About Hms

Hms, short for "How many subscriptions", is a free calculator that adds up what you spend on AI tools each month and each year.

Who runs it

Hms is built and maintained by ssunibear, an independent developer.

Why it exists

AI tools are easy to sign up for and easy to forget. A chat assistant, a coding assistant, an image generator and a note-taking add-on can each look cheap on their own, yet together they often cost more than people expect, especially when the prices are in US dollars and tax and exchange rates are added at checkout. Hms puts every plan in one list, converts it to your currency, and shows the day each one renews, so you can decide what to keep.

Where the prices come from

Each plan in Hms starts with the monthly price published on the service's own pricing page, billed monthly, in US dollars, before tax. Prices can differ by country, by app store and for annual billing, so every price in the calculator can be edited to match what you actually pay.

Prices are checked against the official pricing pages and the check date is recorded for each service. When a price cannot be confirmed from an official source, it is marked as unverified rather than guessed.

What Hms does not do

• It does not need an account, and it does not send your subscription list to a server. Everything you enter stays in your browser.
• It is not affiliated with, endorsed by or paid by any of the AI companies listed. Product names and logos belong to their owners and are shown only to identify each service.
• It is not financial or tax advice. Check your receipts and your card statement for the exact amounts.
