FAQ
Questions, answered.
What is AI Spendbook?
AI Spendbook is financial planning and analysis (FP&A) software for AI spend. It shows what a company spends on AI providers, attributes the cost to customers, features and teams, compares models on the company's own usage, forecasts spend with ranges, and answers questions with citations to the underlying data.
Which AI providers does AI Spendbook support?
Anthropic and OpenAI connect through their admin usage and cost APIs. Google Gemini connects through the Cloud Billing export to BigQuery. Any other provider can be added with CSV or JSON imports, the Python SDK (pip install spendbook) or the HTTPS ingestion API.
How does AI Spendbook reconcile provider billing with app telemetry?
Provider billing sets the total for each day and provider. Request-level telemetry from your app or the SDK explains that total by customer, feature and user. The two are never added together. Billed spend that telemetry does not cover is shown as unattributed, and days the provider has not billed yet are labelled as estimates.
What data does AI Spendbook read?
Usage and cost reports from provider admin APIs, the Cloud Billing export for Gemini, the tables or collections you map in Supabase, Postgres or Firestore (only the columns you approve), Stripe invoices if you connect revenue, and events you send with the SDK or API. It only reads from these sources.
Is AI Spendbook free?
Yes. AI Spendbook is free for a limited time, with every feature included and no credit card required. If paid plans are introduced later, users will be told before anything changes.
Does AI Spendbook store prompts or completions?
No, not by default. The SDK sends token counts, model, latency, status and attribution fields. Prompt and completion text is captured only if a workspace admin turns on content capture and the SDK is configured to send it.
