Every SaaS and AI bill, on one screen.
Connect your AI providers and SaaS spend, and WatchTower turns them into one monthly cost view — per source, per month, with the receipts.
How it works
Visibility first. Controls already exist in Sanka; WatchTower adds the meter.
The control layer already exists
WatchTower builds on the governance features that run Sanka today — permissions, logs, and approvals. The meter is new; the controls are proven.
On the roadmap — honestly
Budgets and alerts, cloud providers (AWS/GCP), and seat-license reconciliation come after v1. If one of those is your blocker, tell us on the waitlist — it shapes the order.
Frequently asked questions
Which sources are supported at launch?
Anthropic, OpenAI, Sanka AI usage, and a manual/CSV source for any other SaaS bill.
Where is usage data stored?
In your Sanka workspace, governed by the same permissions and logs as everything else. API keys are stored like other integration credentials and never exposed to the browser.
Does it require a Sanka plan?
WatchTower v1 ships inside Sanka workspaces, so yes — a standalone edition is on the longer-term roadmap.
Can it handle Japanese invoices?
Yes — currency-aware records with JPY defaults, and the CSV source accepts Japanese billing exports.
