Books that keep themselves.
Connect your accounts, and T:0 categorizes what comes in, posts what it can, and asks you about the rest. Here's how to set it up and run it.

Four things to do in your first session — from sign-up to a clear Inbox.
Business profile
Tell T:0 how your company is structured, how it earns, and what it spends on. It shapes your chart of accounts.
Set up your profileConnections
Banks, cards, processors, and payroll — through OAuth, Plaid, an API key, or a CSV upload.
Connect an accountThe Inbox
The queue of transactions that need your judgment. Categorize an expense, match a credit, confirm.
Work the queueAsk T:0
Ask about a balance, a transaction, or a rule in plain language. Actions wait on your approval.
Talk to the agentHow T:0 keeps your books
AI reads your business
Your profile, chart of accounts, and connected data become a set of accounting rules.
Deterministic rules post
The same transaction is always treated the same way. The rules write to the ledger — not the model.
You review what's left
Anything that needs judgment lands in the Inbox, and every entry is traceable in the audit trail.
