01 / WHAT IT DOES — AND FOR WHOM

One question, one answer.

You are the one person who has to explain every line of the cloud bill. Costtell takes one line — pasted verbatim from your billing report — and returns a readable explanation of the service that generated it, how the pricing works, and what typically drives the number up.

Sign-in is required to use the decoder. If you sign in, your past lookups are saved for later reference.

02 / HOW IT WORKS

Three steps, no setup.

1. 01

   Copy a line from your bill

   Open your AWS Cost and Usage Report, Azure billing CSV, or GCP bill. Find the line you do not understand. Select it and copy it.

2. 02

   Paste it into Costtell

   The input field accepts any line — service name, SKU description, usage type. Paste it verbatim, no editing needed. Press enter or click the button.

3. 03

   Read the explanation

   The tool returns what the service is, how its pricing works, and what usually drives the cost up. Copy the explanation or save it to your history for later.

03 / WHAT A RESULT LOOKS LIKE

From opaque to plain.

A line that reads like noise in your CSV becomes a couple of paragraphs you can act on.

04 / WHAT IS COVERED

Three providers, real patterns.

Costtell ships with 25+ curated billing patterns covering the most common services. Each explanation is hand-written, not generated.

05 / WHAT IT CANNOT DO

Honest about its edges.

Costtell does one thing. Here is what falls outside that one thing:

• ✕ No real-time cost tracking. It cannot tell you what you are spending right now. It looks at a single past line and says what it means.
• ✕ No recommendations. It does not say whether you should switch to Reserved Instances or move to a different region. It explains the charge; you decide what to do.
• ✕ No multi-account or team features. Each sign-in is one person. No shared workspaces, no approvals, no org-level views.
• ✕ No custom vendor support. The reference data covers AWS, Azure and GCP. If your bill is from a different provider, or contains a custom SKU the tool cannot match, you will see a fallback message.
• ✕ Not a budget alert. This tool does not send notifications, does not watch your spend. It answers questions about individual lines.

06 / A THING YOU MIGHT WONDER

“Could I just Google this?”

You could — if you know the exact service name and you want to dig through AWS docs, community threads, and pricing pages for each line. A bill often has forty. Costtell gives you the answer in the terms your bill uses, in one round trip, without switching tabs.
