutorial walks you through connecting and reading the risk labels. You do not have to be an engineer.

Requires a license key issued by Tiekai Information Management.
