See exactly which customers are burning your AI margin
AI Observly attributes every LLM and API dollar to the customer who spent it — so you know who's profitable and who's quietly eating your margin, before it shows up on your P&L.
Automatic Cost Ledger, Per Customer
Every API call and token is tagged to the customer_id that triggered it — automatically, from day one. No manual tagging, no spreadsheets, no engineering project.
Margin-Negative Alerts
Get flagged the moment a customer's AI spend crosses what they're paying you — not 30 days later when the provider invoice lands.
Top 5 Free, Unlock the Rest

Customer names are always visible. Cost, revenue, and margin unlock as you upgrade.
Know your true cost-to-serve, per customer
Revenue per customer is easy. Cost-to-serve for AI-powered products isn't — until now. AI Observly pulls usage straight from your LLM and API providers and rolls it up by customer, so “cost to serve” stops being a guess.

Catch margin-negative customers before renewal
A single power user on a flat-rate plan can quietly wipe out the margin of ten normal ones. AI Observly surfaces margin-negative accounts as they happen, so you can fix pricing, add usage limits, or have the conversation before the renewal — not after.

Built for founders, not for engineers

Stop finding out about margin problems from your bank balance
