Frequently Asked Questions
Quick answers to common questions about Subarb.
Does it work on Mac?
macOS support is coming soon. Subarb currently runs on Windows 10 and 11.
What does it do with my Gmail?
Subarb connects via read-only IMAP to parse billing receipt emails from AI platforms. It never reads personal emails — only messages from known billing senders like billing@anthropic.com and receipts@openai.com.
Is there a subscription fee?
No. Subarb is free during beta. No credit card, no trial period, no expiration.
What AI platforms does it support?
30+ platforms including Claude, ChatGPT, Cursor, Gemini, Perplexity, GitHub Copilot, Windsurf, Midjourney, and more.
The problem is invisible
You're paying for AI everywhere. But nobody shows you the full picture.
Too many charges
Four AI charges on your card this month. You're not sure what half of them are actually for.
Paying for things you barely open
You pay for Claude and ChatGPT. You mostly use one. The other renews quietly every month.
Renewals catch you off guard
You meant to cancel Grok three months ago. You didn't. It's still charging you.
