How I stopped getting surprised by my AI API bills

If you've built anything on top of GPT, Claude or Gemini, you've probably had the moment: everything's working, users are happy, and then the bill arrives and it's way more than you expected.

The tricky part isn't the cost itself, it's not seeing it coming. Each provider shows spending in its own separate dashboard, so it's easy to miss what's adding up until the bill lands.

So I built AI Spend Tracker.

What it does

• Connects to OpenAI, Anthropic, Gemini, Grok, OpenRouter and DeepSeek, plus any other tool you enter by hand
• Shows one monthly total across all of them
• Sends a heads-up by email, Slack or Discord at the budget points you choose
• Flags sudden spikes and warns you if you're on pace to go over

A fun technical bit

Every provider reports spending differently. OpenAI and Anthropic have cost report APIs. Gemini doesn't have a simple one, so it reads your own Google Cloud billing export. DeepSeek only shows your balance, so the tracker watches how much it drops between checks.

Try it

There's a live demo on the homepage, no signup needed: aispendtracker.online

It's free for one provider. I'd love to hear what you'd want it to track next!
