Where the AI runs, where your data lives, and what the server does and does not see.
The promise
Nothing you upload leaves your browser.
- Financial data, vendor data, item data and contract terms are processed entirely on your device.
The models
- AI runs in your browser via WebGPU. Model weights download once and cache locally.
The data
- DuckDB runs in-browser and stores your ledgers, invoices and vendors, persisted with OPFS. There is no cloud database.
The network
- Zero outbound calls for your content. The server handles authentication and billing only — and you can verify this in your browser DevTools, Network tab, while any tool runs.
Portability
A deliberate trade-off.
- Data stays on the device you uploaded it to. Switch machines and you re-upload — by design. The Backup Vault is how you move a whole workspace safely between devices.
