# Welcome to Investibook

Investibook is an AI-assisted investigation notebook for SREs and support
engineers working on TiDB Cloud. It brings together the artifacts you normally
juggle by hand — Jira tickets, cluster metadata, slow queries, skills, agent
transcripts — into a single workspace so you can reason about an incident end
to end.

You can use Investibook from four places, all sharing the same workspace data:

- **Web app** — the full experience: workspaces, sources, chat, artifacts.
- **CLI** — drive investigations from your terminal and your agent of choice.
- **Feishu Bot** — talk to `investibook-bot` in direct messages, groups, or
  topic threads.
- **Mobile** — read shared workspaces and continue the chat from your phone.
